LNG as a fuel is both a proven and available commercial solution. LNG offers huge advantages, especially for ships in the light of ever-tightening emission regulations. Conventional oil-based fuels will remain the main fuel option for most vessels in the near future, and, at the same time, the commercial opportunities of LNG are interesting for many projects. While different technologies can be used to comply with air emission limits, LNG technology is the only option that can meet existing and upcoming requirements for the main types of emissions (SOx, NOx, PM, CO2). LNG can be competitive pricewise with distillate fuels and, unlike other solutions, in many cases does not require the installation of additional process technology.
