Investigation into so-called ‘inexperienced’ liquid pure fuel (LNG) ships uncovers important quantities of invisible methane being launched into the ambiance, exposing Europe’s soiled secret at sea.
Infrared pictures present unburned methane – a potent greenhouse fuel – being launched from supposedly ‘inexperienced’ LNG ships, a damning new investigation by Transport & Atmosphere (T&E) reveals. European politicians are enjoying with hearth of their assist for LNG, says T&E, with methane over 80 occasions extra local weather warming than carbon dioxide over a 20-year interval.
Delphine Gozillon, transport officer at T&E, stated: “Europe has a grimy secret at sea. In selling LNG ships, European policymakers are locking us right into a way forward for fossil fuel.The ships could also be painted inexperienced, however, beneath the floor, the reality is that the majority LNG ships available on the market at this time are extra damaging for the local weather than the fossil ships they’re supposed to exchange.”
Leaks and slips happen all through the pure fuel provide chain. Using fossil LNG as a maritime gasoline is especially problematic as a result of slips happen from ship engines. In accordance with knowledge from the Worldwide Maritime Organisation (IMO), relying on the engine, it has been estimated that between 0.2% to over 3% of fossil fuel slips from the combustion course of and is launched on to the ambiance.

For that reason, about 80% of LNG at this time is burned in an engine with worse whole greenhouse fuel emissions than conventional engines operating on soiled gasoline oil . Emission plumes that go up within the sky and stay there for a very long time are a sign of this.
T&E carried out the investigation on a transparent November day on the port of Rotterdam – Europe’s largest – utilizing a state-of-the-art infrared digicam, with a particular filter to detect hydrocarbon gases. As LNG is usually 90% methane, any unburnt gasoline that slips via the engine may also be primarily composed of the local weather warming fuel.
T&E was in a position to clearly observe important methane emissions from two ships. The primary of those was an LNG-powered container ship, the ‘Louvre’, owned by French transport firm CMA-CGM.
In accordance with a peer evaluation of the pictures carried out by TCHD Consulting, an optical fuel imaging consultancy, the pictures from the Louvre are proof that intense uncombusted hydrocarbon emissions have been being launched from the three exhaust vents into the ambiance above the ship and out of doors the body of the video.
In accordance with CMA CGM, its LNG ships allow a big discount in CO2 emissions per container and the corporate is investing closely in LNG. Its web site claims, “LNG is the perfect resolution at the moment out there to cut back the environmental impression of transport.” There isn’t a point out in any of its communication of methane, or how a lot methane sometimes slips from its vessels.

The second LNG-powered ship that T&E was in a position to observe was the ‘Eco-Delta’, a dredger used to clear transport lanes by pulling up sand from the ocean mattress. Once more, uncombusted and partially combusted emissions have been documented, with methane being launched from two scorching exhaust stacks on the entrance of the ship.
Shipowners commissioned extra gas-fuelled vessels in 2021 than the 4 earlier years mixed, with LNG ships promoted as a clear different to conventional fuels. The fossil fuel trade continues to foyer for LNG as a inexperienced transport resolution, pointing to low methane slippage based mostly on their very own knowledge in what T&E says is more and more trying like a ‘methane-gate’.
Final yr, the EU proposed carbon depth targets for marine fuels which might drive shipowners to maneuver away from residual gasoline oil, essentially the most broadly used transport gasoline at this time.
Nevertheless, T&E has warned that with out sustainability safeguards this can merely lock in LNG as the most affordable different. Latest T&E evaluation reveals that over two-thirds of latest ships may very well be powered with LNG from 2025. This could elevate the share of fossil LNG from an estimated 6% at this time to over one-fifth of all marine fuels in Europe by 2030 and lock-in fossil gasoline use into the 2040s.
Delphine Gozillon concluded: “We’re in a local weather disaster. We can not afford to place extra methane into the ambiance. Our investigation is only a small pattern, however it ought to act as a warning to policymakers. In selling LNG, it’s betting on the flawed horse. We needs to be specializing in genuinely inexperienced hydrogen-based options as an alternative.”
For now, T&E’s investigation has been restricted to 2 ships because of the complexity of finishing up such an investigation. LNG ships have been positioned and tracked by matching marine visitors knowledge and IHS knowledge that specifies the engine and gasoline kind of ships.
