Frascold, Solid Energy in district energy initiative
MILAN, Italy, 19 April 2022: District heating systems could be a key technology in achieving the international climate mitigation goals, both those laid out in the Paris Agreement and the more stringent ones set by the European Green Deal. Saying so, Frascold, which manufactures semi-hermetic compressors for the industrial refrigeration and air conditioning sectors, said it has combined with Solid Energy, which specialises in heat pumps powered by renewable energy sources, to contribute to the diffusion of district heating and pave the way to an ecological transition by signing up to numerous projects in Denmark.
Amongst the most recent partnerships, upgrading the Galten plant in the Scandinavian country stands out, Frascold said. The plant has been in operation since 1964 and is capable of powering approximately 2,130 homes, Frascold highlighted.
The collaboration between Frascold and Solid Energy for the Galten facility began in 2019 with the creation of a system able to produce 45,000 MWh per year, obtained from 6 Frascold CXH screw compressors, suitable for use with HC, for 3.5 MW of overall power. The subsequent expansion, in 2021, saw the addition of 12 CXH compressors for an increase in power of 7 MW, Frascold said.
The installed air-water heat pumps absorb heat from the outside air with 34 air coolers for a total of 3,215,000 m3/h and cover 98% of the district heating system’s power consumption – that is, 44.343 MWh – with a SCOP (Seasonal Coefficient of Performance) of 3.11, Frascold said. The plant provides a discharge temperature of 70 degrees C with a return of 38 degrees C, thus achieving a COP of 3.4 calculated by considering an outside air temperature of 8 degrees C, which is the annual average in Denmark, Frascold said.
“We think HC heat pumps are ideal for helping reduce the comfort sector’s environmental impact,” said Karsten Pedersen, Technical Director, Solid Energy. “Cascade systems with R290 and R600a guarantee the best balance of lowering direct and indirect consumption, flexibility of use and costs.
So, for this project, we relied, once more, on Frascold, which has supported us throughout each phase, and thanks to the constant dialogue with the Competence Center team, we have designed the ideal system to respond to the three challenges: Sustainability, performance and efficiency.
The partnership with Frascold is also based on the certified reliability of its wide range of hydrocarbon solutions: It is, in fact, the only manufacturer on the market with compressor sizes around 1,000 m3/h, which are perfect for our project and comply with ATEX directives for use in zone 2.”
Fabrizio Diotallevi, Frascold Sales Area Manager, North Europe, said: “Denmark is one of the most advanced countries in terms of district heating, and approximately 1.7 million homes, or 64% of the total, are powered by these systems, of which 61% already use energy from renewable sources.
A continuous improvement process is in line with the objective to completely eliminate fossil fuels in the segment by 2030. With the numerous plants brought online with Solid Energy, we are proud to contribute to this ambitious project, which we hope will be replicated in other countries.
This new success story with Solid Energy is another example of our expertise in building heat pump compressors, which we have gained through years of international partnerships using this technology that, in the near future, will be the basis for virtuous heating and zero environmental impact.”

Danfoss breaks ground for ‘supermarket of the future’
NORDBORG, Denmark, 14 April 2022: Engineering firm, Danfoss recently hosted a ground-breaking ceremony for the construction of what it described as one of the world’s most energy-efficient supermarkets.
Making the announcement through a Press release, Danfoss said the supermarket, scheduled to be ready in mid-2023 and spanning an area of 1,500 square metres, is situated next to Danfoss’ headquarters, in Nordborg, and is expected to lead the way for supermarket chains around the world to develop climate-friendly and sustainable stores with technologies that already exist today.
Built with energy-efficient refrigeration and heating technology, solar roof panels and charging points for electric cars, the Smart Store supermarket will capture and reuse heat produced by cooling cabinets and freezers to provide heating for the supermarket and local community through district energy, Danfoss said.
The supermarket will be connected to the Nordals Fjernvarmeværk district heating plant and will be able to supply it with surplus heat, Danfoss added.
The cooling system in the new supermarket will also run on carbon dioxide, as a natural refrigerant, which helps to reduce the overall climate impact.
Kristian Strand, President, Refrigeration & A/C Controls, Danfoss Climate Solutions, said: “The origins of this project go back a long time, but the new energy-efficient Smart Store supermarket that we are starting to build today has only grown in relevance.
