Capturing carbon using water instead of toxic chemicals

CSS won almost £4 million from the Department for Energy Security and Net Zero to test a method of capturing carbon from its clean fuel process using water.

The funding is helping CSS build a full-scale rig to show that water can be used to separate and store carbon dioxide during the process. This has previously been achieved with amines, a potentially harmful compound derived from ammonia.

Removing the carbon dioxide reduces the carbon footprint of the hydrogen produced and makes the process more efficient.

During the project, the MicroHub test rig will run continuously for 1,000 hours, reliability testing the technology and getting it ready for commercialisation.

Every day, a single module will produce 720kg of hydrogen – enough to fuel a fleet of HGVs – and capture around 1,600kg of carbon dioxide.
