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.

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

Green Car Congress

in 2019, but power sector CO 2 emissions fell by even more (-8.2%), largely because of increases from renewable sources such as wind and solar. Because sources such as wind and solar have no fuel costs, when available, they are the first sources dispatched to meet electricity demand.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

This assessment provides an evaluation of black-carbon climate forcing that is comprehensive in its inclusion of all known and relevant processes and that is quantitative in providing best estimates and uncertainties of the main forcing terms: direct solar absorption, influence on liquid, mixed-phase, and ice clouds, and deposition on snow and ice.

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.

Audi aims to reduce CO2 emissions by 30% over the vehicle lifecycle by 2025

Green Car Congress

In the long term, Audi is pursuing the vision of CO2-neutral mobility and aims to be climate-neutral throughout the company on balance by 2050. Audi opened its electric initiative with the introduction of e-tron, which has been available at dealerships since March. The solar-energy park will produce more than 9.5

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

Noting the references in scientific and policy literature to the need for fast-action mitigation to help avoid DAI and abrupt climate changes, the authors define “fast-action” to include regulatory measures that can begin within 2–3 years, be substantially implemented in 5–10 years, and produce a climate response within decades.

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

Green Car Congress

The global CO 2 emissions and energy demand numbers are based on the IEA’s detailed region-by-region and fuel-by-fuel analysis, drawing on the latest official national data and publicly available energy, economic and weather data. The use of coal for electricity generation in 2021 was intensified by record high natural gas prices.
