As seen in Hydrogen Insight: How an e-fuel buyers’ club is kick-starting the drive for shipping industry to consume more green hydrogen-based fuels 

In January 2026, Hydrogen Insight interviewed ZEMBA’s President and CEO Ingrid Irigoyen about ZEMBA and its e-fuel tender.

Polly Martin of Hydrogen Insight took a closer look at the state of maritime’s clean energy transition and how ZEMBA’s aggregated demand tender process leverages economies of scale.

See one of Irigoyen’s quotes explaining ZEMBA’s theory of change below:

“It’s a way of allowing an entire value chain to hold hands and leap together. Everyone is taking a little bit of risk, everyone is doing a little more than they would do in certain situations, but nobody is entirely exposed to new fuels, new ships, and a new way of doing business,” Irigoyen said.
