UCLA team proposes non-photosynthetic biological conversion of CO2

Green Car Congress

Most of us naturally associate biological CO 2 conversion with photosynthesis in plants and algae. Furthermore, the maximum efficiency of solar energy conversion by photosynthesis is 5%, while typical solar panel efficiency reaches 20%. an and Park (2020) “Light-Independent Biological Conversion of CO 2 ,” Joule doi: 10.1016/ j.joule.2020.08.007.

Three-part catalyst study advances conversion of CO2 to ethanol

Green Car Congress

The efficient conversion of carbon dioxide, a major air pollutant, into ethanol or higher alcohols is a big challenge in heterogeneous catalysis, generating great interest in both basic scientific research and commercial applications. The key to this is the well-tuned interplay between the cesium, copper, and zinc oxide sites.

New process uses localized surface plasmons for room-temperature conversion of CO2 to CO

Green Car Congress

The conversion normally requires significant amounts of energy in the form of high heat—a temperature of at least 700 ?C, An array of light beams impinging upon the grid would activate the LSPs. An array of light beams impinging upon the grid would activate the LSPs.

Light-powered nano-bio hybrid organisms consume CO2, create plastics and fuels

Green Car Congress

By using light-activated quantum dots to fire particular enzymes within microbial cells, the researchers were able to create “living factories” that eat CO 2 and convert it into products such as biodegradable plastic, gasoline, ammonia and biodiesel. Therefore, these resting cells function as nano-microbial factories powered by light.

Carsbut not light trucksare driven less during the pandemic

Green Car Congress

Therefore, it is not surprising that in 2020, the first year of the pandemic, the annual miles driven per car or light truck (SUV, pickup truck, or van) decreased substantially. Of more interest is the new finding that this reduction was entirely due to a reduced use of cars as opposed to light trucks. Cars and light trucks.

Rice team develops plasmonic photocatalyst for one-step light-driven conversion of H2S to hydrogen and sulfur

Green Car Congress

An illustration of the light-powered, one-step remediation process for hydrogen sulfide gas made possible by a gold photocatalyst created at Rice University. Each island was a gold nanoparticle about 10 billionths of a meter across that would interact strongly with a specific wavelength of visible light. —Naomi Halas.

HYVIA unveils two new hydrogen light commercial vehicle prototypes

Green Car Congress

Following on the reveal of Renault Master Van H2-TECH last month ( earlier post ), HYVIA has unveiled two new Hydrogen Light Commercial Vehicles prototypes with zero CO 2 tailpipe emissions, increased range, and 5-minute refueling time. This vehicle allows a range of about 250 km and offers great potential for tailor-made conversions.
