The future is clear


What we do

Our goal is to produce affordable, carbon-negative hydrogen. We convert biogenic material into Clear Hydrogen, simultaneously removing carbon from the atmosphere.

Our technology is radically different, taking a completely new approach to hydrogen production. This means it is more adaptable, scalable and efficient than alternatives.

The Solution

Our RiPR technology is a game-changer, as it is free from many of the downsides experienced by alternative hydrogen production methods. By taking a radical and innovative approach, we believe we have solved many of the biggest challenges facing the hydrogen production industry today.

The Difference

RiPR does not need exotic raw materials, green electricity or large amounts of water. We believe we have eliminated many of the challenges faced by other technologies. Our RiPR technology produces little to no harmful tars and is adaptable to a wide range of biogenic feedstocks.

The Opportunity

The global hydrogen market is £100 billion and the vast majority of this demand is currently met using grey hydrogen production. Not only is Clear Hydrogen able to compete based on price, but it is part of the solution, not the problem, reducing emissions.


Our story

Mark, James and John met at their local coffee stop. They founded Wild Hydrogen based on an idea that Mark had been musing on for many years.

Now, the company is well on its way to building a commercial plant, proving that there is a viable and sustainable method for creating negative-emission fuel.
