Decade of Wind Propulsion


International Windship Association and it’s 130+ members have declared the period 2021-2030 as the “Decade of Wind Propulsion”, a decade of delivering wind propulsion installations, optimising the technology solutions and helping to facilitate a quicker, deeper and ultimately cheaper transition to a fully decarbonised fleet. Press Release – Driving the Decade of Wind Propulsion 

Open Letter – A Level Playing Field Needed in Shipping Decarbonisation
Over 90 maritime companies, shipowners, designers and technology providers all involved with wind propulsion have come together to release this open letter, calling for maritime industry decision-makers and the shipping community to fully assess and utilise all available power solutions that deliver the necessary deep/swift cuts in carbon emissions over the next decade commensurate with responding to the climate emergency. To that end, readily available and proven direct wind solutions must be integrated at the heart of decarbonisation deliberations, which is currently not the case.

16 August – Farewell to Wind Propulsion Visionary, Mr. Aloys Wobben, founder of Enercon and father of the E-ship 1
Very sad to hear about the passing of Mr. Aloys Wobben, 69, after a long illness. His vision for a new build wind-hybrid cargo vessel with four Enercon-designed Flettner rotors was launched in 2010 and has been in operation since saving c.20% of fuel. His vision was encapsulated in the choice of name, E-ship 1, the first of a fleet of vessels that unfortunately wasn’t replicated at the time, but which helped inspire a new industry and all of us at IWSA. We hope that we will be able to deliver on a wind powered fleet during this decade of wind propulsion, and that will form a small part of Mr Wobben’s legacy. Our condolences to the Wobben family and to the Enercon team and E-ship 1 crew.

08 August: Short Youtube film: Is Wind Power the Future of Freight Shipping? from Just Have a Think

The film covers some of the key aspects of wind propulsion and three of the seven technology groups that are being developed today. As the film makers state: “Wind power for boats has mostly been confined to niche sports and leisure activities these days, but new technologies are bringing a fresh perspective to the role that the wind can play in reducing costs and greenhouse gas emissions in the global freight shipping industry. That industry currently accounts for nearly 3% of all GHG emissions, so freight operators are on a quest to reach net zero by 2050. Here’s three of the most promising wind power options that could help them get there.”

04 August – Article: Wind assisted ship propulsion has returned in ship design – Learn a little more about the E-ship 1, in this interview with the Ship’s master Antje-Friederike Herbst, one of very few female captains in the German merchant fleet. 

Since commissioning, E-Ship 1 has travelled over 500,000 nm with the rotors reducing annual fuel consumption by 20% (annual mean) compared to similar-size conventionally powered vessels (920t of MGO at 13kn). This prototype vessel wasn’t replicated for a number of reasons (none of which were related to performance), and won the IWSA 2016 award Wind Propulsion in Commercial Shipping – Innovation Award. E-ship 1 continues to ply the waves, but now she is joined by nine other rotor installed vessels from tankers to bulkers, ferries to general cargo and many more in the pipeline.  Read more…

03 August – Webinar scheduled for 08 September, “Going beyond Compliance: Harnessing the wind to meet IMO’s EEXI regulations and increasing demand for higher ESG standards”. IWSA SG will be on the panel along with Tuomas Riski, Norsepower CEO,  Kris Fumberger, Sustainability Manager RightShip, Aude Leblanc Technology Leader, sustainable shipping Bureau Veritas & moderated by Alisdair Pettigrew, Director of BLUE Communications

The panel will explore potential market consolidation during the transition to net zero and the commercial and regulatory drivers impacting decision making for developing resilient fleets. With this combination of factors, shipping faces an unprecedented challenge to decarbonise that will require the sector to invest in new initiatives driven by push and pull effects. What are the near-term challenges for ship owners and operators in meeting imminent EEXI and CII requirements and how can these be overcome? How can ship owner and charterers collaborate better to reach favourable commercial agreements whilst working towards environmental goals? How can the industry future-proof against ESG demands and higher fuel costs?

