_VoicesRussia-Ukraine War Is Another Reason to Break Free of Dirty Steel, but U.S. Companies Still Chase Profits Over Green Future

The war in Ukraine has broken the pig iron supply chain, creating an opportunity for the U.S. to lead the transition to green steel production.

The Azovstal Steel and Iron Works facility operated by Metinvest Group in Mariupol, Ukraine, on Jan. 15, 2022.

In 2021, Russia and Ukraine supplied over 60 percent of the pig iron imported by the United States. Pig iron, made from iron ore, is the raw material used in most steel production, and the war has fueled pig iron panic-buying on the part of U.S. steel producers. Since the February 24 invasion, U.S. steel prices have surged by 50 percent. A December U.S. Chamber of Commerce survey of the commercial construction industry found that the high price of steel combined with product shortages could stall the post-pandemic commercial construction recovery.

This disruption in the steel supply will impact everything from the auto industry to the rate of inflation. It could also have a profoundly negative effect on renewable energy, a rapidly growing sector in the U.S., which is already hitting major supply chain constraints.

In February, the U.S. Bureau of Ocean Energy Management auction for the rights to build wind turbines off the shores of New York and New Jersey brought in a record-setting $4.37 billion in high bids. Ocean wind turbines require large amounts of steel, and initially it was proposed that the winning bidders must use U.S.-made steel, as required in the Buy American Act. However, the New York agency overseeing the auction determined that the requirement should not apply: Using U.S.-made steel would be too expensive, in part because the United States does not produce enough of the types of steel required for today’s massive wind turbines.

The United States is not able to produce the steel needed to build the clean energy infrastructure required to transition off of fossil fuels to zero-carbon energy sources. At the same time, the U.S. steel industry has no current plans to build new, clean-steel production facilities — which means wind turbines and the rest of the clean energy infrastructure will be built with dirty steel. In November 2021, Lourenco Goncalves, the CEO of leading U.S. steel company Cleveland-Cliffs, said his company’s coal-fueled blast furnaces were “here to stay.”

The global steel industry accounts for 8 percent of carbon dioxide emissions and consumes approximately 15 percent of the world’s coal. By far the most emissions-intensive part of the steel production process is making pig iron. U.S. steelmakers claim to be the cleanest in the world, but that claim does not take into account the emissions that are simply being outsourced to countries like Russia and Ukraine along with the production of pig iron.

The solution to the dirty pig iron problem is not to build more coal-based, pig-iron production facilities in America, but to use green hydrogen — which can be produced emissions-free using renewable energy — to turn iron ore into direct reduced iron (also known as sponge iron). Green hydrogen (in contrast to “gray hydrogen” made with natural gas) is derived from water, split into oxygen and hydrogen by units called electrolyzers.

A worker monitors the zinc galvanized steel on the rolling plant that will in the future harness hydrogen instead of coal, on the production line at the Salzgitter AG steel plant in Salzgitter, Germany, on July 13, 2020.

Energy costs will also drive this transition. The cost of renewable electricity used in green hydrogen technology continues to fall while the cost of coking coal — the kind of coal used to make pig iron — is at an all-time high. In January, management consulting firm McKinsey Co. suggested that these higher prices could hasten the transition to green hydrogen replacing coal in steel production noting that the high coking coal prices “could become the norm rather than the exception.”

Replacing dirty pig iron imports with clean sponge iron production directly supports the existing U.S. steel industry, creating new steel industry jobs and protecting existing ones. Overall, it is estimated that transitioning to a net-zero emission economy would create 20 million jobs, including many well-paying jobs in steel and auto manufacturing, construction, and renewable power plants.

Yet, major U.S. steel producers have no plans to invest in clean steel production, nor do they have an incentive to in the current high-price and high-profit environment. As with the oil and gas industry, U.S. steel producers profit from high-priced steel. The industry is unlikely to change without an incentive, so the U.S. elected officials and policy makers must create an industrial policy to make it happen.

The steel industry’s carbon emissions have historically been considered “hard to abate.” That is no longer true. The United States has the opportunity to lead the transition from coal-fired blast furnaces to hydrogen-fueled sponge iron production. Without it, we will be unable to complete the transition to a clean energy future.
