German luxury boatbuilder Lürssen Yachts has shared video footage of it successfully launching a zero-emissions megayacht longer than two olympic swimming pools, suspected to be commissioned by a Japanese billionaire. The exterior of hydrogen powered megayacht, codenamed Project Cosmos, is being designed by Apple designer Marc Newson.

Lürssen Yachts is a legacy boatbuilder with German roots dating as far back at 1860. After initially starting out building racing rowboats, Lürssen constructed the world’s first motorboat in 1886. It has gone bigger and better in the century and a half since that milestone, gaining a reputation in the maritime industry for consistently pushing the limits of engineering and innovation within its unique vessels.

Lürssen first committed to using fuel cells way back in 2009 and has been operating a methanol-hydrogen fuel cell power plant since 2012. That technology is present in its current megayacht build, Project Cosmos – which just made its technical launch onto the waters of Germany.

It’s a work in progress that still has a couple years to go, but you can already get a scope of its size and unique design from the images below.
