Hydrogen for energy
Hydrogen for a sustainable and secure energy transition
Combating climate change requires the decarbonization of economic systems worldwide including all carbon-emitting sectors. More and more countries, regions and companies are committing themselves to climate neutrality and see hydrogen as key energy carrier to reach net zero CO₂ emissions in the future for those sectors in industry, mobility and energy that cannot be decarbonized by electrification.These benefits position clean hydrogen as a central vector, capable of connecting all carbon emitting sectors. It will thus shape and accelerate the transition into a carbon free energy society and economy.

Hydrogen compression – An integral part of the H₂ value chain
Hydrogen plays an essential role in a wide range of industrial applications and is increasingly becoming a decarbonization agent for the energy transition. Compression is the enabling technology for safe and cost-effective transport, storage and use of hydrogen throughout the value chain. This white paper explores the challenges of H2 compression and outlines its applications.
"In answering the question of how we can meet the world’s growing energy needs while protecting the climate, hydrogen will be an important lever. It allows to decarbonize different sectors and to transport or store renewable energy. At Siemens Energy, we will continue to drive the development of a hydrogen economy."
Christian Bruch, CEO Siemens Energy
Technologies of the future are not new to us. We have been working with hydrogen for decades. This makes our solutions proven and safe and makes us reliable technology and integration experts for all H2 application areas.
With continuous investments and proven experience in developing diverse turnkey solutions in the energy sector worldwide, we are a reliable partner across the entire hydrogen value chain – today, tomorrow and in the future.
We aim to lead the energy transition with renewable and low-carbon hydrogen solutions, including one of the world's largest Proton Exchange Membrane (PEM) electrolyzer expected to reach 1 gigawatt by 2030 and hydrogen-ready gas turbines.

World first Hydrogen Readiness certification, awarded to us by TÜV SÜD
This is an important milestone in the transition from natural gas towards hydrogen fuel for gas turbine-based power plants.
The journey starts with being H2-Ready.

Sector Coupling and Power-to-X – Climate-neutral energy
Sector coupling is the energetic link of sectors like power, energy, mobility, industry or building. It acts as a link between renewable energy sources (wind, solar, water...) and consumers.
Power-to-X as the key technology in sector coupling allows us to transform and save energy from renewable ressources in a chemical form for long-term storage and use, with green hydrogen and its derivatives as the core component.
We want to decarbonize the energy systems of the future with all our might. Governments around the world have started to develop hydrogen strategies and appropriate policies.
As a competent partner, consultant and innovator with deep expertise in the field of energy, we build and shape the hydrogen economy from the very beginning. We develop and integrate technologies to cover the entire end-to-end value chain – from wind parks through power transmission, large-scale industrialization of water electrolysis, as well as compression, transport, storage and hydrogen-based power and heat generation.
To create a hydrogen economy that is sustainable and profitable in the long-term, we are working closely with partners from government, academia and industry.
