Green Car Congress

The Rhodium Group, an independent research provider, estimates that, after a sharp uptick in 2018, US greenhouse gas (GHG) emissions fell by 2.1% This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by a record 18% year-on-year to its lowest level since 1975. Coal-driven decline.

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.

Bloomberg NEF forecasts falling battery prices enabling surge in wind and solar to 50% of global generation by 2050

Green Car Congress

The arrival of cheap battery storage will mean that it becomes increasingly possible to finesse the delivery of electricity from wind and solar, so that these technologies can help meet demand even when the wind isn’t blowing and the sun isn’t shining. Coal emerges as the biggest loser in the long run. BNEF sees $1.3

Opinion: Why Buffett Bet A Billion On Solar: Miles Per Acre Per Year

Green Car Congress

During the late innings of the ICE-age (as in the Internal Combustion Engine age) it has become clear that feeding gasoline and diesel to the next billion new cars is not going to be easy, or cheap. Coal still supplies more power in the US than anything else, with natural gas next. Unfortunately, they don’t. Click to enlarge.

are various sources of hydrogen, such as steam methane reforming of natural gas and gasification of biomass into syngas that can make hydrogen cheaper. ARPA-E has already made transitions to focus funding on gas-to-liquids (GTL) technologies amidst cheap natural gas prices in the US in recent years. Hydrogen-to-fuels.
