Is green hydrogen a ‘miracle fuel’ or an expensive illusion? Can we decarbonize without it? And what happens when hydrogen hype meets hard economics?

This week on Cleaning Up, Michael Liebreich debates Erik Rakhou, author of Touching Hydrogen Future, in a no-holds-barred discussion moderated by Andrew Critchlow of S&P Global Commodity Insights.

Together, they contest one of the most contentious topics in energy today: hydrogen. Liebreich argues that hydrogen is plagued by physics-driven cost barriers and limited real-world applications, while Rakhou defends its potential as a critical tool for industrial decarbonization, energy resilience, and long-term security.

From the potential of green vs. blue hydrogen, to global ammonia trade routes, Europe’s pipeline ambitions, and China’s hydrogen cost curve, this debate pulls no punches. 

Topics include:

• Whether there’ll ever be a hydrogen-based economy
• Why hydrogen economics remain so challenging
• The role of carbon pricing vs. subsidies
• e-Fuels and hydrogen’s place in transport, steel, and aviation
• Why electrification trumps hydrogen

This episode was recorded at the S&P Global offices in London and originally broadcast as a S&P Global webinar on October 29, 2025. THanks to S&P Global and Andrew Critchlow for hosting the debate.
