Global multi-sector industry coalition SEA-LNG on Friday (3 December) released a post recommending the shipping and oil industry to consistently refer carbon-neutral LNG as “renewable synthetic LNG”.
SEA-LNG exists to support the ongoing development of the LNG decarbonisation pathway and is dedicated to helping shipping thrive through the energy transition. The end goal of this pathway, to deliver net-zero greenhouse gas (GHG) emissions, requires the production of synthetic liquefied natural gas (LNG) from renewable electricity.
Renewable synthetic LNG, chemically identical to fossil LNG, but carbon-neutral, has made big advances in recent months – the ElbBlue, for example, became the first ever ocean-going vessel to be bunkered with synthetic LNG produced from renewable electricity, when it docked in Brunsbüttel, Germany, in late September. The drop-in versatility of renewable synthetic LNG and its biogenic relation, bioLNG, vindicates the continued pursuit of their commercialisation, as the order book for LNG powered ships expands.
The pathway faces challenges: loud calls for a winner takes all approach to fuel choice, when many of the fuels being championed are still at the starting gate; unthinking warnings of stranded assets, when investments made in LNG today can utilise its bio and synthetic cousins; misleading statements about methane slip, when developments by engine manufacturers are underway to eliminate it within the next few years; and confusion about the environmental performance, readiness, costs and availability of other alternative marine fuels.
The LNG pathway makes sense – from an emissions perspective and both commercially and operationally. However, anyone reading about the LNG pathway could easily be confused by the variety of terms used to describe the carbon-neutral forms of the fuel. In recent months, ‘renewable synthetic LNG’ has been referred to variously as carbon-based liquid methane, e-methane, eLNG, Synthetic Natural Gas, SNG, electro-methane, green methane, liquid green methane, liquefied synthetic methane (LSM), and hydrogen-based LNG.
Among SEA-LNG members, naming of the product is not always consistent.
SEA-LNG is committed to ensuring all our communications use the term renewable synthetic LNG. We’ve taken this step because we feel the term is clear and self-explanatory:
Renewable – It is produced from renewable electricity, for example solar and wind, and carbon from sustainable biomass or captured directly from the air around us.
Synthetic – It is manufactured through established technological processes and is not based on fossil-fuels nor derived directly from biomass.
LNG – It is chemically identical to the fuel used in shipping for more than 50 years. Implicit in this is that it can be burned in existing LNG-fuelled ships and utilise the existing network of supply infrastructure.
Though it is understandable that as our sector develops technologies for the LNG pathway, we may on occasion use different terms to describe the fuel, ultimately, we are talking about the same thing. We should aim to be consistent.
This month, SEA-LNG publishes a new animation explaining the LNG pathway, and the major role that renewable synthetic LNG has to play as the ultimate destination of that pathway.
SEA-LNG and its members would like the video to be an introduction and a crib for anyone interested in alternative marine fuels, whether individuals are in the industry, provide services or, like the vast majority of individuals and organisations, simply want to see action taken to address climate change now.

Singapore can help less developed countries in SouthEast Asia through ‘piloting and scaling fuels and technology as well as a leading hub for green finance’, said DNV Group President and CEO Remi Eriksen.
Octamar™ Ultra HF, Octamar™ Complete, and Octamar™ F35C were found to have improved the fuel economy while reducing exhaust gas and other emissions of marine engines in a series of trials, states report.
Disposal of evidence has resulted in Singapore not being able to provide full details to the United Nationals Panel of Experts which sought information regarding the case, says Ministry of Foreign Affairs.
‘We are proud to be amongst the first to show the successful steps taken by Singapore’s bunkering ecosystem to remain forward thinking and relevant,’ Choong Sheen Mao, Director of EMF, tells Manifold Times.
‘With the launch of a common data infrastructure, Kenoil aims to continue achieving an end to end visibility and transparency on the bunker data supply chain,’ states Kenoil Managing Director.
Digitalization can help shipping achieve its decarbonization goals but only if human factors are considered enough when introducing smarter maritime operations with ‘user-friendly’ technology.
