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. This is done through the sustainable extraction of natural resources, carbon negative production of chemicals, and closed-loop renewal of waste as feedstock.

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

Green Car Congress

Natural gas generation made up much of the gap last year, as it has consistently in recent years, due to extremely cheap gas prices. Renewables played an important role as well thanks in part to continued cost declines in both wind and solar generation. year-on-year. Industrial emissions (both energy and process) rose by 0.6%.

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.

We’re the New Renewables

Cars That Think

Now residential and commercial buildings can be outfitted with roofing tiles that double as solar panels, or with rooftop boxes like this low-profile unit that transforms gusts of wind into electric current. This WindBox turbine, installed on the roof of a building in Rouen, France, is 1.6 Our bodies slough off a ton of heat too.

It’s about one-twentieth the size of the minibus-scale geostationary satellites already in orbit, allowing for cheap and quick deployment. United States’ Wind on the Wire The largest renewable-energy infrastructure project in U.S. history— an $8 billion wind farm and transmission line —is set to begin construction in 2023.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

As countries transition away from fossil fuels to green sources of energy like wind and solar, there will be natural lulls in energy production due to weather conditions. If a substantial amount of solar or wind energy is on the grid, customers would be able to save money by purchasing and storing electricity during low-rate times.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Especially for sources like wind and solar, which have discontinuous availability. They used nickel and aluminium as materials for the cathode and anode respectively, with sodium aluminium tetrachloride (NaAlCl 4 ) as the molten-salt electrolyte—all relatively cheap, earth-abundant materials.
