Inorganic mercury converted to more toxic and bio-accumulative monomethylmercury in ocean waters, possibly by microbes

Green Car Congress

A team led by the University of Alberta has confirmed that inorganic mercury (Hg) found worldwide in ocean water is transformed into monomethylmercury (MMHg)—a potent and bio-accumulative neurotoxin—in the seawater.

Audi in new e-fuels project: synthetic diesel from water, air-captured CO2 and green electricity; “Blue Crude”

Green Car Congress

Audi’s latest e-fuels project is participation in a a pilot plant project in Dresden that produces diesel fuel from water, CO 2 and green electricity. The sunfire plant, which operates according to the “power-to-liquid” (PtL) principle, requires carbon dioxide, water and electricity as raw materials. Click to enlarge.

Boeing partners with South African Airways to convert Solaris energy tobacco into jet fuel

Green Car Congress

Initially, oil from the plants seeds will be converted into jet fuel. As part of that effort, they are working with the Roundtable on Sustainable Biomaterials to position farmers with small plots of land to grow biofuel feedstocks that provide socioeconomic value to communities without harming food supplies, fresh water or land use.

New fast hydrothermal process converts 65% of wet algae feedstock sample to biocrude in one minute

Green Car Congress

Phillip Savage at the University of Michigan has found that with appropriate parameters, hydrothermal liquefaction (HTL) can convert 65% of wet algae (a Nannochloropsis species) into biocrude in one minute. They saw their best results, with about half of the algae converted to biocrude, after treating it for 10 to 40 minutes at 570 degrees.

Renmatix and Virent collaborate on converting cellulosic sugars to renewable chemicals and packaging

Green Car Congress

Renmatix and Virent announced a strategic collaboration to convert affordable cellulosic sugars to renewable chemicals and bio-based packaging materials. An alternative to current petro-based materials, Renmatix’s C5 (xylose) and C6 (glucose) Plantro sugars are produced by an advanced water-based method known as supercritical hydrolysis.

Topsoe enters agreement with Steeper Energy to introduce complete waste-to-biofuel solution

Green Car Congress

Simplified Hydrofaction Process Hydrothermal liquefaction (HTL) applies supercritical water as a reaction medium for the conversion of biomass directly into a high-energy density renewable biocrude oil. The inherent low oxygen content of Hydrofaction Oil supports less secondary upgrading to convert the biocrude oil into finished fuels.
