Germany’s Home Power Solutions has developed a hydrogen storage solution with a capacity of up to 15,000 kWh. The Picea system stores excess electricity from rooftop PV systems in the form of green hydrogen.

With a new system for floating photovoltaic power plants, engineers from Germany want to make the application cheaper, higher-yielding, and safer. The result is somewhat reminiscent of a pufferfish, which also gave the system its name.

Production waste puts a dent in the perception of sustainability of batteries. Northvolt, however, has partnered with a young Swedish company to make the best use of the battery production waste, and also help to decarbonize the fertilizer industry while they are at it.

The situation in the energy markets is tense. Following national pushes for action, the European Commission has now announced its set of recommendations to combat rocketing energy prices.

The manufacturer has launched sodium-ion products online. Production has begun and will be easily scalable, according to the CATL chairman. Researchers have been keen to make the technology work as it offers a cheaper, more environmentally friendly alternative to lithium-ion products.

Sax Power has developed a new residential battery which it describes as a game-changer in the battery technology.

The battery system, which is aimed at increased self-consumption, can handle a maximum DC input power of 18 kW and 1000 V.

Sonnen has published test results indicating the longevity of its storage systems after extended use.

A consortium led by The Mobility House has installed its first storage facility comprising both used and new Renault ZOE batteries in France, thus growing the network of such storage facilities in Europe.

India’s energy transition will not succeed without rooftop PV and roll-out is hindered not only by a lack of household finance, but by the fact many of the nation’s flat roofs are enjoyed by residents. Germany’s international development agency has proposed a solution.
