An industrial-scale seawater-based warmth pump from MAN Energy Solutions is now supplying zero emissions warmth for the district heating system operated by DIN Forsyning in Esbjerg, Denmark. The Mega warmth pump will provide roughly 280,000 MWh of warmth per yr to native district heating networks. The system makes use of carbon dioxide as the warmth change medium for the warmth pump system, which has a 70 MW whole heating capability and operates in tandem with a 60 MW wooden chip boiler that burns sustainably sourced wooden chips and a 40 MW electrical boiler that can be used for peak and backup load duties. It’s the first of many bigger industrial-scale warmth pumps.

The Mega industrial warmth pump makes use of renewable vitality from regional wind farms and seawater from the North Sea as a warmth supply, delivering warmth to 25,000 households and lowering carbon dioxide emissions by 120,000 tons yearly. The warmth pump set up aligns with town of Esbjerg’s intention to achieve local weather neutrality by 2030. The warmth for the district heating system beforehand got here from a coal-fired facility that has now been decommissioned.

“This is a significant milestone that we have anticipated for a long time,” mentioned Helle Damm-Henrichsen, the managing director of DIN Forsyning. “From now on, all our customers in Varde and Esbjerg will benefit from district heating directly sourced fron the North Sea. This achievement is not only transformative for DIN Forsyning but also a step forward for the climate. While we may be in western Jutland, I believe it’s fair to call this a world premiere. The world’s largest CO2-based seawater heat pump is now producing heat.”

The MAN Vitality warmth pump system helps the intermittent energy equipped by photo voltaic and wind installations so it could possibly react shortly to variations within the quantity of energy accessible from {the electrical} grid. The system could be switched on and off a number of instances every day to match the vitality provide from the grid. DIN Forsyning leverages the pump’s unhazardous and environmentally protected carbon dioxide to make sure clear operation close to the Wadden Sea, which is a UNESCO World Heritage web site.

“I’m proud that our mega heat pump is now providing climate-neutral heat to the people of Esbjerg and Varde,” mentioned Dr. Uwe Lauber, CEO of MAN Vitality Options. “Esbjerg demonstrates how urban heating systems can be reshaped by harnessing renewable energy sources. Utilizing industrial-scale heat pumps to deliver sustainable heating is not just a technological achievement but a blueprint for other cities worldwide as they transition to greener energy systems.”

The MAN Vitality Mega warmth pump makes use of electrical energy to boost low-temperature thermal vitality to usable ranges effectively. For each MWh {of electrical} vitality consumed, about three MWh of thermal vitality is generated. The warmth pump for the DIN Forsyning district heating facility is provided with two oil-free, hermetically sealed HOFIM compressors that use high-speed motors and energetic magnetic bearings to reduce upkeep necessities. These models and auxiliary techniques can be built-in with distant monitoring, knowledge analytics, and diagnostics.

Industrial Warmth Pumps For Course of Warmth

The MAN Vitality Mega warmth pump is optimized for district heating, however warmth pumps are additionally getting used to produce the method warmth that’s important to manufacturing of many merchandise. Some warmth is required to cook dinner meals and pasteurize milk. Larger temperatures are wanted to dry the paint on vehicles or make typical lithium batteries. Right now, about 95% of course of warmth comes from burning fossil fuels and accounts for 8% of worldwide carbon emissions. A warmth pump is able to supplying warmth for manufacturing as much as 200º C (392º F), so why not use warmth pumps to produce course of warmth for industrial and business purposes?

That’s an awesome query. In keeping with ETH Zurichone of many world’s preeminent analysis establishments, in a conventional heat pumpthe achievable temperature and temperature profiles are largely decided by the selection of refrigerant. All the warmth pump parts — from the evaporator and compressor to the condenser and growth valve — are tailor-made to the traits of the refrigerant used. If a manufacturing unit requires warmth at completely different temperatures for a number of purposes, this could solely be achieved by utilizing a number of warmth pumps, every with a unique refrigerant. That is each expensive and inconvenient, which is why utilizing a warmth pump has made little headway within the industrial sector.

André Bardow, Professor of Vitality and Course of Techniques Engineering at ETH Zurich, believes his group has give you a greater resolution: “Instead of a single refrigerant, we use a blend. This allows a heat pump to use different heat sources and generate different temperature profiles.” The composition of the refrigerant mix could be various to cater to completely different purposes, which is a key profit for corporations. As an alternative of getting to revamp your complete warmth pump at any time when they want a unique temperature, they will merely modify the combination, which is far less complicated and cheaper.

The combination itself consists of a conventional refrigerant and one additional element. The temperature profile of the warmth pump is dictated by the ratio of those two components. “In principle, you can have any number of different profiles for industrial processes, as long as the temperatures don’t exceed 200 degrees. That’s the major advantage our technology offers,” Bardow says.

To establish appropriate parts for the refrigerant mix, the researchers developed a pc mannequin that simulates the warmth pump circuit with completely different variants of refrigerant combination. “We extended the existing thermodynamic models for heat pumps by integrating the heat pump components as well as the composition of the mixture into the optimization process,” says Dennis Roskosch, senior scientist within the analysis group headed by André Bardow. The researchers’ mannequin analyzed over 200 million recognized artificial molecules to simulate a mix of two molecules that provides essentially the most environment friendly warmth pump efficiency.

Warmth Pumps Achieve Recognition

What’s it about heat pumps that will get individuals excited? Fairly merely, it’s effectivity. A warmth pump produces extra warmth per unit of vitality than typical warmth sources. That interprets into decrease prices, which is what will get the eye of shoppers. Numerous individuals pay lip service to the concept of decreasing carbon emissions, however displaying somebody the best way to lower their vitality payments by 40% or extra is what actually will get their consideration. Warmth pump expertise is maturing quickly, providing individuals residential warmth pumps that function simply superb in freezing temperatures — one thing they couldn’t do 5 years in the past.

Corporations like MAN Vitality at the moment are providing business clients industrial heat pumps just like the one in Esbjerg, Denmark, that supply the benefits of warmth pumps on a a lot bigger scale. Over the subsequent decade, extra superior warmth pumps will match the wants of extra residential and business clients so we will burn fewer fossil fuels to warmth our properties. Excellent news for the setting, however even higher information for individuals who need extra warmth for much less cash.
