e5 Lab and Almatech have partnered to promote the Zero Emission Speed Shuttle (ZESST) and enter the Japanese market.
ZESST is an innovative hydrogen-fuelled, electric-powered, zero-emission passenger shuttle vessel developed by Almatech. The partnership was signed by video conference on May 19, 2021 at the Swiss Embassy in Japan and EPFL Innovation Park.
Engineers at Almatech, who have been involved in space technology development and naval architecture for more than 12 years, spent around three years developing ZESST. The hydrogen-fuelled shuttle is equipped with high-efficiency hydrogen fuel cells and lithium-ion batteries.
Energy consumption per passenger/cruising range is about one-fifth of conventional diesel engine-powered vessels. The hull structure, which uses new-generation composites made with plant-based fibres, realises a further reduction in the vessel’s environmental impact.
ZESST combines speed, comfort, and safety, and uses no fossil fuels at all, emitting zero GHGs, SOx, NOx, and PMs, and generates minimal
wake and noise.
Japan, as a maritime nation, is expected to adopt it as the next-generation Mobility as a Service (MaaS) on the water.
The design is adaptable to vessels of various sizes (50-400 passengers) based on a modularised core system.
