Making Hydrogen direct from seawater using double-membrane electrolysis

May 24, 2023 by David Krause

Can hydrogen be produced from seawater? The standard method requires water to be purified, which is expensive to do and adds complexity to the device. David Krause at the SLAC National Accelerator Laboratory, Stanford University describes new research there that uses electrolysis and a double membrane directly on the seawater to separate out the chloride and isolate the hydrogen and hydroxides. The system operates without generating toxic … [Read more...]

Hydrogen’s innovation pipeline: signals strong ahead of World Hydrogen Summit in Rotterdam, May 9-11, 2023

March 21, 2023 by Ian Shine

The IEA and the European Patents Office have, for the first time, reported on patents filed worldwide to get a measure of the innovations we’re seeing in the hydrogen sector, summarised here by Ian Shine. Overall, Europe and Japan are leading. Although the U.S. is a close third, with 20% of the total, their filings have declined compared to the previous decade. The fastest growth is in China (15.2%) and South Korea (12.2%). There has been a … [Read more...]

Energy Post Quiz 2021

December 17, 2021 by Matthew James

Energy Post has had another strong year in terms of number of debates hosted, readership growth and event attendance. Our readership has grown by 17.16% year on year. We hosted 14 panel discussions (including 3 for ECECP with an average of 20 panellists from all corners of the globe). Together we've reached hundreds of thousands with our event packages. Our thanks to all our authors. Now, with all those parties cancelled due to Covid you have … [Read more...]

Hydrogen production in 2050: how much water will 74EJ need?

July 22, 2021 by Herib Blanco

There’s no point ramping up hydrogen if other resource constraints are going to bring it to a halt. Here, Herib Blanco at IRENA summarises their research into how much water will be needed in the production of hydrogen through electrolysis (i.e. from water) and the costs involved. A wide range of analyses have been reviewed to calculate the amount of water used during the hydrogen production, and by the energy source used to power it (renewables … [Read more...]

Clean Hydrogen from water electrolysis: research into catalysts to meet global targets

May 27, 2021 by Glennda Chui

The full potential of the new hydrogen economy will depend on producing enough clean hydrogen from water electrolysis which uses precious metals. But, as Glennda Chui at SLAC (Stanford University & DoE) explains, there aren’t enough precious metals in the world to get to the scale we need. And their cost is so high the clean hydrogen they generate could never compete with hydrogen derived from fossil fuels. Over 95% of hydrogen produced today … [Read more...]

Hydrogen electrolysis: cheap, abundant Cobalt Phosphide can replace Platinum

October 24, 2019 by Stanford University

Platinum and iridium are the preferred catalysts for producing hydrogen through electrolysis at scale. But they are expensive and rare, offering serious bottlenecks in hydrogen’s plans to replace gas worldwide. Now researchers at the U.S. Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have shown for the first time that cobalt phosphide can do the same job in the harsh environment of a commercial device: high … [Read more...]

The Clean Hydrogen revolution: how, by whom, when?

May 22, 2019 by Noé van Hulst

Hydrogen rivals oil and gas for storage and hard-to-decarbonise sectors (industry, heavy and long distance transport). But it isn’t all carbon free. “Grey” hydrogen – the cheapest at €1.50/kilo - is made from gas. “Blue” hydrogen depends on the fortunes of carbon capture technology. “Green” hydrogen is CO2 free, but needs further cost reductions in the green electricity used in the electrolysis process. NoĂ© van Hulst, at the Netherland’s Ministry … [Read more...]
