2 ITM Power has developed a range of materials and technologies to reduce the cost of Hydrogen production The company is developing equipment to convert renewable energy to a clean fuel; storing the energy as green Hydrogen for decarbonising transport, industrial and residential applications. ITM Power is an AIM-listed company registered in England operating in Sheffield UK. ITM has developed its own polymeric ion-conducting materials for hydrogen generation by water electrolysis. The company is developing engineering solutions for zero-carbon hydrogen generation. ITM has 5 patents granted and a further 23 in the application process. Harnessing Renewables Here is the problem. Renewable energy such as wind and solar are unpredictable and need storage technology to be fully captured and effectively utilised. How do you store electricity for long periods of time? The only answer today is hydrogen produced by electrolysis. Enabling you to: Use your renewable power whenever you need it Keep the lights 'on' during power cuts Bring power to remote, off grid locations Reduce your energy carbon footprint Green Hydrogen All fuels produce carbon somewhere in their supply chain, except Green Hydrogen which is the only clean fuel. Green Hydrogen is produced in an electrolyser by splitting water using renewable electricity. You can produce your own fuel When you produce Hydrogen the only by-product is oxygen When you use it the only by-product is water Once you have paid for the equipment your ongoing fuel is free Membrane The membrane is the heart of fuel cell and electrolyser stacks. ITM has developed and patented an entirely new range of cross-linked ion exchange membrane materials which: are a fraction of the cost of conventional fluorinated polymers lend themselves to mass production techniques enable the catalysts to be more easily recycled The majority of conventional membrane materials are fluorocarbons which are expensive and require significant chemical plant to fabricate. ITM s materials are low cost hydrocarbons made by mixing together liquid chemicals to a particular recipe. This process enables the functional properties of the material to be varied over a wide range by modifying the ratio of its constituent components. Importantly, ITM s materials contain separate hydrophilic groups which hold water within the structure, helping to regulate hydration. Hydrogen Storage Hydrogen storage is a core requirement for refuelling vehicles and for energy storage. ITM has developed systems design and integration expertise covering the compression, storage and dispensing of high pressure gaseous hydrogen up to 350 bar.

3 Electrolyser An electrolyser is a device which splits water into hydrogen and oxygen using electrical energy. When the electrical input comes from a renewable source, the hydrogen has no carbon footprint. This is the only practicable way to generate a zero carbon fuel. ITM is developing a range of self contained electrolyser systems which produce hydrogen at convenient pressures. Hydrogen production rates fall into three ranges: Small: In the region of kg/week H 2. This is appropriate for laboratory scale analytical applications, the education market and fuel cell developers and for trickle charging hydrogen stores. Medium: A minimum of 1kg/day H 2. Units in this range may be used on their own or in tandem for H 2 ome, transport and small industrial applications. Large: As required for high pressure transport refuelling and other industrial decarbonisation applications. ITM electrolysers deliver hydrogen at 15 bar which is consistent with existing propane storage technology, metal hydride storage systems and hydrogen compressors. ITM has experience of generating hydrogen directly at 75 bar, which offers a route for bypassing the need for external compression and reduces the complexity of downstream high pressure plant. ITM s electrolysers are modular, which provides flexibility and allows for easy expansion. Generation Technology Hydrogen can be used to generate electricity via a fuel cell or a conventional generator, retrofitted with hydrogen injection and engine management software. ITM has extensive experience of both engines and fuel cells in hydrogen systems designed for automotive and built environment applications. ITM have modified the petrol engine in a Ford Focus to burn hydrogen fuel. This is an additional route to costly fuel cell vehicles and provides a route for the existing vehicle stock to be decarbonised. H 2 ome ITM has designed hydrogen systems technology for integration in the built environment, to provide energy security and zero-carbon solutions for early adopters. There are four primary configurations intended for application in the residential sector: Hydrogen heat, power and cooking systems Back-up heat-and-power systems for rural and island communities Autonomous off-grid renewable heat-and-power systems for remote regions Home refuellers for hydrogen cars Each is based on a variant of ITM s self-pressurising electrolyser technology and involves on-site gaseous hydrogen storage and utilisation (either by combustion or a fuel cell). Where the intention is to achieve a zerocarbon solution, careful system sizing and the utilisation of green electricity is essential.

4 High Pressure Storage & Dispensing ITM has systems design and integration expertise covering the compression, storage and dispensing of high pressure gaseous hydrogen. This is a core requirement both for fuelling hydrogen vehicles (which employ 350 bar and 700 bar hydrogen stores) and for compact energy storage in stationary applications. Application areas include: Return-to-depot refuelling of delivery vans and buses Storage of surplus wind electricity from a wind farm Storage of off-grid electricity from a solar photovoltaic, wind or micro-hydro energy converter Cascade hydrogen storage systems for rapid refuelling At its site in Sheffield, ITM has constructed a small hydrogen refuelling station based on its electrolyser technology. This is designed to refuel 1 2 vans or cars per day with 350 bar hydrogen. It is a demonstrator intended to indicate the pathway for deploying larger return-to-depot refuellers by companies with urban vehicle fleets. Transportable Hydrogen ITM Power has taken the stationary hydrogen station and designed it into a transportable high pressure system. This can be used where there is no current hydrogen infrastructure for co-powering diesel/oil fired installations, for off-grid applications and for use in conjunction with renewable energies such as wind, micro-hydro and solar. Bespoke ITM has the design and engineering capability to tailor hydrogen systems to customer applications. System specification: matching gas production demand with generation capacity, electrical installation sizing, storage sizing to optimise performance Component design: Full CAD capability to design complete systems including graphics and animation Complete systems integration: Partnering with customers and suppliers where needed, to provide systems. Components may incorporate electrolysis, through gas compression to storage and delivery.
