Five years in the making, innovation-packed Breakthrough is the answer to her owners' inquiry: "What kind of green technology can you include?" Feadship's bold response was a multi-faceted, zero-diesel approach designed to cruise between harbours and to operate the yacht's hotel load and amenities with emission-free power from green hydrogen. One of the biggest hurdles was developing a reasonable way to store compressed liquid hydrogen below deck at -253°C aboard a luxury yacht, but the owner saw the value in investing in this technology necessary to make a transition away from fossil fuel to one of the most efficient and cleanest options.
