Chalmers team develops method to reduce levels of mercury in sulfuric acid

Green Car Congress

In 2015, about 2,200 tonnes of mercury were emitted into the air as a result of human activities such as cement manufacture, small-scale gold mining, coal burning, metal production and other manufacturing industries. The limit values for how much mercury sulfuric acid may contain are based on the technology available today.

Report finds says “negative emissions technologies” need to play a large role in mitigating climate change

Green Car Congress

Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks.

Renewable-methanol fueled Geely cars in fleet testing in Iceland; 70% reduction in WTW CO2 compared to gasoline

Green Car Congress

Methanol which is produced with CRI’s method is one of the most environmentally friendly liquid fuels available today. Currently, China produces most of its methanol from coal. CRI’s current plant has a renewable methanol production capacity of 4,000 metric ton/year. The most common blend contains 15% methanol and 85% gasoline.

Additionally, few of current harvesting and dewatering technologies available today are amenable to scaling for larger production scenarios of 1,000 acre or larger algal farms. Algae cultures tend to be relatively dilute, and the energy requirement to remove water from the cultures can be a significant portion of the energy balance.

DOE to award $30M to develop small-scale solid oxide fuel cell systems and hybrid energy systems

Green Car Congress

Thus, SOFC systems available today are heavily subsidized. Cleaning process for coal-derived syngas to be used as SOFC fuel and testing of single and multiple cells on syngas. To control IGSOFC system cost effectively, coal-derived syngas cleanup process for the removal of the contaminants is required to de developed.

Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications

Green Car Congress

They considered state-specific contributions from nine generating technologies: coal, oil, natural gas, hydro, biogas, geothermal, nuclear, wind, and solar. Renewable and nuclear electricity supply technologies are available today. Still, it is technically achievable. —Meier et al.

Study suggests current levels of methane leakage would result in numerous decades of more rapid climate change from a shift to natural gas vehicles

Green Car Congress

A) CNG light-duty cars vs. gasoline cars; (B) CNG heavy-duty vehicles vs. diesel vehicles; and (C) combined-cycle natural gas plants vs. supercritical coal plants using low-CH 4 coal. A TWP >1 means that the cumulative radiative forcing from choosing natural gas today is higher than a current fuel option after t yr.
