Rheinmetall and partners look to facilitate armed forces producing their own synthetic fuel

Rheinmetall announced on 3 November 2025 that it is presenting a new strategic concept designed to ensure the operational readiness of armed forces by enabling them to produce their own fuel locally and independently of global fossil fuel supply chains.

Known as the Giga PtX project, the initiative, which has been developed in collaboration with partner companies, aims to establish a Europe-wide network of several hundred modular e-fuel production plants. Depending on the application profile, these plants will be capable of producing 5,000 to 7,000 tonnes of diesel, marine diesel or kerosene per facility per year. With this concept, Rheinmetall “is looking at strengthening the energy self-sufficiency and resilience of European armed forces in a sustainable manner while also contributing to the stability of critical energy infrastructure”, the company stated.

Rheinmetall is offering to act as general contractor and is responsible not only for system integration but also for the design, construction, maintenance and operation of the large-scale industrial facilities.

In order to be able to provide the plant technology immediately, a strong alliance of participating German major industrial players and leading clean-tech companies has been formed.

“We have exactly the partners we need,” Birgit Görtler, vice president of sales for hydrogen at Rheinmetall, was quoted as saying in a company press release. “We are prepared and can start immediately. We are literally ready to go in order to strengthen fuel resilience in Germany and Europe in the long term.”

Sunfire, a leading global manufacturer of industrial electrolysers, will be joining the consortium. The company’s pressuried alkaline electrolysers are intended to be an indispensable component of e-fuel production plants, ensuring the reliable supply of green hydrogen.

Sunfire’s portfolio also includes highly efficient solid oxide electrolyser cell (SOEC) technology. By utilising waste heat in the form of steam, the facility achieves a significantly higher conversion efficiency. This means that more hydrogen, and consequently more fuel, can be produced with the same amount of electricity. This technology is therefore ideal for use in e-fuel facilities.

In addition to green hydrogen, carbon dioxide is required to produce synthetic fuels. This is why Greenlyte, a new energy player based in North Rhine-Westphalia, is also joining the consortium. Using its modular technology to produce green raw materials, Greenlyte can capture carbon directly from the air, providing another key component for producing synthetic fuels at the Giga PtX facilities, alongside hydrogen. This feature enables the facilities to operate independently of existing infrastructure and with greater flexibility, thereby increasing location independence.

Alongside the new partners, Rheinmetall’s long-standing co-operation partner INERATEC from Karlsruhe also plays a central role in the consortium and is responsible for the heart of the facility: the reverse water gas shift (RWGS) and Fischer-Tropsch processes. These processes convert hydrogen and carbon dioxide into synthetic fuels. INERATEC recently demonstrated its leading expertise in the field of power-to-X technologies by commissioning Europe’s largest power-to-liquid facility in Frankfurt am Main. This facility produces up to 2,500 tonnes of sustainable fuel annually.

“War readiness requires a resilient energy infrastructure,” stated Rheinmetall CEO Armin Papperger. “Maintaining fossil fuel supply chains will be challenging for European countries in the event of a defence situation. With the Giga PtX facilities, Rheinmetall and its partners are sending a strong signal of industrial transformation, climate protection and security resilience in Europe.”

The first facilities can be realised at short notice as soon as the political and regulatory framework conditions have been established, Rheinmetall noted.
