Transport & Environment gathered innovative industry players and policy makers to discuss the future of zero-emission shipping. aviation
is a leading European manufacturer of ship engines that plans on delivering ammonia and methanol engines in the next few years. LMG Marin is a naval engineering company active in Norway, France, and Poland, that has already delivered several hydrogen ship projects. Another European company,, presented projects of supply of hydrogen, methanol, and ammonia to main ports in Portugal.
Aside from dedicated policies to boost e-fuels, more emphasis should be put to reduce fuel consumption, which could be achieved by mandating zero-emission berths and supporting wind sails technologies. Last but not least, the availability of supply and refueling infrastructure in ports are crucial for investment decisions in zero-emission ships. And in order to secure all this, legislative action is key.The aviation sector needs to be decarbonized at the very latest by 2050, but better before.
Using renewable electricity and direct air capture seems to be the most favourable and scalable technology available, with the added benefit that no infrastructure change is needed to drop the fuels in the engines. However, we still have to wait before we can fly with these fuels: production plants are yet to be built, and capacity is nowhere at the levels we need. Only then can we start talking about a viable solution to decarbonise aviation.
The event speakers were clear: the right political framework is needed to bring about zero-carbon aviation. While efficiency measures and demand management are first and necessary steps, technological change needs to follow suit. And this needs to be fostered rather than neglected by unambitious policies. European innovation can bring about change and pioneer zero-emission technologies, but policy needs to follow suit. Setting the right incentives will facilitate the scale-up of innovations.
