California 2017 GHG inventory shows 1.2% total drop from 2016; transportation sector emissions up 1%

Green Car Congress

Changes in emissions by Scoping Plan sector between 2000 and 2017. The transportation sector remains the largest source of GHG emissions in the state, and saw a 1% increase in emissions in 2017. The transportation sector represents tailpipe emissions from on-road vehicles and direct emissions from other off-road mobile sources.

Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

Net positive RF (warming) contributions arise from CO 2 , water vapor, NO x , and soot emissions, and from contrail cirrus (consisting of linear contrails and the cirrus cloudiness arising from them). These contributions involve a large number of chemical, microphysical, transport and, radiative processes in the global atmosphere.

Wärtsilä and partners developing emissions-free barge concept

Green Car Congress

The concept is supported by the Dutch Ministry of Infrastructure and Water Management. Within the Netherlands transport sector, inland navigation accounts for 5% of carbon dioxide emissions. With the help of a 2000 kWh Repack container, an inland vessel can sail for two to four hours.

KAUST team devises electrically-driven membrane process for seawater lithium mining

Green Car Congress

Unlike conventional membrane processes where the transport proceeds down the concentration gradient, the electrically-driven membrane process can up-grade the concentration; this system has been commercialised for use in the purification of hydrogen. In addition, this process runs continuously, and is easy to scale up.

EIA: China’s use of methanol in liquid fuels has grown rapidly since 2000; >500K bpd in 2016

Green Car Congress

Annual methanol consumption in China, 2000-16. The sectoral analysis of energy use suggested that previous data for liquid fuel use in China’s transportation sector were underestimated. Methanol, like ethanol, is an alcohol with inherent issues such as its solubility in water and corrosiveness. Click to enlarge. Background.

Bright Automotive To Convert VW Transporters to Plug-ins

Green Car Congress

A VW Transporter van. Start-up Bright Automotive, which in May unveiled its IDEA concept series plug-in hybrid light commercial van ( earlier post ), will convert VW Transporter vans with the series hybrid Bright powertrain as a bridge between the concept and the production version of the IDEA. The Bright IDEA and Transporter PHEV.
