Hurtigruten to use dead fish for power

Hurtigruten are using leftover fish parts processed for food and mixed with other organic waste to generate biogas, which will then be liquefied and used in place of fossil fuels.

Hurtigruten is currently building three new hybrid-powered cruise ships in Norway, to be delivered in the next three years 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.

Shipping has come under increasing scrutiny as many vessels use heavy fuel oil, which is cheap but would be banned on land for its polluting qualities. The daily greenhouse gas emissions from the world’s largest cruise liners can be as great as those of a million cars on the road. Heavy fossil fuels used by ocean-going transport are an increasing problem as they are even more polluting than fuels for land-based vehicles, emitting sulphur and other contaminants. The fuels contribute to air pollution as well as to climate change. Converting vessels to use biogas will cut down on pollutants and reduce greenhouse gas emissions.

Daniel Skjeldam, Chief Executive of Hurtigruten, says: “Norway is a large shipping nation, but fishery and forestry are also large sectors. They create jobs and produce income, but they also produce a lot of waste products. The steady access to high volumes of organic waste gives the Nordic countries a unique position on the biogas market. We are pushing for more innovation, more investment. I believe we have just seen the beginning of what in a few years will be a huge sector.”
