Opinion: Green hydrogen needs a safety-first approach

South Africa’s green hydrogen ambitions are accelerating with major funding commitments and growing international support. Government has positioned green hydrogen as central to its energy transition, backed by initiatives such as the US$1 billion SA-H2 Fund and R370 million from the EU for infrastructure development. But, as investment ramps up, fire and life safety risks must be given equal attention, says Michael van Niekerk, CEO of ASP Fire.

Hydrogen’s unique properties – high flammability, small molecular size and near-invisible flames – make it inherently hazardous. Around 25% of hydrogen fires reportedly result from leaks, highlighting the need for robust detection and prevention systems. These risks are heightened when repurposing existing facilities or operating with limited local expertise.

The unique properties of hydrogen require a comprehensive approach to fire safety, which makes early integration of safety systems, predictive technologies and specialised personnel training critical.

Power reliability also plays a role. Hydrogen infrastructure depends on uninterrupted renewable energy supply and power failures can introduce further safety hazards.

As South Africa builds out its hydrogen economy, embedding safety into every stage – from planning to operations – will be essential.
