MTR100: Subsea Batteries
a constant output of power from renewable sources to support offshore decarbonization projects and minimize energy loss from electricity generated from offshore wind.Power management system advancements are key, but Verlume’s CTO, Paul Slorach, says the company is also continually improving the energy density of its systems. Most recently, that has involved a new module design, but he is also keeping an eye on the developments in the electric vehicle market and exploring new battery chemistries.DeepSea’s SeaBattery in use on one of the Five Deeps Expedition landers.

Kraken Robotics Wins $3M Order for SeaPower Subsea Batteries
;s SeaPower 6000-meter rated pressure tolerant batteries are based on Kraken’s unique pressure tolerant gel encapsulation technology for lithium polymer batteries," Kraken said.Kraken describes its batteries as "an attractively priced, environmentally friendly, and superior energy density alternative to the traditional oil compensated batteries commonly used for deep subsea battery applications."The batteries are hot-swappable and modular and include an integrated battery management system within each battery module which, Kraken says, provides a very high level of redundancy
Eni Installs "World's First" Inertial Sea Wave Energy Converter Offshore Pantelleria
. The power that could be generated from sea waves is estimated at around 2 terawatts globally, for a total of 18,000 terawatt-hours a year, almost the same as the entire planet’s demand for electricity," Eni said."Energy from sea waves is also more predictable, constant, and of higher energy density than that of the sun and wind, as it is available both during the day and at night. A further advantage of this technology is the considerable reduction of its impact on the landscape, since the device stands only 1 meter above sea water. "Moreover, ISWEC can be integrated perfectly with
Lander Lab #5: Lithium Polymer Batteries
;Safety remained paramount, as I began to get a handle on the technology a lot of others were already using.I have now used LiPos for several years in a variety of at-sea applications. The more you learn, the more successes you have, and the more possibilities present themselves. I respect their energy density, but also their willingness to do a job.There is a large body of work describing fundamentals of LiPo cells and their application. This article will cite some of them. In brief, always treat LiPo’s with the respect they deserve. It is crucial to stay within the

General Atomics Wins Contract for LDUUV Motor and ESS
two years, the motor has undergone lab testing, and power system has completed underwater testing. Both systems have performed successfully, demonstrating capabilities to both power and propel underwater vehicles. Together, the systems are proving to be key technologies to provide the combined power, energy density, and improved vehicle performance necessary to help meet the objectives.”Development and testing of both motor and power systems continues in order to optimize performance. An LDUUV with the integrated motor and power propulsion system eventually will undergo at-sea testing during a later
Innovative Tidal Power Project Proceeds in the Scottish Sea
the complete, fully integrated drive train as a "plug & play module" to Scotland. The 2MW drive trains, as used in the Scottish Orbital project, complement the generation of electricity from solar and wind power. The tides are reliable, the flow of electricity is predictable, and the energy density due to the working medium seawater is very high.Within the Orbital O2 drive trains, SKF core competence is not only found in the main bearings and in the slewing bearings for pitching the rotor blades, but also in the seawater seals of the main shafts between the rotor hub and the nacelle housing
