heat pumps

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.

Household heat pumps, EV chargers and rooftop solar panels will be able to earn their owners benefits in return for helping to balance grid networks struggling to accommodate new solar and wind power generation.

The Dutch association of national-regional electricity and gas network operators, Netbeheer Nederland, is leading a plan to deploy up to 2 million hybrid heat pumps by 2030. The plan should be supported by a subsidy scheme by the government and enable the installation of at least 100,000 heat pumps per year from 2024.

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.

Danish gas transmission system operator Evida will exempt homeowners and individuals that want to abandon gas and choose renewable energy for heating from paying the grid disconnection fee. The scheme will be run on a first-come, first-served basis.

Researchers in Spain have compiled a list of key performance indicators intended at evaluating not only the quality of a heat pump or a PV generator; but also the quality of their integration. pv magazine spoke to research co-author Celena Lorenzo about the potential and challenges of this combination. According to her, heat pumps powered by PV alone are efficient enough for both cooling and heating.

Dutch transmission system operator Tennet, which also serves Germany, is planning to create flexible electricity demand and reduce grid congestion by promoting the use of smarter heating systems and heat pumps that can also be powered by solar and wind energy. According to its experts, intelligent control of heat pumps may result in the creation of between 0.5 and 1 GW of temporary grid flexibility by 2030.

Solarpower Europe has called on member states to put solar and battery storage front and center when it comes to drawing up the Recovery and Resilience plans needed to secure a slice of the bloc’s proposed €672.5 billion post-Covid stimulus package.

Dutch company Triple Solar has launched a photovoltaic thermal solar panel for residential buildings which can be connected to a brine or water heat pump. The manufacturer says the heating system based on the panel is an ideal alternative to less efficient air and water heat pumps and more expensive geothermal systems. The grid-connected PV system can export excess power under net metering programs.

With its sonnenVPP, German battery company Sonnen wants to improve the efficiency of virtual power plants which it says can offer primary balancing energy from houses with solar and storage and can operate up to 90% more cost-effectively.
