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.

Berkeley study finds renewable portfolio standards insufficient to meet 2030 GHG emission targets; new policy required

Green Car Congress

The least expensive way for the Western US to reduce greenhouse gas emissions enough to help prevent the worst consequences of global warming is to replace coal with renewable and other sources of energy that may include nuclear power, according to a new study by University of California, Berkeley, researchers.

DOE awarding $72M to 27 projects to develop and advance carbon capture technologies, including direct air capture

Green Car Congress

Under this cost-shared research and development (R&D), DOE is awarding $51 million to nine new projects for coal and natural gas power and industrial sources. In prior work with DOE, MTR has advanced membrane CO 2 capture technology for coal power plants through small engineering scale testing and studies. ION Clean Energy Inc.

MIT/RAND Study Concludes Three Types of Alternative Jet Fuel May Be Available in Commercial Quantities Over the Next Decade

Green Car Congress

The five different fuel groups were those derived: from conventional petroleum; from unconventional petroleum; synthetically from natural gas, coal, or combinations of coal and biomass via the FT process; renewable oils; and alcohols.
