SEA\LNG and SGMF launched a study according to which GHG reductions of up to 21% are achievable now from LNG as a marine fuel, in comparison to the existent oil-based marine fuels over the entire life-cycle from Well-to-Wake (WtW). The study also confirms that emissions from sulphur oxides (SOx), nitrogen oxides (NOx) and particulate matter (PM), are close to zero when using LNG compared with current conventional oil-based marine fuels.
Mainly, the study called ‘The Life Cycle GHG Emission Study’ highlights the remarkable advantages of LNG as a marine fuel, according to SEA\LNG Chairman Peter Keller.
He supported that the transition from HFO to LNG does reduce GHG emissions.
It is clear that LNG is the most environmentally-friendly marine fuel that is readily available and safe, both today and in the foreseeable future.
… Peter Keller supports.
Moreover, WtW emissions reduction advantages for LNG-fuelled engines compared with HFO fuelled ships today are between 14% to 21% for 2-stroke slow speed engines and between 7% to 15% for 4-stroke medium speed engines.
Additionally, 72% of the marine fuel consumed today is by 2-stroke engines with a further 18% used by 4-stroke medium speed engines.
Chad Verret, Society for Gas as a Marine Fuel (SGMF) Board Chairman and study partner commented that LNG is safe to use, fully compliant and available.
LNG meets and surpasses all current and 2020 marine fuel compliance requirements for content and emissions, local and GHG.
Furthermore, the study suggests that the optimisation of the supply chain and engine technology developments will further enhance the benefits of LNG as a marine fuel.
Additionally, bioLNG and Synthetic LNG – both fully interchangeable with LNG derived from fossil feedstock – offer the potential for significant additional GHG emissions reductions. For example, a blend of 20% bioLNG as a drop-in fuel can reduce GHG emissions by a further 13% when compared to 100% fossil fuel LNG.
Dr Oliver Schuller, Team Lead Energy & Mobility at thinkstep stated
The main goal of this study was to provide an accurate report of the life-cycle GHG emissions from LNG as a marine fuel compared with conventional marine fuels.
Concluding, the study, commissioned by SEA\LNG and SGMF, was conducted by leading data and consultancy provider thinkstep according to ISO standards. The report, which has been reviewed by a panel of independent academic experts, is the definitive study into GHG emissions from current marine engines.
