EIA: US energy-related CO2 emissions in 2012 lowest since 1994; reflects drop in coal use

Green Car Congress

The largest drop in emissions in 2012 came from coal, which is used almost exclusively for electricity generation. During 2012, particularly in the spring and early summer, low natural gas prices led to competition between natural gas- and coal-fired electric power generators.

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.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

BNEF, Snam, IGU report finds global gas industry set to resume growth post-pandemic; low-carbon technologies for long-term growth

Green Car Congress

After growing by more than 2% in 2019, global gas use is set to fall by around 4% in 2020, as the COVID-19 pandemic reduces energy consumption across the global economies. The report shows that medium-term growth will come from increasing cost-competitiveness and increased global access to gas. Low-carbon gas.

SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. If biogas is substituted for conventional natural gas, total GHG emissions can further significantly reduced (190 gCO 2 /mile). Lifecycle GHG comparison.

EPRI assesses status of 8 key power generation technologies for US; estimates of capital cost and levelized cost of electricity

Green Car Congress

Comparative levelized cost of electricity in 2025 ($/MWh) at different CO 2 prices. Representative costs are reported in constant December 2010 US dollars. LCOE calculations are based on assumptions regarding future unit operations, operating costs, fuel prices, financing terms, and inflation. Source: EPRI.

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

Green Car Congress

One possible scenario for the electricity system in the Western US in 2026-29. Their analysis also found that current renewable portfolio standards (RPS) are insufficient to meet emission reduction targets by 2030 without new policy. To meet these carbon goals, coal has to go away from the region. Click to enlarge.
