How it Works

RIPR EXPLAINED

Gasification

Our RiPR technology is – at its heart – very simple. It turns biogenic material into hydrogen through supercritical water gasification (SCWG).

Biogenic material is anything generated by living organisms. This includes things like plant matter but also hydrocarbons such as plastics.

Because our technology uses gasification, it does not involve electrolysis. This means it requires far less electricity. It is a tuneable process that allows us to produce different Carbon Dioxide Removal (CDR) products. We believe we have a robust technology that can help solve climate change.

Read through the process below to understand how it works in more detail.

Inputs

Our RiPR technology is compatible with almost any biogenic feedstock, ranging from waste materials to grasses.

Industrial Waste

Domestic Waste

Grown Fuel Crops

Herbal leys

Wood waste

Seaweed

Plastic waste

Agricultural residues

Municipal solid waste

Animal waste

Refuse derived from waste

Feedstock Flexibility

Our RiPR technology is compatible with a wide range of biogenic material. This feedstock adaptability – combined with the need for minimal preparation – gives it significant advantages over alternative methods. For example, it is compatible with wet feedstocks, opening up a whole range of possibilities, as well as decreasing transport and processing costs.

RiPR Technology

Unlike green hydrogen produced through electrolysis, our RiPR reactors have no requirement for large amounts of green electricity and can even operate without a mains grid connection. And the efficiency of the process, which uses a fraction of the energy to sustain itself, means carbon-negative hydrogen at a competitive price is achievable.

Outputs

Mix of Gases

Hydrogen

Carbon Dioxide

Biomethane

Clear Hydrogen

The initial output is a blend of gases. This mix can be used as is or split again into its component gases – hydrogen, carbon dioxide and biomethane. The process produces few tars, meaning little cleaning is needed. And splitting of the gases allows for the capture of carbon dioxide, interrupting the carbon cycle and creating carbon-negative hydrogen or Clear Hydrogen.

Applications

The potential for decarbonisation using our gas is huge.

Applications

Both syngas and hydrogen have a wide variety of applications, and the mix of gases can be tuned to a specific use. This is key to decarbonising heavy industry and energy production, much of which is heavily reliant on natural gas. Because the carbon can be captured during production – and consumption of hydrogen does not release carbon – Clear Hydrogen can take industries beyond carbon neutral and towards carbon negative, helping us to achieve net zero.
