Harvia and Toyota team up for hydrogen-powered sauna

HELSINKI: Harvia Plc and Toyota Motor Corp have teamed up to produce a concept model for what is believed to be the world's first hydrogen-powered sauna.

Harvia is one of the leading companies operating in the sauna and spa market globally.

In a statement, Toyota said the collaboration represents a step toward a more sustainable future for saunas by combining Harvia's sauna expertise with Toyota's hydrogen combustion technology.

The two companies will introduce the hydrogen sauna concept at two upcoming events in Jyväskylä, Finland.

These demonstrations aim to explore new uses for hydrogen and contribute to carbon neutrality.

The hydrogen sauna concept will be presented at the "World Sauna Forum" (June 4 - 5, 2025) and during part of "Rally Finland" (July 31 - August 2, 2025) in Jyväskylä.

By applying hydrogen to sauna heaters, the system generates only steam and warm air, emitting no CO2 during use.

This offers an attractive alternative to conventional heating methods.

The concept model aims to capture the essence of traditional smoke sauna, known for their gentle and soothing heat.

The hydrogen combustion heater channels flames and warm air through sauna stones, heating them evenly from all sides.

This process envelops the space in a soft warmth and produces the pleasant steam, or löyly, when water is poured on the stones.

"This collaboration with Toyota allows us to push the boundaries of sauna innovation and demonstrate our dedication to environmental responsibility," says Harvia head of innovation and technology Timo Harvia.

"Toyota's deep expertise in hydrogen handling and combustion gave us a safe and efficient way to pursue hydrogen as a clean energy source," he added.

"Jyväskylä is a key location for Toyota and Toyota Gazoo Racing World Rally Team, with whom we have worked together for many years," says Toyota president of hydrogen factory Mitsumasa Yamagata.

Toyota views hydrogen as an important fuel in pursuit of carbon neutrality and has been promoting various initiatives in the areas of "Create, Transport, Store, and Use" hydrogen in collaborating with partners across various industries.
