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.

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.

BG Group sanctions US$15B coal seam gas to LNG project; first such

Green Car Congress

Estimated annual greenhouse gas emissions over the lifetime of the QCLNG project. BG Group has approved implementation of the first phase of a US$15-billion project to convert coal seam gas (CSG) to LNG—the first major commercial project to do so. More than half the emissions come from the LNG facility. Source: QCLNG EIS.

New catalysts enable photocatalytic version of water gas shift reaction for H2 production

Green Car Congress

PolitĂ©cnica de Valencia (Spain) have found that noble metal nanoparticles supported on titanium dioxide or cerium dioxide can catalyze the industrially important water gas shift (WGS) reaction for hydrogen production at ambient temperatures using visible light irradiation. —Sastre et al.

MIT Report Finds Natural Gas Has Significant Potential to Displace Coal, Reducing Greenhouse Gas Emissions; Role in Transportation More Limited

Green Car Congress

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. —MITEI Director Ernest J.

Hydro-Québec will support the clean hydrogen sector in Québec

Green Car Congress

Decarbonizing the economy to reduce greenhouse gas (GHG) emissions is one of the company’s priorities. In addition to having access to Québec’s vast water resources to generate green, renewable power at competitive prices, Hydro-Québec has everything it needs to support the development of green hydrogen. Renewable natural gas.

Researchers produce hydrogen from water and charcoal mix at room temperature using laser pulses

Green Car Congress

Researchers at Wakayama University in Japan have produced a mixture of hydrogen and carbon monoxide gas by irradiating a mixture of carbon powder and distilled water with intense nanosecond laser pulses at room temperature. The carbon or charcoal powders were dispersed in distilled water at a ratio of 25.8 mL volume of water.
