As Supercritical surpassed its 3rd anniversary of its incorporation, with our technology and team having taken huge leaps forward, we figured it was time for a fresh new look for our website!
If you’re a regular visitor, you may have noticed the upgrade from the Founder-designed first version of our shopfront (it’s the best website I’ve ever made! … but that doesn’t say much!). This time, we decided to stick to what we know; designing and scaling hydrogen technology, and left the web design to our trusted partners.
We’ve come a long way since that first website and that first video. What’s amazing, is the video stayed true. We produced it during the TechX accelerator with the support of the Net Zero Technology Centre within the first 3 months of Supercritical’s existence, and now it will remain a memento for the Supercritical Archives (and the Science Museum in 100 years! 😜).
The product, the vision, the value that we saw for the sector in 2020, when the Supercritical was little more than a great idea and a group of 4 determined founders, remains the same today. The difference between then and now lies in the technical progress, the commercial validation and the additional benefits that we’ve curated throughout the development process, whilst working with our customers.
In 2020, the world had never seen a continuous water electrolyser capable of operating at pressures and temperatures of supercritical water conditions. Only snippets of literature pointed to the potential. Since then, Supercritical has validated the potential of high pressure, ultra-efficient water electrolysis in the lab and has built its first out of lab demonstrator in one of largest hydrogen hubs of the UK, Teesside.
Market leading efficiencies at never before seen pressures are paving the way for a new class of green hydrogen technology, offering a step-change in levelised cost! With patents pending and feedback positive, we’re really confident in the foundation of engineering and we’re poised and prepared to commercialise the technology.
There has been no shortage of opportunities to present the value of Supercritical’s technology. With efficiency and high pressure delivery being essential to over 90% of today’s existing hydrogen demand and pivotal to almost all future demand, we’ve forged partnerships with some the world largest organisations and proven through our case studies that the technology will be a major enabler in achieving their net zero goals.
To add to these public studies, we’ve got a number of really exciting confidential collaborations bubbling under the surface. Continue to watch this space as we’re able to bring these to the fore!
We set out to increase efficiency and increase delivery pressures versus today’s incumbent technology. By doing this, by completely re-inventing the electrolyser, we’ve also given ourselves a platform to de-risk some of the biggest issues in existing hydrogen value chains.
Iridium - One of rarest metals in earth’s crust. It has chemical properties that enable the performance of technologies like Proton Exchange Membrane (PEM) electrolysers. With the scale of demand forecast for electrolysers, the cost and availability of iridium is a major risk to these supply chains. Supercritical does not require iridium to achieve its high efficiencies.
PFAS - Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) have unique and in many cases, very desirable characteristics and properties. In PEM and anion exchange membrane (AEM) electrolysers, they’re used in the membranes to enable conductivity in the system. However, one property of PFAS chemicals is that they do not naturally degrade in the environment. This means that quantities of these chemicals build up in undesirable places like water. For this reason, they’ve been nicknamed ‘Forever’ chemicals. Many of these chemicals have been identified as being hazardous to humans and the environment and as a result of this, their use in products is being debated, with a risk that they may be banned entirely. Supercritical does not use PFAS chemicals in its stack architecture.
End of Life - Green technology products are often put under the spotlight, and rightly so. Technologies often aim to do good, but bring side effects with them. Managing products at the end of their useful life is essential. Supercritical aims to be a planet first technology developer. This means decarbonising without any unnecessary harm done to the environment in other ways. By designing a technology able to operate at intermediate temperatures and high pressures, we’ve done away with nasty polymers and challenging chemicals or materials to deal with at end of life. In fact, Supercritical’s technology is almost entirely recyclable at end of life. That means sustainable green hydrogen production forever.
Reminiscing on the past always leaves me with a nice warm feeling, and I’m immensely proud of what the team at Supercritical has achieved. Looking forward on the other hand excites me, and it should excite you! The opportunity to deliver change is within our grasp and I can’t wait to report back again after we deliver our 3 year roadmap from now.
