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 billion in 2020.

Researchers produce high density renewable fuels from terpenes; potential use as significant components of jet, diesel and tactical fuels

Green Car Congress

Researchers at the Naval Air Warfare Center, Weapons Division (NAWCWD) at China Lake have developed a process for the synthesis of high energy density renewable fuels through the selective dimerization of α-pinene, camphene, limonene and crude turpentine using the heterogeneous catalysts Nafion, Nafion SAC-13, and Montmorillonite K-10.

Chalmers team identifies two main challenges for bio-hydrocarbon fuel production from cheap sources

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have identified two main challenges for renewable biofuel production from cheap sources: lowering the cost of developing microbial cell factories; and establishing more efficient methods for hydrolysis of biomass to sugars for fermentation.

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 ?

UC Davis process produces gasoline-range hydrocarbons from biomass-derived levulinic acid; field-to-tank yield of >60% claimed

Green Car Congress

As a very rough benchmark on yield, cellulosic gasoline and diesel company KiOR, which uses a different pathway for fuel production (the production of renewable crude from biomass followed by catalytic cracking to upgrade to fuels), calculates that one bone dry ton of woody biomass contains hydrocarbons approximately equal to 2.8 gallons US).

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.
