Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.

SAF company DG Fuels closes investments with two Japanese companies

Green Car Congress

These facilities typically use approximately one ton of coal to produce one BBL of hydrocarbons, with a life cycle CO 2 emissions calculation that is slightly worse than equivalent fuels derived from conventional oil refining. DGF replaces the coal gasification used by others with biomass gasification and natural gas reforming.

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.

Energy Vault to provide 1.6 GWh of gravity energy storage to support DG Fuels SAF projects

Green Car Congress

Energy Vault’s advanced gravity energy storage solutions are based on the proven physics and mechanical engineering fundamentals of pumped hydroelectric energy storage, but replace water with custom-made composite blocks, or “mobile masses”, which do not lose storage capacity over time.

CSIRO and partners to test Direct Injection Carbon Engine to reduce brown coal emissions by up to 50%

Green Car Congress

DICE involves converting coal or biomass into a water-based slurry (called micronised refined carbon, MRC) that is directly injected into a large, specially adapted diesel engine. The process has very high conversion efficiency >97% (LCA); he fuel choice determines the carbon footprint. DICE development network.

Study finds heavy-petroleum fuels raising vanadium emissions; human emissions outpacing natural sources by factor of 1.7

Green Car Congress

Human emissions of vanadium to atmosphere now exceed natural sources by a factor of 1.7 and are destined to rise significantly with the use of heavy oils, tar sands, and bitumen as combustion sources. Vanadium is a trace metal found in many earth materials, including petroleum and coal.

A Glimpse Into The Post-Oil Era: How The Uneven Impacts Of 2025-2030 Peak Oil Demand Will Shape The Future Of Energy

As Sheikh Zaki Yamani, a former Saudi oil minister, once said, “The stone age came to an end not for a lack of stones, and the oil age will end, but not for a lack of oil.” But some oil will still be being pumped at the end, and it won't be heavy, sour, far from water crude.
