UCLA team uses engineered microbe and electricity to convert CO2 to higher alcohols

Green Car Congress

An integrated electromicrobial process to convert CO 2 to higher alcohols. Electricity powered the electrochemical CO 2 reduction on the cathode to produce formate, which is converted to isobutanol and 3MB by the engineered R. Liao (2012) Integrated Electromicrobial Conversion of CO 2 to Higher Alcohols. Click to enlarge.

Power-to-gas trial to inject hydrogen into Australia’s gas grid; A$5M award to AquaHydrex

Green Car Congress

The Australian Renewable Energy Agency (ARENA) announced a trial for a new type of electrolyzer which could see excess renewable energy stored in the gas grid and used to decarbonize Australia’s gas supply. Storing renewable energy directly in the gas network was a logical first route to market for the invention.

Amminex City-SCR upgrade delivers gaseous ammonia for improved SCR conversion of NOx; avoiding high off-cycle emissions

Green Car Congress

Urea-driven SCR system use exhaust heat to convert the urea solution to ammonia, which then reduces the NO x. SCR effectiveness is also temperature-dependent: Below some threshold for exhaust temperature, the injected urea cannot be converted to ammonia. At low exhaust temperatures, catalyst activity also falls off sharply.

EnerG2 develops new carbon adsorbent material for on-board natural gas storage

Green Car Congress

One possible solution is adsorbed storage; the interest is so keen, that ARPA-E awarded a combined $10.875 million in 2012 to four different projects (led by Ford, GTI, Texas A&M and SRI) to develop new sorbent materials for on-board natural gas storage. Earlier post.).

Lima Energy signs 10-year synthetic crude supply contract with Husky Energy refinery in Ohio

Green Car Congress

The Lima Energy Company acquired the 63-acre property for the construction of the Lima Energy Project from the City of Lima, Ohio, in October 2012. The Lima Energy Project is being designed to convert solid hydrocarbon (coal, petroleum coke, and renewables) feedstock into synthetic crude.

Japan-US team develops novel catalyst for reversible hydrogen storage under mild conditions using CO2, formate and formic acid

Green Car Congress

This diagram shows the new catalyst in its protonated and deprotonated states as it reversibly converts hydrogen and CO 2 gas to and from liquid formate or formic acid at ambient temperature and pressure. Their goal was to design new catalysts with improved performance. Click to enlarge. Hull et al. Click to enlarge.

GKN to supply 500 electric flywheel hybrid drive systems to Go-Ahead Group for buses

Green Car Congress

The energy is drawn from the flywheel and converted back into electricity to power the traction motor, which helps accelerate the bus back up to speed, generating fuel savings of more than 20% at a significantly lower cost and weight (60 kg, 132 lbs) than battery hybrid alternatives. Useable stored energy is 1.2MJ, with peak power of 120kW.
