Researchers develop new stable artificial photosynthesis device to produce ethylene and hydrogen from sunlight and CO2

Green Car Congress

A research team has developed a new artificial photosynthesis device component with remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels: ethylene and hydrogen. The device produced ethylene and hydrogen with unprecedented selectivity and for more than 24 hours.

An abundant and inexpensive water-splitting photocatalyst with low toxicity active in visible light

Green Car Congress

Researchers at Japan’s National Institute for Materials Science (NIMS) have discovered a new photocatalyst, Sn 3 O 4 , which facilitates the production of hydrogen fuel from water, using sunlight as an energy source. Sn 3 O 4 has great potential as an abundant, cheap, and environmentally benign solar-energy conversion catalyst.

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

As the pandemic continued to grind on, it was actually comforting to know that smart people in the energy sector were working hard to keep the lights on, advance the technology, and improve people’s lives. This time around, though, the emphasis is on “green hydrogen”—that is, hydrogen produced using clean energy such as solar or wind power.

Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

First, it considers the performance of both mature and novel hydrogen production processes, multiple electricity generation pathways and several alternative drivetrains. Li-ion battery specific energy density is presumed to be 150 Wh kg -1 , and fuel cell specific weight is 3 kg kW -1. Second, it is specific to Switzerland.
