法国大西洋造船厂为地中海邮轮（MSC cruise）建造的世界上最大的液化天然气（LNG）动力邮轮宣布交付，这也是全球首艘搭载全新固体氧化物燃料电池（SOFC）技术的LNG动力邮轮。该邮轮长580.3米，可容纳2138名船员和6762名乘客，采用了包括船用LNG双燃料发动机在内的绿色动力系统。与传统船用燃料相比，液化天然气几乎消除了硫氧化物和细颗粒物等空气污染物的排放，能够大大减少氮氧化物的产生，同时还实现了25%的二氧化碳减排。此外，该船还配备了各种节能环保设备，以优化全船的能源利用。

The Cruise Division of MSC Group and French shipbuilding company Chantiers de l’Atlantique have announced the delivery of the world’s largest LNG-powered cruise ship and one of the first contemporary cruise ship to feature solid oxide fuel cell (SOFC). The ship measures 580.3 meters in length, is able to accommodate 6,762 passengers with a crew of 2,138 and incorporates the latest environmentally friendly characteristics, including a dual-fuel power plant for LNG. Compared to standard marine fuels, LNG nearly eliminates air pollutant emissions like sulphur oxides and fine particles, greatly reduces nitrogen oxides, and achieves a CO2 reduction of up to 25%. Additionally, it is the world’s first contemporary cruise ship to feature solid oxide fuel cell (SOFC) technology powered by liquefied natural gas. At the same time, the ship is also equipped with various equipment to optimize the energy utilization of the whole ship.

碳酸氢钠，俗称小苏打，是人们在烘焙时常用到的一种膨松剂。现在，它被用在了船舶的废气处理系统当中。总部位于伦敦的设备提供商SodaFlexx提出了一个新设想：用碳酸氢钠粉末来处理船舶废气。受到陆上废气处理技术的启发，他们将碳酸氢钠粉末直接注入废气流中以中和硫氧化合物。发生化学反应后，硫氧化物（SOx）将转化为稳定且无毒的硫酸钠晶体，然后被安全释放到大气中，或者通过SodaFlexx研发的颗粒捕捉器进行收集并在岸上回收。据悉，SodaFlexx的干式废气净化系统已经成功投入实际使用。

Sodium bicarbonate, a substance best known for its baking qualities, has emerged as a new scrubber solution. London-based SodaFlexx has created a concept to treat exhaust gas emissions from ships with sodium bicarbonate powder. The concept was adapted from proven land-based technology, where sodium bicarbonate powder is injected directly into the exhaust gas stream to neutralize sulphur compounds. A chemical reaction occurs converting SOx to a highly stable and non-toxic salt, sodium sulphate which is then either released safely into the atmosphere or can be captured by SodaFlexx’s bespoke cyclone particulate capture hybrid system and recycled ashore. The the SodaFlexx dry exhaust gas cleaning system has proved so successful by being thrown into an actual usage.
