HANNOVER MESSE 2025 will shape the future of industrial energy supply. The lead theme “Energizing a Sustainable Industry” brings together numerous manufacturers and solution providers from the fields of hydrogen and fuel cells, Energy 4.0 and power engineering. Visitors from industry, science and politics gain an in-depth understanding of topics such as digitalization, decarbonization, energy efficiency, electricity self-generation, cost reduction, price volatility, and resilience.
HANNOVER MESSE 2025 drives the development of industrial energy supply: from 31 March to 4 April, exhibitors in the exhibition area “Energy for Industry” – which includes Hydrogen + Fuel Cells EUROPE, Europe’s leading hydrogen event – present the latest products and services in the sectors Hydrogen and Fuel Cells, Energy 4.0 and Power Engineering. The energy halls feature exhibits, presentations and networking events and showcase the latest technical solutions for energy generation, management, distribution, and storage.
“Energy efficiency and resilience are at the forefront of the manufacturing industry. At HANNOVER MESSE, exhibitors show modern and robust energy systems for industrial applications. Only here can visitors experience the latest high-tech solutions for themselves,” says Basilios Triantafillos, Global Director Trade Fair and Product Management at HANNOVER MESSE. “In one place, they find everything they need for a sustainable energy supply – from individual components and parts to using big data to optimize energy flow and the application of artificial intelligence.”
International corporations, small and medium-sized enterprises and startups from all over the world exhibit at the Energy for Industry area. They include such familiar names as GP Joule, Janitza, Wöhner, PreZero and EMKA as well as large group exhibits from Baden-Württemberg, Schleswig-Holstein, Brandenburg and the European Union.
Hydrogen: energy source of the future
HANNOVER MESSE 2025 highlights hydrogen’s key role in decarbonizing industry and creating a sustainable energy future. Hydrogen is a versatile energy carrier with a wide range of industrial applications, for example to make processes emission-free or to increase energy efficiency. Producers and users meet in Hannover to launch projects and discuss the necessary framework for developing a viable hydrogen industry. Visitors discover a wide range of technologies and processes, from green hydrogen production to fuel cell technologies to infrastructure projects.
Hydrogen + Fuel Cells EUROPE in Hall 13 is the heart of the hydrogen community at HANNOVER MESSE. In addition to the exhibitors, two forums feature moderated interviews and discussions as well as technical presentations.
Energy 4.0: digital evolution of the energy sector
Energy 4.0 represents the integration of digital technologies into the energy industry. At HANNOVER MESSE, exhibitors present products and solutions that address specific challenges related to the efficiency and sustainability of energy generation and distribution.
“Integrating applications such as real-time data management, smart sensor technology and software-based data analysis enables energy-consumption monitoring, cost optimization and reduction of carbon emissions. Companies can not only enhance their energy efficiency, but also adapt to fluctuations in energy demand and optimize the use of renewable energies,” explains Triantafillos.
The Energy 4.0 Conference Stage spotlights practical solutions for stable and resilient energy supply in industry with an emphasis on complete energy systems. The daily program includes keynote speeches, lectures and panel discussions on topics ranging from energy generation to usage optimization to efficient storage. Co-organizers are the German Engineering Federation (VDMA), the German Association for Electrical, Electronic & Information Technologies (VDE) and the German Electrical and Electronic Manufacturers’ Association (ZVEI).
Power Engineering: focus on efficiency and sustainability
The continued advancement of power engineering is essential for the future of industry. At HANNOVER MESSE, exhibitors present cutting-edge technologies for generating, storing, and distributing energy and demonstrate how modern power engineering innovations – such as advanced transmission systems, battery storage, and smart grids – can boost efficiency and reduce carbon emissions.
The Energy Technical Forum covers the development of robust energy infrastructures. Companies show concrete application examples, from decarbonized electricity and heat supply to mobility for industrial use. Experts from industry and academia meet to discuss the latest developments and their implications.
Compressed Air & Vacuum Technology
The compressed air and vacuum technology sector will once again be represented at HANNOVER MESSE 2025. The “Compressed Air & Vacuum Technology” exhibition area is located in the immediate vicinity of the Hydrogen Hall 13, emphasizing the synergies between the two industries. In particular, many suppliers who are experts in optimizing compressed air and vacuum technology in manufacturing also offer solutions for the growing field of hydrogen energy and storage.
