Clean energy, sustainable chemical processes
The process industries are under pressure to move towards zero carbon products and processes. This is driving major investment in clean energy, more sustainable or new process routes, carbon capture, use of hydrogen as an energy carrier, or switching to circular bio-based or waste feeds. Siemens is paving the way with digital twin technologies that are key to addressing all these challenges.

We provide software, services and solutions to help accelerate three key phases of decarbonization. Our digital approach helps address these challenges:
Our solutions, your benefits
What do we do?Siemens digital twin tools and technologies and services are helping to drive sustainability in many areas:
Advanced technology: Dynamic optimization for demand side management
As renewable energy from variable sources such as wind or solar makes up an ever-larger share of energy, grid operators struggle to balance supply and demand. Siemens dynamic optimization technology can determine the best possible design for handling variability – for example, the optimal size of buffer tanks – or in operations, the most economic operating trajectory over a specified time horizon.
How we work with clean energy innovators
Siemens PSE works closely with many start-up companies active in clean energy and sustainable development, to help them bring new developments to market quickly.
We help them apply digital process design approaches in order to accelerate development by exploring the decision space rapidly, optimize process designs, and manage technology risk. Our goal is to help bring new technologies to market as rapidly as possible.
Here are some examples:
Creating a green hydrogen infrastructure for aircraft
Siemens worked with UK-based hydrogen solutions provider Protium on the Digital Twin project, grant-funded by the Connected Places Catapult and the UK Department for Transport, with the aim of digitalizing the development of green hydrogen infrastructure for aircraft.
Protium are implementing a Siemens digital twin to accelerate design and testing during development of rapid refuelling technology in support of the ultimate aim of Zero-Emissions Flight.
This novel approach to designing refuelling systems will increase confidence and understanding in the capabilities of emerging hydrogen technologyDr Jen Baxter, Director of Innovation and Policy at Protium
Hydrogen technologies are essential to support the 2050 net zero target for domestic flights. Green hydrogen produced using renewable electricity can replace conventional fossil fuels; however current technology is not able to deliver the rapid refuelling essential to make hydrogen commercially viable for the aviation sector.
Protium is at the forefront of the aircraft industry’s green transition and is dedicated to providing a holistic energy service for achieving zero emissions. The company designs, develops, finances and operates green hydrogen solutions across aviation, consumer-facing industrial applications and transport.
Protium and Siemens worked together to create new digital twin technology to accelerate the development of systems hydrogen refuelling of aircraft. The approach deploys a digital model of the refuelling system to explore the decision space and optimize system design, then simulate and optimize real-world performance, reducing the need for expensive prototyping.
The digital twin enables Protium rapidly to test innovative engineering solutions for aircraft refuelling and increase confidence in hydrogen technology, potentially contributing towards the UK government target of net zero carbon emissions by 2050.
Dr Jen Baxter, Director of Innovation and Policy at Protium said, “This novel approach to designing refuelling systems will increase confidence and understanding in the capabilities of emerging hydrogen technology, increase uptake across the UK and accelerate the transition to zero emission flight and tackle climate change”.
Bart de Groot, Business Manager Operational Excellence Solutions, Process Automation at Siemens, adds: “Siemens is working extensively with clean energy innovators to help bring new technologies to market as rapidly as possible. We are very excited to be working with Protium to reduce time-to-market in the challenging area of zero emission flight.”
Accelerating green hydrogen process and storage development
Everfuel, a key player in Power-to-X and green hydrogen technologies, chose Siemens’ gPROMS digital process design technology to implement high-fidelity digital twins.
The digital twins enable Everfuel to rapidly establish viability of design choices and quantify the risk associated with design and operating decisions. Engineers are able to systematically explore the complex process decision space and establish the economically optimal design based on validated high-fidelity process models.

Everfuel, headquartered in Herning, Denmark, is a key player in Power-to-X and green hydrogen, technologies that will play a vital role in the energy transition by providing large-scale energy storage capabilities and mitigating the fluctuation and unpredictability of renewable energy sources.
Everfuel is making green hydrogen for zero emission mobility commercially available across Europe, offering competitive all-inclusive solutions for hydrogen supply and fuelling. Green hydrogen is a 100% clean fuel made from renewable energy and key to electrification of the transportation sector in Europe, and hence to a sustainable future.
The company owns and operates green hydrogen infrastructure and partners with vehicle OEMs to connect the entire hydrogen value chain and seamlessly provide hydrogen fuel to enterprise customers under long-term contracts.
The successful design and operation of Power-to-X production plants and green hydrogen distribution facilities requires a digital design tool that can capture knowledge of inherently complex chemical and physical processes and support decision-making in all stages of the project delivery and plant optimization activities. In particular it needs to include process-critical components such as the electrochemical cell reactors.
Everfuel has adopted digital twin technology in the company’s flagship project, HySynergy, involving development of a large-scale electrolysis-based hydrogen production and storage facility in Denmark. Siemens’ gPROMS digital design is being used to explore the decision space, quantify risk, optimize the system design and scale up from the initial 20 MW plant to full-scale 300 MW production size. The digital twin enables Everfuel to accelerate development and maximize process economics by providing accurate information on which to base crucial decisions.
Uffe Borup, CTO at Everfuel, says "to secure Everfuel’s long-term objectives, we decided to collaborate with Siemens Process Systems Engineering and use gPROMS as our principal process simulation tool. We believe that the unmatched capabilities of gPROMS in process modelling, validation and optimization will help us secure the future of zero-emission mobility”.
Bart de Groot, Director of Sustainability at Siemens PSE, adds: “Siemens is working extensively with clean energy innovators to help them bring new technologies to market as rapidly as possible. We are very excited to be working with Everfuel to reduce time-to-market in this challenging area.”
Everfuel have also been using gPROMS to model a hydrogen distribution network, using the new gFLARE model library suite of advanced process safety tools for dynamic simulation of hydrogen safety scenarios.
