Scaling Green Hydrogen: Innovations in Electrolyzers

When Raffi Garabedian co-founded Electric Hydrogen in 2020, he saw existing electrolyzers as too small and expensive to make green hydrogen economically viable. Instead of building standard sub-megawatt units, his team aimed for 100-megawatt systems at half the industry cost.

Initial market enthusiasm brought millions in capacity reservations, fueling construction of a Massachusetts manufacturing plant. Then came the "trough of disillusionment" – a global cooling on hydrogen as projects faltered under high costs.

In this episode, Lara Pierpoint talks to Raffi about taking big technology risks while building a factory during market volatility. He explains why startups, not incumbents, are best positioned to drive the cost reductions needed to make green hydrogen competitive with fossil alternatives.
