Proposed process for low-emissions coal-to-liquids

Green Car Congress

The EMS (Earth and Mineral Science) Energy Institute at Penn State has developed a conceptual novel process configuration for producing clean middle-distillate fuels from coal with some algal input with minimal emissions. Principal inputs are coal, water, non-carbon electricity, and make-up solvent. Background.

the ocean and surface waters) that received their CO 2 directly from ambient air. Most contemporary DAC approaches utilize energy poorly, as evident by second-law efficiencies for CO 2 separation of 1 to 9% (for comparison, post-combustion capture from coal exhaust attains second-law efficiencies greater than 20%).

Monash team proposes roadmap to renewable ammonia economy; 3 generations of technology

Green Car Congress

Generation 3 avoids the need for the Haber-Bosch process entirely by direct electrochemical conversion of N 2 to NH 3. The process generates H 2 from natural gas or coal through steam reforming and combines it with N 2 , which has been separated from air by a cryogenic process, to form NH 3. Note the logarithmic ordinate scale.

Geely invests in Carbon Recycling Intl.; vehicles fueled by methanol from CO2, water and renewable energy

Green Car Congress

Geely’s CRI investment and work with renewable methanol is similar to the approach Audi is taking with its own e-fuels projects—producing very low carbon liquid or gaseous fuels using only renewable energy, water and CO 2.

Review finds encouraging progress in electrochemical reduction of CO2 to organic compounds; substantial advances in catalysts, electrolytes and reactors still required

Green Car Congress

However, the two conclude in their review, substantial advances in catalyst, electrolyte, and reactor design are needed to enable CO 2 utilization via electrochemical conversion a technology that can help address climate change and shift society to renewable energy sources. —Whipple and Kenis. reduction.

Obama Announces Steps to Boost Biofuels, Clean Coal; RFS2, BCAP, BIWG and Carbon Capture and Storage Task Force

Green Car Congress

Second, the US Department of Agriculture proposed a rule on the Biomass Crop Assistance Program (BCAP) that would provide financing to increase the conversion of biomass to bioenergy. It’s been said that the United States is the Saudi Arabia of coal—and that’s because, as I said, it’s one of our most abundant energy resources.

EIA: China’s use of methanol in liquid fuels has grown rapidly since 2000; >500K bpd in 2016

Green Car Congress

This review consisted of a closer look at the refined products markets in China, and also a sectoral analysis of energy use. Methanol, like ethanol, is an alcohol with inherent issues such as its solubility in water and corrosiveness. EIA recently completed a re-assessment of energy use in China. Methanol in China.