05 May – Leaders Magazine Interview  – IWSA SG Gavin Allwright was recently interviewed by Dr Magdy Sadek, editor of for the Saudi Arabian magazine ‘Leaders’, and was was asked to reflect on the place that wind propulsion can have for stakeholders in the region and specifically in relation to the KSA Vision 2030. There is great potential benefit for Saudi fleet operators and owners, even with a fleet that is relatively new and best in class when it comes to efficiency and regulatory compliance. The deployment of wind propulsion systems can go even further and make those vessels leading statements of a ‘beyond compliance’ approach, locking in lower fuel costs and emissions and helping to take a leading role in the decarbonisation of shipping. There is nothing more visual as a statement of the intent to decarbonise a vessel or a fleet than wind-assist installations and as a zero-emissions energy source with modern wind propulsion technologies increasingly available to harness that, wind propulsion will certainly be a leading technology in the decarbonisation toolbox going forward.

24 March – Open Letter Release – A Level Playing Field Needed in Shipping Decarbonisation 

Over 90 maritime corporations, shipowners, designers and technology providers all involved with wind propulsion have come together to release this open letter, calling for all maritime industry decision-makers and the entire shipping community to fully assess and utilise all available power solutions that deliver the necessary deep, swift cuts in carbon emissions over the next decade commensurate with responding to the climate emergency. To that end, readily available and proven wind propulsion solutions must be integrated at the very heart of decarbonisation deliberations, which is currently not the case.

This is a critical time for all political, financial and corporate leaders to take decarbonisation seriously and the letter calls for establishing a multi-stakeholder International Working Group to evaluate and quantify wind propulsion’s potential, to launch a comprehensive Strategic Review of shipping industry decarbonisation efforts in the context of the climate emergency. It asks to ensure a ‘level playing field’ is created and maintained for all power systems and to do more and go beyond the current narrow fuel-centric approach.

27 December – Decarbonising short-sea shipping: Tyndall Centre proposal

The Tyndall Centre are looking for stakeholders interested in engaging with their new project: tackling the committed CO2 emissions from short-sea shipping.  

The Tyndall Centre’s recent research on the CO2 locked into the existing EU fleet demonstrates the importance of targeting carbon mitigation at existing ships (Bullock et al. 2020). This new project aims to tackle this by articulating the suite of technologies, propulsion systems and operational practices that offer the most rapid, far-reaching, economic and sustainable route to decarbonisation for the existing short-sea shipping fleet. Critical to the success of this project will be stakeholder engagement and support. The Tyndall Centre are therefore seeking stakeholder partners who may be interested in providing any level of participation, such as participation in workshops, expertise exchange or data provision. In return, stakeholders would have participation and influence in the discussion of policy recommendations and direct access to researchers focusing on the decarbonisation agenda within the Tyndall Centre.

If you would like to engage with the research program or would like additional information, please contact: James Mason

11 November – International Chamber of Shipping report ‘Catalysing the Fourth Propulsion Revolution’.

Very pleased to see the front cover of the latest International Chamber of Shipping report ‘Catalysing the Fourth Propulsion Revolution’ featuring the Wallenius Marine Oceanbird project.
We agree with the report conclusion that there is a lot of decarbonisation work to do over the coming decade and beyond and the cost will be substantial to bring alternative fuels on line.

It is excellent to see the focus on ‘a propulsion revolution’ and not just a ‘fuel revolution. Direct wind-assist and primary wind propulsion are included in this overview (page 18), and of course we agree that wind systems are an integral part of the decarbonisation pathway forward and systems will be optimised in time and will give increased amounts of energy as those are developed further. (IWSA figures are retrofits can deliver 5-20% today, with potential for 30% as those are optimised. For primary wind new builds those numbers are far higher, especially when combined with weather routing, speed or power modifications etc.)

