>>> In the United States, the Department of Energy is doling out billions of dollars in federal funding to create up to 10 “hydrogen hubs”.

>>> International Renewable Energy Agency: diverting too much green energy toward hydrogen production could be counterproductive.

Contrary to much decarbonization hype, jumping on the green hydrogen bandwagon is not a silver bullet solution to climate change. In fact, it’s a double-edged sword. A versatile energy carrier, hydrogen is projected to play a major part in decarbonization of global manufacturing and industrial supply chains, but its production, transport, and conversion require major inversions of energy and investment that could slow down the rest of the green energy transition if mismanaged.

Hydrogen is touted as a key element in any decarbonization trajectory because unlike solar and wind energy, hydrogen can be used as a combustible fuel source. This means that it can replace fossil fuels in industrial furnaces, but instead of emitting carbon dioxide and other greenhouse gasses when burned, it leaves behind nothing but water vapor. The implications of a wide-scale replacement in high-heat industrial applications are enormous. “Replacing the fossil fuels now used in furnaces that reach 1,500 degrees Celsius (2,732 degrees Fahrenheit) with hydrogen gas could make a big dent in the 20% of global carbon dioxide emissions that now come from industry,” Bloomberg Green wrote last year in report titled “Why Hydrogen Is the Hottest Thing in Green Energy.”

The problem is that hydrogen is only as green as the energy source used to make it. The process of creating hydrogen is energy intensive, and the vast majority of hydrogen being produced today is made using fossil fuels. This is referred to as gray hydrogen, and it is already used widely in global industry. Green hydrogen is made with all renewable energy sources. ‘Blue hydrogen’ is also sometimes used as a third designation referring to hydrogen produced using natural gas, which yields lower emissions than other fossil fuels and is seen by some as a stepping stone to full decarbonization.

While it seems like it would be a no-brainer that the increased production and consumption of green hydrogen would be an obvious win for the energy transition, however, the reality is not so simple. A new report by the International Renewable Energy Agency (IRENA) warns against the “indiscriminate use of hydrogen,” cautioning policy-makers to weigh their priorities carefully and to consider that extensive use of hydrogen “may not be in line with the requirements of a decarbonised world.” The report goes on to single out green hydrogen, arguing that it “requires dedicated renewable energy that could be used for other end uses.” As such, diverting too much green energy toward hydrogen production could actually slow down the decarbonization movement as a whole.

According to current projections, hydrogen use is going to skyrocket between now and 2050 in order to meet the energy and fuel demands of a net-zero emissions future. In G-7 countries alone, hydrogen use could balloon to four to seven times its current size by mid-century.

In the United Kingdom, the government is experimenting with the use of hydrogen to heat homes in the midst of a major energy crisis. By next year the nation will have chosen its very first “hydrogen village” to take part in a two-year pilot program. Not everyone is enthusiastic about the experiment, but it is likely just the beginning of such ventures as European nations move to shore up domestic energy independence while simultaneously trying to reach their stated emissions targets.

In the United States, the Department of Energy is doling out billions of dollars in federal funding to create up to 10 “hydrogen hubs” across the nation. These would function as “a network of clean hydrogen producers, potential clean hydrogen consumers and connective infrastructure located in close proximity.” And the $7 billion dollars earmarked for the hubs is only one part of hydrogen investment at the federal level. The Inflation Reduction Act also provisioned a clean hydrogen production tax credit and created other decarbonization incentives such as carbon capture tax credits that could prove to be a boon to the nascent but fast-growing green hydrogen sector.

On the whole this is good news for the energy transition and for global climate goals. But the growth of the green hydrogen industry will need to be balanced with other energy needs going forward for a smooth trajectory toward decarbonization. (Such a balance is not happening. Moreover, decarbonization needs to mean LESS production of greenhouse gases rather than relying on CO2 removal from the atmosphere, an extremely expensive activity at a scale that would make a difference.

The fossil fuel industry has a new plan for Appalachia: Blue hydrogen.

An alliance between some of the largest corporations in the energy business — Shell, General Electric Gas Power, EQT Corporation, Equinor, Mitsubishi, US Steel and Marathon Petroleum — announced in a press release late last week their plan to create a “hydrogen industrial hub” in Ohio, Pennsylvania, and West Virginia. Their plan is to work with local stakeholders in the process, creating “a national model for sustainable energy and production systems.”

