Solarwatt and Stiebel Eltron have agreed to cooperate on the development of heat pumps.
Stackable home battery with 9.6 kWh to 38.4 kWh of capacity
Lithion’s Stack’d Series LFP batteries are modular and can be scaled in 4.8 kWh increments, from 9.6 kWh to 38.4 kWh.
Self-healing perovskites can withstand fierce cosmic radiation
The development of a set of testing protocols for perovskite solar cells intended for use outside Earth’s atmosphere could lead to the devices being installed permanently, and even manufactured, on the moon.
Floating PV for unused swimming pools
Ciel & Terre Japan has deployed a floating solar plant on the swimming pool of a school on the Japanese island of Kyushu. Local developer ELM says the project could be extended to more than 6,000 facilities across the country.
US lab reveals top findings for hybrid solar, storage plants
US government researchers have collected 10 observations from recent research papers that look at solar- or wind-plus-storage power plants in the United States.
PV-powered portable seawater desalination system for drinking water
US researchers have developed a portable desalination unit that generates clean drinking water without filters or high-pressure pumps. The device is powered exclusively by solar energy and requires just 20 W of power per liter.
The Hydrogen Stream: Acid-treated cells produce about 200% more hydrogen
US scientists have improved the performance of intermediate-temperature electrolyzers based on protonic ceramic electrochemical cells. Germany and India have signed a hydrogen cooperation deal, while ArcelorMittal has tested the use of green hydrogen in the production of direct reduced iron at a steel plant in Canada.
