Only 7% of Planned Green Hydrogen Projects Were Built on Time, Exposing Hormuz-Dependent Economies
A Nature Energy study tracking 190 projects found green hydrogen delivery failing at scale, deepening exposure for Asian economies most reliant on Strait of Hormuz oil flows.
Fewer than one in fourteen planned green hydrogen projects globally were completed on schedule in 2023, according to a Nature Energy study tracking 190 projects across three years, as reported by oilprice.com on Tuesday (2026-08-18). The figure punctures assumptions — held by governments, developers, and multilateral bodies — that deployment in hard-to-abate sectors like steelmaking, shipping, and heavy transport was following anything resembling a credible delivery path.4
The delivery gap carries direct weight for energy security. The Strait of Hormuz handled 18.2 million barrels per day of crude oil and refined products in 2025, per OGJ, along with roughly one-fifth of global LNG trade. Green hydrogen in those same industrial sectors was supposed to gradually erode the kind of fossil fuel dependence those flows represent. The completion data suggest erosion at meaningful scale is years away at minimum.2,4
Kpler data cited by oilprice.com showed tanker crossings at Hormuz fell to just five on Wednesday (2026-08-12) and nine on Thursday (2026-08-13), against a monthly average of 12. The U.S.-Iran standoff constraining those flows shows no sign of near-term resolution.3
Asian economies carry the greatest exposure. OGJ data show nearly 80% of Hormuz oil flows go to Asian buyers. China imported close to 5 million barrels per day through the strait; India, Japan, and South Korea each imported roughly 2 million b/d. The combined dependence of those four economies alone runs above 11 million barrels per day through a passage where crossings have been running well below historical norms.2
China is constructing a 100-MW green hydrogen project, oilprice.com reported. Against nearly 5 million barrels per day of crude routed through a contested waterway, that capacity is negligible in any supply shock scenario. Scale and delivery speed are both problems the sector has not solved.3,4
Oil markets have been slow to price the full supply-side exposure. During the week of 2026-08-03, traders focused on a U.S. commercial inventory build of over 17.4 million barrels rather than the structural constriction at Hormuz, oilprice.com reported. ICE Brent crude front-month stood at $93.60 per barrel as of 2026-08-22.3
Traders expected early disruptions to last days, not weeks, the Economist reported. That read has proven too optimistic. JPMorgan Chase estimated on March 3rd (2026-03-03) that Iraq and Kuwait had roughly three and 14 days respectively before hitting storage limits that would force shut-ins of nearly 5 million barrels per day of Hormuz exports, roughly 5% of global production.1

The countries most exposed to a protracted Hormuz disruption are the same ones that most needed green hydrogen deployment to accelerate: China, South Korea, Japan, and India all appear in OGJ's data as major strait-dependent crude importers, and all have announced ambitious hydrogen targets that the Nature Energy study suggests have not translated into on-time construction. If the U.S.-Iran stalemate extends into the coming weeks, oilprice.com reported, the physical oil market could reach a tipping point beyond which shortages emerge — and with 93% of planned green hydrogen projects unbuilt on schedule, no clean alternative is positioned to absorb any meaningful share of that shock.2,4,3
