Cryocap™ Carbon Capture Technology

A smart & innovative way to reduce the carbon footprint

Air Liquide Engineering & Construction offers environmentally-friendly technologies and applications to enable the transition to low carbon for its Customers

With the fight against Climate Change accelerating with the Paris agreement at the end of 2015, and this year's unprecedented COVID-19 crisis, various countries are moving at a much faster pace to adopt low carbon solutions. 

Air Liquide Engineering and Construction has developed a suite of robust & competitive technologies for CO₂ capture and liquefaction suitable for various industries to meet this new dynamic around CCUS projects. 

Our customized carbon capture utilization and storage solutions cover the entire value chain for producers of hydrogen, renewable fuels, methanol etc. 

One of the key technologies helping customers today is Cryocap™, a carbon capture technology that is unique in the world. 

Customers can reduce their emissions by up to 90% of C0₂ and increase production capacity by up to 20%.

Air Liquide’s journey began in 2010 with first pilot projects and accelerated in 2015 when it started operating the world’s first demonstration plant using cryogenic carbon capture technology on a hydrogen production unit in Port Jerome, France.  Following five years of successful and highly reliable operation, it has become one of the key responses to reduce CO₂ emissions of production units around the world.

Cryocap™ is a technological innovation for CO₂ capture that is unique in the world

Cryocap™ uses a cryogenic process involving low temperatures to separate gases. Cryocap™ can be adapted to specific applications combining a variety of Air Liquide’s technologies such as the capture of CO₂ from Hydrogen production units (Cryocap™ H₂) or from other industries (Refining, steel, cement,...) concentrated  flue gases (Cryocap™ FG)  or from Oxy Combustion power stations (Cryocap™ Oxy).

Cryocap technology can  support  customers  to capture up to 90% of the CO₂ of a Steam Methane Reformer while boosting the H₂  production by up to 20%. 

Today, Cryocap™ H₂ is the only technique that enables the reduction of CO₂ released during the production of hydrogen while increasing in the meantime the hydrogen production by  up to 20%. Cryocap can meet any CO₂ specification (gas or liquid) for any application (Geological storage, Enhanced Oil Recovery, Merchant market).

Cryocap™ has resulted in the filing of several patents and illustrates the Air Liquide Group’s capacity for innovation. The installation in Port-Jérôme at the largest Steam Methane Reforming Hydrogen production unit operated by Air Liquide in France represents the first industrial deployment of the Cryocap™ H₂ technology .

Since the plant started operating in 2015, its operation has proved to be extremely reliable and its integration with an existing SMR did not have any negative impact on the H₂ production itself. In the course of the last 5 years, Air Liquide has further optimized the plant operation with for example, the fast start-up automatic sequence.

Cryocap in Port-Jérôme demonstrates 5 year of reliable operation.  

The ExxonMobil group signed a long-term contract with Air Liquide for the supply of around 50 000 Nm³/h of hydrogen for its Esso refinery which is supplied today by the facility in Port-Jérôme.

Cryocap Presentation

Port Jerome is one of the 4 sites in Europe able to produce low carbon Hydrogen

Port Jerome is one of the 4 sites in Europe able to produce Hydrogen certified low carbon. It has been integrated as a pilot site for the project CertifHy, the first Guarantee of Origin (GO) platform for Green and Low-Carbon Hydrogen. 

Cryocap™ technology is the most environmentally-friendly technology and application available to service customers looking to reduce the carbon footprint of their production facilities

After developing what could be a European-wide common definition of low carbon hydrogen, the project moved on to a pilot demonstration of the GO scheme with Port Jerome being one of the selected sites. The site can now issue GO that will be traded afterwards on a dedicated platform. In addition, Biogas injection has also been tested at the site, pushing the decarbonization of the site even further. 

“Adding value for our customers, Air Liquide masters all separation technologies: absorption, membranes, adsorption and cryogenics, and are able to combine them for a better cost and site optimization”
