Swiss team sets record solar-to-hydrogen rate
Researchers from Switzerland’s École Polytechnique Fédérale de Lausanne have unveiled a new solar dish plant design, while Plug Power has delivered its first electrolyzer system to Europe.
Photocatalytic water splitting with 9.2% solar-to-hydrogen efficiency
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.
New method could potentially produce hydrogen from biogas for $2/kg
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.
US startup claims hydrogen output for $0.85/kg or less via new water vapor electrolyzer
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.
Electrolyzer sales expected to quadruple this year globally
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.
Electrolyzer ramping from 0 to 50,000 amperes in less than 10 seconds
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.
GAIL to build 4.5 tpd green hydrogen plant
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.
New solar-powered hydrogen tech from Japan
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.
DNV publishes guidelines for proper deployment of floating PV
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.
