Hope you all had fun with the Energy Post Quiz, published before the Christmas break. Here are the answers. There are ten questions, both entertaining and insightful. The answers could all be found in articles that appeared here during 2021, and we give you the links to them. During 2021 Energy Post had another strong year in terms of number of debates hosted, event attendance, and readership for our articles: our readership grew by … [Read more...]
Energy Post Quiz 2021
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?
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
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
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?
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...]
