Norwegian cruise ferries will be fueled by… dead fish
The operator of passenger-cargo ships sailing almost around the world, Hurtigruten, plans to use… dead fish to power some of its ships. This is to reduce greenhouse gas and pollution emissions, and ferries are a surprisingly large source of them.
Although it seems like a crazy idea, it really can make sense. Norway has a large fishing industry. Dumped dead fish remains, mixed with other organic waste, could be used to produce biogas.
– What others see as a problem, we see as a source ofodło and solution,” said Daniel Skjeldam, director of the company’s. – By introducing biogas as a fuel for shipsoin cruise ships, Hurtigruten will be the first cruise company thatora does not use to propel the shipoin fossil fuels – added.
Biogas generation is gently mowishing for a foul-smelling process, even without the involvement of leftover fish. The end product is a mixture of rogaseousoin, whichore are created when organic matter breaks down. The gases are primarily methane and carbon dioxide, but can roalso found small amounts of hydrogen sulfide, whichory is responsible for fromor rotten eggs. Such biogas can be purified and then liquefied to form liquid biogas.
But while this is a step in the right direction, biogas is not a favorite source ofoa source of energy for the ecologicalow. Carbon dioxide is still produced in the process, although in the non-porownanie smaller quantities than when using traditional fossil fuels. Additionally, biogas will never be a one-size-fits-all approach, as it is not suitable for every type of fuel system.
A company spokesman admitted that the first ship powered by biogas mohead would be ready as early as the end of next year. The company wants to have six hybrid vessels in its fleet by 2021oin powered by batteries, biogas and natural gas – the cleanest fossil fuel – and be completely carbon neutral by 2050.
Hurtigruten’s announcement comes in response to harsh criticism aimed at the cruise sectoroin cruise ships because of its impact on the climate and air quality. Recently, an American cruise ship captain P & O was fined €100,000 by French authorities for knowingly burning poor-quality fuel containing more sulfur than European limits. On the occasion of the case, calculations by a German environmental group appeared in the mediaoin Nabu, ktore moties that a large passenger ship fueled by heavy fuel oil emits almost as many fine particles per day as a million carsow.
A 125-year-old company thatora owns 17 shipsoin cruise ships, has banned roAlso the use of cups on its ferriesow, plateow or cutleryow disposable plastic products.
Hurtigruten’s environmental impact is particularolnie important because of where podrochew. They offer tours zaroBoth in Antarctica and the Arctic, the subroThey are chewing on exceptionally pristine waters, some of the cleaner in the world. – Being the world’s largest expedition line comes with responsibilities, Skjeldam pointed out.
