Systemic gaps in green hydrogen electrocatalysts: Rethinking interfacial dynamics for equitable energy transitions

Indigenous communities in lithium-rich regions (e.g., Salar de Atacama) possess millennia-old water management systems that could inform sustainable brine extraction for catalysts, yet their knowledge is excluded from electrocatalyst design. The 'double layer' phenomenon described in the headline mirrors Indigenous concepts of interfacial balance (e.g., Quechua *pachamama* as a living interface), which could reframe electrochemical interfaces as relational rather than mechanistic. Current models treat water as a resource to exploit, not a sacred commons to steward.

The 'efficiency' paradigm echoes colonial-era resource extraction, where technical fixes (e.g., Haber-Bosch nitrogen fixation) displaced local agricultural knowledge without solving hunger. Historical parallels include the 1970s 'hydrogen economy' hype, which collapsed due to oil price volatility and corporate capture—risks repeating with today’s green hydrogen push. The electrocatalyst interface problem reflects a broader pattern of 'technological solutionism' in energy transitions, where complexity is reduced to single-variable optimization.

In China, microbial electrolysis cells inspired by fermented foods (e.g., *jiang*) achieve 80% efficiency without rare metals, challenging the platinum dependency narrative. Pacific Island nations, facing existential threats from sea-level rise, are developing wave-powered electrolysis systems that integrate with traditional voyaging canoes—an example of culturally resonant green tech. The Western focus on 'double layers' in catalysts contrasts with Eastern philosophies like *wu wei*, which prioritize harmony over control in energy systems.

The double layer model, while useful, oversimplifies the role of surface defects and electrolyte impurities in real-world systems, where 90% of catalyst degradation occurs. Emerging operando spectroscopy techniques (e.g., X-ray photon correlation spectroscopy) reveal dynamic restructuring at interfaces, contradicting static models. The omission of microbial electrocatalysis (e.g., *Geobacter* species) in mainstream R&D highlights a bias toward abiotic solutions, despite their lower energy requirements.

Artists like Tomás Saraceno’s *Aerocene* project visualize hydrogen as a medium of interspecies collaboration, contrasting with its industrial framing as a commodity. In Sufi traditions, the 'breath of life' (*ruh*) parallels hydrogen’s role as an energy carrier, suggesting spiritual frameworks for sustainable production. The mechanistic language of 'layers' and 'interfaces' in electrochemistry lacks the poetic resonance of Indigenous metaphors like the 'skin of the earth' for catalyst surfaces.

Scenario modeling by the International Energy Agency (IEA) assumes 24 EJ of hydrogen by 2050, but this ignores the 30% water demand increase in arid regions, risking 1.5°C overshoot. Alternative pathways (e.g., decentralized solar-to-hydrogen in sub-Saharan Africa) could reduce transmission losses by 40% but require rethinking patent regimes. The focus on 'cheaper catalysts' neglects the need for circular supply chains, where spent catalysts are repurposed into building materials—a model already practiced in some Indigenous communities.

Women in Global South energy cooperatives (e.g., Barefoot College’s solar engineers) are excluded from catalyst R&D despite their expertise in off-grid systems. Black and Indigenous chemists face systemic barriers in patenting low-cost catalyst designs, with 92% of hydrogen patents held by firms in the Global North. Grassroots groups like the *Hydrogen Justice Collective* argue that 'green hydrogen' must prioritize energy democracy over corporate profit, yet their input is absent from high-level policy forums.
