EIA: US energy-related CO2 fell by 2.8% in 2019, slightly below 2017 levels

Green Car Congress

In 2019, CO 2 emissions from petroleum fuels—nearly half of which are associated with motor gasoline consumption—fell by 0.8%, and CO 2 emissions from the use of natural gas increased by 3.3%. Nearly all of the change in CO 2 emissions in 2019 arose in the electric power sector.

New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

The work, presented in a paper in Proceedings of the National Academy of Sciences (PNAS), offers a unique, highly efficient, and inexpensive route for solar fuels synthesis. The solar-powered catalyst is made from abundant materials and works in a configuration that could be mass-produced. 1 under air mass 1.5 —Zhou et al.

IEA: global CO2 emissions rebounded to their highest level in history in 2021; largely driven by China

Green Car Congress

The recovery of energy demand in 2021 was compounded by adverse weather and energy market conditions—notably the spikes in natural gas prices—which led to more coal being burned despite renewable power generation registering its largest growth to date. CO 2 emissions from natural gas rebounded well above their 2019 levels to 7.5

Prometheus CEO outlines tech advances that could make CO2-to-fuels renewable gasoline and jet price-competitive with fossil fuels

Green Car Congress

Recent breakthroughs in separations and catalysis, along with long-trend reductions in solar and wind electricity costs, have significantly increased the potential for cost-competitive renewable fuels from direct air capture (DAC) of CO 2. TW of combined solar and wind capacity for the United States alone will be required.

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. unusually high electrical conductivity and Raman spectra of these materials demonstrated in the linked Data in Brief paper are that of multi-walled carbon nanotubes, and are due to the morphology as demonstrated by TEM.

GWU team develops cost-effective solar process to produce lime for cement without CO2 emission

Green Car Congress

Conventional thermal decomposition production of lime (left) versus STEP direct solar conversion of calcium carbonate to calcium oxide (right). Conducive to our new solar process, electrolysis of molten carbonates forms oxides, which precipitate as calcium oxide when mixed with calcium carbonate. Click to enlarge. —Licht et al.

IEA: global energy demand rose by 2.3% in 2018, fastest pace in the last decade; CO2 emissions up 1.7%

Green Car Congress

Natural gas emerged as the fuel of choice, posting the biggest gains and accounting for 45% of the rise in energy consumption. Gas demand growth was especially strong in the United States and China. Solar and wind generation grew at double-digit pace, with solar alone increasing by 31%. Energy demand worldwide grew by 2.3%
