Cemvita demonstrates “gold hydrogen” production in situ, sets up subsidiary

Green Car Congress

Cemvita defines Gold Hydrogen as the biological production of hydrogen in the subsurface through the consumption of trapped or abandoned resources. This is done through the sustainable extraction of natural resources, carbon negative production of chemicals, and closed-loop renewal of waste as feedstock. kg in late July 2022.

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

Green Car Congress

In principle, it is possible to produce valuable chemicals such as hydrogen, syngas, hydrocarbons, and alcohols through electrochemical processes using electricity from renewable energy resources. Conventionally, water is considered a cheap and clean source of electrons; 2H 2 O ? Hyeonmyeong Oh, Yuri Choi, Changhwan Shin, et al.

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

Green Car Congress

To address these problems in the previous works during the selective lithium recovery from the spent LFP batteries, it is significant to develop an oxidant that is cheap, green, and efficient as well to replace the existing oxidants. —Jin et al. The researchers found that 99.3% The researchers found that 99.3% Hao Jin et al.

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

Green Car Congress

With an ability to absorb more than 30 times its weight in oil, the sponge could be used to clean up oil spills inexpensively and efficiently without harming marine life. Oil spill clean-up is an expensive and complicated process that often harms marine life and further damages the environment. —Vikas Nandwana. Ribet, Roberto D.

Perspective: Drive Star Conversion Program Could Cut US Oil Use in Half by 2020

Green Car Congress

Now are we still stuck maintaining our addiction with clean needles, or, best case, settling for methadone? Even on land, getting oil from tar sands depletes water and other resources and doubles oil’s carbon footprint. And oil only seems cheap. But let’s realize: defending our nation is never cheap.

Naysayer Alert – the hydrogen red herring

My Electric Car

The only by products are water and a fair degree of heat, the latter indicating a degree of inefficiency and wasted energy. If taken from such sources, hydrogen is a fossil fuel, and is not a renewable resource. Hence its supply would not be cheap, renewable nor sustainable in the long term.
