Hydrogen for energy
Creating the hydrogen economy of the future
At Siemens Energy, we are working closely with partners from government, academia, and industry to create a hydrogen economy that is sustainable and profitable in the long term.Our team of experts develops and integrates technologies to cover the entire hydrogen 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.
We are excited to see what this hydrogen economy of the future will look like, and we will be at the forefront of it every step of the way.
Siemens Energy and Air Liquide asked the question: What does it take to make Europe's Energy landscape fit for the future?
Hydrogen as an energy carrier for sustainable economy
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.
Hydrogen as a key energy carrier will play a major role to reach net zero CO₂ emissions in the future for those sectors in industry, mobility and energy that cannot be decarbonized by electrification
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 resources in a chemical form for long-term storage and use, with green hydrogen and its derivatives as the core component.
Green hydrogen has many uses
Green hydrogen is versatile and can be applied in different sectors.- It can be converted back into electricity through re-electrification in gas turbines, engines, or fuel cells.
- Green hydrogen can also be used to produce various types of synthetic fuels like e-kerosene, e-methanol, and e-gasoline, which support the decarbonization of the aviation, shipping, and transportation industry.
- In energy-intensive industries like steel production, it can replace gray hydrogen and other substances directly.
How is green hydrogen produced?
Hydrogen is often described with colors such as green, blue, and grey. These color codes indicate the source or process of its production. So, what are they?
Join us in shaping the hydrogen economy
There are already a number of technologies available for the production and use of green hydrogen. To make them economically and efficiently viable, they must be further developed and scaled up under real-world conditions.We are actively tackling this challenge.
To accelerate the decarbonization of the entire energy system, we intend to keep developing our hydrogen portfolio, including the industrial-scale Proton Exchange Membrane (PEM) electrolyzers and hydrogen-ready gas turbines.
With innovative solutions and services, we support and assist the production, storage, and distribution of hydrogen for our customers.
