waste heat

UK startup develops high-temperature heat pump that produces steam from waste heat

FutraHeat has designed a heat pump that can operate at reduced speeds without oil, recover waste heat from as low as 70 C, and deliver high-grade heat up to 150 C. The electrically powered heat pump utilizes waste heat from all sorts of industrial processes, including drying, distillation, and brewing.

Recovering waste heat from solar cells via a thermoelectric generator

Scientists in Italy have created a hybrid thermoelectric photovoltaic (HTEPV) system based on a thermoelectric generator and a wide-gap perovskite solar cell. The device is able to recover waste heat from the PV unit and produce additional power. According to its creators, this configuration needs large gap cells as these are less sensitive to temperature in terms of efficiency

The Hydrogen Stream: Plans for $75bn, 50 GW green energy hub in Western Australia

Plus, as the European Commission prepares to present its ‘Fit for 55’ climate change package tomorrow, European companies are continuing to develop hydrogen plans, including Shell in Norway and Siemens in Germany.

Industrial green hydrogen could become a global commodity but local production is needed for transport uses

Long distance, point-to-point transport of green hydrogen for industrial use can harness the cheap solar electricity available in some parts of the world but distributing the energy-storage gas to individual refueling stations, for vehicle fuel cell use, will likely have to depend on production nearby.

Harnessing heat for 80% theoretical efficiency

Scientists at Rice University in Texas have developed a device which converts heat into light by squeezing it into a smaller bandgap. The ‘hyperbolic thermal emitter’ could be combined with a PV system to convert energy otherwise wasted as heat – a development the researchers say could drastically increase efficiency.

Waste heat is not cool, say US scientists

Engineers at the University of Utah have developed a tiny device which they say could increase the performance of PV panels and other electronic devices by converting energy lost as heat back into electricity.
