About this report

In the far reaches of eastern Finland, a small company is quietly reinventing one of aviation’s oldest ideas for the needs of the future. Kelluu Oy , based in Joensuu, has developed a hydrogen-powered autonomous airship that marries century-old lighter-than-air flight with cutting-edge sensors and artificial intelligence.

At first glance, Kelluu’s 12-meter blimps evoke the early days of aviation, but their mission is thoroughly modern: providing continuous, low-cost aerial surveillance and data for a range of civilian and defense applications.
