German Tech Giant Places Major Bet On Green Hydrogen

Green Hydrogen

Hydrogen is turning into the next media star after solar and wind. In its latest claim to fame, two spinoffs of German tech conglomerate Siemens are joining forces to advance green hydrogen technology by building wind-to-hydrogen systems to help decarbonize the global economy. Green hydrogen is touted as a solution to many climate change problems: the element can be an energy carrier, it can be used to store energy and it can be used in fuel cells to power vehicles. Green hydrogen is a particularly attractive option because its production comes from hydrolyzing water using electricity produced by renewable systems, meaning it has a much lower carbon footprint than gas- or coal-sourced hydrogen.

Siemens Gamesa and Siemens Energy have therefore joined a growing group of green hydrogen proponents, many of whom see it as the ultimate solution to the planet’s pollution problem.

The two plan to invest $120 million over five years to develop a fully integrated offshore wind-to-hydrogen system that involves a turbine with an electrolysis system integrated into it, the companies said in a press release this week. They are aiming for a full-scale demonstration of their pilot by 2025 or 2026.

“Our wind turbines play a huge role in the decarbonization of the global energy system, and the potential of wind to hydrogen means that we can do this for hard-to-abate industries too. It makes me very proud that our people are a part of shaping a greener future,” the chief executive of Siemens Gamesa, Andreas Nauen, said in the release.

“With these developments, the potential of regions with abundant offshore wind will become accessible for the hydrogen economy. It is a prime example of enabling us to store and transport wind energy, thus reducing the carbon footprint of economy,” said the head of Siemens Energy, Christian Bruch.

But for all its promise, green hydrogen production is not a trouble-free technology. It is a very expensive technology that has made some experts warn it is unlikely to be economically viable for years and maybe decades to come. And yet, some are forecasting major cost drops for the technology.

Wood Mackenzie analysts, for instance, last year wrote in a report that they expected the production costs of green hydrogen to fall by as much as 64 percent by 2040 and in some places, even sooner.

“On average, green hydrogen production costs will equal fossil fuel-based hydrogen by 2040. In some countries, such as Germany, that arrives by 2030. Given the scale up we’ve seen so far, the 2020s is likely to be the decade of hydrogen,” the author of the report, senior research analyst Ben Gallagher wrote, adding, “Rising fossil fuel prices will boost green competitiveness, further strengthening the case for this technology in the coming years.” 

And yet, this cost reduction will require quite a solid effort: right now, green hydrogen production costs between three and six times more than gas-derived hydrogen. On the other hand, the prices of gas-derived hydrogen may rise as demand for gas rises, somewhat leveling the playing field. This, however, suggests that green hydrogen would depend on gas prices for its competitiveness rather than on technological advancements that would make the process itself cheaper.

That the energy transition will come at a cost is clear. The question is, how high this cost will be, and how much of the world will be able to afford it. Solutions such as the one Siemens Gamesa and Siemens Energy are working on sound like the way to make the process cheaper and bring green hydrogen closer to mainstream reality. However, it’s worth bearing in mind these solutions would be region-specific rather than universal. For now, mainstream green hydrogen remains more of a promise than a reality.

    That and also governments around the world will put an end to the fossil fuel cabal stiffing society by not paying damages for externalities. The wild party of not paying for pollution caused harm will come to a halting end. When it sinks-in that we now have less expensive alternatives for energy, when there is limited need to pump oil it will come with increased price to reimburse for losses. Carbon tax if not a true tax it is a liability payment. Liability requires to stop the free ride on the health havoc from the toxic chemicals, the destruction to agriculture and forestry, building exterior, and even car finishes. Above all the global climate holocaust bill can not stay unpaid as a subsidy to fossil fuel profits. Maybe the United Nations should take coordinating action.

    No more oil, gas, and coal damages to society gone unpaid, will mean fossil hydrogen will become three to six times more expensive than clean hydrogen. Will this price adjustment be soon followed with all extraction activities ceasing to exist?

    For how long after the freeloading subsidy is terminated will drilling, pumping, and mining continue? Will it be before or after the end of this decade that our children's lungs will become safe again from putrid air?

    When comparing hydrogen costs vs other energy alternatives, we must include infrastructure costs. Hydrogen must be stored and shipped (pipeline and other methods) using special metallurgies due to the properties of hydrogen. It is extremely corrosive to the steel used in oil and gas pipelines.

    Typically incoherent nonsense from oilprice.com.

    The problem here is that ELECTROLYSIS of water has a lot of problems. Never mind the additional safety concerns that come with H2, the process of electrolysis of saline water poisons the electrodes - very quickly - making the process a chemical engineers nightmare. It turns out - beyond the simple theoretical, back of an envelope, enthalpy and differential SP calculations - to require a horrendously expensive, fragile and unworkable Heath Robinson solution. But that's OilPrice.com for you.

    Anyone that isn't a journalist wonders what the hell the point of this site is beyond the charts. But gives me insight into the workings of journalists and why the world of politics, economics and policy is so poorly understood by the general public.
