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 ?

Efficient recovery of lithium from spent LiFePO4 batteries via air oxidation–water leaching at room temperature

Green Car Congress

Researchers in China report using air oxidation–water leaching to recover lithium selectively from spent LiFePO 4 (LFP) material, in which the high leaching efficiency of lithium and the good separation effect of lithium and iron were achieved simultaneously. An open-access paper on their work is published in the RSC journal Green Chemistry.

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.

ICL researchers develop new membrane-based system for cheap, efficiently made biofuels

Green Car Congress

In contrast to water, the extractant does not form a heterogeneous azeotrope with n-butanol, and the overall energy consumption of for n-butanol production is 3.9 Biofuels can be produced by fermenting waste biomass and recovering the fuel from the fermented solution using an extractant.

Looking to get in a hybrid for cheap? Used Toyota Prius 1.5 HSD 2004-2009 Review

Green Car Congress

I knew I wanted something for her that was cheap to maintain, had a reliable automatic transmission, came with cruise control, AC. Sometimes the engine water pump might leak. It is something very cheap to fix and to inspect. We used silicone to seal it on ours and the cabin is 100% water tight ever since.

Blue World Technologies takes 15% stake in Danish Power Systems; methanol fuel cell vehicles

Green Car Congress

A closed thermal integration enables reuse of fuel cell waste heat for fuel evaporation thereby increasing efficiency. Methanol reforming converts a mix of methanol and water into a hydrogen-rich gas. Waste heat can be utilized for cabin/battery heating and fuel tank can be placed where chassis design allows it.

Why is Hydroelectricity So Green, and Yet Unfashionable?

Cars That Think

I live in Manitoba , a province of Canada where all but a tiny fraction of electricity is generated from the potential energy of water. There is no end of gushing about China’s cheap solar panels—but when was the last time you saw a paean to hydroelectricity? Construction of large dams began before World War II.
