‘Let’s get Cracking’ with Dr. Mike Rendall, CTO of AFC Energy

We are delighted to start off Season 9 with Dr. Mike Rendall, the CTO of AFC Energy, an industry veteran with an interesting pivot. The EAH team enjoyed discussing all things hydrogen, ammonia cracking and distributed decarbonisation with a real trove of knowledge and learnings.

About AFC Energy:

AFC Energy plc is a UK hydrogen technology company commercialising both ruggedised fuel cell power generators for the construction market and proprietary ammonia crackers for decentralised and scalable hydrogen production, targeting industrial, transportation, and temporary power markets. The heart of AFC Energy’s value proposition to customers, is its ability to supply hydrogen and / or clean power at customer facilities in modular, scalable quantities—at commercially viable price points and without reliance on government subsidies.

Having built and operated a 400kg/day ammonia cracker to pure hydrogen demonstration plant - the world’s largest - since December 2023, AFC Energy launched the “HY5” in June 2025, a containerized version of its ammonia cracker capable of producing 500kg of 99.99% pure hydrogen per day on a "Fuel as a service" basis. In a joint development partnership with a major global industrial player, it is also developing larger-scale ammonia crackers based on its core technology for applications that include port-side pipeline-filling and hard-to-abate industrial sectors.

Recent strategic partnerships include 50/50 joint ventures with Speedy Hire, the UK’s largest equipment rental company for fuel cell generators, and with Industrial Chemicals Ltd for the scaled production and distribution of low-cost hydrogen across the UK, utilizing ammonia sourced by ICL and AFC Energy’s ammonia cracking technology.

In July 2025, AFC Energy completed an oversubscribed £27.5 million equity raise from institutional and retail investors on the AIM market of the London Stock Exchange.
