Metallic nanostructures with strong light confinement can triple the efficiency of solar-based hydrogen generation

Green Car Congress

Researchers led by a team from KAUST have found a more sustainable route to hydrogen fuel production using chaotic, light-trapping materials that mimic natural photosynthetic water splitting. The authors designed these to achieve broadband strong light confinement at the metal interface across the entire solar spectrum.

Study finds anthropogenic PM and dust undercutting global solar energy production

Green Car Congress

According to a new study led by a team at Duke University, airborne particulate matter and dust are cutting solar photovoltaic energy output by more than 25% in certain parts of the world, with roughly equal contributions from ambient PM and PM deposited on photovoltaic surfaces.

New mesocrystal photocatalyst enhances light-driven hydrogen production

Green Car Congress

When light is applied to photocatalysts, electrons and holes are produced on the surface of the catalyst; hydrogen is obtained when these electrons reduce the hydrogen ions in water. Using these findings, the research group plans to apply mesocrystal technology to realizing the super-efficient production of hydrogen from solar energy.

Generating Power on Earth From the Coldness of Deep Space

Cars That Think

On the rooftop of a quiet building, a set of panels cools the rooms within and keeps the lights on, removing heat and generating electricity using the coldness of the sky. As the technology improves, we see it enabling solar panels that work at night as well as day, powering remote sensors. It’s a summer night.

IU team creates efficient nanographene-Re electro- and photo-catalyst for efficient reduction of CO2 to CO

Green Car Congress

In addition, the complex can absorb a significant spectrum of visible light to photo-catalyze the chemical transformation without the need for a photo-sensitizer. But these molecules can use only a tiny sliver of the light in sunlight, primarily in the ultraviolet range, which is invisible to the naked eye. Click to enlarge.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. The proposal calls for what’s known as “solar geoengineering”: cooling the planet by deflecting sunlight that would otherwise strike the planet. cancel the launch. “The

Volvo Trucks SuperTruck demonstrator improves freight efficiency by 88%, fuel efficiency by 70%

Green Car Congress

From the top-of-cab solar panels powering its battery and interior lights, to its ultra-light aluminum frame and highly advanced 425 horsepower 11-liter proprietary engine, the SuperTruck concept vehicle allowed Volvo engineers to push the boundaries of heavy truck efficiency. Not every idea made it to the concept vehicle.
