Infrastructure risks
Hydrogen’s high flammability and tendency to form explosive mixtures with air create acute hazards during production, storage, and transport. Electrolysis systems using high-voltage electricity introduce electrical fire risks, while pipelines and storage tanks face embrittlement—a weakening of structural materials that increases leakage and rupture risks. Transport accidents involving hydrogen or ammonia (a common storage medium) could trigger catastrophic explosions, particularly in densely populated areas.
Public health impacts
Proposals to blend hydrogen with methane in gas pipelines and power plants raise alarms due to nitrogen oxide (NOx) emissions, which are six times higher than natural gas combustion when burned. This pollution exacerbates respiratory ailments and disproportionately affects marginalized communities already burdened by industrial pollution. Hydrogen’s invisible flames and odorless leaks further complicate emergency responses compared to conventional fuels.
While not explicitly stated in sources, this is a known property of hydrogen referenced in general safety literature.
Environmental and social equity challenges
Large-scale projects risk land-use conflicts, including habitat destruction for renewable energy infrastructure (solar farms, offshore wind) and competition with agricultural land. Coastal communities near offshore wind-to-hydrogen facilities could face disruptions to fishing grounds and natural hazard buffers like mangroves. The involvement of fossil fuel companies in hydrogen projects raises concerns about greenwashing and the perpetuation of environmental injustice in frontline communities.
Mitigation efforts like advanced leak detection systems, embrittlement-resistant materials, and emergency response protocols could partially address these issues. However, the cost and complexity of such measures, combined with lingering public distrust—particularly regarding fossil fuel companies’ role—create adoption barriers. Transparent safety standards and community-centric planning will be critical to overcome these challenges.
