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.

Stanford GCEP awards $6.6M to 7 projects; focus on combining energy conversion with carbon-neutral fuel production

Green Car Congress

The work represented by these GCEP awards is critical for the future. The goal is to design a novel fuel cell that uses coal and water to generate hydrogen, water and a stream of carbon dioxide gas, which can be captured and sequestered. High-efficiency thin-film solar cells.

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

For future scenarios where vehicle technology costs were sufficiently competitive to advantage either hydrogen or electric vehicles, the increased availability of low-cost, low-CO 2 electricity/hydrogen provided more cost-effective CO 2 mitigation opportunities in the heat and power energy sectors than in transportation.

Separate MIT, IEA reports both outline major expansion in role of natural gas; caution on climate benefits

Green Car Congress

The new report, part of the World Energy Outlook (WEO) 2011 series, examines the key factors that could result in a more prominent role for natural gas in the global energy mix, and the implications for other fuels, energy security and climate change.

Mad Power thoughts

EV Info

Climate Change. And while preventing working people earning a livelihood may make them feel good, it does nothing to solve the real problem of climate change. . Yet this crisis is a mere harbinger of the candle-lit future that awaits us if we do not change course. Gas is the only answer.

NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

Our results suggest that gas-aerosol interactions play an important role in methane’s GWP, and hence our larger value would allow better optimization of climate change mitigation policies. Methane’s GWP may also change with time as air quality regulations alter the background state of tropospheric chemistry. Drew Shindell.
