Brazil's renewable resources, sound economy and supportive policies could make it a powerful advocate for green H2, writes Pamela Machado
The Cop 30 UN climate summit kicks off in a few days in Brazil against a backdrop of slowing global energy transition momentum and outright hostility from US president Donald Trump's administration to policies aimed at tackling climate change.
Hydrogen has not been immune to these trends. Recent Cop summits have given the industry a platform to showcase its decarbonisation potential, but hydrogen is expected to receive a more modest hearing when delegates gather in Belem, reflecting the more downbeat global mood and the industry's slow development. This year has seen nothing like the level of final investment decisions (FIDs) for hydrogen projects that was anticipated at the start of 2025, as a combination of familiar issues — policy uncertainty, infrastructure bottlenecks and difficulties securing offtake agreements — have hindered progress for many schemes.
The hydrogen sector is going through an "era of maturation and is moving from ambition to delivery — a transition similar to what solar, wind and battery industries have gone through as well", says Ivana Jemelkova, chief executive with lobby group the Hydrogen Council. This phase is "inevitably paired with attrition", Jemelkova tells Argus, with only projects demonstrating "the strongest business cases" able to line up enough financing and support to move forward.
But Cop still offers an opportunity, she says — the "perfect place to advance practical solutions" to address challenges with mechanisms such as contracts-for-difference (CfD), national mandates and to set up "alliances to aggregate demand in sectors like fertilisers". Countries with renewable power potential — particularly emerging economies — have also used recent Cop summits to unveil clean hydrogen production ambitions, but momentum has slowed this year in regions such as Latin America and sub-Saharan Africa as companies have scaled back production goals and import ambitions.
Emerging talent
This is another area where Cop offers a chance for revival, Jemelkova argues. "As of 2025, 65 ... countries have a hydrogen strategy, of which 29 are emerging economies," she says. "This year's update of nationally determined contributions provides an opportunity to set detailed hydrogen targets." So far, there have been few signs that hydrogen will play a greater role in countries' plans, however, and the focus might lie elsewhere, given the sector's slower-than-expected progress.
Brazil has used its presidency to promote hydrogen for clean industrialisation. It has announced several funding schemes, partnering with international bodies, including UN industrial development organisation Unido and the Green Climate Fund over the last year. But these initiatives have yet to yield any FIDs.
International non-profit industry decarbonisation programme Industrial Transition Accelerator (ITA) chose Brazil as its first focus country because it combined government ambition, economic fundamentals and a promising project pipeline. ITA is working with 15 projects in Brazil and had hoped that some of these would reach FID ahead of the summit, but none is now expected this year.
While projects reaching FID "would be a powerful symbolic accomplishment, if they cannot quite do so in time for the event, it is not a fundamental cause for concern", ITA says, as the programme's goal "is not just about individual FIDs", but also about overcoming systemic obstacles, such as high financing costs.
Brazil's broader agenda as Cop president has included a pledge for nations to increase production and adoption of sustainable fuels, which seems likely to emphasise biofuels more than hydrogen-based alternatives. But planned Cop talks on increasing renewable power generation and integrating carbon markets into a global system should promote the uptake of hydrogen and derivatives, even if indirectly.
