2nd November 2021: Windship Technology can today reveal that its Zero Emissions solution for shipping has been independently assessed by classification society DNV.

By using data provided by Windship Technology – a British innovation company – DNV has performed an independent computer-based analysis of the concept’s emissions abatement potential.

Speaking about this significant development, Simon Rogers, Technical Director of Windship Technology stated: “Today everything changes. The world now has a True Zero Emission solution for the shipping industry with technologies that are available today and a commercial case rooted in economic sustainability. It’s a significant inflection point for the shipping industry. From a technical standpoint, Windship Technology is now verified.”

DNV’s analysis of Windship Technology’s True Zero Emission solution for shipping was extensive and thorough, based on a holistic approach factoring sound scientific practices and the data provided by Windship Technology. 

Using the COSSMOS analysis modelling suite for the drivetrain and based on the information provided, DNV assessed that Windship Technology’s solution captures 100% of the CO2 generated whilst providing 49% fuel savings. 

Per Marius Berrefjord, Senior Vice President and Business Development Leader at DNV Maritime, said: “After extensive testing and modelling, the results from our analysis of Windship Technology’s innovative solution confirm that this design can provide a zero-emission system with the capability to save 49% of the expected fuel consumption of an Aframax Tanker.”

Brian Sweeney of Calix Limited, said “Calix’s LEILAC Technology can produce very highly reactive lime with zero emissions. In our RECAST invention, this lime is used on a ship to absorb CO2, clean the exhaust gases and supplement power production. Given this independent verification of our modelling we are keen to engage in the planned demonstration programme. We look forward to working with Windship to deliver this shipping solution globally.”

Emeritus Professor Philip Wilson, Professor of Ship Dynamics at the Ship Science Department at the University of Southampton, said: “An incredible conclusion to a deep study by a leading registrar and classification society of ships.  The system that delivers a true zero emission ship demonstrated by using real data is a remarkable and a humbling output to all the world ship operators, ship builders and ship designers. This has to be given a fanfare from the highest mountains and a wake-up call to the industry as a whole.”

In due course, Windship Technology will issue further information on its cost-efficiencies in relation to future fuels showing comparative costs. Windship will demonstrate zero CO2 emissions, NOx, SOx and particulate matters and VOC (volatile organic compounds) with a clean exhaust emitting non-toxic nitrogen, oxygen and water. This will further bolster the economic case and provide solutions for commercial fleet operators, shipbuilders and charterers. 

The baseline for DNV’s evaluation was annual live AIS data and full operational profiles for 20 Aframax vessels in operation on US-Europe routes, 12 times each per annum. Windship Technology’s rig combines wind power, solar electricity, modular diesel electric drive with Calix RECAST carbon capture and waste-heat recovery. DNV has shown this to reduce total operational fuel consumption by 49% (including port operations in laden and ballast condition) whilst emitting zero CO2. 

Furthermore, with EEXI legislation coming in 2023, Windship Technology’s solution has the potential for further significant fuel savings with zero CO2 emissions if the average operational speeds come down from 12 knots
