Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Our analysis assumes that captured carbon dioxide can be stored indefinitely, an optimistic and unproven assumption.

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.

UK to award £54M to 15 projects developing innovative carbon removal technology

Green Car Congress

The UK government is awarding £54 million to 15 projects to develop technologies that remove carbon emissions from the atmosphere. The carbon dioxide can then be permanently stored or used in various products or applications. The biochar is rich in carbon and can be used as a fertilizer. Cambridge Carbon Capture Ltd.,

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. We distinguished ammonium carbamate pairs and a mix of ammonium carbamate and carbamic acid during carbon dioxide chemisorption.

New catalyst opens door to CO2 capture in coal-to-liquids process

Green Car Congress

World energy consumption projections expect coal to stay one of the world’s main energy sources in the coming decades, and a growing share of it will be used in CT—the conversion of coal to liquid fuels (CTL). By 2020, CTL is expected to account for 15% of the coal use in China. —Wang et al.

Anglo American, Aurizon to explore feasibility of hydrogen-powered trains for bulk freight

Green Car Congress

Aurizon , Australia’s largest rail freight operator, and leading global mining company Anglo American will work together on a feasibility study to assess the introduction of hydrogen-powered trains for bulk freight. Rail freight already produces up to 16 times less carbon pollution per tonne kilometer than road. Earlier post.)

ArcelorMittal investigates hydrogen-based direct reduction of iron ore for steel production; CDA

Green Car Congress

To permanently reduce CO 2 emissions, steelmaker ArcelorMittal has developed a low-emissions technology strategy, which targets not only the use of alternative feedstocks and the conversion of CO 2 emissions, but also the direct avoidance of carbon (Carbon Direct Avoidance, CDA). —Frank Schulz, CEO of ArcelorMittal Germany.
