TBEA unveils new residential inverters
TBEA has developed new products with nominal power ratings of 10 kW to 25 kW and efficiencies of 98.5%.
EV batteries alone could satisfy short-term grid storage demand
Low participation rates for vehicle-to-grid (V2G) tech of just 12% to 43% are needed to provide short-term grid storage demand throughout the world by as early as 2030, according to a group of Dutch and US researchers.
Japanese oil giant opens PV-powered hydrogen pilot in Australia
Japan’s largest oil company, Eneos, has opened a green hydrogen demonstration plant in Brisbane, Australia. The project is relatively small, producing just 20 kilograms of green hydrogen per day, but Eneos Senior Vice President Yuichiro Fujiyama says the company will expand it in the “near future.”
LG unveils heat pump for water heating
LG has developed an air source heat pump with the capacity to heat 200 liters to 270 liters of domestic water. It uses R134a as a refrigerant and the pump has a coefficient of performance (COP) of up to 3.85.
Only5mins! – Standards in agrivoltaics might limit innovation
