Supercritical Solutions

The electrochemical platform
for sustainable chemicals.

We built the world's first continuous high-pressure electrochemical reactor. The same platform makes hydrogen from water today and speciality chemicals from carbon-rich waste, with further feedstocks in development.

The platform

One reactor. An expanding set of solutions.

We use the same core reactor, adjust the feedstock and operating conditions, and unlock new applications faster each time. That is the power of our platform: one system, a growing range of industrial applications once considered too hard to scale.

The challenge

Industrial production is too fossil dependent, too complex, and too wasteful.

Essential fuel and chemical production needs to evolve. The world is electrifying, and electrochemical molecule manipulation will form the basis of our future products and systems.

Too many approaches that try to tackle this cost the earth. Solutions presented have huge costs and exploit critical natural resources in efforts to pivot from oil and gas derived molecules. All the while, ‘waste streams’ rich in carbon species are discarded.

Our solution

One electrochemical platform. More value from every feedstock.

Supercritical uses high-pressure electrochemistry to turn water and carbon-rich waste streams into hydrogen and sustainable chemicals. One core reactor, tuned for different applications, helps industrial partners reduce complexity, unlock more value on-site, and build stronger economics into the shift beyond fossil fuels.

Chemical processing moved to high pressure and temperature decades ago in pursuit of efficiency. Electrochemistry never followed. We built the reactor that does.

Future proof

This platform leverages renewable electricity and a circular ethos to enable the next millennium's fuel and chemical needs.

Maximising efficiency

We've unlocked the potential of electrochemistry, leveraging the power of pressure and temperature with a platform that offers unparalleled versatility in operation.

Planet and profit

We believe in profit and the planet. We seek circularity but not at any cost. Our platform offers operators the ability to shift away from fossil fuels without the cost.
