Siemens will run Galp's 100 MW Sines hydrogen plant from a digital twin

8 October 2026: Siemens will digitalise GalpH2Park in Sines, Portugal, together with Galp Energia. The first phase is a 100 MW renewable hydrogen facility designed to produce up to 15,000 tonnes of renewable hydrogen a year, and Siemens estimates its control software can reduce the energy the plant uses by up to 15 percent.

Not yet independently verified. The savings and emissions figures are Siemens estimates, and the start of operation is expected rather than confirmed. We will update this when it can be confirmed, and remove this note.

A twin that predicts rather than records

The core of the project is the Siemens Hydrogen Performance Suite, or HPS. Siemens describes it as a digital cockpit built around a predictive, physics-based Digital Process Twin, a high-fidelity model that gives operators real-time optimisation rather than a history of what already happened. The stack covers process modelling, data analytics and real-time visualisation.

The release was issued from Erlangen by Siemens Digital Industries, the unit that serves process and discrete manufacturing. Siemens says that unit has about 70,000 employees and offers Siemens Xcelerator, an open digital business platform.

Connecting the plant to power markets

A hydrogen electrolyser buys electricity at a price that moves through the day, and the plant has to decide when to run. HPS connects the twin with live plant data and with external sources, including grid operators and energy markets, so the same system that models the process also supports production scheduling and energy procurement.

The power itself comes from long-term renewable supply agreements and from Galp's own renewable generation. Galp's website puts its installed renewable capacity at 2.7 GW, about 70 percent solar and 30 percent wind, after the 2026 purchase of 32 operating wind farms in Spain with more than 700 MW for EUR 740 million. It lists more than 0.2 GW in Portugal, including the 156 MW Alcoutim solar park with 5 MW of batteries.

What the plant is expected to achieve

Siemens gives the following planning figures for the site:

• output of up to 15,000 tonnes of renewable hydrogen per year
• energy savings of up to 15 percent from the optimisation software
• a cut of about 110,000 tonnes of CO2e per year in Scope 1 emissions

The plant is due to start operating at the end of this year, and only this first phase is described. Siemens expects it to be one of the largest renewable hydrogen projects in Europe.

Siemens equipment on site

Beyond the software, Siemens lists a wide portfolio for the plant: monitoring and control, industrial automation, digital twin technology, power protection and distribution, drives, electrification, instrumentation and digital services.

Siemens AG describes itself as a technology company in industry, infrastructure, mobility and healthcare, based in Berlin and Munich. For the fiscal year ended 30 September 2025 it reported revenue of EUR 78.9 billion and net income of EUR 10.4 billion, with about 318,000 employees.

Galp's hydrogen work

Galp says it is committed to leading green hydrogen production through electrolysis, with work on new technologies, process optimisation, storage to manage the intermittency of renewables, and transport methods for decarbonising industry. It runs Id.Lab, its research centre for industrial decarbonisation, with operations in Sines and at the Federal University of Rio de Janeiro.

Axel Lorenz, Executive Vice President Automation Process Industries at Siemens, says: "GalpH2Park is a lighthouse for Europe's energy transition." He adds that digital innovation is the key to making renewable hydrogen economically viable.
