The Re-Emergence of Wind Power : Read in Depth

Here in this article we are going to share about a report “Study on the Analysis of Market Potentials & Market Barriers for Wind Propulsion Technologies for Ships” that highlights all the potential of wind power in shipping industry.

The report’s principle author, Dagmar Nelissen, Senior Researcher and Consultant at CE Delft, talks to Maritime Holland about the findings.

Sustainable technologies are future proof technologies as we all know. While discussing about sustainable resources particularly in marine industry, the most important factor is need to look upon all the technologies that must have all the potentials to this sector to next century.

The most effective and efficient source of sustainable energy is wind energy and use of wind as energy in sailing industry is not new. Though the modern techniques can harness more energy as compared to traditional result. The image shown above is of ship under sail is a painted artifact dating back more than 7,000 years that was found in present-day Kuwait.

This study was prepared by CE Delft together with the Tyndall Centre, Fraunhofer ISI and Chalmers University, that is independent environmental research and consulty organisation.

It is supported by European Commission Directorate General for Climate Action who is aiming towards the fight against climate change happening at EU. and at an international level.

As per the Nelissen” There are lot of studies are  already published about slow steaming and about biofuels- There are lot of concerns over the negative impacts that can be caused by those fuels and also about their availabilty. “.

While the wind propulsion is hardly and barely used technique followed hard by many organisations on its development. Due to its abundant potential it was the reason to carry out the study. 

They have analysed 4 methods of Wind propulsion that is rotor, Wind Turbines, rigid sails, towing kites. There are 6 type of vessels two container, two tanker and two dry vessels.

Key results

“An important aspect of the study is that we used existing AIS route data over the period of one year for the sample vessels,” Nelissen notes.

“The data from actual studies significantly increases the level of trust in this study. It is an important step to gain access to financial investment. The situation is bit tricky, banks wants to check the results of tests to provide financial investments. While Developers need initial investment to provide financial investments to run their tests successfully. Our Proposal is to break the ice between developers and bank institutions by creating more trustworthy information so banks can release financial investments for developers.

The Study is covering a large area the results are so vast to summarize in this article. Precisely, rigid sails and rotors yield the best result, and the potential fuel savings can reach in double figures as compare to present using in large vessels.

On smaller vessels Towing Kites offer more savings while rotors exhibits least. While the absolute saving of rotor and rigid sales is directly proportional to its speed.

Impact on Market:

The technology have huge impact on market as well along with fuel savings and wind propulsion that are given below:

“Should some wind propulsion technologies for ships reach marketability in 2020, the maximum market potential for bulk carriers, tankers and container vessels is estimated to add up to around 3,700 – 10,700 installed systems until 2030. The wind propulsion sector would then be good for around 6,500 – 8,000 direct and around 8,500 – 10,000 indirect jobs,” the study states.

The environmental impact of this increase in the amount of wind propelled vessels is estimated to be a reduction of around 3.5 – 7.5 million tonnes CO2 in 2030.

Nelissen also added that since the industry is new it is hard to predict, these number of jobs has been caluclated by comparison with existing equipments of marine sector.

“But these results are only on bulkers, tankers and container ships. So theoretically the potential is higher, considering also the other types of vessels.”