The goal of the project is to show how easy and profitable it is to decarbonise our economy and ensure reliable and sustainable energy use. Heating and cooling are the largest energy consumers in supermarkets. The solutions we are building here today represent the core of Danfoss solutions and will showcase how we can approach zero-energy use in food retail, together.”
According to Danfoss, the site will also serve as an Application Development Centre, where the company will work together with partners to co-develop new technologies and explore interfaces in the energy system surrounding energy storage.
Jürgen Fischer, President, Danfoss Climate Solutions, said: “The supermarket will be the focal point for a new part of our campus, where all buildings will be energy-efficient and meet special sustainability requirements. Our aim is to boost the green transition with concrete evidence of how far we can go with energy efficiency. We want to demonstrate to customers and partners how energy-saving solutions work in real life. We want to show the greenest energy is the energy we don’t use or reuse.”
According to Danfoss, BALS, Brugsen for Als and Sundeved, Denmark’s largest independent supermarket association, will rent the building from the company and install a COOP 365 discount supermarket. BALS, which works together with COOP, has a total of 13 stores in the area around Sønderborg in Denmark and, since 2015, has consistently reduced the consumption of energy in its stores. So far, it has cut 44% of its total CO2 emissions, Danfoss said, adding that it was, therefore, a natural next step that BALS became a partner in the project.
Danfoss said it is establishing a showroom in a part of the supermarket building, where all installations are visible to visitors and customers. It said visitors will be able to experience its solutions for heating and cooling, such as CO2 as a refrigerant, heat recovery and the interaction between installations, once the building is in operation.
Valmet to deliver multi-fuel boiler plant to Veolia
ESPOO, Finland, 2 May 2021: Valmet will deliver a multi-fuel boiler plant to Veolia Energie ČR, in Prerov, in the Czech Republic, the Finland-headquartered company said through a Press release. The new boiler will replace an old coal-fired unit and strengthen Veolia’s strategy to move toward more environmentally friendly production of district heat and electricity, Valmet added. Valmet said the order was included in its orders received in the first quarter of 2021. Typically, the value of this kind of order is EUR 35-40 million, it said. The boiler plant will be taken over by the customer in January 2023, it added.
“We chose Valmet based on the criteria of public procurement, in other words, on the combination of price and operational costs for 15 years,” says Jaromir Novak, Head of Technical Department, Veolia Energie ČR. “Valmet has a high number of running references and long experience with boilers. That is why we trust Valmet and already cherish our future relationship.”
Jari Niemelä, Director, Boilers and Gasifiers, Valmet, said: “This is yet another great example of how Valmet can support decarbonization in the energy sector. We will even reuse the existing boiler house to help reduce not only CO2 emissions from energy production but also from constructing the power plant. With flexible use of biomass and waste in all possible mixtures, the plant is fit for the challenging energy transition.”
Valmet said its delivery scope includes a 40 MWth Valmet BFB Boiler, utilising bubbling fluidised bed combustion technology. The boiler steam production is 52 t/h at 4.2 MPa(g) and 420 degrees C, it said. The multifuel boiler is designed to run from 0 to 100% on refuse-derived fuel (RDF) and/or biomass, it added.
Additionally, Valmet said, the delivery includes a flue gas cleaning system, refurbishment of an existing steel structure and its modification, electrification and instrumentation as well as an upgrade of an existing automation system.
Valmet to supply a boiler plant for district heat production
ESPOO, Finland, 21 January 2021: Valmet will supply a boiler plant for district heat production to Seinäjoen Energia Oy’s Kapernaum heat plant in Seinäjoki, Finland, the company said through a Press release. The new boiler will enable the plant to increase the use of renewable fuels in its district heat production, it added.
Owned by the city of Seinäjoki, Seinäjoen Energia provides its customers with services in electricity, district heating and water supply, Valmet said. The company has approximately 4,500 district heat customers with an annual heat need of over 500 GWh, Valmet added.
The order is included in Valmet’s orders, received in the fourth quarter 2020, the company said, adding that the boiler plant will be handed over to the customer in autumn 2022.
Vesa Hätilä, Managing Director, Seinäjoen Energia, said: “We are pleased to start this project. It is a significant step forward in producing cleaner district heat. We will be able to ensure reliable and competitively priced heat for our customers in the future, too.”
