Electrolyzer

Scientists at the Australia National University have observed a key stage in the process of photosynthesis which could be copied to greatly increase the efficiency of sunlight-powered water splitting processes used to produce hydrogen.

Researchers at Stanford University have developed a type of electrode which is highly resistant to salt corrosion, therefore allowing them to produce hydrogen using seawater. Applied at a larger scale, this development could potentially cut the cost of power-to-gas applications by greatly increasing the amount of water available.

The Energy Storage Europe conference and trade show is nearing and pv magazine is featuring the top ten developments in the field as our Energy Storage Highlights, selected by an independent jury of experts. We kick off with Proton Motor’s contribution to a Swiss project that enables apartment tenants to live without a gas or electricity grid connection.

The CEOG scheme consists of a 55 MW solar park and 140 MWh storage station based on hydrogen which, according to the project developer, enables the storage of large amounts of energy for long periods

There is a solid business case to combine PV plants with electrolyzers, as generation costs are low enough to competitively produce hydrogen as a fuel, says Bjørn Simonsen of NEL Hydrogen. He will speak at pv magazine’s Future PV event at SPI in Las Vegas.
