Speak about altering instances. An outdated gasification plant in West Terre Haute, Indiana is getting a brand new life. It is going to use petroleum coke and biomass to supply hydrogen for energy. It is going to additionally seize and sequester the ensuing CO2. Simply how practical is that this pursuit and simply how clear is the method?
The builders say that it’s viable. The hydrogen can be separated and the ensuing power is anticipated to be offered to energy turbines and chemical makers. Utilizing a proprietary course of, the CO2 can be captured and buried. It’s a value efficient endeavor, they add, as a result of it’s repurposing an current asset. It has additionally acquired each federal funding and federal tax credit.
“For all of these causes this can be a clear power challenge that’s more likely to transfer ahead,” says Beth Carter, senior enterprise supervisor for clear hydrogen at Honeywell, in a Zoom dialog with this reporter. “These tasks are commercially out there at the moment. The power transition is just not one thing that may occur in a decade or two. We’re displaying the world it’s occurring now and that it is crucial.”
It’s a twin operation between Wabash Valley Resources LLC and Honeywell UOP applied sciences to seize and sequester as much as 1.65 million tons of CO2 a 12 months. Whereas it acquired funding from the Division of Vitality’s “Carbon Storage Program,” the businesses mentioned that that is small proportion of the general $600 million value. Meantime, the conversion of the gasification plant acquired began in 2020 and the builders count on the reworked facility to generate 300 megawatts of electrical energy with net-zero CO2 emissions in 2024.

The facelift is an element of a bigger effort to maneuver into the hydrogen period. The Fuel Cell and Hydrogen Energy Association estimates that the hydrogen economic system can generate revenues of $140 billion per 12 months whereas additionally creating 700,000 U.S. jobs by 2030. At projected development charges, these projections could possibly be $750 billion per 12 months in income and three.4 million jobs by 2050.
Zeroing In On Value
And superior and reworked plant might scrub the mercury, nitrogen oxide, and sulfur dioxide earlier than it could separate the remaining byproducts: carbon dioxide, carbon monoxide, and hydrogen, which could possibly be used to run every thing from automobiles to energy vegetation to ammonia manufacturing. The Boundary Dam in Estevan, Saskatchewan, Canada, for instance, was the world’s first business carbon seize challenge. As for Honeywell, it says that its expertise can take away nearly all the CO2 and completely retailer it in porous rocks within the Illinois Basin.
Globally, 17 large-scale carbon seize and storage tasks are in operation, says the Global CCS Institute. Extra at the moment are beneath development. Altogether, these ventures would seize about 40 million tons a 12 months of CO2. The present ones are catching a pittance of the general heat-trapping emissions. Nonetheless, at the least 6 billion metric tons of CO2 must be captured by 2050 to maintain temperatures consistent with the Paris local weather accord, provides the International Energy Agency.
Statoil, for instance, is putting 1 million tons of CO2 per 12 months right into a saline aquifer deep within the North Sea to boost oil restoration. Meantime, ConocoPhillips
“The combination of biomass (corn stover) permits us to be net-zero on a lifecycle foundation,” says Dan Williams, managing director for the Wabash Valley Assets in Terre Haute, in the course of the Zoom name. “It must be replicated,” he provides, if the nation is to fulfill its CO2 discount targets. He helps the usage of “petcoke” derived from oil refining as a feedstock, noting that it’s usually disposed of as a waste product however that it’ll now develop into a part of the “clear power” cycle.
Little doubt, the critics will take a whack at this challenge. For starters, they are saying that the assets are finest plowed into growing renewable power assets. Furthermore, the IEA Clean Coal Center says that capturing and storing CO2 requires large quantities of power. That may develop into cost-prohibitive and may trigger the cost of electricity to increase by as much as 80%.
On the similar time, they are saying that producing hydrogen from fossil fuels is just too soiled. As an alternative of utilizing such “gray hydrogen,” the eye must be on “inexperienced hydrogen” created from wind and photo voltaic — a course of that makes use of electrolyzers to separate aside the hydrogen and oxygen from the water the place it’s discovered.
The Studying Curve
Notably, 70 million tons of hydrogen are created annually: extremely, 98% of that manufacturing comes from utilizing carbon-intensive sources. Renewables, in distinction, are limitless and free — a robust incentive to leap to “inexperienced hydrogen.” Importantly, if fossil fuels are used because the feedstock to create hydrogen and if the CO2 emissions are captured and buried, it’s known as “blue hydrogen” — the kind of plant envisioned by Wabash Valley Assets.
Is there a job for blue hydrogen? “The one position I see is that it kicks the can down the road. It perpetuates the lie,” says Andrew Forrest, the founding father of Australia’s Fortescue Metals Group, throughout a current webinar.
The International Renewable Energy Agency says that power losses happen when hydrogen is produced and transported: as a lot as 70% of the power content material could get misplaced, though that determine is much less consequential if the hydrogen is created from solar energy that’s considerable and free. The company concludes that per unit of power, hydrogen provide prices at the moment are 1.5 instances to five instances these of pure gasoline.
It provides that the learning curve linked to creating hydrogen is steep but worth it — regardless of the gasoline that’s used. That’s as a result of it’s all serving to to increase the infrastructure that may carry the hydrogen to the place it’s consumed. That can scale back the necessity for brand new infrastructure funding, accelerating the transition from “gray hydrogen” to “inexperienced hydrogen.”
Take the Los Angeles Department of Water and Power, which can purchase energy from the so-called Intermountain Power Project in Utah that may generate inexperienced hydrogen from wind and photo voltaic: the plant will convert from a coal to a natural-gas combined-cycle facility that may additionally burn hydrogen as a gasoline. By 2025, 30% of the electrical energy will come from inexperienced hydrogen, and by 2045, all of it’ll.
Furthermore, a salt dome situated on-site will retailer the hydrogen. When that gasoline is required, it may be accessed whereas the electrical energy is transported to Los Angeles by way of the prevailing transmission infrastructure.
As for Wabash Valley Assets, “In Indiana, state laws has been handed supporting this challenge,” says Williams. “Indiana doesn’t have numerous wind and photo voltaic and the sort of challenge is necessary.”
Whereas carbon seize and sequestration is proving to be each elusive and costly, the truth is that coal and pure gasoline make up 58% of the U.S. electrical energy era pie. Assembly our local weather targets necessitates the isolation of CO2 and the scaling up of inexperienced hydrogen manufacturing. That can come, although, with a excessive price ticket — a price that would repay if the applied sciences advance and start producing vital outcomes.
