Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

The researchers believe this new type of photoelectrode is not only cheap to produce, but can also be recreated on a larger scale for mass and worldwide use. The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

I think the chemistry we have right now might be the best that’s out there for stationary storage and quite possibly cheap enough to make it in the marketplace, but we have ideas that could lead to huge improvements. So far, we’ve seen no sign of degradation after more than 100 cycles, but commercial applications require thousands of cycles.

BNL Researchers develop low-cost, efficient, non-noble metal electrocatalyst to produce hydrogen from water

Green Car Congress

A team of researchers led by Dr. James Muckerman at the US Department of Energy’s (DOE) Brookhaven National Laboratory (BNL) have developed a new class of high-activity, low-cost, non-noble metal electrocatalyst that generates hydrogen gas from water. Click to enlarge.

Bio-inspired molybdenum sulfide catalyst offers low-cost and efficient photo-electrochemical water splitting to produce hydrogen

Green Car Congress

Progress has so far been limited in part by a lack of cheap catalysts that can speed up the generation of hydrogen and oxygen. “If we can find new ways of rationally designing catalysts, we can speed up the development of new catalytic materials enormously” —Jens Nørskov.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. The low cost of porous melamine means that the material could be deployed widely.

Initial Results of UK EV Driver Study Show Increased Confidence and Low Cost Recharging

Green Car Congress

Collecting real-world analysis of electric vehicles is essential in understanding actual demands and requirements of low carbon vehicles for consumers. The low cost of ‘refuelling’ in relatively short periods of time reinforce this. —Brian Price, lecturer in Engineering Systems and Management at Aston.
