South Africa’s green hydrogen ambitions are rapidly moving from concept to construction. In August 2026 the SA-H2 Fund reached a first close of R3 billion to back projects across the value chain, and several Power-to-X projects have progressed into feasibility and engineering stages. That momentum is intensifying debate about land, water and energy allocation, and who will carry the social and environmental costs.
Pressure on scarce resources
Green hydrogen production requires large-scale renewable power and significant water for electrolysis. South Africa faces existing challenges in both areas: an electricity system still in transition and growing water-security concerns flagged by government policy. The National Water Action Plan, published in July 2026, highlights increasingly severe water-supply constraints — a backdrop that makes the allocation of freshwater to new export-oriented industries particularly contentious.
Environmental campaigners and civil society groups have argued that a socially just energy transition must prioritise people and communities over rapid industrial expansion and profit maximisation. Those concerns centre on three linked issues:
- Land use: Large tracts of land are needed for solar and wind generation. In a country shaped by historical land dispossession and entrenched inequalities, dedicating extensive land parcels to export-oriented projects raises questions of rights, benefit-sharing and restitution.
- Water allocation: Electrolysers require reliable water supplies. With agricultural, municipal and ecological demands already under strain, diverting water to industrial-scale hydrogen may heighten competition and exacerbate vulnerability in water-scarce regions.
- Energy and grid impact: Procuring the renewable power needed for hydrogen may have implications for domestic energy security and for the pace and pattern of South Africa’s electricity-sector transformation.
Equity, jobs and industrial strategy
Proponents present green hydrogen as a pathway to decarbonise hard-to-abate sectors, build new industrial capacity and create employment. International finance and policy support have unlocked sizeable capital flows. But civil-society voices stress that benefits must be distributed locally and that projects should not entrench foreign-controlled export industries that bypass local communities.
Earthlife Africa, described in the reporting as cautious and conditional on social and environmental safeguards, emphasises that green hydrogen could contribute to a Just Transition only if projects place communities and ecosystems ahead of rapid development and profit. The organisation argues that questions over who controls the industry and who benefits cannot be separated from questions of land ownership and water rights.

Potential flashpoints and governance needs
As projects advance into feasibility and engineering stages, governance and regulatory choices will determine outcomes. Key risks include:
- Communities being excluded from decision-making on land allocation and receiving limited economic benefit.
- Competition for scarce water resources disadvantaging agriculture, local municipal supply and ecological needs.
- Renewable build-out prioritised for export demand at the expense of addressing national energy deficits or slowing the electricity transition.
Managing these risks will require transparent land- and water-use assessments, clear benefit-sharing mechanisms, and coordination between national departments, provinces and local governments. It will also necessitate strong environmental impact assessments and meaningful community consultation.
The green hydrogen sector may yet deliver industrial opportunity and climate benefits. But the pace of finance and engineering progress is shifting the debate away from abstract potential towards concrete trade-offs. Whether the industry advances as a contributor to a Just Transition depends on policy choices now — about resource allocation, local participation and safeguards to prevent harm.
These developments are still unfolding. Details about individual project locations, water sources and ownership structures remain subject to further announcements and regulatory approvals.
