Universal Hydrogen successfully completes first flight of hydrogen fuel cell powered regional airliner

Green Car Congress

Universal Hydrogen has flown a 40-passenger regional airliner using hydrogen fuel cell propulsion. The flight, conducted under an FAA Special Airworthiness Certificate, was the first in a two-year flight test campaign expected to culminate in 2025 with entry into passenger service of ATR 72 regional aircraft converted to run on hydrogen.

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. The process is detailed in a paper in the journal ACS Sustainable Chemical Engineering. The process is detailed in a paper in the journal ACS Sustainable Chemical Engineering.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

The California-based Hyperlight Energy will be piloting an installation where they plan to use existing oil wells as solar thermal wellsprings, with the stored energy being converted back to clean electricity when required. Thermal energy storage is a known low-cost, low-risk approach for storing solar energy in the form of heat,” adds Codd.

Avantium acquires Liquid Light; electrocatalysis to convert CO2 to chemicals

Green Car Congress

Liquid Light has developed proprietary process technology to make major chemicals from low-cost, globally-abundant carbon dioxide. Spun out from Princeton University in 2008, Liquid Light has invested more than US$35 million on low-energy electrochemistry technologies to convert CO 2 to major chemicals.
