Hydrogen demand in the proposed valley is expected to reach up to 185 kt/y by 2030, or 40 –80% of demand in the national hydrogen roadmap. The valley is expected to serve as an industrial cluster, bringing various hydrogen applications in the country together, to form an integrated hydrogen ecosystem. Construction projects include supplying power for a building and the Limpopo Science and Technology Park from fuel cell stationary power. Mobility projects include deploying hydrogen fuel cell buses, mining trucks, forklifts, and hydrogen trucks, and retrofitting current port logistic diesel machinery to hydrogen diesel dual combustion. Green ammonia production by the company will be between 15 t/d (currently) and 45 t/d (in 2030), employing green hydrogen in place of grey hydrogen from steam methane reforming. Ethylene production would use hydrogen for heat and could require 8.5 –12.5 kt/y of hydrogen by 2030. According to the report, chemicals and energy company Sasol is committed to developing ethylene and ammonia using green hydrogen.
In industry, two Sasol projects in Johannesburg were chosen to be the focuses of valley development efforts. The feasibility study identified nine promising hydrogen-related projects in the hub areas, across the construction, industrial, and mobility sectors, that should be the near-term focus of valley developers. These locations will host pilot projects and contribute to the launch of a hydrogen economy in a hydrogen valley. Johannesburg, Durban/Richards Bay, and Mogalakwena/Limpopo were identified as locations with the potential for high future hydrogen demand, to produce hydrogen (eg access to sun/wind and water infrastructure), and to contribute to a just transition. Hydrogen is a key priority for South Africa, and President Cyril Ramaphosa has said that hydrogen fuel cells are a priority as an alternative energy source. A FEASIBILITY study published by the South African Government and partners has identified nine projects across three hubs which could help kickstart establishment of a hydrogen valley.
