SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. If biogas is substituted for conventional natural gas, total GHG emissions can further significantly reduced (190 gCO 2 /mile). Lifecycle GHG comparison.

Underground Coal Gasification Company In Partnership to Test Alkaline Fuel Cells for Power Generation

Green Car Congress

Australia-based underground coal gasification (UCG) company Linc Energy ( earlier post ) has signed an exclusive agreement with the UK-based alkaline fuel cell technology company AFC Energy Plc and its related company, B9 Coal ( earlier post ). A downside of AFCs has been CO 2 contamination of the electrolyte, reducing efficiency.

Geely invests in Carbon Recycling Intl.; vehicles fueled by methanol from CO2, water and renewable energy

Green Car Congress

Geely’s CRI investment and work with renewable methanol is similar to the approach Audi is taking with its own e-fuels projects—producing very low carbon liquid or gaseous fuels using only renewable energy, water and CO 2. Their results showed that in comparison with gasoline mode, CO emitted in methanol mode decreased 11.2%.

The Case for Nuclear Cargo Ships

Cars That Think

Nearly all of the world’s ship fleet still runs on diesel fuel, with about a quarter of new ships on order being built to run on somewhat lower-carbon alternatives like liquefied natural gas, methanol, or hybrid propulsion. Shipping uses over 300 million tonnes of fossil fuels every year, producing 3 percent of greenhouse gas emissions.

New full LCA highlights complexity of environmental advantages and disadvantages of EVs relative to ICE vehicles; the importance of life cycle thinking

Green Car Congress

Researchers at the Norwegian University of Science and Technology (NTNU) have compared the emissions resulting from the production, use, and end-of-life of electric and internal combustion engine vehicles (EVs and ICEVs) in a full life-cycle analysis (LCA). This has led to a general perception of EVs as an environmentally benign technology.