Added Kai Janhunen, Vice President, Energy Business Unit, Valmet: “This project features notable environmental values and a great significance for the district heat produced in Seinäjoki. Valmet’s delivery combines strong technical knowhow with high-quality and swift project management. We appreciate Seinäjoen Energia’s trust in Valmet.”
Valmet said it will build the new boiler plant from the foundation upwards all the way from the fuel feed silo to the stack. The core of the delivery is Valmet BFB Boiler, which utilises bubbling fluidised bed technology and runs on a wide range of biomasses. Additionally, Valmet’s delivery includes an electrostatic precipitator, a flue gas condensation unit and a Valmet DNA Automation System for the entire plant, among others.
The fuel capacity of the boiler plant, Valmet said, is 49.5 megawatts (MW). Its maximal district heat capacity, it added, is 56.5 MWth with the flue gas condensation unit.
‘The UAE leadership has a view of the future – and it is not just tomorrow’
Congratulations on your appointment as Denmark’s Climate Ambassador. Could you speak on the potential areas of cooperation between the UAE and Denmark?
I think it’s remarkable the far-sighted leadership the UAE has taken as an oil- and gas-producing country. The leaders have a view of the future – and the future that is not just tomorrow, not just five or 10 years, but they are thinking ahead to 20 or 50 years from now.
We are talking about the major transformation of energy systems. The largest solar farms in the world are in the UAE, and a lot of investment is being done in this area. The country is taking energy efficiency in buildings seriously and addressing the challenge of having had, years ago, the highest carbon footprint per inhabitant.
In that sense, cooperation between the UAE and Denmark on energy and other topics related to food and maritime issues makes imminent sense. We are the country in the EU with the largest oil -production. We have oil and gas in the North Sea. But we are slowly ending our exploration of that oil and gas, and in December 2020, the Danish Parliament decided to end fossil extraction in the North Sea by 2050 with a plan for the just transition of impacted workers and a conversion of the oil and gas fields to Carbon Capture Utilization and Storage (CCUS)].
There is also a huge market for renewable energy, globally, as this transformation [can be seen] worldwide. In Denmark, we are building better and taller wind farms and offshore wind farms, including over the next two years in two new energy islands. As a result, there has been global interest surrounding Danish windfarm operators and wind constructors, many of whom are now in demand in a number of countries such as the US, Korea and Australia.
Could you speak more about the competitive advantage that countries such as the UAE can have from specialising in sustainable cooling solutions, both in terms of developing the expertise within the country and in terms of pioneering solutions? Do you see this to be a growing market?
The world is undergoing an energy transformation, and the UAE is also very well positioned to be part of it and, in some instances, to lead this transformation. As such, a partnership with a country like Denmark makes great sense.
When it comes to the development of cities, it’s clear that if you look at trends as a whole, [the population] is moving from the countryside to cities at an increased rate. I think the latest figures from UN Habitat and other global organisations is that almost half of the human population lives in cities. We have been going from 30-40% of the population to half, and the trajectory is pointing towards a world where most of the people are in cities.
There have been large movements in the Global South. In China, you have more than 70 cities with more than one million inhabitants, and many are newly constructed with poor quality of buildings that need to be retrofitted and rebuilt. In India, you have a growing middle-class population, and this has led to growth of new buildings in new cities or more modern buildings in new parts of the city. The same trend can be seen in the Gulf region. For a very long time, Dubai was home to most of the cranes in the world. In Africa, large cities that are already big, continue to grow. In Indonesia, we see a population in the process of moving Jakarta to a new island, because it is sinking.
Basically, in many places, the built-environment is not a done deal. We are at the beginning, not at the end. It’s only in older industrial countries in the West that the city structure is permanent. I would think the opportunities for both new buildings and retrofitting are very large, especially in warmer climates, where expertise is needed in challenging environments.
For us, in Denmark, it’s more about reverse engineering our experience with energy efficiency and insulation, and usinge and applying them in the UAE. Also, there would be solutions we need to develop from scratch, based on the circumstances and the physical environment.
