Tokyu Hotels has created the first carbon-neutral hotel in the world to be powered by hydrogen, sourced from waste products.
Situated in the city of Kawasaki, Greater Tokyo – 50 minutes from central Tokyo by public transport – the Kawasaki King Skyfront Tokyo Rei Hotel is 30 per cent powered by hydrogen derived from waste plastics. The remaining 70 per cent of its energy comes from food waste.
Using H2Rex technology created by Toshiba, the hotel has a hydrogen fuel cell system, which transforms hydrogen into heat and electric power without producing carbon emissions. This technology is connected to the hotel via a pipeline, meaning there is a constant, high-volume supply of hydrogen, and the supply chain remains carbon-free.
Kawasaki King Skyfront Tokyo Rei Hotel recycles toothbrushes and hair combs left in its guestrooms, which become past of the plastic waste converted into hydrogen that powers the hotel.
In addition, the hotel grows its own produce inside the hotel through hydroponics (the process of growing plants without soil) and LED light source photosynthesis. For example, the hotel can grows pesticide-free lettuce inside its lobby, which it harvests once per month.
