Electrolyser 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.

Storing hydrogen with ‘nano-chocolates’

German scientists have developed a novel hydrogen storage method that relies on nanostructures – tiny nanoparticles made of the precious metal palladium – instead of high pressure and lower temperatures.

New solution to store residential, commercial PV electricity as green hydrogen

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.

Puffer fish inspired floating PV structure

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.

Sodium-ion batteries a commercial reality, claims CATL

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.

German start-up offers 5.2 kWh AC battery that works without inverter

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

Sunday read: A PV band-aid

DuPont has developed a repair kit for PV modules with backsheet failures. Cracked and chalking backsheets can cause problems for solar project owners, but this could easily be addressed in the field without swapping out the PV modules. Stéphan Padlewski, regional marketing leader EMEA at DuPont Photovoltaic Solutions, spoke to pv magazine about how the solution works.

From toothbrushes to saving the planet: How ultrasonic delamination could hold the key to battery recycling

The use of ultrasonic sound waves has been applied to battery recovery. Researchers from the ReLiB project at the U.K.’s Faraday Institution say the process has already proven to be 100 times faster than conventional approaches. It is also much more sustainable and less energy intensive.

A repair tape for cracked backsheets

Backsheet failures have plagued the industry, causing hefty financial burdens to many asset owners. DuPont has launched a product it says allows for easy repair of modules.

Saturday read: the more you know

Module-level power electronics, most often in the form of power optimisers and microinverters, offer a range of value propositions, including advanced monitoring capabilities. But how much can the little box behind the module really see, and how much do operators actually need to know to keep a power plant running optimally?
