In the local weather world, hydrogen is probably going to be the final multi-tool. It might maybe presumably well also additionally be historic in fuel cells or combustion engines and is mostly called the Swiss Military knife for cleaning up emissions. I’ve written about efforts to make use of hydrogen in steelmaking, automobiles, and aviation, factual to title just a few. And a fresh narrative for our most unusual print divulge explores the probability of hydrogen trains.

Hydrogen will likely be many tools in one, but some experts argue that it can’t do it all, and some uses may in fact be distractions from real progress on emissions. So let’s dig into where we might expect to see hydrogen used and where it could deliver the largest emissions cuts.

Hydrogen might play a role in cleaning up nearly every sector of the economy—in theory. The reality today is that hydrogen is more of a local climate challenge than a solution.

Most hydrogen is used in oil refining, chemical production, and heavy industry, and it is nearly completely generated using fossil fuels. In total, hydrogen production and use accounted for approximately 900 million metric tons of carbon dioxide emissions in 2022.

There are technologies available to clean up hydrogen production. But global hydrogen demand reached 95 million metric tons in 2022, and only about 0.7% of that was met with low-emissions hydrogen. (For more on various hydrogen sources and why the details matter, check out this newsletter from last year.)

Remodeling the worldwide hydrogen economic system won’t be quick or cheap, however it is going down. Annual production of low-emissions hydrogen is heading within the correct path to hit 38 million metric heaps by 2030, in accordance to the World Vitality Agency. The pipeline of most unusual projects is rising snappy, however so is hydrogen quiz, which would per chance presumably well also hit 150 million metric heaps by the stop of the decade.

Veritably each time I portray on hydrogen, whether in transportation or energy or industry, experts notify me it’s necessary to be honest about where that low-emissions hydrogen goes. There are, of direction, disagreements about what precisely the explain of priorities ought to tranquil be, however I’ve viewed just a few patterns.

First, the focus should ideally be on cleaning up the production of hydrogen we’re already using for applications like fertilizer. “The key is replacing current uses,” as Geert de Cock, energy and transport manager at the European Federation for Transport and Environment, put it when I spoke with him earlier this year for an article about hydrogen vehicles.

Beyond that, hydrogen is likely to be most useful in industries where there are no other viable alternatives currently available.

This is a central idea behind an infographic I frequently reference: the Hydrogen Ladder, developed and regularly updated by Michael Liebreich, founder of BloombergNEF. In this graphic, he ranks nearly every hydrogen application, from “essential” uses at the top to “non-competitive” ones at the bottom. His criteria include cost, practicality, and economic viability.

At the top of this ladder are present uses and industries where there’s no change to hydrogen. There, Liebrich agrees with most experts I’ve spoken with about hydrogen.

On the following few rungs are sectors where there’s still no dominant technical solution for cleaning up emissions, such as shipping, aviation, and steel production. You can also view these as famously “hard to abate” sectors.

Heavy industry often requires high temperatures, which have traditionally been costly to achieve with electricity. Cost and technical challenges have pushed firms to explore the use of hydrogen in processes such as steelmaking. For shipping and aviation, there are strict limits on the mass and size of the fueling system, and batteries cannot yet provide the necessary range, leaving hydrogen a plausible option.

In direction of the bottom of Liebreich’s ladder are applications where we already have clear decarbonization alternatives available as of late, making hydrogen a long shot. Rob domestic heating, as an instance. Warmth pumps are breaking through in a huge manner (we effect them on our listing of 10 Step forward Applied sciences this three hundred and sixty five days), so hydrogen has some stiff competition there.

Autos also work well at the bottom of the ladder, alongside two- and three-wheeled vehicles, since battery-powered transit is becoming increasingly common and charging infrastructure is expanding. That leaves little room for hydrogen vehicles to make an impact, at least in the near future.

I’m not ruling out hydrogen as a fuel for any single use, and there’s plenty of room to disagree on specific applications and their respective roles. But given that we now have a growing number of alternatives in our arsenal to combat climate change, I’m betting that, as a general rule, hydrogen will find its niches rather than emerge as the magic multi-tool that saves us all.