It’s clear that cooling also has some attributes different from heating. [In Denmark], some companies are experimenting with district cooling, but most are district heating, with a lot of combined power and heat plants. Also, some of them are doing this with garbage waste disposal and heat and power. With the more recent climate law, because of the move towards circular economy, we are now looking at recycling and reusing our waste rather than incinerating it.
What can further drive the development of expertise and solutions in the sustainability arena in a country?
A combination of energy pricing and embedding efficiency in building codes and regulation by central and local governments are key here. The building owner and operator might not be interested in building more efficiently because of the perceived cost, and they will try to defer the cost onto the tenants. That means rent goes up, bills go up, and they are not too happy either. That’s always a question for the less well off, that’s also the question of the fair and equitable distribution of the cost and benefit, [[when it comes to implementing sustainable solutions.].
In Denmark, people have been investing in energy efficiency because of energy cost and due to strict regulation since the 1970’s. Because of the cost of energy, there are huge paybacks at a shorter time.
In what ways can the public sector in the GCC region incentivise sustainability initiatives in the built-environment, both in terms of introducing retrofit targets and also ensuring new buildings adhere to higher energy- efficiency goals?
For one, I would say that educating the general public is extremely important, in terms of the cost, economy, sustainability and potential social benefits.
The very practical education of engineers and economists, integrating energy efficiency into curricula in the built-environment, so that you have your own skilled engineers and technicians ¨to operate systems, do the buildings and learn from it. It is a mentality and way of thinking. We have done it for the last 50 or more years; we didn’t do it before that. It took us a long time and heavy regulation, strong incentives and a lot of private discussion among government and private sector and institutions of higher education to get that sector to operate in an efficient and integrated way. I would encourage public policy makers to think through different dimensions of how to establish a cluster of knowledge and expertise. The young students of today will be the leaders of tomorrow, and they have to make it work 10-15 years down the road.
Climate change and the larger picture of finances
Q&A: James Brainard, Mayor of Carmel, Indiana, United States
We have succeeded admirably in our fight against the depletion of the ozone layer through collective effort, through a cohesive, consensus-based approach of finding economically and technically sound alternatives to ozone-depleting refrigerants. How much confidence do you take from what has been a marvellous example of social cooperation?
We did the summit in the form of the Montreal Protocol over concerns of huge spike in cancer deaths, so it was a great example of world leaders coming together to study a problem, devise a solution and then go back to their countries to fix the problem. It shows diplomacy and recognition of common challenges can be good.
In the same way, could we not find a financially feasible, well-structured long-term plan to curb the widespread misuse of energy and general profligacy through steady and substantial investment in the infrastructure needed to achieve the goal?
You have identified the problem in the question, and we have to find the means of accomplishing this. We have to look at the larger picture of finances – the health impact of pollution; the cost of famines; the cost of relocation, if we have a rise in sea level, leading to the displacement of people from major cities; and the cost of possible conflicts arising out of this. But more specifically, we need to recognize many jobs are dependent on the fossil fuel industry. So, we can make those changes, but we have to recognize that we need to look out for investment of industry, we still need to fly airplanes. But, we have a saying in the US, ‘low- hanging fruit’. So, there are many easy things we can do to clean the environment and reduce fossil fuel use, and those are what we can focus on with recognising that we have to protect people’s jobs in the fossil fuel industry and that many are invested in the fossil fuel industry.
Would an approach of self-financing the fight against global warming by developing an energy budget in every city, town, state and country across the world be a possible way out, as propounded by George Berbari, the CEO of DC Pro Engineering? I am referring to a structured, long-term carrot-and-stick approach, where individuals and organisations occupying residential and commercial buildings could be rewarded for being energy efficient and penalised for being inefficient, with the penalty being slightly higher than the reward to create a positive budget, a surplus, which could be used for giving rebates to homeowners for improving insulation, glazing, etc., for developing infrastructure to lower primary energy use, for building thermal energy networks, even District Energy schemes… anything that would effectively fight climate change.
I think it would help. The colloquial shotgun approach, where we undertake to do a lot of small things. I think your idea of financial incentives and disincentives is good; and tied to that what needs to happen is disincentives need to increase over time and incentives need to go up and come down. It is certainly a system we need today. You could still pass laws, where each year, the incentives and disincentives change, to encourage disincentives to go up and incentives to go away. The tax system is also there. Or, it could be a separate tax, a carbon tax, and it has been discussed here since the late 1980s.
