Renault makes public its lifecycle study of Fluence ICE vs Fluence EV

Green Car Congress

Renault’s comparison of the carbon footprint of EV and ICE vehicles over production, operation and end of life. The study used the series production versions launched in 2011, with the assumption of operation for 150,000 km (93,205 miles). water, and non-renewable energies (crude oil, coal.) Click to enlarge.

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

The IMO’s previous goal was a 50 percent reduction by 2050 in comparison with 2008 levels. At the same time, it’s becoming apparent that alternative-fuel solutions we’re looking at have big drawbacks, and that producing these fuels will take a lot of green power that will be needed to replace coal and gas on shore.

U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. The upper and lower bounds for the projects studied were a NER of 6.1 (16% —Nduagu & Gates.

Researchers Propose Solar-Driven Biomass Gasification Pathway for Synthetic Fuel Production

Green Car Congress

Hydrogen for reverse water gas shift reaction to avoid producing CO 2 during the process is produced by electrolyzing water, driven by solar power. For comparison, they also modeled the production of methanol using only biomass as a fuel and also using coal as source of both carbon and energy. Hertwich and Zhang (2009).
