WASHINGTON — Blackstone, the New York-based asset supervisor with practically $1 trillion of investor funds, is transferring quickly into the clean-energy revolution, pushed partly by federal tax incentives that had been sweetened this summer season by the Biden administration and Congress.
However one among its bigger initiatives — via a subsidiary known as Tallgrass Vitality — is drawing protests from environmentalists who argue that Blackstone’s effort in New Mexico won’t do sufficient to fight local weather change, even when it receives tens of thousands and thousands of {dollars} a 12 months in federal subsidies supposed to advertise efforts to deal with world warming.
Tallgrass intends to spend $600 million to rebuild a defunct coal-burning energy plant in northwest New Mexico into one which makes use of pure gasoline transformed into hydrogen to create electrical energy that will likely be despatched to households and companies in 4 states within the area.
The venture can be eligible for a beneficiant tax break — producing about $30 million a 12 months in federal subsidies for its electrical energy era — as a result of the climate-change-causing carbon generated by the plant can be collected after which buried deep underground, in a course of known as sequestration.
The local weather and tax laws handed this summer season by Congress and signed by President Biden, generally known as the Inflation Discount Act, elevated the carbon seize subsidy by 70 %, to $85 per ton of carbon that’s captured and buried.
The New Mexico venture is anticipated to sequester about 380,000 tons of carbon yearly because it creates electrical energy. The regulation additionally created a brand new subsidy for hydrogen-powered electrical vegetation, which means there are two beneficiant tax breaks from which it may possibly select. (It may possibly faucet into solely one among them.)
These federal tax breaks essentially change the economics of hydrogen-based energy initiatives, making them rather more engaging to buyers like Blackstone and its companions, whereas in concept additionally offering advantages to the setting and electrical energy ratepayers.
“It has helped make the venture extra viable,” mentioned Justin Campbell, vp of energy at Tallgrass Vitality.
However the Tallgrass venture, if all goes as deliberate, can be a primary of its sort in the USA: a former coal-burning electrical energy plant transformed into one which burns solely hydrogen to create electrical energy. Building on the venture has not began but, and a Tallgrass official mentioned the corporate was nonetheless evaluating the funds earlier than transferring forward.
Producing that energy requires some difficult steps which have raised questions in regards to the long-term viability of the method.
Rather than coal, Tallgrass would take pure gasoline drilled from the New Mexico space and convert that gasoline into hydrogen via a course of known as methane reforming, which depends on high-pressure steam to separate hydrogen from the gasoline.
The steam reformer additionally removes carbon dioxide, which Tallgrass would acquire after which ship deep underground for everlasting storage, eliminating a lot of the local weather change menace that comes from a coal-burning plant or perhaps a conventional pure gas-burning energy plant.
When the remaining hydrogen is burned to create electrical energy, it generates no carbon dioxide, explaining why the backers of the venture say it is going to be “zero emission” energy.
Emily Kent, a director on the Clear Air Activity Pressure, an environmental group, mentioned hydrogen initiatives fueled with pure gasoline just like the one Blackstone was proposing had been necessary as a result of the electrical energy sector wanted to have dependable, carbon-free energy sources that might ship vitality when wind or solar energy may not be obtainable.
“The priority is that we would have bother assembly hourly and day by day vitality demand across the nation with solely intermittent sources like wind and photo voltaic,” she mentioned, saying the venture is a type of what she calls “clear agency” energy.
The issue with the plan, based on different vitality analysts and environmental engineers, is that the method is extraordinarily inefficient: Utilizing pure gasoline to create hydrogen may be very vitality intensive.
Even the U.S. Division of Vitality notes that “it takes extra vitality to provide hydrogen (by separating it from different parts in molecules) than hydrogen supplies when it’s transformed to helpful vitality.”
Burning hydrogen to create electrical energy generates nitrogen oxide, one other pollutant that may trigger bronchial asthma and different respiratory illnesses. And the method of drilling and transporting pure gasoline to the positioning typically entails the discharge of methane, which is an much more potent reason for local weather change than carbon dioxide.
Making issues worse, mentioned Bruce Robertson, an vitality trade analyst who performed a examine of carbon seize initiatives worldwide, most of them have did not dwell as much as promised carbon removing targets, which means they haven’t achieved the supposed environmental advantages.
“The trade has a historical past of over-promising and under-delivering,” he mentioned, pointing to less-than-anticipated carbon seize at initiatives equivalent to Chevron’s Gorgon venture in Australia, which additionally acquired authorities subsidies however then fell far in need of its carbon removing targets.
All these causes have led some environmental engineers and vitality trade analysts to query why Congress and the Biden administration are providing beneficiant subsidies to so-called blue hydrogen initiatives that depend on pure gasoline to provide electrical energy.
By comparability, inexperienced hydrogen initiatives — which might get much more beneficiant subsidies from the Inflation Discount Act — use electrical energy produced by wind or photo voltaic initiatives to provide the hydrogen wanted to make energy, a extra environmentally pleasant course of.
“Blue hydrogen is essentially a creation of the gasoline trade to attempt to extend the pure gasoline enterprise,” Mr. Robertson mentioned.
Tallgrass Vitality, the truth is, is primarily a pure gasoline pipeline firm, and lots of the greatest backers of the carbon seize know-how, equivalent to Exxon, are oil and gasoline corporations.
A spokeswoman at Blackstone, which has a majority stake in Tallgrass through a fund backed by the federal government of Saudi Arabia, declined to touch upon the venture. Blackstone is run by Stephen A. Schwarzman, a significant Republican donor and help of former President Donald J. Trump.
However executives at Tallgrass mentioned they had been assured they may ship on their guarantees, which embody eradicating at the very least 95 % of the carbon dioxide generated when producing the hydrogen gasoline, a a lot increased carbon seize fee than has been achieved in different initiatives.
The corporate may also work to make sure that it buys its pure gasoline from producers and pipeline corporations that restrict methane leaks, one other main supply of discharges that contribute to local weather change, mentioned Dwayne Phillips, vp of hydrogen at Tallgrass.
The New Mexico plant, operating on hydrogen, would assist be certain that the area had a gradual provide of electrical energy. When different renewable sources of energy had been obtainable, the Tallgrass natural-gas-to-hydrogen plant may create hydrogen for different wants, equivalent to powering vehicles or space factories, a spokesman for Tallgrass mentioned.
The venture has gained reward from Gov. Michelle Lujan Grisham of New Mexico, a Democrat who has been working to show the state into a middle for hydrogen manufacturing.
“New Mexico has what it takes to develop into a world hydrogen hub, furthering our decarbonization and local weather efforts whereas creating high quality jobs for New Mexicans,” she mentioned on the time Tallgrass purchased a 75 % stake in Escalante H2Power, which is overseeing the deliberate conversion of the facility plant.
The expanded federal subsidies include an additional bonus that enables venture builders like Blackstone’s Tallgrass to take the tax break nearly like it’s a federal grant: a so-called direct pay provision that provides the corporate a fee for 5 years’ value of carbon seize credit.
Mr. Campbell, the vp for energy and transmission at Tallgrass, mentioned the first profit can be to restrict future will increase in the price of the facility delivered to households and companies within the West.
“What the tax credit score has finished for us is it permits us to have conversations with native utilities and current them an possibility that’s decarbonized but in addition protects affordability of charges,” he mentioned. “We expect quite a bit about not simply decarbonization, but in addition reliability and affordability.”
