Wind propulsion moves to the mainstream as industry momentum builds

The strong presence of wind propulsion technologies and expertise at Posidonia, held on 1-5 June, underscores the growing interest among Greek and international shipowners in practical decarbonisation solutions that can reduce fuel consumption, improve efficiency and support compliance with evolving environmental regulations.

Reflecting the rapid commercial growth of wind propulsion, twenty members of the International Windship Association (IWSA) will be exhibiting or hosting wind propulsion-related events at the exhibition, making the largest-ever showcase of modern wind propulsion technologies at the world-renowned maritime trade fair.

So far this year, we have witnessed new project announcements, order confirmations, and installation celebrations almost every week. This is a technology sector and renewable energy solution that is clearly moving into a phase of large-scale commercial adoption.

…Gavin Allwright, Secretary General, IWSA, commented.

According to analysis conducted by the Tyndall Centre for Climate Change Research in collaboration with Seas At Risk for the International Windship Association, the vessels required to meet the shipping industry’s 2030 climate targets are already operating at sea and they can be powered by wind. By retrofitting ships with modern sail and wind-assist technologies, operators can immediately reduce fuel consumption and emissions, while scalable alternative fuels remain years, if not decades, from widespread availability.

Furthermore, IWSA is increasingly seeing fleet-wide investment strategies emerge, with shipowners placing multi-vessel orders rather than limiting deployments to single ships. Currently, there are more than one hundred vessels that either have wind propulsion systems installed or are classed as being ‘wind-ready,’ representing a combined total exceeding six million DWT and marking a nearly three-fold increase since the previous Posidonia exhibition in 2024.

Allwright continues by highlighting that Posidonia provides the ideal global platform for the maritime industry to experience first-hand the latest developments in wind propulsion technology, especially given the strategic importance of the Greek shipping market and the international audience the exhibition attracts.

We are delighted to see so many IWSA members participating across the exhibition floor, conference programme, and member-hosted events. This edition of Posidonia will be the biggest yet when it comes to wind-powered shipping technologies — and the pace of growth suggests the sector will certainly be even larger by the time the industry returns to Athens in 2028.

…Allwright highlighted.

To help visitors navigate the extensive wind propulsion presence across the exhibition halls and associated events programme, the IWSA has also produced an ‘unofficial’ Wind Propulsion Route for the exhibition, to discover all of the wind-assist technology, equipment suppliers and service providers being showcased.
