Twelve and Alaska Airlines to collaborate with Microsoft to advance sustainable aviation fuel derived from recaptured CO2 and renewable energy

Green Car Congress

Through the first-of-its-kind agreement, Twelve, Alaska, and Microsoft will work to advance production and use of Twelve’s E-Jet, a low-carbon jet fuel produced by a power-to-liquids process leveraging the company’s carbon transformation technology. Earlier post.). SAF is a core part of Alaska’s five-part pathway to net zero by 2040.

Tunable high-yield catalytic approach converts pyrolysis oil to bio-hydrocarbon chemical feedstocks including fuel additives

Green Car Congress

The zeolite catalyst then converts these hydrogenated products into light olefins and aromatic hydrocarbons in a yield as much as three times higher than that produced with the pure pyrolysis oil. The C 6 to C 8 aromatic hydrocarbons can be high-octane gasoline additives or feedstocks for the chemical and polymer industries.

Review of approaches to engineer microbes to produce advanced biofuels

Green Car Congress

The photosynthetic organisms will use sunlight to convert CO 2 to sugar, which the Shewanella will then convert to bio-hydrocarbons. Renewable fuels contain carbon derived from carbon dioxide. —Wackett 2010. Lawrence P Wackett (2010) Engineering microbes to produce biofuels. Earlier post.).

Mascoma Announces Feedstock Processing and Lignin Supply Agreement with Chevron Technology Ventures; Chevron Working on Converting Lignin to Hydrocarbon Fuel Components

Green Car Congress

Mascoma will then convert the feedstock to cellulosic ethanol through its proprietary process, which produces lignin as a by-product. Chevron has filed applications for two patents on processes to convert lignin to a hydrocarbon feedstock via hydroprocessing; both applications were published on 3 September 2009. Earlier post.)

LanzaTech exploring lipids production as part of its CO2 to acetic acid plans; pathways to renewable fuels

Green Car Congress

In CO fermentation, explained LanzaTech Communications Director Freya Burton, CO can serve as the carbon and the energy source whereas CO 2 can serve only as the carbon source. LanzaTech envisions using partner technology to convert the acetic acid to lipids—i.e., Carbon Dioxide as a Feedstock. Earlier post.).
