According to a recent investigation, just one cruise ship can emit as much particulate matter as one million cars would in a single day.
But, as a sign of a greener future, the world’s first cruise ship to be powered by liquefied natural gas (LNG) departed from Tenerife on its maiden voyage in December 2018.
Unlike shipping fuels based on oil, LNG does not create sulphur oxide emissions and reduces nitrogen oxide emissions by up to 80 percent, particulate matter emissions by some 98 percent, and greenhouse gas emissions by up to 25 percent.
“Today’s maiden voyage takes Germany a major step closer to green shipping,” said Norbert Brackmann, Germany’s Federal Government Coordinator for the Maritime Industry. “LNG is a viable bridging technology for the time until we have zero-emissions vessels that protect our environment and the climate.”
The AIDAnova cruise ship was built in Germany using technology that was developed in Germany, in part with financial support from the Federal Ministry for Economic Affairs and Energy (BMWi) as part of its Maritime Research Program. Under the Federal Government’s new maritime program, which begins in 2019, funding will be channeled into efforts aimed at developing zero-emissions eFuels, which are synthetic fuels created by converting electricity generated from renewable sources into fuel.
