District heating via solar-powered heat pump using industrial waste heat
The Fraunhofer Institute for Solar Energy Systems is assessing how a solar-powered heat pump system that uses waste heat from a distillery at a low-temperature level could be used to provide district heating. Waste heat is injected into an ice storage tank, to which heat pumps are connected on the source side.
The world’s largest seawater heat pump based on CO2 as refrigerant
Swiss-headquartered technology corporation ABB is supplying integrated electrical infrastructure for the construction of a 50 MW seawater heat pump in Denmark. The heat pump technology will be provided by German specialist MAN Energy Solutions.
Heat pump control strategy for solar assisted district heating
Researchers in Spain have proposed two control strategies for the integration of heat pumps in district heating systems assisted by solar thermal collectors. Their technical-economic analysis shows that the proposed combination can reduce reliance on gas while also reducing costs.
Photovoltaics, heat pumps to rescue failed geothermal project in Poland
The Polish government is supporting a hybrid renewable energy project based on a deep-borehole heat exchanger (DBHE) whose heat pumps are powered by photovoltaics. The heat generated by the facility will be used for district heating.
Pilot project to couple wind and solar with heat pumps in Germany
The Institute for Solar Energy Research Hamelin (ISFH) is testing if renewables can cover 80% of electricity and heating demand combined in some town districts in southern Germany.
Ten-year renewal of Estonia’s renewables support program
New €450 million incentive regime needed to be approved under EU state aid rules.
What is the UK government’s problem with solar?
You’ll need to pay close attention to find the few mentions of solar in the long-awaited White Paper issued by the government to outline how it plans to hit net zero by mid century.
Photovoltaic-thermal district heating networks are feasible
A group of scientists and companies in the Netherlands has tested a PVT heating concept in a green district and has found that the proposed design, which is also based on underground storage and the use of heat pumps, is technically and economically feasible.
Power-to-heat for district heating may drive wind and solar
Researchers say the technology could help drive clean energy deployment in countries with limited grids or in isolated, coal-based energy systems. According to their model, Kosovo could see a strong increase in wind and PV capacity if power-to-heat is coupled with thermal energy storage for fixed-capacity district heating.
