“The production of biomethanol will play an important role in developing methanol as a fuel since it will strongly reduce the CO2 impact. Liquified natural gas ( LNG ) could be the best alternative marine fuel to comply with the International Maritime Organization 's ( IMO ) 2020 sulphur cap , according to Dr Marc Martin , an independent consultant for Engie - Crigen . He said LNG was already compliant with incoming emissions regulations and readily available worldwide . He added there were no global availability concerns for the fuel , compared with other fuels such as liquefied petroleum gas ( LPG ) or methanol . He also noted LPG 's high volatility and concerns about its safety , adding that methanol is toxic and additionally hazardous because it burns with an invisible flame .
