Hydrogen power plants

When hydrogen is used to replace natural gas, combustion no longer produces direct CO2 emissions, because hydrogen contains no carbon. This is why using hydrogen can significantly reduce the carbon footprint of electricity generation.

Yes, Siemens Energy provides hydrogen upgrade concepts for existing gas-fired plants, using feasibility studies and standardized approaches to define a stepwise path from natural gas to hydrogen co-firing.

A typical Power Only package includes an H2-capable gas turbine (such as an SGT5-9000HL, SGT-800, or SGT-400) combined with the Omnivise fleet management system to integrate and control plant components.

Siemens Energy recommends a plant-specific feasibility study that assesses current capabilities, defines realistic hydrogen targets, develops a design package, and sets out a milestone execution plan aligned with decarbonization goals.

Yes, existing gas turbine facilities can be expanded with Siemens Energy electrolyzers and hydrogen storage, enabling on-site production, storage, and later use of hydrogen for power generation.

By using surplus renewable electricity to produce hydrogen, plants can store energy for later use in gas turbines, reducing CO2 emissions, lowering CO2-related costs, and creating an additional energy storage option.

No, Siemens Energy’s hydrogen power plant solutions support both new-build projects and retrofits of existing plants, with concepts that can be customized to the required capacity and site conditions.

Customers can contact Siemens Energy’s support team, which is available 24/7 in multiple languages, and request further information, a feasibility assessment, or detailed guidance on hydrogen power plant solutions.
