Norwegian Company Plans To Power Their Cruise Ships With Dead Fish

An anonymous reader quotes a report from The Guardian: Waste fish parts will be used to power ships in a new initiative to use green energy for polluting cruise liners. The leftovers of fish processed for food and mixed with other organic waste will be used to generate biogas, which will then be liquefied and used in place of fossil fuels by the expedition cruise line Hurtigruten. Hurtigruten operates a fleet of 17 ships, and by 2021 aims to have converted at least six of its vessels to use biogas, liquefied natural gas — a fossil fuel, but cleaner than many alternatives — and large battery packs, capable of storing energy produced from renewable sources. Biogas can be generated from most forms of organic waste by speeding up and harnessing the natural decomposition process to capture the methane produced. Organic waste is produced by all food industries but is frequently disposed of in landfill, where it contributes to greenhouse gas emissions as it decomposes. Hurtigruten is currently building three new hybrid-powered cruise ships in Norway, to be delivered in the next three years.
