Twelve has developed an efficient polymer-electrolyte membrane (PEM) CO 2 electrolyzer that uses proprietary CO 2 -reducing catalysts to split CO 2 with just water and renewable electricity as inputs, syngas (CO and hydrogen) as the output, and pure oxygen as the only byproduct.

However, the resulting bio-oils are typically high in oxygen, water, solids and acids. 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. earlier post.).

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.)

Ignite Energy Resources supercritical water process diagram. IER’s proprietary supercritical water technology (SCW) transforms low-ranked coals, including lignite, directly into higher-valued oils and cleaner coal products. Work is expected to begin in mid-July with the initial plant operating by the second quarter of 2010.

SOLVE adds a solvent to the steam in SAGD (basic operation depicted above) to reduce energy input and water consumption. Unlike surface mined oil sands, in-situ recovery involves much less land disturbance, but still requires the use of water and natural gas in the steam production process. Source: StatoilHydro.

Macroalgae (seaweed) offers a number of attractive attributes as a feedstock for renewable fuels and chemicals (high sugar content, no requirements for arable land, fresh water, and fertilizer and no food vs. fuel issues. Ethanol production from glucan and mannitol yields approximately 0.08 wt ethanol/wt dry macroalgae. splendidus fragment.
