ABB introduces Dynafin propulsion system to increase ship efficiency; mimicking movements of whale tail

Green Car Congress

The new propulsion concept features a main electric motor that powers a large wheel rotating at a moderate 30-80 rounds per minute. This can deliver significant savings in fuel consumption and help to avoid emissions. The new concept is the latest addition to ABB’s portfolio comprising electric, automated and digital technologies.

Study finds renewable fuel mandates alone not likely to lower carbon intensity of biofuels; the importance of localized LCAs and optimized low carbon fuel standards

Green Car Congress

In a paper published in the journal Energy Policy , the team suggests that more effective policies would evaluate fuels at the refinery level, thereby creating incentives for GHG emissions to be lowered through competition as low GHG emission fuels have higher economic value to blenders. Refiners are improving efficiency.

WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

A team of biologists and engineers modified Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity and light. We hope that it can be a steppingstone for future sustainable solar fuel production.

MIT study concludes that absent climate policy, coal-to-liquids could account for around a third of global liquid fuels by 2050

Green Car Congress

A new assessment of the viability of coal-to-liquids (CTL) technology by researchers from the MIT Joint Program on the Science and Policy of Global Change (JPSPGC) found that without climate policy, CTL has the potential to account for around a third of global liquid fuels by 2050. of global electricity demand.
