Germany’s new rebate program for residential heat pumps has come into effect
A set of amendments to Germany’s law that offer a rebate program for sustainable heating has come into effect on January 1st. The new rules grant rebates of up to 40% to help homeowners to buy and install heat pumps.
Hanwha Q Cells launches residential solar-storage-heat pump solution in Europe
Hanwha Q Cells has combined its solar panels and batteries with Samsung’s heat pumps. The offering includes an app that reportedly optimizes power consumption while maximizing solar power utilization.
Solar-driven multigeneration system for hydrogen, electricity, heat
An Iranian research group has developed a system that combines photovoltaic-thermal modules with organic Rankine cycle, a proton exchange membrane electrolyzer, and liquefied natural gas. The ideal system has an exergy efficiency of 16.24%, a cost rate of $4.48 per hour, and 33.32 kW of net electrical power.
Long-term, heat-based energy storage in aluminum
Nine partners from seven European countries are involved in the €3.6 million ($3.7 million) “Reveal” research project, which says buildings could be heated in the future by storing energy from PV, wind and water in aluminum.
Impact of heat pumps on Ireland’s energy system
New research from Ireland shows that electrification could lead to more efficient utilization of renewable energy and the national transmission network.
Solar-powered residential heating system based on storage heaters
Spanish heating specialist Elnur Gabarron offers a residential heating system that works with surplus solar power and storage heaters. The system can work as a backup solution, combined with existing conventional heating, or as a household’s main heating system, with minimal use of grid electricity.
Thermo-acoustic heat pump for residential applications
Dutch researchers have developed a heat pump that can be used in combination with rooftop solar generation, due to its modulating capabilities and temperature flexibility. It measures 55 cm x 55 cm x 55 cm and has an output of 6 kW.
Photovoltaic sanitary water heater from Belgium
Belgian heating specialist Wanit has developed a solar water heater that purportedly reduces the cost of domestic hot water by 85%. The PV water heater solution includes a main dual tank and a solar connector that links the tank with a rooftop PV system and residential battery.
New PV water heater from Germany
German startup Nexol has developed a photovoltaic water heating system that relies on a smart controller, with either DC and AC power. It decides autonomously if grid electricity or PV is used, with the latter always preferred.
Concentrating solar power system for building applications, usable with PV
Conceived by a German start-up, the system is claimed to achieve a 75% efficiency in converting direct radiation into heat. It may be either equipped with solar trackers or photovoltaic modules, which would both occupy the same space on the front and lateral sides of the installations.
