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 it’s 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 isn’t it better to replace the old with the new rather than prop up what you’ll 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 “blue” Hydrogen cheaper
What’s 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 “blue” 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 there’s 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: “large unit” innovation needs more support
How do we accelerate innovation across all technologies? Simon Bennett at the IEA breaks down the task into “small unit” and “large unit” 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...]
Hydrogen’s future: reducing costs, finding markets
Although 100Mt/year of hydrogen is produced globally and at scale, it’s overwhelmingly for the chemical industry. So there’s a long way to go for it to play a role in the energy transition. It’s 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 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...]
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...]
“Hard-to-abate” sectors need Hydrogen. But only 4% is “green”
40% of global greenhouse gas emissions come from “hard-to-abate” industry sectors like industrial processing and transport. Electrification won’t 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 it’s mainly for the chemical industry, which never meant it to be “green”: 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 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...]
50% Hydrogen for Europe: a manifesto
Electricity has well known limitations, mainly for bulk and long-range transport, industrial processes requiring high temperature heat, and the chemicals industry. To entirely replace fossil fuels we need hydrogen, say Frank Wouters and Prof. Dr. Ad van Wijk. It has an energy density comparable to hydrocarbons. There's more: Europe’s electric grid can’t cope with 100% electrification, yet hydrogen would use the existing gas pipe networks. The … [Read more...]
Hydrogen round-up: “fuel cells will replace diesel engines within 10 years”
As the focus moves from decarbonising the electricity sector to embrace transportation and heating, slowly but surely, hydrogen is starting to play a more important role. The gas has a number of advantages over electricity, including its flexibility and the fact that it can provide energy storage for long periods of time, unlike electricity. It can use the existing gas network if it is used for heating, and it is more appropriate than electricity … [Read more...]
