How Africa could become a global hydrogen powerhouse

Africa could supply the whole world with affordable low-carbon energy in the form of hydrogen, a new report suggests.

How Africa could become a global hydrogen powerhouse

In its Africa Energy Outlook 2022, the International Energy Agency (IEA) says Africa’s rich renewable resources particularly solar energy, but also onshore wind – are the key to unlocking this potential. Africa could produce 5,000 megatonnes of hydrogen a year at less than $2 per kilogramme equivalent to “global total energy supply today,” Hydrogen is an abundant and energy-rich gas that occurs naturally in water and fossil fuels like natural gas, coal, and petroleum, explains the US Energy Information Administration. Hydrogen can be used as a fuel by separating it from these sources.

When renewable energy such as sun or wind is used to power the separation of hydrogen from oxygen in water molecules, the hydrogen produced is classified as carbon-free ‘green hydrogen When hydrogen is used as a fuel, the only waste element it produces is water. This makes it better for the planet than burning fossil fuels, which contribute to global warming by producing carbon dioxide, and to air pollution. frica has one of the world’s biggest potentials for producing hydrogen from low-cost renewable electricity, the IEA says. Africa has 60% of the world’s best solar resources, but only 1% of current solar generation capacity.

Wind power is also a big resource. Arid and semi‐arid areas are ideal for wind and solar, the IEA says, especially in North Africa, the Horn of Africa and Southern Africa. By 2030, Africa could produce 80% of the new power generation it needs from solar, wind, hydropower, geothermal and other renewable energies, the IEA says. The falling cost of both solar units and hydrogen production is predicted to further increase Africa’s hydrogen potential. In the IEA’s model, this results in Africa’s $2-per-kilogramme hydrogen being up to half the price of hydrogen from the rest of the world. About 600 million people – 43% of Africa’s population – currently don’t have access to electricity. Most of these people live in sub-Saharan Africa. Countries including Ghana, Kenya and Rwanda will be on track for full access by 2030, the IEA predicts in its Sustainable Africa Scenario. This is mostly achieved by extending national grids, it says. In rural areas where most people without access to electricity live – solar mini-grids and standalone systems are the most viable solutions. To reach universal access to affordable electricity by 2030, Africa will need to connect 90 million people a year, the IEA says. This is three times the rate of recent years.
