SEA-LNG has conducted new analysis of
the green LNG bunkering market which shows that bio-LNG is available
today in almost seventy ports worldwide, including in Singapore,
Rotterdam and the US east-coast. The data on the expanded availability
of bio-LNG as a marine fuel is revealed in the coalition’s update to its
online Bunker Navigator tool, which provides information on the bunker
availability of fuels in the LNG pathway worldwide.
Bio-LNG used in the maritime industry is
produced from sustainable biomass feedstocks such as human or
agricultural waste, which means it does not compete with the production
of food, fibre or fodder, as defined by regulations such as the EU’s RED
II and the Renewable Fuel Standards in America. Annual production of
biomethane, from which bio-LNG is produced, is currently around 30m
tonnes or around 10 per cent of shipping’s total annual energy demand.
The current global fleet of 355
LNG-fuelled vessels, excluding LNG carriers, are all capable of using
bio-LNG as drop-in fuel without any modification. Bio-LNG can also be
transported, stored and bunkered in ports using the existing LNG
infrastructure, which provides a route to further expansion of its
availability in coming years. In general, the use of bio-LNG as a marine
fuel can reduce GHG emissions by up to 80% compared to marine diesel on
a full well-to-wake basis. Depending on the method of production,
bio-LNG can have net-zero or even net-negative GHG emissions on a
lifecycle basis, creating immediate opportunities for vessel operators
to cut GHG emissions and offering a sustainable route to decarbonisation
by 2050.
In October 2022, analysis by a team at
the Nanyang Technological University’s Maritime Energy and Sustainable
Development Centre of Excellence (MESD) which asked practical questions
about bio-LNG emissions, availability and cost showed a huge global
potential for the expansion of biomethane production of up to 20 times
current production levels by 2050. Accounting for demand for other
sectors, MESD forecast that bio-LNG as a marine fuel could be available
in sufficient quantity to fully decarbonise approximately 13% of the
global shipping fleet in 2050.