The report is released as part of ICS push for the proposed $5 billion innovation fund at IMO, and the R&D funding for wind propulsion systems that can be deployed quickly, without additional infrastructure and with energy available worldwide, offer the lowest of the low hanging fruit when it comes to shipping decarbonisation efforts.

STEERER (Structuring Towards Zero Emission Waterborne Transport)
IWSA is very pleased to see that our engagement and the engagement of IWSA members and supporters has ensured that the STEERER project has been able to evaluate wind propulsion and that wind-assist and primary wind propulsion are included at the heart of the Strategic Research and Innovation Agenda (SRIA) for the co-programmed Partnership zero-emission waterborne transport which has been developed by the Waterborne TP and is nearing finalisation. This Agenda lays down the research and innovation strategy, the implementation pathways for different segments of the waterborne transport sector, and the activities foreseen to be able to achieve the Partnerships objectives. The draft SRIA was published for an open consultation in July/August and invited all interested stakeholders to contribute with comments. This feedback (the report from the open public consultation) and the revised draft SRIA, which incorporates comments from this consultation, are now available online.

Announcement: IWSA is delighted to announce that we are now members of the International Renewable Energy Agency (IRENA) Coalition for Action – we look forward to contributing our unique perspective on the drive to decarbonise through renewable energy development and the place that direct energy use has in the transformation of the shipping transport sector.

Coalition Vision and Mission StatementThe world’s transition to renewable energy sources is a defining trend of our time. It requires fundamental transformation in the supply, distribution, consumption, and management of energy. While substantial growth in renewable energy deployment is already taking place, the global energy transition is of such scale and pace that a significant level of international collaboration is required to succeed. The vision of the IRENA Coalition for Action is for its members to work together to advance renewable energy in order to drive the global energy transition in line with the Sustainable Development Goal on energy.

The Coalition forms a key international network to discuss and determine action on renewable energy industry trends, share knowledge, and exchange best practices for the global energy transformation. The mission of the IRENA Coalition for Action is to convene a global dialogue amongst nongovernmental and governmental stakeholders to develop actions to drive the energy transition forward by increasing the share of renewables in the global energy mix.

The Coalition brings together private sector entities, industry associations, the investment community, intergovernmental organisations, civil society, and research institutes to enrich and share perspectives on renewable energy technologies, implementation strategies and evolving market dynamics.

28 September – Bound4Blue featured in Forbes Magazine: Wingsail Technology Uses Wind To Reduce Ships’ Emissions By 30% 

Carbon Levy Developments – The debate on carbon levies/taxes for shipping has moved on quite considerably this month. Both proposals explicitly encourage the return of the proceeds into the industry to further encourage decarbonisation technology R&D and deployment.


25 September – Trafigura Carbon Levy Proposal – Trafigura, one of the world’s largest ship charterers, proposes that the IMO introduce a carbon levy of between $250-$300 per tonne of CO2 equivalent on shipping fuels to boost decarbonisation efforts in the industry. This is the equivalent of $750-$900 per tonne of fuel (effectively quadrupling today’s price). They also propose a similar ringfencing of proceeds that would raise billions for R&D into alternative propulsion and assist small island developing states and other developing countries mitigate the impacts of climate change.
Download Proposal


15 September – EU Emissions Trading Scheme (ETS)  – Inclusion of Shipping
The EU parliament has voted to include emissions from ships over 5,000 gross tonnes in the emissions trading system (EU ETS) by 1 January 2022. Parliament also wants firms to cut ships’ annual average CO2 emissions by more than 40pc by 2030. This will include the ring fencing of 50% of the proceeds to return to the industry in the form of decarbonisation innovation funding.

Interesting Fathom World Arronax Interviews with Jutta Paulus, the MEP driving Parliamentary proposal to have shipping join the EU ETS and increased efficiency mandates along with Adam Berman, EU Policy Head at the International Emissions Trading Association. These timely interviews were done just ahead of EU deliberations on this and with Parliament having now passed the proposal all eyes will be on how IMO reacts to that over the next couple of months as it get’s back to work on decarbonisation. There is always push back against any attempts at regional regulation in shipping, viewed by many in shipping as a global industry and therefore should only be regulated by the global body, the IMO.  There is also clear acknowledgement that the current price of carbon is insufficient to drive decarbonisation, thus the EU has added efficiency mandate into the proposed measures too.

