It’s lengthy been mentioned that hydrogen is the gasoline of the longer term — and it at all times will likely be. In some elements of the globe, the longer term seems to be right here now, or a minimum of it’s on the foreseeable horizon. Right here in North America, nevertheless, not a lot. In the event you choose the potential for hydrogen as a net-zero vitality supply based mostly on home observations and expertise, you would be forgiven for pondering its potential is proscribed. That’s not the case elsewhere.
Demand projections for hydrogen are exploding in Asia, Australia, and Europe, and the requisite manufacturing capability is on its strategy to being created. A report launched by the Hydrogen Council, in collaboration with McKinsey & Firm, “Hydrogen Insights 2021: A Perspective on Hydrogen Funding, Deployment and Price Competitiveness,” signifies as of early 2021, 228 large-scale hydrogen manufacturing initiatives had been initiated, with 85% of them in these three areas.
In one other report from early 2021, the Hydrogen Council mentioned it was monitoring 680 initiatives valued at an estimated $240 billion, noting the worth of mature initiatives world wide simply six months earlier was $160 billion.
Even with all that projected or soon-to-be-deployed funding, the Worldwide Power Company says we’ll nonetheless want an extra 530 million tons of hydrogen to succeed in a net-zero state of affairs by 2050.
As of 2019, world consumption of hydrogen (all sorts) was 115 million tons, the overwhelming majority of which went to heavy business, together with metal making, petrochemical refining and heating. Transportation of all sorts accounted for lower than 10,000 tons. By 2030, transportation’s share is anticipated to succeed in 1.6 million tons, rising to 66.5 million tons by 2050, and virtually 160 million tons by 2070, in accordance with IEA.
Producing that a lot inexperienced hydrogen will likely be daunting. IEA suggests round 300 metric tons of hydrogen may very well be produced from electrolyzers in 2070 underneath what it calls the Sustainable Improvement Situation. This might require 13,750 terawatt-hours of electrical energy — equal to half of worldwide electrical energy era at present, IEA says. By 2070, electrolyzer capability must rise from 170 megawatts at present to greater than 3,000 gigawatts.
In different phrases, reaching the net-zero targets in 2050 would require a six-fold improve in hydrogen manufacturing over present output.
Why is North America Behind the Curve on Hydrogen?
We right here on this facet of the pond have some catching as much as do with regards to inexperienced hydrogen, which is produced virtually solely via electrolysis. Nearly all of American hydrogen for industrial functions, 11 million tons of it yearly, is produced by steam methane reforming of pure gasoline (SMR) — which after all is a fossil gasoline and thus produces CO2. It’s low cost and plentiful right here, however environmental activists are lifeless set towards its use despite the fact that it’s nonetheless thought of cleaner than even at present’s cleanest diesel engines.
Some SMR sources of hydrogen can reap the benefits of carbon sequestering, which provides price however yields hydrogen with a manufacturing chain that’s mentioned to be 89% cleaner than simply SMR.
There are different sources of renewable (inexperienced) hydrogen, however they’re fairly small in scale at current. For instance, Hyzon was collaborating with RenewH2, a U.S.-based sustainable hydrogen producer, to provide liquid hydrogen generated by biogenic methane gasoline.
That enterprise is up within the air as of this writing whereas Hyzon kinds out its accounting irregularities.
Nikola just lately acquired a stake within the Wabash Valley Assets clear hydrogen challenge in Indiana. The challenge plans to make use of stable waste byproducts similar to petroleum coke mixed with biomass to supply clear and sustainable hydrogen.
Nikola’s long-term imaginative and prescient is to make use of renewable energy (similar to solar energy or hydro) for onsite manufacturing of “inexperienced” hydrogen through electrolysis, but it surely’s now trying to manufacturing hubs and transporting liquified hydrogen to market to enhance the economics.
“We have now at all times deliberate to make use of electrolyzers, and the early days of technique for Nikola was to have on-site manufacturing utilizing electrolysis at fueling stations to take away the price of distribution,” says Pablo Koziner, Nikola’s president, Power and Business. “We haven’t discarded the thought of manufacturing on-site at stations, however we’ll solely do this when the economics lend themselves for that to be the very best answer.
“Because the business matures, we anticipate that pipelines will begin to come into play for hydrogen and that can decrease the distribution prices,” he provides.
Hub-based manufacturing utilizing renewable sources is a method of getting hydrogen to market, however there nonetheless must be accompanying demand. And as demand grows, manufacturing must preserve tempo. That will likely be a tightrope to stroll at some future date. Within the meantime, the push is on to construct out extra electrolyzer capability, each giant and small crops that may serve native and regional markets.
Inexperienced Capability Grows within the Trucking World
Across the globe and right here at dwelling, some very large-scale productions amenities are within the works.
