Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. In both plants, natural gas turbines power the equipment.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. 3) Measurement.

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.

Report finds Coal-to-Liquids and Oil Shale pose significant financial and environmental risks to investors

Green Car Congress

Ceres recently released a new report concluding that coal-to-liquid (CTL) and oil shale technologies face significant environmental and financial obstacles—from water constraints, to technological uncertainties to regulatory and market risks—that pose substantial financial risks for investors involved in such projects.

IEA: governments must act to ensure sufficient supply of critical minerals to meet net-zero goals

Green Car Congress

Not only is this a massive increase in absolute terms, but as the costs of technologies fall, mineral inputs will account for an increasingly important part of the value of key components, making their overall costs more vulnerable to potential mineral price swings.

Altex & Unitel partner to demonstrate a new technology for making synthetic gasoline from biomass

Green Car Congress

coal, biomass, or waste—is heated in the absence of molecular oxygen to produce a solid containing char and ash and volatile gases. Altex has been working with the US Department of Energy (DOE) on developing a version of the process to convert a mixture of coal and biomass to jet fuel since 2012. Carbonaceous materials—e.g.,

EPA proposes rule for nationwide 30% cut in GHG from existing power plants by 2030 relative to 2005

Green Car Congress

Heat rate improvements result in any changes in equipment, operating procedures or maintenance practices that increase the efficiency of converting fuel energy into electricity by an EGU. The value allocated here in EPA’s goal-setting formula was an average heat rate improvement of 6% for coal steam electric generating units (EGUs).
