This week, the Angolan state vitality firm Sonangol and two German corporations, Gauff Engineering and Conjuncta, signed a memorandum of understanding to assemble a manufacturing unit.
The proposed plant is predicted to provide round 280,000 tons of inexperienced ammonia for export beginning in 2024.
Inexperienced hydrogen proponents view it because the silver bullet to make Germany’s financial system climate-friendly.
The Ukraine battle has made the necessity much more pressing.
In accordance with comparability portal Verivox, electrical energy costs in Europe’s greatest financial system rose by virtually 20% within the second quarter of 2022. Fuel has turn out to be virtually twice as costly.
Thus, the Angola undertaking is essential from the 2 German corporations’ views.
“It should assist Germany swap extra rapidly to inexperienced vitality and turn out to be impartial of gasoline and Russia,” stated Conjuncta CEO Stefan Liebing.
Inexperienced hydrogen as an vitality supply is taken into account climately pleasant
Inexperienced hydrogen in its place
In accordance with Sonangol, Angola has appreciable potential to provide inexperienced hydrogen.
This different vitality supply, produced by splitting water into hydrogen and oxygen utilizing renewable electrical energy, reduces emissions, and local weather activists think about it a significant arsenal in combating local weather change.
In accordance with estimates, Angola has untapped water reserves. The Southern African nation makes use of solely 5% of its 47 main water catchment areas.
Diamantino Pedro Azevedo, Angola’s minister of mineral sources and petroleum, advised DW that the Angolan authorities had set a purpose of accelerating renewable vitality sources to 70% by 2025.
“This exhibits that Angola has nice potential for the event of hydrogen initiatives and likewise has infrastructure that may enable us to develop the undertaking with some pace and high quality,” he stated.
Africa’s vitality wealth: wind, water, and solar
Many African nations might produce climate-friendly hydrogen.
“The African continent is sort of endowed with all types of vitality sources; wind, hydropower,” Nigerian vitality skilled Chigozie Nweke-Eze advised DW.
“It has a number of alternatives to generate renewable vitality sources, which could possibly be used inside the continent and will also be exported for some revenues that could possibly be used inside the continent.”
However these renewable vitality sources are hardly used: In 2018, the continent generated about 180 Terawatt-hours (TWh) of electrical energy from renewable sources — lower than 0.02% of the estimated potential.
Consequently, there’s rising curiosity in inexperienced hydrogen from Africa — and never simply from Angola.
Final 12 months, the German Federal Ministry of Analysis introduced a research of the place inexperienced hydrogen could possibly be produced in Western and Southern Africa.
Germany might use ships to move inexperienced hydrogen from Angola
Investing in Africa’s inexperienced vitality
The German authorities has pledged €40 million ($41.9 million) for a nationwide technique to develop inexperienced hydrogen in Namibia. Along with Angola, Germany has additionally arrange a hydrogen workplace in Nigeria.
However such initiatives include dangers, says vitality skilled Nweke-Eze.
“It will be important that we adhere to sustainability standards within the manufacturing of inexperienced hydrogen,” he stated.
In accordance with the vitality skilled, pursuing renewable vitality should not sacrifice financial development, industrialization, and growth in these nations for the vitality transition.
He stated that it’s important that new jobs created by the undertaking stay in Angola and that information and experience within the inexperienced hydrogen subject are shared.
The dearth of vitality safety can be a threat issue, he famous.
In accordance with the Worldwide Power Company (IEA), no less than 77% of Africans usually are not related to the ability grid.
“So you continue to are battling with points concerning vitality safety. So that you need to remedy that first,” Nweke-Eze stated.
“Inexperienced hydrogen then turns into actually possible in areas the place they’re complementary to already present efforts for vitality growth and vitality safety.”
The water issue
Furthermore, inexperienced hydrogen manufacturing consumes a number of water. On the similar time, some areas of Africa endure from dire water shortages.
Solely 24% of the inhabitants in Sub-Saharan Africa has entry to protected ingesting water, the United Nations estimates.
“We have to guarantee that water sources for inexperienced hydrogen manufacturing don’t compete in any means with different makes use of of contemporary water,” Nweke-Eze cautions.
In Angola, that is not an issue, Stefan Tavares Bollow, Gauff’s Director-Basic, stated.
“Angola has sufficient clear water. You need not desalinate seawater to get the water you want.”
Desalinated seawater, nevertheless, may be used. With sufficient water, vitality producers might generate about 120,000 TWh of inexperienced hydrogen annually in West Africa alone.
Germany will want about 745 TWh in 2030, in keeping with the German Renewable Power Federation.
The manufacturing of inexperienced hydrogen requires large quantities of water
Logistical challenges
However there’s one other downside: Transportation. To date, sea transport has been thought-about essentially the most cost-effective: Pipelines could possibly be less expensive for shorter distances.
However at the moment, there are primarily pipelines transporting pure gasoline from North Africa to Europe or the Center East.
The West African Fuel Pipeline (WAGP) community — which transports gasoline from Nigeria to neighboring Benin, Togo, and Ghana — does supply the potential for hydrogen transport.
And the not too long ago launched Nigeria-Morocco pipeline undertaking might doubtlessly be prolonged to Europe.
So earlier than massive portions of hydrogen might be exported from Africa to Europe, quite a bit nonetheless must occur.
However Nweke-Eze stated he’s cautiously optimistic.
“Germany has been enjoying a job in sub-Saharan African nations. However we hope that this may enhance sooner or later in a extra balanced partnership,” he stated, including that when that occurs, nothing will stand in the best way of the move of inexperienced vitality from Africa to Europe.
