The Viking Queen, a 6,000-ton vessel built in 2008, is the first of its kind to use a battery energy storage system (BESS) to help reduce fuel consumption and emissions for a greener, more efficient power supply.
Nidec ASI, an Italian company that specializes in power electronics and industrial automation, retrofitted the Norwegian ship with the energy storage system to prove that on-board batteries are the solution to making vessels more energy efficient.
The use of the BESS reduces the ship’s fuel consumption by approximately 18% and helps the vessel reduce nitrogen oxide, carbon dioxide and other greenhouse gas emissions by approximately 25%. The project demonstrates that it is possible to achieve reductions for emissions even for existing vessels.
According to market research firm IHS, the energy storage market is set to “explode” to an annual installation size of 6 gigawatts (GW) in 2017 and over 40 GW by 2022 — from an initial base of only 0.34 GW installed in 2012 and 2013. Flywheel energy storage and BESSs are operating today in the competitive ancillary services power market — “providing a 10x faster and more accurate response to a power dispatcher’s signals compared to power turbine generators.”
BESSs are currently being tested for use in other scenarios as well. Hawaiian Electric is researching if the use of such a system can deliver power during periods of peak energy use. And a suburb of Chicago recently announced it is investigating the value of battery technology such as BESSs to reduce the impact of power outages.