Economists believe such an approach to conserving primary energy is feasible, but democratically elected local and federal government leaders and local mayors have limited terms and, generally speaking, give priority to short-term problems, the solving of which gives them immediate political benefits, as opposed to decades-long and daunting task of curbing energy use through a financial mechanism and other initiatives, which might also be viewed by the city’s inhabitants that make the electorate, as adding to existing costs and impairing their personal and corporate competitiveness. In your case, you are one of the longest-serving mayors in the state, having been in office since 1996 over seven consecutive terms. Did that give you a canvas to paint a long-term vision? How effective was the approach? Did it help you shape regulation and enforcement at a city level? Were you able to raise greater awareness on the human impact on climate change and bring about a consensus-based change in energy use behaviour in Carmel?
We are a suburb of Indianapolis, which has a population of two million people. We are 100,000 people in Carmel. Now, places like Dubai and Doha require automobiles, owing to the urban sprawl. Generally, we need the automobile to go anywhere. We have looked at the problem and have a series of PPPs, where one can live, work, go to restaurant and engage in recreational activities without having to get into an automobile and, as a result, lower the consumption of fuel.
The average American spends two hours a day in automobiles, but in Carmel, businesses, houses, schools are all here. We have adopted land use development differently, so people can live, work and go to a restaurant all in the same area, and we tried to design our downtown not for automobiles, and it has cut down fuel use. In Carmel, it is 15 minutes to half an hour of automobile use per person, so it is much, much less [than the national average].
We have a legal structure in the state of Indiana that makes decisions on building codes, and they have done less than what I would like to see, but we have contract to have a much more efficient build. We have the example of the Energy Center in Carmel. We have cold winters and hot summers in Carmel, and we are using energy all year long to either heat or cool our buildings. And if you have an individual heating or cooling system, it starts and stops and is energy inefficient. And so, we have developed the Energy Center in the city, and it uses 50% less energy. And we would like to see this being applied across the city.
If energy is scarce and its excessive use damaging to the environment, should people be allowed to consume as much as they want to, as long as they are paying for it? Should affordability be a sole factor? Could we change that mindset and, at the same time, take care not to infringe on personal freedom and quality of life?
I have thought about it, and I believe in a capitalistic and free market approach. And there is a way to fix it, which is you pay USD 10, say, for 100 units of use, USD 15 for the next 100 units, and USD 20 for the next 100 units. And so the more you use, the higher the price. And it is a good system, because it penalizes the people to use it, and at the same time, they have the freedom to use it. In the case of steel production, maybe that may be very important for the economy and jobs, and so there should be a different model. You have to look at the situation where we can improve the environment, decrease carbon and increase quality of life.
Have you established a carbon neutrality goal for Carmel, like Copenhagen, for instance, where we are seeing a consensus-based approach involving all political parties, underpinned by the thought process that environmental action needs to be bipartisan in nature? Or are the political dynamics different in the United States?
It’s a good question. Our city is mainly Republican, and is fiscally and economically conservative. Some years ago, a seven-member council introduced a carbon neutrality goal, which is not mandated, however. We know we will get there, because the technology is there. It is not time bound. It is a legislative body that passed a law that laid out a carbon neutrality goal.
We have been measuring progress in reducing carbon. Every year, we are measuring how much energy the city is using on a per capita basis, because the city is growing. I don’t know if we have done enough yet, but we are making progress. I firmly believe technology will save us.
The fight against climate change needs to be a non-partisan effort within cities, states and nations. What we have seen is a vastly polarising view within the United States. With Joe Biden set to take the reins, how soon can we expect to see the United States aligning itself in a more profound manner to the Paris Agreement?
I am a Republican, and my undergraduate degree was in history, so I tend to think not today but historically. At the turn of the century, Ted Roosevelt, a Republican, set aside millions of acres in the US for the National Parks system. And President Eisenhower in 1952 established the Arctic Reserve in Alaska, and he was Republican, as well. And President Nixon was the one who set up the federal EPA. Republicans signed a law that amended our Clean Water Act. They passed a whole series of environmental laws. President Reagan led on the Montreal Protocol for the ozone protection initiative. George HW Bush and George Bush came from a state that produces a lot of oil, and yet they established a system of hundreds of windmills. Over 120 years, Republicans and Democrats have come together in a non-partisan manner. And they will come back; this anomaly has been only for a sort period of time. Clean air and water are non-partisan issues. Disagreement will come only in terms of jobs.
