NREL modifies organism to produce ethylene via photosynthesis: alternative to fossil-fuel based ethylene for chemicals and transportation fuels

Green Car Congress

PCC 6803—and demonstrated that the organism remained stable through at least four generations, producing ethylene gas that could be easily captured. The organism produced ethylene at a high rate and is still being improved. into a cyanobacterium— Synechocystis sp. —Ungerer et al.

Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

The central process for this conversion is electrocatalytic water splitting in which hydrogen and oxygen are formed. Further, hydrogen is the starting point for the formation of other fuels such as methanol, ammonia, or liquid organic hydrogen carriers. Energy Environ. doi: 10.1039/D0EE03659E.

DOE awards $35M to 12 ARPA-E projects to reduce methane emissions; 5 on natural gas engines

Green Car Congress

The system will significantly increase methane conversion efficiency and comply with future stringent nitrous oxide regulations. The project team’s technology will consist of a novel methane oxidation catalyst (MOC) formulation capable of high conversion efficiencies at the lower exhaust temperatures in ultra-lean burn engines.

MOF-based cathode for Li-S battery shows long cycle life, high performance

Green Car Congress

Researchers from Peking University and Beijing Institue of Technology have designed a Li-sulfur battery cathode based on sulfur and a metal-organic framework (MOF) host. Metal-organic frameworks as a class are highly porous and well-defined crystalline materials, and a good prospect for such a host, the researchers posited.

IMO environment meeting adopts mandatory energy efficiency measures for international shipping; first mandatory global GHG reduction regime for an international industry sector

Green Car Congress

Mandatory measures to reduce emissions of greenhouse gases (GHGs) from international shipping were adopted by Parties to MARPOL Annex VI represented in the Marine Environment Protection Committee (MEPC) of the International Maritime Organization ( IMO ), when it met for its 62 nd session from 11 to 15 July 2011 at IMO Headquarters in London.
