The case for residential solar sharing
Technische Universität München researchers have run a series of tests to investigate the growing share of rooftop PV in Germany. They found that the sale and purchase of electricity between households could reduce consumption peaks and prevent grid bottlenecks.
IEA says global heat pump installations to hit 600 million by 2030
The International Energy Agency (IEA) says that the deployment of 600 million heat pumps by 2030 could cover 20% of the annual heating requirements of buildings throughout the world.
PV-powered direct air electrolysis module to produce hydrogen from moisture in air
Scientists in Australia have developed a new way to produce hydrogen using water from the atmosphere. They claim their new module can ensure stable performance and provide green hydrogen for remote areas.
Meritsun unveils 15 kWh lithium-ion battery for residential applications
Chinese battery provider Meritsun says its new 48 V battery has a storage capacity of 15 kWh and a rated capacity of 300 Ah.
PV-driven rechargeable control module for ‘cyborg cockroaches’
Japanese researchers have built ultra-soft PV devices and ultra-thin electronics that can be placed on the curved abdomens of cockroaches without affecting their mobility. The system can be used to monitor hazardous areas, or for urban search-and-rescue operations.
The Hydrogen Stream: Condensed hydrogen on smooth surfaces can sharply exceed liquid hydrogen density
A German-US research team has shown that hydrogen condenses on smooth surfaces at a very low temperature, forming a super-dense monolayer that reduces the volume to just 5 liters per kilogram of H2. Dutch researchers, meanwhile, have published a new study on hydrogen storage in porous rocks, and Itochu said it is moving forward with hydrogen plans in Japan and South Africa.
Storing renewables with seawater batteries
Scientists in Germany have studied how seawater batteries could be used for renewables storage and desalination.
Australian pumped hydro storage project secures funding
The government of New South Wales, Australia, has announced funding for five pumped hydro schemes spread across the state, as it looks to deliver large-scale energy storage and firming capacity.
Wall-mountable lithium battery inverter from India
India’s Mecwin has unveiled compact, wall-mountable lithium battery inverters with 1,100 VA and 2,100 VA ratings. The 1,100 VA devices measure 455 mm x 530 mm x 235 mm and weigh 23 kg. The built-in batteries can be charged with grid power and solar electricity.
Zinc8 to manufacture its first zinc-air batteries in US market
Canadian battery developer Zinc8 Energy Solutions has announced plans to begin battery production in the United States, incentivized by manufacturing production credits in the US Inflation Reduction Act.