11 September – International Energy Agency (IEA) released their Energy Technology Perspectives 2020 report that estimates that zero-emission shipping will cost $6trn (out of total $21trn transport conversion). Concludes that biofuel blends and energy efficiency measures (including already available wind-assist technology) will be the most important components in the transition for at least the next decade and probably up to 2040.

The report does however again miss the huge potential for optimised wind-assist systems and new build primary wind vessels entering the fleet in the next couple of years. The impact of extensive penetration of wind propulsion systems across the fleet could reduce overall fuel requirements from 20-30% by 2050, this in turn will be enhanced by improved weather routing, speed adjustments and other operational measures etc. Wind will also have a facilitating role, where significantly reduced alternative fuel requirements will mean less onboard storage required, potentially less power required and thus lower cost installations for new fuel systems. Extending range for vessels using wind will also enable ship operators to bunker where these new and likely costly alternative fuel supplies are more abundant, thus potentially reducing costs further.

09 September – Webinar: Renewable Transportation: Shipping and Aviation
Hosted by World Wind Energy Association In collaboration with the International Windship Association and the International Association for Sustainable Aviation

Time: Wed, 9 Sep 2020, 12:00-14:30 (CEST).

While the power sector in many countries is progressing well towards a full renewable energy supply and land based transportation is taking major steps away from fossil, fuels, two important areas have hardly been tackled: Aviation and Shipping. In order to achieve the goal of a climate neutral world and to shift human economic activities completely towards renewable energy, it is imperative that these two sectors be converted too. Although today almost all vessels and planes are fuelled with fossil fuel, very promising concepts are available with the potential of completely switching away from such fuels. This webinar will present the state of the art in aviation and shipping and will discuss actual and potential solutions. A special focus will be on how wind and other renewable sources can support these two difficult-to-abate transportation sectors in managing this transformation.
Presenters include:

14 February: IMO MEPC 75 Submission – Wind Propulsion Information Paper
Very pleased to announce that the wind propulsion info paper submitted by the Comoros flag has been accepted as MEPC75 Inf.26 and is now available to all delegates and is also publicly available through IMO docs and a pdf copy can be downloaded here too. MEPC 75-INF.26 – Wind propulsion solutions (Comoros) (1)  

The Executive Summary reads: “The decarbonization of shipping is the defining issue of the coming decade; however, currently, one of the leading decarbonization technologies, direct wind propulsion, is receiving only very limited consideration in this critical debate over the future of shipping. Direct thrust from wind propulsion technologies offers a technically and commercially viable near-term solution that can already save 5% to 20% of fuel and associated emissions as wind assistance, with the potential for much higher benefits as the technology develops or is deployed on optimized newbuild ships. Wind solutions are cost-effective, do not depend on alterations to port infrastructure and ensure shipowners have improved operational autonomy in mitigating the risks and uncertainties of being commercially dependent on the unknown cost and availability of alternative fuels. Therefore, the adoption of wind solutions will greatly assist the global fleet in reducing net emissions in the short-term, reducing the carbon intensity of the whole fleet, and better enable to meet IMO GHG reduction targets.”

NOTE: Further more technical submissions will be made at subsequent IMO MEPC sessions so that remaining barriers and challenges can be tackled effectively and a level-playing field put in place that fully values the substantial propulsion contribution delivered by wind propulsion solutions.

12 February: Safety4Sea London Forum: IWSA Secretary general presentation on wind propulsion progress over the last 12 months and future development. The 2nd SAFETY4SEA London Forum is scheduled as a full day event (09:00 to 17:00) on Wednesday 12th of February 2020 at the Hellenic Centre, London UK.
