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.

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.

8 Rivers announces 8RH2 CO2 Convective Reformer for ultra-low carbon hydrogen production from natural gas

Green Car Congress

8 Rivers Capital announced the development of the 8RH2 CO 2 Convective Reformer—a technology for the production of ultra-low carbon hydrogen from natural gas. It uses the oxy-combustion of carbon fuels and a high-pressure supercritical CO 2 working fluid in a highly recuperated cycle that captures all emissions by design.

Novel adaptation for existing blast furnaces could reduce steelmaking emissions by 88%; closed-loop carbon recycling

Green Car Congress

This reduction is achieved through a closed-loop carbon recycling system, which could replace 90% of the coke typically used in current blast furnace-basic oxygen furnace systems and produces oxygen as a byproduct. A double perovskite, Ba 2 Ca 0.66 This reacts with the iron ore in the furnace to produce CO 2.

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. All sorts of scenarios have been developed under the assumption that carbon capture actually reduces substantial amounts of carbon.

Rhodium Group estimates US GHG fell 2.1% in 2019, driven by coal decline

Green Car Congress

The Rhodium Group, an independent research provider, estimates that, after a sharp uptick in 2018, US greenhouse gas (GHG) emissions fell by 2.1% This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by a record 18% year-on-year to its lowest level since 1975. Coal-driven decline.

3.8% drop in EU’s greenhouse gas emissions in 2019; transport emissions rise

Green Car Congress

Total greenhouse gas emissions in the European Union (EU) decreased by 3.8% The large decline in emissions, achieved before the COVID-19 crisis, was mainly due to reduced coal use for power generation. below 1990 levels, not accounting for carbon dioxide removals from land use, land-use change and forestry (LULUCF) activities.
