High-performance sodium and potassium ion batteries via new carbon electrode materials
Researchers in the UK have developed a novel controllable unidirectional ice-templating strategy to fabricate new carbon electrode materials which can boost the performances of sodium and potassium-ion batteries.
Solar-plus-storage for aquaculture aeration
Recent research from Thailand has shown that solar-plus-storage on floating platforms could be the cheapest option to power energy-intensive aeration systems in aquaculture projects. The battery accounts for around 54% of the capital costs, which is why system sizing would be key for economic viability.
Vattenfall launches high-temperature heat pump solution to replace gas boilers
Developed in partnership with Dutch heating specialist Feenstra, the all-electric heat pump solution will initially be available in the Netherlands. The system’s buffer works as a heat battery that is used to provide heat to radiators and generate hot tap water.
New tech to reduce mechanical stress in floating PV arrays
French start-up HelioRec has developed a new floater that can contain water to add more weight and increase its stability on the water. According to its creators, the new product can be 3.5 times more stable than conventional blow-molded floaters.
Chinese fish pond hosts 550 MW solar farm
Built by the Chint Group, the project is currently the largest in China combining PV power generation and fish farming. It is located in Wenzhou, a city with a subtropical maritime monsoon climate in China’s Zhejiang province.
US startup debuts energy storage system
Franklin Whole Home has developed an integrated battery and control system with artificial intelligence. It is inverter-agnostic, can be used to charge electric-vehicle batteries, and turns homes into microgrids when utility services are down.
Electrolyzer tech to produce hydrogen from seawater
With a new start-up and a consortium in the Netherlands, German automotive supplier Schaeffler wants to significantly reduce the costs of green hydrogen.
Lowering solar module temperatures with radiative cooling, heat pipes
Chinese scientists have developed a hybrid cooling technique to reduce module temperatures by up to 12.86 C and increase power yields by 7.25%. Their system features a PV module and a separate RC module, integrated with a flat plate heat pipe in between.
Large-scale PV could improve voltage of weak grids in Nigeria
Researchers have discovered that large-scale PV arrays could enhance the voltage stability of northern Nigeria’s electricity grid.
Solar-powered hydrogen for domestic applications via building-integrated transparent platform
An international research group has created a closed-loop, transparent energy platform based on PV power generation and hydrogen production from photo-electrochemical cells. The system is claimed to supply power without interruption and to be transparent enough to be integrated into buildings.
