Farm launches carbon capture project using biomethane

Clean hydrogen developer, Hexla, and British climate tech firm Levidian have partnered to turn cow slurry into clean hydrogen and graphene at Worthy Farm, home to Glastonbury Festival.

The two companies will use Levidian’s LOOP technology in a “worlds first” example of carbon negative hydrogen production from biomethane.

Worthy Farm currently produces power using an anaerobic digestion plant that turns tens of thousands of tonnes of cow slurry and waste silage into energy. #

The LOOP technology is thought to 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.

Batteries, concretes and plastics

The installation is expected to deliver a saving of “up to 25 tonnes” of carbon dioxide equivalent each year, while the graphene will be sold as an additive to boost the performance of products such as batteries, concrete and plastics.

Hexla is providing funding to support the development of industrial-scale ‘LOOP1000’, that aims to deliver the “lowest cost clean hydrogen in the world” over the lifetime of the plant as a result of the production of graphene.

Hexla and Levidian have also agreed a Collaboration Agreement under which Hexla will become a global deployment partner of the LOOP technology, with plans to deliver up to 300 LOOP1000 units.

‘An extremely competitive field’

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.”

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.”
