The invasion of Ukraine has proven that reliance on Russian pure fuel is an unstable technique for Europe. Hydrogen energy is one instrument that would assist.

In late February, Russia announced that it will ship troops into two areas of japanese Ukraine — a precursor to its full-scale invasion days later. Hours after Russia’s announcement, German Chancellor Olaf Scholz responded by declaring that his nation was halting Nord Stream 2, a brand new pipeline that will have transported billions of cubic meters of pure fuel from Russia into European markets every year.

Halting such a serious fuel pipeline was not a simple choice for Germany to make. Pure fuel is Europe’s second biggest source of energy, topped solely by oil and petroleum merchandise. Moreover, only 10% of the pure fuel consumed within the EU is produced within the EU; the remainder is imported. Russia is by far the most important supply of these fuel imports at 41% of the quantity.

However European sanctions on Russia have compelled the continent to look for alternatives to Russian pure fuel.  Likewise, many European nations are hoping to decrease their reliance on pure fuel altogether, because of the fuel’ carbon footprint. Whereas pure fuel has a lower rate of greenhouse fuel emissions than different fossil fuels like coal and oil, it’s not almost as clear as renewable energy sources.

As Europe transitions away from pure fuel, hydrogen is one energy supply that would assist. “I feel hydrogen is unquestionably considered as being the longer term alternative for pure fuel,” says Kobad Bhavnagri, the pinnacle of technique for the energy analysis institute BloombergNEF.

In case you’re in the USA, you’re most likely not that aware of hydrogen energy. In America, discussions about renewable energy are inclined to focus on wind and {solar}. Hydrogen has obtained a lot much less consideration from U.S. coverage makers. Bhavnagri attributes this, partly, to America’s giant fuel reserves; the U.S. hasn’t but felt the urgency to depart pure fuel behind. The identical is just not true in Europe, the place hydrogen has seen widespread curiosity from national governments and the EU at large.

In the present day, hydrogen makes up less than 2% of Europe’s general energy consumption. The EU hopes to quickly broaden that determine with a purpose to assist obtain its emissions targets. On the similar time, hydrogen might function a vital ingredient in Europe’s path away from overseas fuel reliance. “The shift to scrub energy is of geopolitical significance for Europe as a result of it helps them cut back their dependence on imports — significantly Russian imports,” Bhavnagri says.

Earlier than contemplating whether or not hydrogen might unseat pure fuel, it’s vital to know what hydrogen is and the quite a few methods it may be produced. Very like pure fuel, hydrogen is a fuel that releases energy when it’s ignited. However, not like pure fuel, pure hydrogen must be produced by people, moderately than merely drilled from the Earth.

Hydrogen could be produced in quite a lot of methods. The three principal strategies have color-coded labels, and so they differ vastly of their carbon footprints.

The primary is grey hydrogen: hydrogen produced from coal or, extra generally, the methane in pure fuel. A particular reaction between methane (CH4) and scorching steam (H2O) produces pure hydrogen (H2) — but additionally makes carbon dioxide (CO2) as a byproduct. Round 98% of hydrogen is grey proper now, which makes hydrogen a serious supply of world CO2 emissions. Most proposals search to section out grey hydrogen as quickly as attainable.

Subsequent is blue hydrogen. Blue hydrogen is produced from the identical course of as grey hydrogen, however provides one additional step: the seize and storage of extra carbon dioxide. That makes blue cleaner than grey, however it definitely isn’t good. Carbon seize know-how requires additional energy to run, and it’s almost unattainable to seize 100% of the CO2.

Blue hydrogen has gained a great deal of curiosity from the United Kingdom, Norway, and the Netherlands, says Martin Lambert, a senior analysis fellow on the Oxford Institute for Energy Research. “However, in some international locations like Germany, the concept of carbon seize and storage remains to be pretty unpopular,” Lambert notes. Plus, blue hydrogen received’t assist lower Europe’s reliance on overseas fuel, since pure fuel is the supply of most blue hydrogen.

That brings us to green hydrogen — the poster baby of the hydrogen motion. Bhavnagri explains that green hydrogen is produced by electrolyzers — massive machines that basically separate tanks of water into pure oxygen and pure hydrogen by working an electrical present by way of them. For actually green hydrogen, the electrolyzers themselves are powered by renewable energy sources like solar panels or wind turbines, such that the complete course of has net-zero carbon emissions.

Most European hydrogen proposals have targeted particularly on green hydrogen, primarily by allocating funding for the development of electrolyzers. That features the EU’s landmark “hydrogen strategy” handed in 2020, which seeks to assemble six gigawatts of electrolyzer capability throughout the EU by 2024, and 40 gigawatts by 2030. It’s trying unlikely that the EU will be capable to hit these targets; a 2021 analysis says that Europe is just on observe to hit 2.7 gigawatts of electrolyzer capability by 2025.

