ITM Power is an AIM-listed company incorporated, registered and operating in England. We have a first-class team of engineers and scientists, based at two facilities in Sheffield, in the United Kingdom. ITM Power has both a strong base of intellectual property and engineering expertise for providing complete hydrogen solutions and CE marked products for sale. ITM Power designs and manufactures Hydrogen Energy Systems for Energy Storage and Clean Fuel production. The HFuel system is based on ITM’s PEM electrolysis technology, the system is capable of generating hydrogen and contains the necessary equipment to purify, compress, store and dispense hydrogen gas to hydrogen fuel cell vehicles. The HFuel systems are packaged in standard ISO shipping containers and controlled via PLC. The core hydrogen generation module is based on a number of PEM electrolyser stacks. Hydrogen can be generated at a pressure of 20bar (options allow up to 80bar). Gas drying equipment is included enabling the output gas to conform to the standards required for use in hydrogen fuel cell electric vehicles (FCEV). The refuelling module compresses the hydrogen gas and fills a high pressure store which supplies gas to the SAE J2601 compliant refuelling nozzle. HFuel systems are available in a range of sizes and capacities, ranging from small systems suitable for refuelling small fleets and for use at depots, through to large refuelling stations suitable for use as part of a national infrastructure. The integrated system is CE marked and is installed in accordance with all relevant codes and standards. The HFuel systems are supplied with training materials, declaration of conformity and user manual. HGas brings together rapid response and self-pressuring PEM electrolysers into MW scale integrated packages, generating hydrogen at pressures suitable for either direct injection into natural gas networks or via methanation processes without additional compressions. A modular philosophy allows 1MW of electrolysis to be accommodated within standard ISO containers. ITM has power to gas electrolysers deployed in Germany, and is developing projects in the UK and across Europe and the US. As well as providing hydrogen plant, ITM also has experience all aspects of deploying hydrogen systems.

Linde is a leading global industrial gases and engineering company with 2019 sales of €25 billion. Linde operates a Test and Calibration laboratory according ISO 17025 and an ISO 17034 production for secondary Standards and Reference Materials. We support high-quality industrial laboratories and industry with accredited mixtures. 

In combination with a huge knowledge in producing of gas mixtures from about 500 available components in a ppb to % range, we cover a broad portfolio of analytic measurements in our laboratories. Our experience in producing and analysing gas mixtures in the low ppb to ppt level is a key for a qualified research of impurities in hydrogen. As example we have and still develop unique measurement methods (Ion chromatography and high pressure FTIR). In combination with well-known measurement systems (electrochemical cell, SCD (Sulphur chemilumiscence detector), GC’s, UV-VIS, acoustic detector, cavity ring down) it is possible to measure impurities in hydrogen for our quality control as well as for the high purity hydrogen 7.0 quality for semi conduction industry in past and future. 

Pre-treatment of cylinders is a crucial part of the production of stable mixtures, especially on low concentration levels of reactant components. Therefore, Linde aims at improving the pre-treatment methods as well as the properties of the cylinder surface. We established an advanced method for automated cylinder pre-treatment by applying temperature and pressure to achieve reliable results. As a next step a novel coating plant is under development for minimising the interaction between component and cylinder wall.

Linde will be involved in quality control (WP2) and sampling (WP3).
