New fault detection techniques for air-to-air heat pumps
Portuguese researchers have compared several applied machine learning techniques to detect faults in air-to-air heat pumps in cooling mode. The results showed a high level of performance based on four metrics.
The Hydrogen Stream: Germany grants €4.6 billion to 23 green H2 projects
The German government has granted €4.6 billion ($5 billion) for 23 green hydrogen projects, while BP has revealed separate plans to develop a 100 MW green hydrogen installation in Germany.
Elastocalorics could replace heat pumps, air conditioning systems
Elastocalorics have the potential to replace current air conditioning and heating systems, offering significant energy savings when paired with technologies such as photovoltaics.
PV cell integrating molecular thermal storage tech achieves 14.9% solar utilization efficiency
Scientists in Sweden have integrated a PV device with a molecular solar thermal (MOST) energy storage system, which acts as as a solar cell optical filter and cooling agent. The proposed combination achieves a 0.2% higher PV efficiency and solar storage efficiency of 2.3%.
German researchers develop ‘communicative’ PV panels
A German research team is conducting practical tests to see how solar modules with integrated radio technology can be linked to form an overall network. The “communicative” panels should represent a simple and cost-effective solution for monitoring and controlling small-scale photovoltaic systems.
UK energy retailers add heat pump tariffs
Time-of-use and type-of-use tariffs for heat pump customers launched to support technology adoption in market where gas heating remains competitive on price.
