The future of global energy might very well have found its champion in Africa with the rise of green hydrogen. Often relegated to the background in discussions dominated by solar and wind power, green hydrogen is emerging as an essential player in ensuring a sustainable global future.
The global hydrogen market already stands at an impressive $130 billion, with the World Bank predicting annual growth exceeding 9%. And while most growth in this domain may remain niche till 2030, the swelling demand for renewable energy sources indicates that green hydrogen’s prominence could soar post that. This surge will be particularly notable in regions blessed with abundant renewable resources and low-cost markets. Africa, with its vast untapped potential, naturally emerges as a focal point of this energy transition.
The principle behind green hydrogen is as revolutionary as it is simple. Using renewable energy, water is split into hydrogen and oxygen. The outcome is a clean fuel, which when consumed, releases only water. This environmentally friendly fuel finds its applications in a range of areas from fueling vehicles to providing warmth to homes.
Diving deeper into the core concept of green hydrogen, its essentially hydrogen produced without harming the environment. The process is called electrolysis, wherein water is split into hydrogen and oxygen using electricity. However, for this hydrogen to qualify as ‘green’, the electricity harnessed must be from renewable sources like wind or solar. This differs starkly from the ‘grey’ or ‘blue’ hydrogen predominantly produced today, which is derived from fossil fuels, mainly natural gas. This traditional method results in substantial carbon dioxide emissions, further aggravating the greenhouse effect.
Green hydrogen’s ascent to dominance is not without challenges. Currently, the primary hurdle lies in its production cost. It still isn’t as competitive as its ‘grey’ or ‘blue’ counterparts. However, the potential of green hydrogen in energy-intensive sectors, such as steel and chemical manufacturing, is undeniable. Achieving economic viability hinges on technological advancements, robust global development investments, and strong legislative commitments. With these factors aligning, green hydrogen might emerge as a central player in the global market in the near future.
Africa is uniquely poised to be at the vanguard of this green hydrogen revolution. The continent is graced with an abundance of sunlight and wind, making it a hotbed for green hydrogen production. Across Africa, initiatives are sprouting, signaling a profound shift towards sustainable development. A noteworthy mention is the SA-H2 venture in South Africa, a collaboration between South Africa, the Netherlands, and Denmark. Aimed at pioneering a hydrogen ecosystem in South Africa, this venture is backed by a robust $1-billion fund.
However, South Africa isn’t alone in this ambition. Angola, too, is carving a niche for itself in the green hydrogen sector, with ambitious projects that could redefine its economy. Two German companies, Gauff and Conjuncta are currently working with Sonangol, Angola’s state-owned energy company for green hydrogen production using some of the Lauca plant’s hydroelectricity. The project is expected to be ready to export from 2024 with 280,000 tons to be generated initially and will position Angola as Germany’s first supplier of green hydrogen.
This German-Angolan partnership is set to put Angola on the map as a reliable trading partner, with Angola also hoping to branch out in the field of wind energy production. This is part of Angolan President João Lourenço’s future-looking plans for sustainable development, with the country wanting to produce 80% of its electricity from renewable sources by 2025.
Integral to the success of such projects is the concept of blended finance. This involves the strategic melding of public or philanthropic funds to catalyze private sector investments in sustainable development. By uniting various sources of capital, projects can achieve a reduced average cost of capital, making them more economically viable.
Moreover, these projects have the potential for creating significant employment opportunities, fostering sustainable development, and driving economic growth. McKinsey’s analysis for the Africa Green Hydrogen Alliance (AGHA) projected a potential GDP increase for member countries of up to $126 billion by 2050, creating over 4 million jobs from green hydrogen investments alone.
This new energy landscape holds promises beyond just economic benefits. It offers a sustainable pathway, merging economic development and climate action. As the world grapples with the climate crisis, green hydrogen offers a beacon of hope. In Africa, where the climate change threat looms large, investing in green hydrogen can be a twofold solution: aiding in global emission reductions while bolstering resilience against domestic climate impacts.
Though Africa contributes a minuscule fraction to global carbon emissions, the continent is proactively striving to minimize its carbon footprint further. With green hydrogen at the forefront, Africa can significantly reduce its carbon emissions while also serving as a key exporter, further aiding global carbon emission reductions.
In the midst of the global energy transition, Africa’s rich renewable resources make it a prime contender in leading green hydrogen production. The continent’s transition from a net fossil fuel importer to potentially a major clean energy exporter signifies not only economic prosperity but also a pivotal role in global energy and climate discussions.