On December 11, 2020, the United States observed a new daily death record of 3,055 individuals, more than the number of people who died in Pearl Harbour or the September 11 attacks on the twin towers in New York City. The coronavirus cases have risen sharply in Carmel, as they have elsewhere in Indiana and across the country. What measures have you taken in Carmel to safeguard residents through better indoor air quality (IAQ), with science advocating more fresh air changes and maintaining Relative Humidity between 40% and 60% in buildings?
I think one good thing that has come from the pandemic is recognition of IAQ being important, and there are great many entrepreneurs in the US selling systems that clean the air. Our City Hall operates a new system that every few minutes recycles the air and filters and cleans the air in the building; and it is energy efficient. And building owners throughout the US are adopting this. I see this as a positive thing that has emerged.
I have put a taskforce in Carmel. We also have generated messages through emails and print newsletters and social media. We have used an entire gamut of ways to talk to people, not just about IAQ but also about things to do to handle the pandemic in a better way. Our city had done a good job till the first week of October, testing and quarantining people. It worked through summer, but when people came indoors when the temperatures fell, it went bad. We had our first set of vaccinations, yesterday (the interview with Mayor Brainard took place on December 15), so we hope to be in good shape by March or April 2021.
There are those that are saying building industry stakeholders simply need to reverse the polarity on their thinking when it comes to budgeting for indoor air quality and that we need to raise buildings fit for purpose.
Yes, it’s a good point. Energy for buildings is important, but I think IAQ is something that would work very well. We have tax incentive to make buildings more energy efficient, and over time if building owners do not take action, a penalty would start; and simultaneously, there will be a reduction in taxes for people who make more energy-efficient buildings. And that puts the burden away from the average taxpayer. Yes, I do believe in an incentive and disincentive system for establishing good IAQ.
Islington and Clapham
As we bid goodbye to 2020 and gingerly step into 2021, the feeling is not of relief, because the virus is still on the prowl. It must be added, though, that we have reached an inflexion point with the early promise being shown by some of the vaccines that have been deployed.
Now, amidst the carnage of 2020, we have been witness to heartwarming instances of human endeavour – of the medical fraternity putting their lives at risk to save others, of boffins hard at work harnessing the power of science and engineering to provide relief to not only healthcare workers but also numerous other sectors.
Away from the COVID scene, there are other instances that have stood out. Like the Bunhill Heat and Power Network project, in central London, which uses waste heat from the London Underground network to supply heat and hot water to nearly 1,500 homes and other facilities in the Borough of Islington, in a bid to lower indirect carbon emissions and to achieve carbon neutrality by 2030. Human ingenuity repurposed the former City Road London Underground station into an underground air extraction system. It draws warm air from the tunnels, still in use by the London Underground’s Northern Line.
Not only will the project reportedly lower indirect emissions but also cut heating costs by 10%, benefitting the residents connected to the network – a case of district energy providing succour to tenants by passing on the savings.
What is even more heartwarming, according to the company that supplied the technology to the project (see story on page XX) is that it can be replicated in underground networks the world over.
As if by coincidence, the subterranean labyrinthine depths of London constitute the theatre for yet another instance of human ingenuity and resourcefulness. Growing Underground is a farming enterprise that is using long-forgotten World War 2 tunnels used as shelter during air raids conducted by the Luftwaffe. About 100 feet beneath London’s Clapham, growers working for the enterprise are busy harvesting micro-greens using hydroponic technology, which uses 70% less water, when compared to traditional farming practices. The produce is pesticide-free and provides an opportunity to Londoners to eat fresh and without the guilt from knowledge that the greens on their plate are the result of burning copious volumes of climate-threatening fossil fuels in transporting them to their doorstep. The project is redefining food supply chains for the better and lowering food wastage by increasing shelf life.
Such examples as the Islington district energy scheme and Growing Underground serve as inspiration for us to consider abandoning some of the hackneyed approaches that are not taking us far in our quest for a better planet. They are about courage and speak of a certain frontier spirit that we ought to consider embracing.
