🇫🇮 Harvia and Toyota develop hydrogen sauna
By using hydrogen in the sauna heater, the system produces only steam and warm air and no carbon dioxide, offering an attractive alternative to traditional heating methods. The aim is to explore new uses for hydrogen and promote carbon neutrality.
The concept aims to emulate the traditional smoke sauna, known for its gentle and pleasant heat. The hydrogen heater directs flames and warm air through the heater stones, heating them evenly on all sides. This process envelops the space with a gentle heat and produces a pleasant steam or steam when water is poured over the stones.
“The collaboration with Toyota allows us to expand our innovation in the sauna sector and demonstrates our commitment to environmental responsibility,” says Timo Harvia, Harvia’s Director of Innovation and Technology. “Toyota’s deep expertise in hydrogen processing and combustion gave us a safe and efficient way to pursue hydrogen as a clean energy source – something we might not have considered so soon without such a reliable partner. In doing so, we are not only exploring ways to minimise our environmental impact, but also creating a new kind of sauna experience that respects tradition while looking to the future.”
The hydrogen sauna will be presented at the World Sauna Forum from 4-5 June 2025 and as part of the Rally Finland from 31 July to 2 August 2025 in Jyväskylä.
