Our Clean Hydrogen Technology

Generating green hydrogen at source is costly, requires subsidies or is subject to penalties. Existing carriers such as ammonia, LOHC and liquid H₂ are expensive and difficult to transport.

Not only has Surrey H2 developed a hybrid water-splitting technology for producing emission-free hydrogen, we can also transport it as a metal carrier. This means we can produce it with some of the worlds cheapest renewable electricity and then use established shipping routes to transport it to where it’s needed.

How it works

H2 process flow (2)

Our patented hybrid process is based on thermochemical metal/ metal oxide water splitting technologies, by implementing an electrochemical step to vastly improve efficiency and reduce the very high temperature requirements.

The looping system circulates a metal/ metal oxide which is regenerated using already well researched and optimised metallurgical techniques. The combined system achieves remarkably high operating efficiencies, to produce ultra-low cost green hydrogen gas at high pressure, ready for storage or usage

Our metal carrier design enables us to combine access to the world’s cheapest renewable electricity with ease of shipping to provide industrial users, nations and governments with a much more affordable and sustainable supply of Green Hydrogen.

  • No critical raw materials — no PGM, no PFAS
  • Water consumed at the demand site, not the arid zone
  • Zinc is recyclable and stores energy indefinitely

Why choose Surrey H2?

Cheaper Production

Our technolgy can generate green hydrogen more cost effectively than existing technologies and accesses the worlds cheapest renewable energy.

Cheaper to transport

Our metal carrier means we can connect the most cost-efficient production sites with users and countries looking for more cost effective green energy.

Self Recycling

Whilst green hydrogen is generated independently, the steam can be recycled to power the system and Zinc Oxide produced at the point of use can be returned to be re-processed.
