Hydrogen produced from renewable electricity substitutes fossil fuels and substantially lowers CO2 emissions across all sectors. As industrial feedstock, hydrogen is used for the refining of crude oil, iron and steelmaking as well as the production of fertilizers and of numerous chemical products. As energy carrier, renewable hydrogen decarbonizes mobility, power and heat supply.
Hydrogen Electrolysis solutions
Sunfire’s HyLink electrolyzers are the optimal solution for your renewable hydrogen project. Based on Alkaline and solid oxide (SOEC) technologies, our electrolyzers are tailored to the unique requirements of your industry and local environment. Whether as standalone or hybrid electrolysis solution, we turn your hydrogen plans into reality.
Sunfire’s high temperature, solid oxide cell electrolyzer is the superior electrolysis solution for industrial applications when steam is available. Running at 850 °C, our SOEC utilizes industrial off-heat to process water steam to hydrogen at highest conversion efficiencies.
The electrolyzer follows a modular system design. One system produces 750 Nm³/h hydrogen with a power consumption of 3.6 kWh/Nm³.
+ Steam electrolysis: Utilization of industrial off-heat as steam reduces electricity demand
+ Efficiency: Market-leading efficiency (84 %LHV TO AC) yields lowest hydrogen costs
+ Reliability: Certified electrolyzers with proven long-term operation
+ Flexibility: Modular design simplifies scaling to any desired electrolysis capacity
+ Sustainability: No use of PGM-based materials in electrolyzer production
Sunfire’s ultra-reliable pressurized Alkaline electrolyzer is optimal for applications without or with limited steam availability. With a proven system lifetime of at least 90,000 operating hours, the electrolyzer is our established solution for renewable hydrogen production.
The electrolyzer has a scalable system design. One system produces 1,065 Nm³/h hydrogen at 30 bar(g) with a power consumption of 4.7 kWh/Nm³.
+ Robustness: Proven technology with demonstrated system runtime of more than 20 years
+ CAPEX: Lowest electrolyzer costs reduce capital requirements
+ Pressure: Renewable hydrogen is delivered at a pressure of up to 30 bar(g)
+ Scalability: Modular 5 MW stack design enables effective scaling to large electrolysis capacities
+ Adaptability: Easy integration into any environment – whether industrial or greenfield
Hydrogen is used in industrial refining processes to produce conventional liquid fuels such as jet fuel, diesel and gasoline. Renewable hydrogen substitutes hydrogen produced from natural gas via steam reforming.
Renewable hydrogen will transform today’s carbon-intensive primary steelmaking process via the blast furnace route using coal to a hydrogen-based direct reduction route. At same time, renewable hydrogen substitutes hydrogen produced from fossil sources in existing processes.
Hydrogen is a fundamental feedstock in the chemical industry. It is a basic component for the production of ammonia and serves as a key element for the production of methanol, which can be further processed into fuels or polymers. Renewable hydrogen substitutes hydrogen produced from fossil fuels – significantly lowering CO2 emissions of chemical production plants.
Renewable hydrogen used in fuel cell electric vehicles is a net-zero mobility solution. With a growing network of refueling stations, it is a highly effective solution to replace fossil fuels across a wide range of applications. Especially for heavy-duty vehicles like trucks, busses and trains, renewable hydrogen is the future.
Power and Heat
For large-scale power and heat supply, hydrogen produced from renewables is a clean energy source. It can be stored temporarily, transported in gas grids and reconverted into electricity, e.g. in fuel cell power plants or gas turbines. Substituting natural gas as energy carrier for buildings, power plants or industries, renewable hydrogen contributes to substantial CO2 emission savings in the energy sector.
Sunfire is providing tailored electrolysis solutions for innovative renewable hydrogen projects. We are currently realizing projects together with our industry partners Neste, MPREIS, Salzgitter and Total.
Our partner Neste aims at decarbonizing all activities until 2035. The project marks the first implementation of a Sunfire-HyLink SOEC electrolyzer at multi-MW-scale (2.6 MW). The electrolyzer will supply renewable hydrogen to Neste’s refinery in Rotterdam as a replacement for hydrogen produced from fossil natural gas.
In the project Demo4Grid, funded by the EU and Switzerland, a Sunfire (IHT) alkaline electrolyzer (4 MW) will be installed at the MPREIS food production center in Völs, Tyrol. It will supply hydrogen for a fueling station and for heat supply to the bakery. In addition, the system will provide grid balancing services under real operational and market conditions.
The steel project marks the first implementation of Sunfire-HyLink SOEC electrolyzer at large-scale in an industrial environment. Until the end of 2022, the electrolyzer will produce renewable, high-purity hydrogen that will be used for annealing processes in Salzgitter’s integrated steelwork as a replacement for hydrogen produced from natural gas.
Our project with Total heralds a new era for the industrial production and use of renewable hydrogen and methanol in refineries. The implementation of a Sunfire-HyLink SOEC electrolyzer marks the first step for the industrial-scale production of synthetic methanol from renewable hydrogen and industrial concentrated CO2.
