1 IF THE FUTURE COULD CHOOSE

2 WORLD CLASS ELECTROLYSERS NEL A electrolysers, hydrogen plants based on water electrolysis technology with atmospheric pressure, are considered world class. With more than 85 years of experience in the field of electrolysis together with sustained efforts in research and development, we have managed to reach today s unique technology. The NEL A electrolyser is well recognised for its robustness, reliability and energy efficiency. With these features our technology sets a benchmark for others to follow. Add flexibility, ease-of-use, high-capacity and safety to your list of decisive criterias, and you will find that we provide a solution second to none. RELIABLE H2 SUPPLY Independence With our on-site electrolyser plant, you are in control of your own supply of hydrogen Reliable production The most proven electrolyser technology on the market. Designed over decades for unmanned, reliable and problem-free production of hydrogen. Continuous production Non-stop production for years without any need for maintenance shut-down. A replacement of the cell stack would typically be required after approximately 10 years. Variety of applications - From edible oil to float glass and galvanizing steel lines, NEL A electrolysers serve a number of applications where the hydrogen is highly critical for the process of the plant. HIGH FLEXIBILITY H 2 on-demand Quick start-up and shut-down of the plant allows for hydrogen production according to demand. Operational range Automatically adjusted production between 20 and 100% of the installed capacity. Upscale of capacity The modular concept may be pre-designed for future expansion of capacity. COST-EFFICIENT SOLUTION Energy efficient - The NEL A electrolyser use a special catalytic coating that provides the most energy efficient electrolyser in the market, reducing the operating costs to a minimum. Labour efficient With our advanced PLC control system, the plant runs automatically and unattended. Only routine shift inspections are required. Maintenance efficient The plants are designed for minimum maintenance, with annual maintenance costs typically being only 1-2% of the total investment. Lifetime Efficient NEL A electrolysers have a lifetime of years - or even more. This makes the total lifecycle costs of our plants competitive with any hydrogen sourcing alternative.

4 IF THE FUTURE COULD CHOOSE THE WORLD IS CHANGING. The worldwide increase in energy demand, combined with the challenge of reducing the greenhouse gas emissions, will have an effect on our future energy supply.

5 If the future could choose, hydrogen will play a major role in the future energy society, either as a fuel, or as intermediate storage of energy in integrated, renewable energy systems. NEL Hydrogen is committed to provide technology that enables solutions for the future. This is well demonstrated by the launch of the new electrolyser model NEL P 60. It provides unique technological features in terms of operational flexibility making NEL P 60 the ultimate choice for new concepts in the energy sector: Power-to-Gas (PtG) - Providing added value for renewable energy plants by utilising excess energy to produce hydrogen as storage medium for energy for later alternative use. Hydrogen Fuelling Stations - Providing clean fuel to the transport sector through a complete on-site 130 kg/day hydrogen plant supplied as a turn-key, compact 20 foot container solution.

6 EXTREME FLEXIBILITY NEL P 60 is a compact, high pressure electrolyser that provides a technological breakthrough in terms of operational flexibility. NEL P 60 has an exceptional dynamic operating range between 10% and 100% of the installed capacity while maintaining high gas purity. The hydrogen production rate responds immediately to rapid changes in power input. Additionally the electrolyser can be put in stand-by mode for long periods, allowing instant resumption of hydrogen production when required. This extreme flexibility makes NEL P 60 ideal for integration with renewable power sources and industrial applications with variable hydrogen demand. KEY CHARACTERISTICS Compact turn-key hydrogen plant delivered as containerised solution or skid-mounted for indoor installation High pressure 15 bar g outlet pressure directly from the electrolyser Capacity 60 Nm 3 /hr production from one single cell-stack Reliability & Maintenance highly reliable electrolyser designed for automatic operation with minimum maintenance Extremely flexible operation - operational range % - automatic continuous stand-by operation - response time < 1 second
