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

Green Car Congress

Traditional methods of producing hydrogen without greenhouse gas emissions (green hydrogen) include electrolysis powered by renewable sources such as wind, solar, or hydro. According to a report from S&P Global Commodity Insights, the cost of electrolytic hydrogen from renewable energy spiked as high as $16.80/kg

Zhejiang team develops photo-chemo-biocatalytic pathway to convert triolein to biogasoline

Green Car Congress

Researchers from Zhejiang University in China have developed a photo-chemo-enzymatic multi-step combination pathway for the highly efficient and environmentally friendly preparation of biogasoline from cheap and sustainable triolein using solar energy and atmospheric O 2 under mild conditions. —Xu et al.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. These initiatives have largely focused on renewable electric power generation, distribution, and storage. Eronen says, laughing.

Delivery of renewable isooctane to Audi tips interesting potential non-biomass pathway for biogasoline; “e-benzin” as solar fuel

Green Car Congress

Last week, Audi and its partner Global Bioenergies announced that the first batch of renewable isooctane—which Audi calls “e-benzin”—using Global Bioenergies’ fermentative isobutene pathway (sugar→isobutene→isooctane) had been produced and presented to Audi by Global Bioenergies.

Rhodium Group estimates US GHG fell 2.1% in 2019, driven by coal decline

Green Car Congress

The switch from coal to natural gas and renewables in the electric power sector accounts for the majority of the progress the US has made in reducing emissions over the past decade. Natural gas generation made up much of the gap last year, as it has consistently in recent years, due to extremely cheap gas prices. Coal-driven decline.

Why is Hydroelectricity So Green, and Yet Unfashionable?

Cars That Think

There is no end of gushing about China’s cheap solar panels—but when was the last time you saw a paean to hydroelectricity? Instead, that pure status is now reserved above all for wind and solar. The manufacture of solar panels involves the environmental costs from mining, waste disposal, and carbon emissions.
