Novel inexpensive cobalt-nickel electrode for efficient water and urea electrolysis; yolk-shell nanoparticles

Green Car Congress

Electrolytic hydrogen production powered by renewable energy is seen as an environmentally friendly means to ameliorate global climate and energy problems. Both half reactions of water electrolysis—hydrogen and oxygen evolution—are unfortunately slow and require a lot of power. Zhang, S.L., and Lou, X.W.

UNIST team develops novel hydrogen production process using biomass oxidation instead of water oxidation as electron source

Green Car Congress

Korea’s Ulsan National Institute of Science and Technology (UNIST) have developed a novel process for the production of hydrogen using various types of biomass, including lignin, as an efficient alternative to water oxidation as an electron source. Conventionally, water is considered a cheap and clean source of electrons; 2H 2 O ?

Toyota and DIFFER partner on direct solar production of hydrogen from humid air, rather than water

Green Car Congress

The Dutch Institute for Fundamental Energy Research ( DIFFER ) is partnering with Toyota Motor Europe (TME) to develop a device that absorbs water vapor, and splits it into hydrogen and oxygen directly using solar energy. One of these sustainable fuels is hydrogen, which can be used to store renewable energy.

Repsol produces renewable hydrogen from biomethane from urban solid waste

Green Car Congress

Spain-based energy and petrochemical company Repsol has produced renewable hydrogen using biomethane as raw material for the first time. This renewable hydrogen was used to manufacture fuels with a low carbon footprint, such as gasoline, diesel, or kerosene for aviation. Repsol has had a circular economy strategy in place since 2018.
