New catalysts enable photocatalytic version of water gas shift reaction for H2 production

Green Car Congress

Politécnica de Valencia (Spain) have found that noble metal nanoparticles supported on titanium dioxide or cerium dioxide can catalyze the industrially important water gas shift (WGS) reaction for hydrogen production at ambient temperatures using visible light irradiation. —Sastre et al.

Researchers develop microwave-driven, energy-efficient process for magnesium production

Green Car Congress

The hot reaction zone is either gas-fired, coal-fired, or electrically heated in a furnace; the condensing section is water-cooled. In this study, we have investigated a new Pidgeon process, using microwaves instead of coal as the heat source, for producing Mg with lower energy inputs and a decrease in greenhouse gas emissions.

Green Hydrogen Cars: How They are Different?

Get Electric Vehicle

To put it another way, instead of splitting water into hydrogen and oxygen with electricity, these two components are joined to make water and electricity The electricity is then utilized to power the car’s drive train, leaving just water as a waste product. Green Hydrogen & Its Production.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Transaction Costs.

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

Second, conventional coal and nuclear plants are being retired for economic and policy reasons, removing stable sources from the grid. The brown line shows the uncoordinated load from 1,000 electric water heaters for reference. Here’s what flexibility means when it comes to operating, say, a residential electric water heater.

Kyoto team develops two-stage process for direct liquefaction of low-rank coal and biomass under mild conditions

Green Car Congress

Researchers at Kyoto University in Japan have proposed a novel two-stage process to convert low-rank coals or biomass wastes under mild conditions to high-quality liquid fuel. Also, liquefying high-oxygen content low-ranking coal and biomass also consumes more hydrogen and produces more CO 2 , significantly reducing process efficiency.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. record levels , mostly because of the coal, oil, and natural gas that gets burned for electricity, heat, and transportation. This second layer of the atmosphere is serene and mostly void of life.
