The Gulf is already a major producer and consumer of hydrogen, mainly for fertilisers and specialty chemicals. Like most hydrogen produced globally, it is the âgreyâ kind made from hydrocarbons. But the regionâs low renewable power costs and abundance of land give it the key components for the industrial scale production of green hydrogen. So in July, the Saudi model city of Neom (Neom means ânew futureâ) and ACWA Power signed a joint venture … [Read more...]
Who will be the Hydrogen superpower? The EU or China
Implicit in the EUâs plans, announced in July, to be the worldâs Hydrogen leader is that this technology will have others competing for the top spot too. When EU nations ramped up their solar PV sector in the 2000s they couldnât survive the arrival and rapid expansion of Chinese production. Will EU Hydrogen meet the same fate? Sören Amelang at CLEW speaks to a wide range of experts to try to answer this vital question from all the relevant … [Read more...]

Register now to join us at the event next Wednesday at 12.45 CEST on Zoom to hear direct from the European Commission's Dr. Florian Ermacora, Future Energy System expert Prof. dr. Ad van Wijk, Giulia Branzi - Head of Regulation at event partner SNAM and trading specialist Marcel Steinbach of BDEW. Here, to set the scene, Gökçe … [Read more...]
Energy conversion for Hydrogen cars is only half that for BEVs
Though Toyota may be a big fan, hydrogen cars have a problem. Energy must move from wire to gas to wire to power the car. There are always significant losses when the energy vector changes. For Battery Electric Vehicles (BEV) the energy stays on wires all the way to the car. Tom Baxter at the University of Aberdeen looks at the losses at each stage to show that for hydrogen only 38% of the original electricity gets used. For BEVs itâs 80%. … [Read more...]
An EU Hydrogen strategy: from industry feedstock to energy vector
The bravest recovery strategies will invest robustly in new yet-to-take-off clean energy technologies. If you are going to have to spend hundreds of billions to revive your economy isnât it better to replace the old with the new rather than prop up what youâll have to abandon soon anyway? In anticipation of that happening, new technologies are lining up. Here, CĂ©dric Philibert at the IFRI Centre for Energy & Climate summarises their detailed … [Read more...]
Two new designs, GSR and MA-ATR, to make âblueâ Hydrogen cheaper
Whatâs the best way to make clean hydrogen? Steam Methane Reforming (SMR) is the most common and cheapest way of producing hydrogen, but it also produces CO2 emissions. Capturing that CO2 is complex and costly. Schalk Cloete presents research on two new designs for âblueâ hydrogen (blue = derived from natural gas/coal with carbon capture/CCS). He describes in detail Gas Switching Reforming (GSR) and Membrane-Assisted Autothermal Reforming … [Read more...]
Gas Switching Reforming: making Hydrogen to balance variable Wind, Solar
What is the best technology to balance the variable output of wind and solar? When there is little wind and sun the plant must produce power to compensate. When thereâs too much wind and sun it must utilise that excess power. In other words, given the high capital cost of the new balancing technology it must do both profitably enough to cover the time sitting idle. A paper co-authored by Schalk Cloete looks at Gas Switching Reforming (GSR). The … [Read more...]
CCUS, nuclear, industrial heat, hydrogen, smart grids: âlarge unitâ innovation needs more support
How do we accelerate innovation across all technologies? Simon Bennett at the IEA breaks down the task into âsmall unitâ and âlarge unitâ challenges. The first is easier and moves faster. Thanks to their small size and unit cost, heat pumps, EVs and solar panels benefit from mass production, mass deployment (100,000 to 100m units/year globally) and large customer markets with fierce competition. They can also easily leverage other fast-evolving … [Read more...]
Hydrogenâs future: reducing costs, finding markets
Although 100Mt/year of hydrogen is produced globally and at scale, itâs overwhelmingly for the chemical industry. So thereâs a long way to go for it to play a role in the energy transition. Itâs not even clear whether hydrogen will be best used directly as a power source or through further conversion into other powerfuels. That's why Dolf Gielen and Emanuele Taibi at IRENA are scoping out the challenges of reducing production costs and finding … [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 hydrogenâs plans to replace gas worldwide. Now researchers at the U.S. Department of Energyâs 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...]
Hydrogen Fuel Cell trucks can decarbonise heavy transport
Patrick Molloy at Rocky Mountain Institute runs through the pros and cons of hydrogen fuel cell vehicles (FCEVs). The big pluses are that hydrogen has an energy density of around 120 MJ/kg, almost three times more than diesel or gasoline. Half the energy generated by an internal combustion engine is wasted as heat, whereas electric drivetrains used by FCEVs only lose 10%. Nikola Motors, a U.S. maker of hydrogen trucks, claims its vehicles can get … [Read more...]
U.S. nuclear plants to produce carbon-free hydrogen
Nuclear is under severe price pressure from renewables now, as well as gas.But rather than throw the decades of investment and knowledge away, the U.S. Department of Energy is launching three first-of-a-kind projects designed to improve the long-term economic competitiveness of the nuclear power industry. Three commercial electric utilities and Idaho National Laboratory have been chosen to adapt plants to make hydrogen by electrolysis, 100% … [Read more...]
âHard-to-abateâ sectors need Hydrogen. But only 4% is âgreenâ
40% of global greenhouse gas emissions come from âhard-to-abateâ industry sectors like industrial processing and transport. Electrification wonât be enough. They also need hydrogen, argue Patrick Molloy and Leeann Baronett at Rocky Mountain Institute. Hydrogen production is already well established and growing. But itâs mainly for the chemical industry, which never meant it to be âgreenâ: sure enough, only 4% of current hydrogen production is … [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 isnât all carbon free. âGreyâ hydrogen â the cheapest at âŹ1.50/kilo - is made from gas. âBlueâ hydrogen depends on the fortunes of carbon capture technology. âGreenâ hydrogen is CO2 free, but needs further cost reductions in the green electricity used in the electrolysis process. NoĂ© van Hulst, at the Netherlandâs Ministry … [Read more...]
