EU grants not nearly enough to get industry going, say chemical engineers

South Africa is poised to develop into a significant participant within the world power transition, due to its huge renewable power assets (solar and wind) and its plans for inexperienced hydrogen manufacturing.

Inexperienced hydrogen is produced via electrolysisthe place renewable electrical energy splits water into hydrogen and oxygen. Not like grey hydrogen, which is derived from fossil fuels, inexperienced hydrogen emits no greenhouse gases—solely water vapor. It’s seen as a great different to fossil fuels in sectors which can be onerous to impress, reminiscent of heavy business, aviation and long-haul transportation.

We’re chemical engineerswith over 5 many years of mixed expertise within the petrochemical industrywho’ve researched the potential for green hydrogen commercialization in South Africa.

The European Union’s recent pledge of €32 million (R628 million) in grants to help South Africa’s inexperienced hydrogen business reveals that the nation’s potential is being acknowledged. Nonetheless, our analysis reveals that it’s not sufficient. Getting a inexperienced hydrogen business began will want greater than this grant.

Inexperienced hydrogen manufacturing is pricey, costing between US$5 and US$8 (R89-R143) per kilogram—round five times the cost of hydrogen derived from fossil fuels.

It’s also three to 5 occasions costlier than oil. If inexperienced hydrogen is to be cost-effective sufficient to compete with fossil fuels, the inexperienced hydrogen business will want authorities subsidies and incentives for producers. It can additionally want supportive authorities laws, reminiscent of carbon taxes or a requirement to make use of sustainable chemical compounds reminiscent of inexperienced ammonia for fertilizer comprised of inexperienced hydrogen.

Aside from this, substantial worldwide investments will likely be wanted to mitigate the dangers, reminiscent of value overruns, that include constructing large inexperienced hydrogen tasks. In actual fact, South Africa’s future inexperienced hydrogen business is determined by government-backed help from the worldwide north, via mechanisms like sovereign guarantees—a promise by a authorities to cowl the monetary obligations of a mission if it fails to fulfill its debt repayments—or equity stakes—partial possession, sharing in each the earnings and dangers.

European Union grants

The European Union has offered two grants, totaling €32 million (R634 million). The primary is a R490 million grant to assist arrange a regional inexperienced hydrogen hub within the southern Africa area.

The European Union, and South Africa’s ministries of Commerce and Business and Electrical energy and Power, say this grant aims to “leverage R10bn in private and public sector finance across the hydrogen value chain”. In different phrases, this grant is anticipated to entice traders to inject funds into inexperienced hydrogen manufacturing, transportation, storage and downstream industries (together with inexperienced metal and airplane gasoline).

A second EU grant of R138 million is meant to draw further funding to spice up the state utility Transnet’s ports, railways and pipelines. That is in order that inexperienced hydrogen may be exported effectively.

South Africa’s green hydrogen commercialization strategy goals to supply a million tonnes a yr of inexperienced hydrogen by 2030, rising to seven million tonnes a yr by 2050.

If it does this, by 2050 the inexperienced hydrogen business might potentially contribute R75 billion annually—6.5% of South Africa’s gross home product. It might generate R24 billion in tax income, and create as much as 370,000 jobs.

The European Union grants are a step in the direction of this. However they pale compared to the estimated R410 billion (roughly €20 billion) wanted to supply a million tonnes of inexperienced hydrogen by 2030. We calculate that the brand new grants symbolize lower than 0.2% of the funding wanted to get this finished.

There’s a huge monetary hole that should be addressed. South Africa doesn’t have the funds to arrange a inexperienced hydrogen business. Your complete a million tonnes a yr of inexperienced hydrogen that South Africa goals to supply by 2030 is fully depending on world north subsidization.

We consider that the European Union grants will cowl early stage research to evaluate the feasibility of establishing the inexperienced hydrogen business, quite than any capital investments.

Inexperienced hydrogen dangers

Inexperienced hydrogen industries rely upon megaprojects: renewable power infrastructure, electrolysers and water sourcing techniques. Every megaproject sometimes costs over US$1 billion (R19 billion).

The inexperienced hydrogen business can even rely upon a world provide chain in order that the product may be exported. This provide chain will want pipelines and ports in addition to long run agreements with importing international locations.

Megaprojects carry well-known risks—they incessantly exceed their preliminary budgets by 20%-30%, and deadlines are sometimes prolonged by years.

Unanticipated delays, gear failures, or the necessity for extra infrastructure might dramatically enhance prices. This would depart South African mission builders struggling to cowl the cash they’d invested within the tasks. Traders may be left with stranded property if the demand for inexperienced hydrogen didn’t materialize due to competitors from different power applied sciences, regulatory modifications, or slower-than-expected adoption.

The European Courtroom of Auditors recently called for a “reality check” on inexperienced hydrogen, warning of those excessive prices, infrastructure bottlenecks and over-optimistic expectations surrounding the hydrogen market.

If the worldwide north subsidizes or buys shares in these tasks, it might scale back monetary dangers for South African builders. Nonetheless, the probability of value overruns and schedule delays is extraordinarily excessive. These will likely be pioneering megaprojects and so they may very well be worth damaging—the place their returns will likely be beneath the price of capital.

The European Union hopes to import 10 million tonnes every year of inexperienced hydrogen by 2030. We consider the EU ought to bear the dangers and use subsidies to pay for this.

Options

South Africa skilled frequent energy cuts between 2007 and 2024 that hampered financial development. Critics of inexperienced hydrogen argue that renewable power needs to be used domestically earlier than being channeled into producing inexperienced hydrogen for export.

As inexperienced hydrogen researchers, we consider that South Africa can put aside renewable power for native consumption whereas increasing inexperienced hydrogen capability on the similar time.

South Africa can even need to guarantee that native communities profit from the inexperienced hydrogen business.

As world curiosity in inexperienced hydrogen accelerates, the actual take a look at will likely be establishing the appropriate partnerships to drive each financial improvement and the world’s power transition.

South Africa might develop into a worldwide chief in inexperienced hydrogen. The €32 million grant from the European Union could be very welcome as a result of it highlights the significance of worldwide collaboration in addressing the local weather disaster. Nonetheless, there’s a actual hazard that the worldwide south might shoulder a lot of the dangers concerned in growing the inexperienced hydrogen business whereas world north shoppers profit from the product.
