Nordic operator Telia and the Swedish Post and Telecom Authority have launched a pilot which involves using hydrogen to help keep mobile sites operating in power outages.
In the event of a major power outage mobile sites can usually keep operating for another four hours, we’re told, however the hydrogen pilot is supposed to extend this to 110 days.
The trials took place at a Telia site outside Stockholm, Sweden, and combined hydrogen, fuel cells, solar cells and batteries to ‘dramatically’ lengthen the site’s operating time when running on backup power. As a rule mobile sites use only batteries and diesel generators as secondary power supplies, says the release.
The Roslagen project, as it’s called, is being financed by the Swedish Post and Telecom Authority and is planned to conclude in December 2025. Alongside Telia, Euromekanik, Powercell, Polarium and Soltech are also involved in putting it together.
