For grid-scale energy storage, the search is on for durable batteries made from low-cost materials. Aqueous zinc-iron batteries are one suggestion, where storage is though the reversible plating and stripping of zinc at the anode. One of the problems associated with this chemistry (dendrite growth is another) is hydrogen gas generation from parasitic side-reactions that decompose water – which gradually ...
Japan’s National Institute for Materials Science (NIMS) and the Tokyo University of Science have created a solid-state electric double layer neuromorphic transistor, claiming it to be the fastest yet, and proving its computational ability by training it to convert waveforms. “The team measured the speed at which the transistor operates by applying pulsed voltage to it, and found that it ...
The worst thing in tech is investing in a technology just as it gets overtaken by a better one. Investing in bipolar when MOS was the coming technology, investing in NMOS when CMOS was gaining traction and investing in Mercury Communications – which started setting up phone boxes in the UK in 1986 and stopped in 1995 when it realised ...
Hyundai has shown off this hydrogen fuel cell powered truck at a motor show in the US.
The world’s fastest hydrogen sensor, is being claimed by Chalmers University in Sweden, which can detect 0.1% hydrogen in air in less than a second. It consists of millions of palladium-gold alloy nano-particles – a material which is known for its sponge-like ability to absorb large amounts of hydrogen. The plasmon phenomenon then causes the sensor to change colour when the ...
ULEMCo announces plans to launch a zero emission 50 kW (KVA) generator
A hydrogen fuel cell has been unveiled in Orkney, part of the Surf 'n' Turf hydrogen community energy project, led by the charity Community Energy Scotland
Intelligent Energy of Loughborough has signed a letter of intent to develop hydrogen fuel cells for “a major drone manufacturer”, said Intelligent. “The deal will see the two companies work together in the first quarter of 2016 to develop technological solutions to increase drone flight time. The goal is for the deal to lead to a formal commercial arrangement for the ...
Apparently, tungsten diselenide can enable sunlight to split water into hydrogen and oxygen without the intervention of a photovoltaic cell and electrolysis. And researchers at the Swiss Ecole Polytechnique Fédérale De Lausanne have found a cheap way to integrate WSe2 into a solar cell that gives off hydrogen when presented with water. “Past studies have shown that this material has ...
Researchers at Caltech’s Joint Center for Artificial Photosynthesis (JCAP) are mimicing photosynthesis using semiconductors to make hydrogen and oxygen from water and carbon dioxide. Their artificial leaf consists of a photoanode, a photocathode and a membrane. Light oxidises water molecules to generate oxygen gas, protons, and electrons on the photoanode, while the photocathode recombines the protons and electrons to form ...
