A US research team has developed a new technique to produce hydrogen from sunlight and water. It works in an indoor environment and uses pure water, concentrated solar light, and an indium gallium nitride photocatalyst.

Kore, an energy startup in California, has developed a new way to produce hydrogen from biogas, and is now poised to build a commercial-scale demonstration facility in Los Angeles. It said half of the carbon in the feedstock can be converted into gas, while the other half can be converted into solid elemental carbon char.

Advanced Ionics has developed an electrolyzer that runs at temperatures below 650 C. It is reportedly able to produce hydrogen for $0.85/kg or less. CEO Chad Mason recently spoke with pv magazine to provide a closer look at the water vapor electrolysis tech.

According to BloombergNEF, electrolyzer shipments may reach up to 2.5GW in 2022, up significantly from 458MW last year. China and the United States will become the world’s first and second markets, respectively.

Developed by Canada-based Hydrogen Optimized, the electrolyzer can be used to stabilize electrical grids and optimize energy recovery from intermittent renewable power sources such as solar and wind. Furthermore, this week four more big international partnerships for developing green hydrogen were announced across Germany, the Middle East, and Australia.

India’s largest state-owned natural gas company is looking to buy a 10 MW electrolyzer to produce 4.5 tons of green hydrogen daily.

Moreover, two big Russian corporations have unveiled plans to produce hydrogen and Portuguese utility EDP said it wants to set up a a pilot project for a green hydrogen plant in Brazil.

The Recommended Practice guide, on top of describing the most common requirements for building a floating PV array, provides a series of technical guidelines for electrical safety, anchoring and mooring issues, operation and maintenance, and specific plant design that can withstand site-specific environmental conditions.
