ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

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.

MAN Energy Solutions wins pre-engineering contract for methanation reactor in Power-to-X Plant

Green Car Congress

The plant, with a total input capacity of 200 MW, will be built in Kristinestad, Finland for the production of green hydrogen and synthetic natural gas (SNG). Back in 2012, we commissioned the methanation reactor for what was, at that time, Europe’s largest power-to-gas plant with 6 MW in Werlte, Germany. Earlier post.)

Audi presents latest SQ5 TDI diesel; 48V MHEV & electric compressor

Green Car Congress

The SQ5 TDI was first introduced in the fall of 2012 as the first Audi S model powered by a diesel engine. This offers the advantage since exhaust gas cleaning responds more quickly. The exhaust manifold benefits from improved insulation; the exhaust gas reaches the optimum temperature more quickly after a cold start.

Austria-Germany Research Collaboration Developing Process to Store Renewable Electricity as Synthetic Natural Gas

Green Car Congress

Researchers in Austria and Germany are developing a process to store renewable electricity as synthetic natural through a combination of electrolysis to produce hydrogen combined with methanation using CO 2. The partners plan to launch a substantially larger system—approximately 10 MW—by 2012. Michael Specht of ZSW.

Topping-out ceremony for the Audi e-gas plant; synthetic methane production to begin in early 2013

Green Car Congress

Components of the e-gas plant. Audi is celebrating progress on its e-gas plant under construction in Werlte, Germany with a topping-out ceremony. End products from the plant will be hydrogen and synthetic methane (Audi e-gas), to be used as fuel for vehicles such as the new Audi A3 Sportback TCNG. Click to enlarge.