However can increasing the manufacturing of green hydrogen instantly assist Europe shake off its habit to pure fuel? There are definitely causes to consider that it might.

First, since each hydrogen and pure fuel are gaseous types of energy, a number of proposals have thought of repurposing present pure fuel transport pipelines to accommodate hydrogen. Since hydrogen and pure fuel aren’t chemically an identical, which may take some engineering, Bhavnagri says, however it might work. “At minimal, you’ll possible want to exchange some bits of infrastructure like pumps and meters and valves,” he says.

Relatedly, Lambert notes that hydrogen fuel has been discovered to make steel pipelines more brittle and susceptible to cracking, however plastic pipelines are inclined to work positive.

Somewhat than changing pure fuel with hydrogen, some consultants have advocated mixing hydrogen and pure fuel collectively. Lambert says that mixing trials have been significantly profitable in the UK. Now, Britain’s fuel grid is reportedly ready to accommodate a 20% combination of hydrogen as early as 2023.

However “there’s not a lot of a degree” to a fuel combination that’s 20% hydrogen, says Will McDowall, an affiliate professor at College Faculty London’s Institute for Sustainable Assets. McDowall factors out that mixing green hydrogen into the pure fuel grid at a charge of 20% wouldn’t cut back carbon emissions by 20%, however solely by about 7%. That’s as a result of hydrogen is much less dense than pure fuel, so extra of the combination will have to be consumed to satisfy the identical energy demand.

Moreover, Bhavnagri says that electrical energy is mostly a more sensible choice than hydrogen. “In virtually all circumstances, electrical energy, if you should utilize it, is the very best answer,” he says. “It’s the most cost effective and essentially the most environment friendly.”

Bhavnagri factors to the instance of residence heating. Somewhat than switching natural-gas-heated houses over to hydrogen, Bhavnagri means that transitioning to electric heating is the cheapest, cleanest option — so long as that electrical energy is coming from green sources like {solar} or wind.

On the buyer finish, although, hydrogen does have one profit over electrical energy: residents wouldn’t want to modify out their gas-powered home equipment for electric ones, says McDowall. Plus, Bhavnagri notes that hydrogen is way simpler to store than electrical energy; batteries are costly, whereas hydrogen canisters are usually not.

However, finally, hydrogen’s true energy shines on the subject of industries that may’t simply be electrified. The prime instance, most agree, is steelmaking. Proper now, metal manufacturing is essentially powered by coal, and causes a whopping 9% of world CO2 emissions.

The high-heat methods of the steelmaking course of can’t simply be electrified, however they are often converted to hydrogen. Consequently, many metal firms have began eyeing a transition to hydrogen, Bhavnagri says. In actual fact, so-called “green metal” produced by hydrogen is already being sold in Sweden. If hydrogen’s greatest influence is on the metal business, then it could end up that hydrogen is a extra appropriate alternative for coal than pure fuel.

In the present day, European manufacturing of hydrogen lags well behind the EU’s targets. There are a number of causes for that, Lambert says, however an important is that green hydrogen (with its big-budget electrolyzers) stays pretty costly. 

But green hydrogen’s value has been steadily declining, Bhavnagri notes. As renewable energy sources like {solar} and wind have gotten cheaper, so has renewably-produced hydrogen. In the meantime, Russia’s struggle on Ukraine has despatched the worth of pure fuel skyrocketing.

As a consequence of developments like these, Bhavnagri feels optimistic about hydrogen’s prospects. “In case you’d requested me two years in the past, I didn’t have that optimism,” he says. “However, world wide, policymakers are getting behind hydrogen, introducing methods, and placing severe cash to work.”

Nonetheless, there’s yet another potential setback: European hydrogen manufacturing is projected to be too small to fulfill the continent’s hydrogen calls for, by round 50%. So, even when pure fuel have been phased out for hydrogen, Europe may nonetheless discover itself reliant on overseas energy.

That stated, Europe has quite a lot of choices for the place to import its hydrogen — choices that “skew in direction of Africa moderately than in direction of Russia,” Bhavnagri says. North Africa, he notes, might turn out to be a serious supply of low-cost hydrogen because of the area’s sunny local weather driving down the price of solar-powered electrolysis. But critics argue that Europe’s plan to import North African hydrogen is prone to be energy-inefficient, and that African energy ought to be directed in direction of native wants. For now, satisfying hydrogen demand stays an open query for Europe.

However, ultimately, Russia’s invasion of Ukraine has proven that Europe can be much more steady if it decreased its reliance on pure fuel. The planet can be higher off, too. Hydrogen is simply one of many many green alternate options that would assist.