The Worldwide Renewable Power Company just lately revealed an inventory of the 20 largest giga-scale electrolyzer initiatives on the earth. In prime spot was the HyDeal Ambition challenge in Spain. When totally operational in 2030, complete put in solar energy capability is anticipated to succeed in 9.5 GW, with a complete put in electrolyzer capability of seven.4 GW.
The smallest challenge on the High 20 record is the Helios Inexperienced Fuels challenge in Saudi Arabia. When the $5 billion facility is up and working, it’ll combine 4 gigawatts of renewable energy from wind and photo voltaic for a every day output of 650 tons of hydrogen.
Right here at dwelling, Hy Stor Power introduced final October it plans to construct a inexperienced hydrogen manufacturing and storage advanced in Mississippi that may very well be making 110,000 metric tons of inexperienced hydrogen per 12 months by 2025. And in south Texas, development is already underway on a plant that would produce as a lot as 2.5 million tons of renewable hydrogen yearly from 60 GW of wind and photo voltaic. In each instances, hydrogen produced can be saved in underground salt caverns.
These initiatives have already got dedicated buyer bases, but it surely’s affordable to imagine {that a} hydrogen-powered transportation community might develop organically across the websites.
Cummins’ New Energy has a foot within the door on this market too. It just lately began up a 20-megawatt electrolyzer in Bécancour, Quebec, about an hour’s drive east of Montreal, with an output of 8.2 tons of low-carbon hydrogen per day — or almost 3,000 tons yearly. It’s powered by the area’s low cost and environment friendly hydropower electrical grid, yielding hydrogen at a value similar to the value of SMR-produced hydrogen, Cummins says.
“We are able to cool and liquify the hydrogen and economically transport it 500 to 1,000 miles by truck at a really aggressive value,” mentioned Michel Archambault, former business director for hydrogen manufacturing within the Americas for Cummins. He held that place in June when he spoke with a bunch of journalists at a Cummins gathering. His LinkedIn web page reveals he has since left the corporate.
Gas cells powered by compressed hydrogen gasoline supply an extended leash than batteries do, in the meanwhile, however will their projected excessive price restrict uptake?

Archambault mentioned as a result of Cummins’ electrolyzer know-how is a modular answer, it’s scalable based mostly on demand, and will effectively match a behind-the-fence fleet fueling technique. For example, two of Cummins’ Hylyzer-500s on-site might produce as much as 2,000 kilograms per day, sufficient for 65-80 Class 6 vans with 25 to 30 kg at 350 bar stress (5,000 psi).
Options to an on-site electrolyzer embody dropped high-pressure tube trailers, or storage tanks for liquified hydrogen outfitted with compressors. “The consideration of on-site hydrogen manufacturing, gaseous hydrogen supply, or liquid hydrogen supply relies on the house accessible on the fleet fueling web site, dimension of the fleet, and value of electrical energy on the web site,” mentioned Natalie Moya, communications supervisor for Cummins New Energy.
Inexperienced Fleets at Any Price?
Maybe you’ve observed the liberal use of the phrase billion on this story. Transitioning away from fossil fuels goes to be something however low cost. Luckily, traders appear eager on staking a declare on this new gold rush.
It virtually appears trifling to fret about the price of a kilogram of hydrogen, contemplating the price of FCEV vans — mentioned by the American Transportation Analysis Institute to be within the $200,000 to $600,000 vary.
We don’t but know the way that price would evaluate with hydrogen ICE vans. Cummins has hinted that the price of its ICE hydrogen will doubtless be just like the unfold between diesel and pure gasoline vans. Cummins’ basic supervisor for hydrogen engines Jim Nebergall says there’s room for the price of FCEVs and BEVs to return down with scale and know-how enhancements, however they are going to nonetheless be very costly in comparison with an ICE. He says the corporate’s X14H engine has lots going for it proper out of the gate, similar to a lot simpler chassis integration.
“OEMs can have a a lot simpler time placing this engine underneath their hoods,” he says. “It’ll be similar to the to the pure gasoline and diesel variations of the engine, which we’re fairly conversant in.”
He says the gasoline cells use hydrogen extra effectively however notes with the convenience of integration and the decrease price, it could get fleets began on hydrogen far more rapidly. Payback is a special story.
In essentially the most advantageous state of affairs for a gasoline cell, excessive mileage and excessive gasoline price, the payback will likely be about 4 years.
“However in case you don’t run numerous miles or gasoline is affordable, then it’ll take longer to up the distinction,” Nebergall says. “Our modeling reveals it’s anyplace from 4 years to 12 years to make up the distinction, simply due to the effectivity.
“Whereas there’s numerous room for gasoline cells and batteries to return down, we expect the hydrogen ICE can have an ideal begin due to that platform’s maturity and its decrease price.”
It’s slated to hit the streets in 2027. That buys us just a few extra years to get this found out.