The companies are putting their faith in an element that’s gained traction as an energy form in recent months, as the bipartisan infrastructure bill includes billions of dollars to build out clean hydrogen energy development. Hydrogen is also the most abundant element in the universe, existing in water, alcohols, and the like.

Producing hydrogen as an energy source requires separating H atoms from other elements in the molecules where it naturally occurs (so, removing the H from H2O, for example). This is most commonly done commercially using steam to separate hydrogen from methane in natural gas; the finished product is referred to as ‘blue hydrogen,’ because it is emissions-free when burned, but is made with polluting sources of energy. (Its green counterpart, ‘green hydrogen’ is made by separating hydrogen atoms from water using renewable sources of energy, like wind and solar.)

Matt Kelso, manager of data and technology at the non-profit environmental watchdog FracTracker Alliance sees the investment in hydrogen as “an extension of the existing polluting industries, by the exact same companies that are polluting our air, land, and water today.”

“It is an excuse to keep drilling, obfuscated under a new identity, in an environment where there is increasing awareness of the damages that oil and gas extraction has caused to the region,” said Kelso, who lives in Pittsburgh, near southwest Pennsylvania’s oil and gas hub.

The plan will capitalize on the region’s natural gas stores, largely trapped in the Marcellus Shale geologic formation, untapped during the fracking boom of the early 2010s. The technique, which involves thrusting drilling fluid deep into rock formations, first vertically, then horizontally, to reach gaps in which natural gas is stored and release it. At the time, fracking promised to resuscitate the oil and gas industry, bringing an economic renaissance to the region.

In reality, these plans didn’t pan out: Actual job numbers paled in comparison to those promised. A 2021 economic analysis by the non-profit think tank Ohio River Valley Institute found that jobs in Appalachian fracking counties climbed by merely 1.6 percent in the 2010s, compared to the 450,000 jobs that industry estimates from the early 2010s laid out. It also led to an oversupply of natural gas that the industry is now trying to offload (most notably by pushing plastics).

The companies are positioning the move as an environmentally-sound one, or a way to achieve “aggressive net zero carbon goals,” Bill Newsom, president and CEO of Mitsubishi Power said in a press release. In fact, the fossil fuel industry more broadly has rallied around using carbon capture and sequestration as a technique to eliminate emissions from steam-methane reforming in the hydrogen production process.

These emissions are substantial. An August, 2021 report out of Cornell and Stanford Universities found that the carbon footprint that comes with creating blue hydrogen is 20 percent larger than that of burning natural gas and coal for heat and 60 percent greater than burning diesel oil for the same purpose.

Thus, carbon capture and storage — in which carbon dioxide is collected at the source of emissions and shot underground into stores — is essential to the fossil fuel companies’ plan if it is to be ‘net zero.’ But CCS comes with its own set of risks; pipelines carrying captured carbon have, in the past, exploded, and in the Marcellus Shale, where oil and gas wells, many abandoned, dot the landscape, shooting it underground could prove geologically risky — pressure from two wells interacting could lead to explosions.

Though the nuances of the ‘blue hydrogen hub’ plan remain opaque, and it is not clear how close any of these corporations are to receiving the permits required to see it through, they have a topline goal to generate “thousands of new jobs” and “protect current jobs,” per the release on the hub.

Matt Kelso remains dubious of this claim. “Based on the past actions of the industry, I would be highly skeptical with whatever figure they put forth,” he said, citing a Shell ethane cracker plant in Pennsylvania that was touted as generating 17,000 jobs but actually created 600. “The economic promises were knowingly inflated by several orders of magnitude, which undoubtedly helped secure better state investment offers,” he said of the project.

Even so, much of the landscape of Appalachia has yet to be reclaimed from already-dying industries; abandoned coal mines continue to leach into waterways and abandoned oil wells sit uncapped, leaking planet-warming methane all the while. The quick shift to a new energy form begs the question of whether a region is ready for a new wild west era, as the remnants of old ones have yet to be cleaned up.
