Pioneering hydrogen technology for a life beyond fossil fuels.

We partner with industry to move and think beyond fossil fuels with innovative clean technology solutions.

Proud to be partnered with

developing the world’s first high pressure, ultra-efficient electrolyser for the production of hydrogen with zero emissions.

High pressure

Save on CAPEX and complexity, increase system reliability with Supercritical’s high pressure electrolyser. All major hydrogen markets stand to benefit from our game changing approach.

220BARA HYDROGEN
99% efficiency

Ultra-efficient

The cost of renewable energy is the single biggest contributor to the cost of green hydrogen. By operating at 99% Higher Heating Value (HHV) efficiency in the stack, we will deliver step change benefits in the levelised cost of hydrogen.

planet first

We’re developing a zero emission hydrogen production technology and doing it without the use of scarce critical materials like Iridium, PFAS chemicals (forever chemicals) and rare earth metals.

Planet first

We’re developing a zero emission hydrogen production technology and doing it without the use of scarce critical materials like Iridium, PFAS chemicals (forever chemicals) and rare earth metals.

Current technologies are not working. They are too expensive, contaminate our planet and are built on high risk supply chains.

Inefficient with only marginal gains projected

Incumbent electrolyser technologies have been in development for 100 years in some cases. Demand has changed due to the climate crisis, the technology has remained stagnant.

Deliver low pressure gases

Production of green hydrogen is the hot topic of today. Tomorrow it will be compression and storage. Supercritical’s technology tackles the sector’s two biggest problems in one.

Built on high risk supply chains

The use of scarce critical materials like Iridium and rare earth metals, and utilising PFAS (forever) chemicals, existing tech is struggling to scale!

A new class of electrolyser

Membraneless

Membranes are hard to handle and make manufacturing yields low and costs high. They are the first point of failure in the stack, and it will happen with no warning. Supercritical’s novel cell assembly negates the need for a membrane entirely - offering low costs and high reliability.

Uses no rare earth metals, forever chemicals or iridium

Our technology is built from mass manufactured industrial metals. They are produced at scale, today, for hundreds of applications.

All metal design with easy end of life recycling that uses existing processes

Ever wondered what happens when clean energy technology reaches the end of its life? We have. No more debates about toxic waste or products to landfill. We’ll be recycling our tech to produce more electrolysers.

High pressure, high purity hydrogen

220bara high purity (up to 99.999mol%) hydrogen plugged straight into your downstream processes.

High pressure, high purity oxygen

Compressing oxygen is really challenging too. Oxygen at high pressures, with rotating equipment and lubricants leads to a recipe for disaster! We have a hugely valuable by product in our 220bara oxygen stream.

Refineries of the future. Harnessing renewable energy, air and water.

Long chain hydrocarbons can be produced through chemical synthesis processes, converting CO₂ (captured from the air) and hydrogen (made from splitting water) that mimic the fossil fuels that our lifestyles have become so accustomed to.

Give CO₂ value

Convert CO₂ to CO with H₂ through the reverse water gas shift reaction.

Synthesise e-fuels

Stop the world’s relentless mining of fossil fuels and deliver a net zero, sustainable carbon cycle.

DECARBONISE THE EXISTING HYDROGEN MARKET: 1  BILLION TONNES OF CARBON reduction OPPORTUNITY.

Over 90% of the world’s hydrogen demand today requires hydrogen at pressure. Industries like ammonia production, refineries and methanol production all require pressure in their chemical processes.

Meet the sub $2 price target

Supercritical’s ultra-high efficiency enables the lowest cost of high pressure green hydrogen.

Meet the high pressure requirements

Hydrogen compressors are an operator’s worst nightmare. Negate the need for them entirely with our high pressure electrolyser.

BRING ZERO-EMISSION LOW COST FUEL TO THE BIGGEST INDUSTRIAL CARBON EMITTERS

Up to 20% of the world’s industry won’t be decarbonised with electricity directly. Achieving high temperatures in industries like Steel, Cement, Glass is simply not possible without the burning of a fuel... running 24/7!

Who’s scared of Bigfoot!?

To run green hydrogen 24/7, you can’t avoid storage. Footprint is important. Whether its vessels or salt caverns, high pressure is the solution.

Heat but hotter

Supercritical produces oxygen at high pressure too. Oxy-fuel combustion is eminently possible with ease of HP gas storage.

Partner testimonials

“ Supercritical Solutions; great company, great people, great technology, but on the other hand I think it’s an enabler to hydrogen economy”

Joep Huijsmans

General Manager Power, Shell
“Performing water electrolysis at supercritical conditions is a very innovative idea. The incredibly knowledgeable team at Supercritical are brilliant at tackling the challenges this technology presents and always a pleasure to work with.”

Graham Smith

Hydrogen Technology Lead and Principle Research Scientist
“The UK is truly leading the world in hydrogen innovation thanks to the exciting efforts of companies like Supercritical Solutions. The government support which they have received today will help to boost the development of hydrogen as the clean, affordable, homegrown superfuel of the future.”

Greg Hands

Energy Minister
"Supercritical was a finalist in our Hydrogen Hypothesis Challenge for their technology. They were selected to take part in the Think & Act Differently (TAD) accelerator program to demonstrate the safe and effective use of hydrogen in a mining context, with the aim of providing insight into how Hydrogen can be used to support zero or low carbon processes. Supercritical were chosen because they proposed an idea with potential to demonstrate the value Hydrogen technologies and applications could create for our industry."

FAQs

Is a compressor needed for the electrolyser?

Supercritical doesn’t need a hydrogen compressor so long as the end use of the storage pressure is <230bara. By pumping our feed water and operating our systems at pressure, we’re able to produce hydrogen and oxygen at high pressure without hydrogen gas compressors.

For applications requiring pressures in excess of this, we are exploring higher pressure operating conditions! But whilst they are in development, our higher pressure users will benefit from significantly less compression and cooling cycles to achieve their higher pressures with gas compressors.

What happens to Supercritical’s electrolysers at its end of life?

Supercritical is the only electrolyser on the market which is almost entirely recyclable. Supercritical’s all metal design lends itself to today’s established metal recycling methodologies, meaning at end of life, when we replace our electrolysers, we need not dip into the world’s natural resources again!

Is the electrolyte that Supercritical uses for its electrolysers environmentally friendly?

Any spent electrolyte from Supercritical’s system will be dealt with in a responsible manner. Supercritical is utilising chemistry that is very common in industry with established treatment technologies, meaning that we’ll be able to treat and re-use our electrolyte at scale.

What is the hydrogen purity from the Module?

Supercritical is developing its systems to deliver up to 99.999mol% purity hydrogen. This purity meets the quality required for ammonia synthesis and also surpasses hydrogen Grade D under ISO 14687, making it suitable for fuel cells and the majority of other applications.

What is Capacity Factor?

Capacity Factor is a term used to represent the average usage, based on the maximum available, over a period of time. It is expressed as a % of the maximum capacity.

For example, solar renewable energy has a low capacity factor as they peak around the middle of the day and there are shorter days with sunlight in the winter.  Depending on the system deployed and geography, solar capacity factor is typically 15-30%.  Peaking at up to 100% in the middle of a summer day but 0% at night.

Onshore wind  has a typical capacity factor between 25% to 45% with offshore farms often benefiting from stronger and more consistent wind resources, resulting in average capacity factors that can exceed 50% in favourable locations.

You can combine Solar and Wind renewable energy technologies, as they are typically quite complementary and can increase your capacity factor by 5-10%.
