This is BB GREEN

BB Green is an EU funded development project that resulted in the realisation of the BB Green Air Supported Vessel "AiriEl" that runs on an air cushion and thus use 40 % less power than a traditional high-speed catamaran. BB stands for Battery Boat and the batteries are new lightweight LTO batteries.
BB Green brings 80 passengers into the city at 28 knots while making limited wake wash. It is the ideal commuter that outperforms the car in big cities with traffic congestion and hazardous emissions.
Being emission free will be an absolute must in most cities in the near future. What is even more interesting is that this high-speed electric passenger ferry operates with an energy cost that is 50 – 80 % less than a traditional diesel driven high-speed catamaran.

This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement n°738295

EU Funded

In 2012, the project BB Green started with a 3.2 M€ funding from the FP7 EU Programme. The challenge was to develop and build a battery driven ASV (Air Supported Vessel). It was designed by the Norwegian Surface Effect Ships / Effect Ships International and built by Latitude Yachts in Riga. The electric driveline was designed by Echandia Marine in Sweden and the LTO batteries were supplied by Leclanché. The Carbon fibre technology came from DIAB. In May 2016, the vessel was ready for launching

Meanwhile, EU had decided to support the following development into a standardized product through the Horizon 2020 Programme. Horizon 2020 allowed us to further test and improve the prototype that was officially launched in Stockholm in September 2016. Important activities at this stage is the dissemination of BB Green which has developed into a well-known brand-name through marketing and PR-activities at numerous conferences and media contacts.

Demo Ship - AiriEl

AiriEl is the name of the prototype which is being used as a demo vessel. Leaving Riga in September 2016, the tour went to Stockholm for launching. Then through Göta Canal to Gothenburg, continuing to Sandefjord, Norway where the vessel is currently moored.

AiriEl has been used primarily for test and trials but many potential customers has gone for a ride and experienced its soft yet train-like ride comfort. They have also given their feed-back about the vessel that will be considered when BB Green comes into production.

BB GREEN - The Commuter

BB Green is challenging the car as a commuter. In many cities there is a lot of traffic congestion prolonging travel time and causing hazardous emissions. As many cities for historical reasons are situated along waterways, there are opportunities to return to the old times and use the waterways for commuting. However, this time with high speed and no emission thanks to new technology. It would be troublesome to introduce diesel driven high-speed ferries consuming hundreds of litres per hour in times when use of diesel is being banned in city centres. Furthermore, as the operational costs are much lower with BB Green the ticket price will be pretty affordable.

For the passenger, commuting with BB Green offers a number of benefits:

  • Fast commuting to city centre
  • Clean air and low noise
  • Time to work while traveling
  • Pleasant surroundings (compared to queuing on a highway)


There will be changes in the ferry market. Either because of new regulations or because of economy. It always comes down to economy. However, green economy is not only green but often more profitable. This depends on which country it concerns. The electricity price ranges from 3 cents to 20 cents per kWh in Europe while the diesel price varies between 20 and 70 cents per litre. The energy cost for operating a battery driven BB Green can be as low 10 % of a traditional diesel driven high-speed catamaran. Not to mention the maintenance costs which also are in the range of 10 %.
The investment in a battery boat is about the same as for a traditional high-speed ferry. The batteries in BB Green will last some 10 years, while light duty diesel motors will last only 3 – 5 years.
So even if there are no new regulations, BB Green makes the bottom line look better.
The hybrid version HB Green operates mainly with diesel motors but the hull efficiency in combination with using batteries in low-speed areas will reduce fuel consumption as well as emissions by some 50 % compared to traditional high-speed ferries.
