Landmark Well-to-Wake study represents definitive figures for GHG emissions and confirms LNG as major contributor in meeting IMO’s 2050 GHG targets for shipping

LONDON, 11th April 2019: The independent study report launched today has revealed that Greenhouse Gas (GHG) reductions of up to 21% are achievable now from LNG as a marine fuel, compared with current oil-based marine fuels over the entire life-cycle from Well-to-Wake (WtW).  It also confirms that emissions of other local pollutants, such as 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.

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.

Commenting on the report, SEA\LNG Chairman Peter Keller stated: “The Life Cycle GHG Emission Study is a long-awaited piece of the “LNG as a marine fuel“ puzzle.  It not only confirms what we already knew in terms of LNG’s immediate impact on air quality, human health and its cleanliness, but clearly highlights the genuine, substantiated GHG benefits of using today’s marine engines capable of burning natural gas.  Moving from current Heavy Fuel Oil (HFO) to LNG does reduce GHG emissions.  LNG does contribute to the International Maritime Organisation (IMO) GHG reduction targets. And 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.”

On an engine technology basis, the absolute WtW emissions reduction benefits 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. 72% of the marine fuel consumed today is by 2-stroke engines with a further 18% used by 4-stroke medium speed engines.

Study partner Chad Verret, Society for Gas as a Marine Fuel (SGMF) Board Chairman, added: “LNG is SAFE to use, fully compliant and readily available as a marine transport fuel.  Standards, Guidelines and Operational Protocols are all in place to ensure that the safe way is the only way when using gas as a marine fuel.  LNG meets and exceeds all current and 2020 marine fuel compliance requirements for content and emissions, local and GHG. With the world LNG Bunker Vessel fleet doubling in the next 18 months and those vessels being deployed at major bunkering hubs, LNG as a ship fuel is rapidly becoming readily available.”

Ongoing optimisation in 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.”

This is a comprehensive report using the latest primary data to assess all major types of marine engines and global sources of supply with quality data provided by Original Equipment Manufacturers including Caterpillar MaK, Caterpillar Solar Turbines, GE, MAN Energy Solutions, Rolls Royce (MTU), Wärtsilä, and Winterthur Gas & Diesel, as well as from ExxonMobil, Shell, and Total from the supply side. It is quality assured in assessing the supply and use of LNG as a marine fuel according to ISO standards. And objective having been peer-reviewed by leading academics from key institutions in France, Germany, Japan and the USA.”

Additional information about the Lifecycle GHG Emission Study on the Use of LNG as a Marine Fuel

The assessment of the GHG emissions (carbon intensity) of LNG has been carried out on a full life cycle basis. This includes the following life cycle phases: production & processing, pipeline transport, liquefaction, LNG carrier transportation (for imports), LNG terminal operations (for imports), bunkering (dispensing) and the final combustion in the engine. Several LNG pathways are analysed, including LNG from Algeria, Australia, Qatar, Indonesia, Malaysia, Nigeria, Norway, Trinidad & Tobago and the USA. In addition to the life cycle GHG emissions, local pollutants, like SOX, NOX, and PM are considered for the use phase of the fuels.

The study has been subjected to a critical review by a panel of independent experts according to ISO 14044, section 6.  The members of the critical review panel were:

  • Philippe Osset, Solinnen, Paris (France) – CEO, member of the ISO 14040/14044 working group – Chair of Review Panel
  • Prof Atsushi Inaba, Kogakuin University (Japan) – Department of Environmental and Energy Chemistry – reviewer
  • Prof Dr Friedrich Wirz, Technical University of Hamburg (Germany)- Head of Working Group Marine Engineering – reviewer
  • Dr Michael Wang, Argonne National Laboratory (USA), Group Manager Systems’ Assessment Group, Energy System Division – reviewer

The study uses the latest primary data to assess all major types of marine engines and global sources of supply, including:

  • 2-stroke slow speed (most common for high-powered ocean-going ships which consume 72% of marine fuel)
  • 4-stroke medium speed (18% of fuel usage, primarily in ferries and cruise ships)
  • 4-stroke high speed (5% of fuel usage)
  • Others (5%)
