Cow slurry to be turned into clean hydrogen and graphene at Worthy Farm

Case Studies

Innovative technology has been installed at Worthy Farm in Somerset, that will see cow slurry turned into clean hydrogen and graphene, in what has been labelled a “world first example of carbon negative hydrogen production from biomethane”.

Home to the Glastonbury Festival, Worthy Farm currently produces power using an AD plant that turns tens of thousands of tonnes of cow slurry and waste silage into clean energy. The LOOP technology (pictured below) will allow the farm to capture the carbon from some of the biomethane produced as part of this process and turn it into super-material graphene and clean hydrogen, which will be used to generate electricity through the existing combined heat and power plant.

The installation is expected to save up to 25 tonnes of CO2 equivalent each year, while the graphene will be sold as an additive to boost the performance of products as wide-ranging as batteries, concrete and plastics.

The project is part of a joint initiative between clean hydrogen developer Hexla and leading British climate tech firm Levidian, featuring the latter’s technology. A collaboration agreement has also been reached via which Hexla will become a global deployment partner of the LOOP system with plans to deliver up to 300 LOOP1000 units, to help drive down the emission of hundreds of thousands of tonnes of CO2e per year. Funding is being provided by Hexla to develop an industrial-scale version, aiming to deliver the lowest cost clean hydrogen in the world over the lifetime of the plant, as a result of the production of high-quality graphene. 

Hexla Founder Andy Yeow said:

“Since early 2019, our team has been researching clean hydrogen production technologies around the world, so it is a great pleasure to be announcing what we expect to be the first of many successful deployments in conjunction with Levidian today. The Levidian LOOP, with its unique solid carbon by-product of high-quality graphene, is the standout technology – from both a thermal efficiency and marginal cost basis – in an extremely competitive field.”

“We are proud to be playing a key role in the scale-up of this truly game-changing technology and are focused on deploying it on an industrial scale to some of the most attractive hydrogen production markets in the world.” 

Levidian CEO John Hartley said:

“The Worthy Farm project is a great example of innovation within the agricultural sector and an important showcase of the vast flexibility and potential of our technology in decarbonising hard-to-abate industries, while unlocking new revenue streams.

“We’re delighted to be working with Hexla to help further our aims for this pioneering technology, including the development of our LOOP1000 unit, which will deliver industrial-scale levels of decarbonisation and place us amongst the best available carbon capture technology on the market.”
