Study: air pollution caused 1.1M deaths across Africa in 2019, toll from outdoor pollution rising

Green Car Congress

Air pollution was responsible for 1.1 Air pollution was responsible for 1.1 Deaths attributable to household air pollution and ambient particulate matter (PM 2.5 ) air pollution in Ethiopia, Ghana, Rwanda, and overall in Africa, 1990–2019. The most disturbing finding was the increase in deaths from ambient air pollution.

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. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution. A study by Mark Z.

Opinion: Reinventing fuel-based power for a more secure and resilient grid

Green Car Congress

It is, however, a challenge that is being made all the greater as we continue to decentralize power generation with more distributed, variable and inflexible sources, such as wind and solar. Increasingly, wind and solar are replacing fossil fuels as our principle source of energy.

U of Melbourne team demonstrates direct hydrogen production from air; direct air electrolysis (DAE)

Green Car Congress

Researchers at the University of Melbourne (Australia) have demonstrated a method of direct hydrogen production from air— in situ capture of freshwater from the atmosphere using hygroscopic electrolyte and subsequent electrolysis powered by solar or wind with a current density up to 574 mA cm ?2.

Blue World Technologies launches next-generation methanol fuel cell system for stationary power generation

Green Car Congress

On the market for smaller gensets, we can make a significant difference now bringing down CO 2 emissions and air pollution. The system can be installed as a hybrid solution combined with renewable energy sources such as solar cells or wind turbines. So, this is where we start, one generator at a time.

ARPA-E to award up to $5M to investigate extracting rare earth and other critical minerals from macroalgae

Green Car Congress

Seaweeds accumulate trace metals in such an efficient way that this process is sometimes used to clean up polluted harbors. It would be transformative if we could harness that capability to harvest the critical rare earths we need for a net-zero economy in a low-impact way using this natural ability.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The difference helps explain how much industrial pollution influences clouds. NASA Earth Observatory.
