Nel leads on automation with the world’s first fully automated electrolyser gigafactory at Herøya and setting a benchmark for Industry 4.0 manufacturing in Europe.

Siemens Energy is one of the world’s leading energy technology companies. The company works with its customers and partners on energy systems for the future, thus supporting the transition to a more sustainable world. With its portfolio of products, solutions and services, Siemens Energy covers almost the entire energy value chain – from power and heat generation and transmission to storage. The portfolio includes conventional and renewable energy technology, such as gas and steam turbines, hybrid power plants operated with hydrogen, electrolysers and power generators and transformers. Its wind power subsidiary Siemens Gamesa makes Siemens Energy a global market leader for renewable energies. An estimated one-sixth of the electricity generated worldwide is based on technologies from Siemens Energy. Siemens Energy employs around 104,000 people worldwide in more than 90 countries and generated revenue of €39.1 billion in fiscal year 2025. Siemens Energy, together with its joint venture partner Air Liquide, operates a gigawatt-scale production facility for PEM electrolyzers in Berlin to serve the international market.

Sunfire is a global leader in the production of industrial electrolyzers based on pressurized alkaline and solid oxide (SOEC) technologies. From its roots in Dresden, Germany, the company has grown into one of the world’s leading electrolysis specialists. Today, with more than 700 employees from 25 nations and gigawatt-scale manufacturing capacity in Germany, Sunfire’s electrolyzers are already operating across Europe, enabling energy companies, refineries, and steel producers to decarbonize. With an order book exceeding 800 MW, landmark projects with partners such as RWE, Repsol, and Uniper, Sunfire has become an established driving force in the global hydrogen industry. The company embodies a new industrial generation: technology developed and produced in Europe, and high-quality jobs created locally - particularly in Eastern Germany.

Topsoe is a leading global provider of advanced technology and solutions for the energy transition. Built on decades of scientific research and innovation, Topsoe works with customers and partners to drive energy resilience and to achieve their sustainability goals. With an average of 8-10 percent of annual revenue invested in research and innovation, Topsoe is at the forefront of the most advanced technologies for fuel and chemical production. One-third of the world’s hydrogen production and sustainable aviation fuel operating capacity is based on the company’s technology. Topsoe offers the advanced solid oxide electrolyzer cell (SOEC) technology for the highly efficient production of green hydrogen. The technology enables the production of more hydrogen per unit of power input than conventional technologies, achieving around 20% higher efficiency, which can increase to 30% with steam integration. In late October, the company inaugurated Europe’s largest SOEC manufacturing facility. Headquartered in Denmark, the company has over 2,800 employees serving customers all around the globe.
