[ Lng ] restarted after it was suspended in 2021 . Qatar is developing into an important supplier to China , with Sinopec and CNCP signing long-term contracts . The country is developing phase 2 of its North Field South expansion with the help of Shell and Exxon Mobil . Elsewhere in the Middle East , the Leviathan field is being expanded to serve European markets ; this includes an FLNG terminal off Israel . In eastern Asia , two important projects are taking shape . The Philippines , which is already developing six projects , has approved a smallscale terminal , Samat LNG , in Bataan province . In Papua New Guinea , Total Energies is developing Papua LNG , with four trains to be built in an existing plant .

Decarbonisation Efforts to reduce the carbon emissions of LNG operations take many forms . Higher emission standards , carbon capture and bio-LNG are among the tools available . Another is to replace gas by hydrogen in the combustion process , as GE Gas Power and Shell
Materials
LNG cryogenic applications , including storage tanks , and liquefaction and regasification facilities , all use carbon or stainless-steel grades that include nickel , especially austenitics . But nickel is expensive and in great demand , so it is desirable to replace it whenever possible . Therefore , Posco developed high-manganese steel to improve durability , strength and cryogenic toughness . It can be applied in cryogenic LNG and fuel tanks . The new alloy has so far been applied in Posco ’ s land LNG-storage tanks Gwangyang , South Korea ; in Exxon Mobil storage tanks ; in a tank on the LNG bunker ship Ilshin Green ; and in LNG fuel tanks on a series of very large crude oil carriers ( VLCCs ) made by DSME .
are attempting to do . Also , IHI is researching technology to convert LNG receiving and storage terminals into ammonia-based facilities .
LNG-fuelled ships Decarbonisation of ship fuel is brought about by replacing diesel with LNG . Wärtsilä ’ s engines allow the use of dual-fuel technology , usually diesel alternating with LNG or some other gas or biofuel . A case in point is the new Wärtsilä 25 medium-speed 4-stroke engine , which is more efficient
and compact and is highly flexible owing to its different valve timing options . It is also designed to run on ammonia .
Conclusion Even before the Russian-Ukrainian war , LNG has proved to be a vital transitional fuel , while transportability has created a global demand and introduced flexibility into the natural gas market . Despite the current lull in gas prices , future competition for LNG is likely to be fierce .
