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

Green Car Congress

Both half reactions of water electrolysis—hydrogen and oxygen evolution—are unfortunately slow and require a lot of power. The material can be used as either an anode or a cathode, and demonstrates high activity and stability in the production of hydrogen and oxygen in the electrolysis of water. Zhang, S.L., and Lou, X.W.

NTNU researchers use reverse electrodialysis and waste heat for hydrogen production: Heat to H2

Green Car Congress

A new approach developed by researchers at the Norwegian University of Science and Technology (NTNU) could alleviate that situation a bit by using waste heat from other industrial processes. Energy experts say that the waste heat from Norway’s businesses and industries is the equivalent of 20 TWh of energy. —Krakhella et al.

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 ?

Oleophobic hydrophobic magnetic sponge selectively soaks up oil, sparing water and wildlife

Green Car Congress

A Northwestern Engineering-led team has developed a highly porous smart sponge that selectively soaks up oil in water. Currently used solutions include burning the oil, using chemical dispersants to breakdown oil into very small droplets, skimming oil floating on top of water and/or absorbing it with expensive, unrecyclable sorbents.
