Converting Coal Power Plants to Nuclear Gains Steam

Cars That Think

On a planet aspiring to become carbon neutral, the once-stalwart coal power plant is an emerging anachronism. It is true that, in much of the developing world, coal-fired capacity continues to grow. But in every corner of the globe, political and financial pressures are mounting to bury coal in the past.

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

Green Car Congress

To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change, according to a new report from the National Academies of Sciences, Engineering, and Medicine.

B9 Coal Assembles Consortium to Combine Underground Coal Gasification, Alkaline Fuel Cells and Carbon Capture and Storage

Green Car Congress

UK-based B9 Coal, established in 2009 with the objective of developing projects combining Underground Coal Gasification (UCG) with Carbon Capture and Storage (CCS) and alkaline hydrogen fuel cells, is bringing together a consortium including WSP Group, AFC Energy and Linc Energy to develop such a project.

Oxford Team Outlines Progress and Potential in CO2 Capture and Conversion to Synthetic Transportation Fuels

Green Car Congress

The authors highlight three possible strategies for CO 2 conversion by physico-chemical approaches: sustainable (or renewable) synthetic methanol; syngas production derived from flue gases from coal-, gas- or oil-fired electric power stations; and photochemical production of synthetic fuels.

Discovery of mechanism for atmospheric particle formation suggests need for ammonia emission regulations

Green Car Congress

What we found is that the nitric acid and ammonia are susceptible to temperature changes. When the temperature gets colder, they can actually go through the gas to particle conversion process, creating new particles and increasing the overall particle number concentration. The emission sources are limited up there. —Neil Donahue.

Study Finds Availability of Low-CO2 Electricity and Hydrogen May Paradoxically Delay Large-Scale Transition to Electric and/or Hydrogen Vehicle Fleet

Green Car Congress

The cost-effectiveness of measures to address climate change is enhanced through a multisector perspective. Primary energy sources in model include fossil fuels (crude oil, natural gas, and coal); non-renewable non-fossil sources (nuclear); and renewable sources (hydroelectric, wind, solar, and biomass).

trillion in 2010) would be required to overcome poverty; increase food production to eradicate hunger without degrading land and water resources; and avert the climate change catastrophe. At present, there are only a few evident niches in which cost-insensitive end-users might be persuaded to pay for environmental public goods.
