Harvia and Toyota have joined forces to create a groundbreaking concept model of the world's first hydrogen-powered sauna, merging Harvia's sauna expertise with Toyota's hydrogen combustion technology. This innovative collaboration aims to introduce a sustainable and environmentally friendly approach to sauna heating by utilizing hydrogen to produce steam and warm air without emitting CO2 during operation. The concept model, to be showcased at the upcoming World Sauna Forum and Rally Finland events in Jyväskylä, Finland, embodies a blend of tradition and modernity, offering a unique sauna experience that respects heritage while embracing innovative technology. The hydrogen sauna, characterized by its gentle and enveloping warmth similar to traditional smoke saunas, utilizes a hydrogen combustion heater to heat sauna stones evenly from all sides, creating a soothing atmosphere enhanced by the release of pleasant steam ('löyly') when water is poured on the stones. This approach not only enhances the sauna experience but also underscores a commitment to sustainability and carbon neutrality. Timo Harvia, Head of Innovation and Technology at Harvia, expressed enthusiasm for the partnership with Toyota, highlighting the opportunity to explore new frontiers in sauna innovation and environmental stewardship. This collaboration signifies a proactive step towards minimizing environmental impact while redefining the sauna experience for the future. Mitsumasa Yamagata, President of Hydrogen Factory at Toyota, emphasized the significance of this project in promoting hydrogen utilization and fostering trust within the local community. Harvia, a key player in the global sauna and spa market, and Toyota, a pioneer in promoting hydrogen for carbon neutrality, are driving towards a cleaner, more sustainable future through this pioneering initiative. By integrating hydrogen into sauna heating systems, the collaboration not only enhances the sauna experience but also sets a precedent for innovative applications of hydrogen technology across industries, underscoring a shared commitment to environmental welfare and technological advancement.
