4 ITM Power Product Guide INTRODUCTION ENERGY STORAGE CLEAN FUEL ITM POWER ITM Power offers a broad range of electrolyser products covering a variety of applications from small scale energy storage to large scale clean fuel generation. At the heart of every electrolyser system is a stack. This key component provides the mechanical and electrical environment where water is split into hydrogen and oxygen. Through intensive testing programmes, ITM Power has developed a suite of robust stack platforms achieving the right balance between innovation and engineering experience. In addition to the stack, an electrolyser product requires numerous additional elements including dedicated balance of plant, control system, power system and packaging. All of this must be brought together as a compliant system in order to gain the CE mark required for commercial sales within the EU. PRODUCT COMPLIANCE POWER SYSTEM STACK WATER SYSTEM The ITM Power team has delivered a suite of compliant electrolyser products ranging from off-grid hydrogen generators to fully integrated vehicle refuelling plant.

5 revenue: grant funding status Markets and Applications ITM Power is engaged in a range of large scale hydrogen generation applications. These include 100% hydrogen solutions (e.g. vehicle refuelling), applications where a hydrogen/natural-gas mix is utilised (e.g. Power-to-Gas and co-firing) and the production of derivative fuels and chemicals (e.g. synthetic natural gas and ammonia). Partnerships are being developed and sought in these areas. FUEL GENERATION Stack / Control / BoP COMPRESSION AND STORAGE DISPENSE Hydrogen is the fuel required by fuel cell cars (FCEVs). ITM s refuellers generate, purify, compress, store and dispense hydrogen at hydrogen refuelling stations (HRS) designed for both individual vehicles to country-wide infrastructure. POWER-TO-GAS GENERATION Stack / Control / BoP GAS MIXING GAS INJECT An electrolyser s ability to absorb renewable power and convert it to hydrogen for use in heating applications provides the platform for a Power-to-Gas system. The generated hydrogen may be injected into the natural gas grid and the mixture utilised by conventional burners and appliances. CO-FIRING GENERATION Stack / Control / BoP GAS MIXING BURN Hydrogen may be combusted as a mixture with natural gas (or biogas), or alongside conventional gas burners, to satisfy a heating requirement. These co-firing approaches can be applied to various industrial heating applications to reduce their carbon footprint. SNG GENERATION Stack / Control / BoP METHANATION GAS INJECT A power-to-gas system may be configured to use a waste CO 2 stream and hydrogen to produce synthetic natural gas (SNG) by methanation. This may be injected into the natural gas grid and so reduce our dependency on imported gas. AMMONIA GENERATION Stack / Control / BoP HABER-BOSCH FERTILISER Hydrogen may be combined with atmospheric nitrogen to produce ammonia. Renewable ammonia derived from electrolytic hydrogen enables fertilisers to be produced locally in agricultural regions eliminating the requirement for fertiliser deliveries and lowering the carbon footprint. 5

6 ITM Power Product Guide HPAC A flexible mid-size hydrogen generator HPAC The HPac product platform offers flexible mid-range hydrogen generation. Available in two standard sizes, HPac delivers hydrogen at 15 bar pressure and is capable of generating between kg/24hrs. Based around ITM s well proven stack technology, the system operates under differential pressure to minimise plant cost and promote hydrogen purity. Operation is via a simple push button interface but can also be configured for control via inputs from other systems making it well suited to integration projects. Available with a range of gas purification options, HPac is capable of producing hydrogen of the right grade for a wide range of fuel cell and industrial applications. HPac 10 and 40 both carry a CE mark of conformance and are Made in Sheffield. 6

10 ITM Power Product Guide HFUEL A REVOLUTIONARY VEHICLE REFUELLING SYSTEM HFUEL ITM Power s Transportable Hydrogen Refuelling Station (HFuel) is a self-contained module suitable for refuelling hydrogen-powered road vehicles and forklift trucks. HFuel is well suited to small fleet and early hydrogen highway applications of both fuel cell and hydrogen engine vehicles (FCV and HICEV). It is based around a modular platform (standard freight containers) and can be expanded at any point after the initial installation enabling a staged roll-out of hydrogen fuel. HFuel generates hydrogen by electrolysis, compresses it, stores it and dispenses the gas on demand at high pressure (nominally 350 bar/35mpa). It requires an on-site water and electricity supply but is otherwise an autonomous solution for refuelling hydrogen-powered vehicles. Zero-Carbon Fuel Because HFuel is based on an electrolyser it is uniquely able to produce zero-carbon hydrogen if linked to a renewable power source or a supply of green electricity. The fuel delivered to the vehicle is then carbon-free and no atmospheric carbon emissions result from its use. HFuel provides a pathway for eradicating emissions associated with light duty commercial vehicles and materials handling in warehouses and factories. Unlike battery recharging stations HFuel enables the user to quickly recharge a vehicle to 100% capacity. This enables hydrogen to be used to decarbonise return-to-depot and shift work vehicles that have a higher daily mileage requirement. 10

12 ITM Power Product Guide HGas Enabling Technology for MW Scale Energy Storage Hgas ITM s HGas product brings together rapid response and self-pressurising PEM electrolysis into a fully integrated package. Capable of addressing MW scale applications, HGas accommodates fluctuating power profiles while generating hydrogen at pressures suitable for either direct injection into natural gas networks or via methanation processes without additional compression. As the shift from fossil fuel to renewable power generation continues, the need for large scale and long-term energy storage grows rapidly. The fact that renewable power is often intermittent and therefore difficult to apply directly to traditional storage technologies makes this challenge even more acute. Rapid response electrolysis offers an effective route to assimilate renewable power and convert it to hydrogen which can be stored for long periods for subsequent use as a fuel for heat, mobility or power generation. Power-to-Gas is a methodology of introducing such hydrogen to the natural gas network, essentially converting renewable electrical power to a clean gas that can be more conveniently stored using existing assets. There are two main Power-to-Gas mechanisms. The first involves metering pressurised hydrogen into the gas network directly. The second involves combining hydrogen with carbon dioxide via a methanation process to produce synthetic natural gas prior to introduction to the grid. HGas is a product designed specifically for power to gas applications and is capable of self-pressurising up to 80 bar and responding in 1 second. The modular philosophy allows up to 1MW of electrolysis to be accommodated within one 20 foot shipping container. 12
