Karlsruher Institut für Technologie (KIT) researchers have now found that low-temperature aquifer thermal energy storage is of great potential in Germany. This potential is expected to grow in future due to climate change. Aquifer thermal energy storage systems can largely contribute to climate-friendly heating and cooling of buildings: Heated water is stored in the underground […]

A University of Houston professor is reporting on a new type of solar energy harvesting system called thermophotovoltaics (STPV) that breaks the efficiency record of all existing technologies. And no less important, it clears the way to use solar power 24/7. Photovoltaic cells which convert sunlight directly into energy have made much progress. Yet with […]

A Hokkaido University team has found a thermoelectric metal oxide film with a thermoelectric figure of merit of ~0.55 at 600° C, opening new avenues towards the widespread use of thermoelectric converters. The team led by Professor Hiromichi Ohta at the Research Institute for Electronic Science at Hokkaido University synthesized a barium cobalt oxide thermoelectric […]

Chalmers University of Technology scientists have pioneered a recycling method that is inspired by the natural carbon cycle and could eliminate the climate impact of plastic materials. Can replace fossil raw materials Henrik Thunman, Professor of Energy Technology at Chalmers University of Technology and one of the authors of the study published in the Journal […]

American Institute of Physics researchers have constructed a photovoltaic cell that works both day and night by making use of the heat leaking from Earth back into space. At night, solar cells radiate and lose heat to the sky, reaching temperatures a few degrees below the ambient air. The device under development uses a thermoelectric […]
