Researchers at Kyoto University in Japan have proposed a novel two-stage process to convert low-rank coals or biomass wastes under mild conditions to high-quality liquid fuel. Also, liquefying high-oxygen content low-ranking coal and biomass also consumes more hydrogen and produces more CO 2 , significantly reducing process efficiency.
These synthetic fuels are economically competitive with petro-diesel when the crude oil price (COP) is at or above $86 per barrel (based on a 20% rate of return, in January 2008 dollars, with a carbon price of zero). The study used one feedstock of each type—bituminous coal and switchgrass—to evaluate the CTL/CBTL/BTL processes.
An analysis of near-term spending plans on renewables by the biggest oil and gas companies shows that real investments in renewable energy will continue to pale in comparison to capex plans for greenfield fossil fuel projects. Let this sink in: In 2018, Big Oil spent less than 1% of its combined budget on green energy projects. 2 Total SA.
The concept’s key feature is the use of high-temperature heat from a solar concentrating tower to drive the chemical process of converting biomass to a biofuel, obtaining a near-complete utilization of carbon atoms in the biomass. Ten percent of carbon is oxidized and released to the environment. In comparison, cropland today covers 1.5

This year has brought a significant shift in the generating cost comparison between renewable energy and fossil fuels, according to detailed analysis by technology and region, published this week by Bloomberg New Energy Finance. In the US, coal and gas are still cheaper, at $65 per MWh, against onshore wind at $80 and PV at $107.
However, as the carbon intensity of the EU energy mix is projected to decrease, the life-cycle emissions of a typical electric vehicle could be cut by at least 73% by 2050. In future, with greater use of lower carbon electricity in the European mix the typical GHG emissions saving of BEVs relative to ICEVs will increase.
In particular, the study led by Drew Shindell found that methane emissions have a larger warming impact due to those interactions than accounted for in current carbon-trading schemes or in the Kyoto Protocol. Because the latter was a $126 billion/year market in 2008, even small differences in GWPs can have large economic consequences.
