A groundbreaking pilot project by Telia and the Swedish Post & Telecom Authority has demonstrated the potential of hydrogen to revolutionize mobile site resilience during power outages.
Trials conducted at a Telia site near Stockholm revealed that integrating hydrogen, fuel cells, solar panels, and batteries could extend backup power capabilities from the current four hours to an unprecedented 110 days.
This marks the first instance such a combination of energy sources has been tested for a mobile site. Notably, the hydrogen used in the system can be produced on-site using renewable energy and stored locally for future use, further enhancing its sustainability and practicality.

Currently, mobile sites rely on batteries and diesel generators for backup power. The innovative pilot highlights how advanced energy systems could reduce reliance on the electricity grid while strengthening network availability and resilience, which is critical for today’s mobile users, businesses, and defense operations.
Staffan Åkesson, Head of Infrastructure at Telia Sweden, said, “The demand for connectivity, along with the current geopolitical situation, means mobile sites must be available even during longer power outages. We’re very pleased with the insights this project has already given us. They can be decisive in developing robust, sustainable solutions that help meet today’s challenges while future-proofing our infrastructure.”

The Roslagen project, funded by the Swedish Post & Telecom Authority, is set to run until December 2025, bringing together industry partners such as Telia, Euromekanik, Powercell, Polarium, and Soltech to test innovative hydrogen-based energy solutions.
As hydrogen gains prominence in the shift toward a net-zero society, the EU has outlined plans for renewable hydrogen to meet 10% of its energy needs by 2050. This aligns with Telia’s ambitious goal of achieving net-zero greenhouse gas (GHG) emissions across its entire value chain by 2040. The project underscores hydrogen’s growing importance in sustainable energy strategies, positioning it as a key enabler for reducing emissions while boosting energy resilience.
