Ocean Power Technologies (OPT) has launched a subsea battery storage device to provide energy for offshore activity such as powering remotely operated vehicles in sectors such as offshore wind.
OPT has developed the device using a lithium iron phosphate battery system with a nominal storage capacity of 132 kilowatt-hours.
Modular design allows multiple units to be linked together to meet larger energy requirements for various types of subsea equipment, including autonomous underwater vehicles as well as ROVs.
OPT chief executive George Kirby said: “The introduction of our subsea battery marks OPT’s second product launch this year.
“The ongoing electrification of subsea assets requires reliable power that can scale to meet the needs of the offshore industry. The Subsea Battery joins the recently unveiled hybrid PowerBuoy and our PB3 PowerBuoy to form an impressive suite of OPT power and communications solutions for remote ocean applications.”
The subsea battery provides uninterruptable power for long-term offshore installations requiring electric power, backup or emergency power for short term missions, and is scalable.
