US Marine Corp utilising microgrid energy storage project

An innovative flywheel storage system is proving effective for a microgrid serving the US Marine Corp in California.

The Corp was allocated funds in the amount of $1.7 million by the California Energy Commission in 2013 to implement a microgrid project and the flywheel storage system, designed by Quantum Energy Storage Corporation, is in charge of providing vital energy storage that enables many applications for the facility.

The project at the base will gauge the value of the latest technologies in a real-world environment, all the while supplying reliable and secure energy to the US Marine Corp.

The project, which is integrated within CleanSpark’s FractalGrid project, establishes a network of smaller microgrids. These interconnected microgrids covers a base area that include military staff housing, garage lighting, elevators and a server room. These microgrids are nested within a bigger-scale microgrid that services the base and have an islanding option.

Distributed generation at the base include solar panel systems, diesel gensets, batteries and the initial test run of Quantum‘s 60 kW, 120-kWh kinetic energy storage system.

QESC kinetic storage lifespan is estimated at 25 years and it can go through 50,000 cycles without deterioration. It compares favourably to batteries, which degrade and utilize dangerous and polluting chemicals. Kinetic energy storage by Quantum comes with a software platform that manages the system.

The management platform lends itself to extensive customization at a low cost in microgrids. This is possible because the system is flexible and can be conveniently integrated with distributed assets, such as  solar PV and building systems.

Flywheel storage intends to decrease dependence on diesel generators by as much as 40 percent by replacing or eliminating spinning reserves.

In addition it works as a backup power source for extended nighttime periods, averaging 10 hours. During the day, it serves to supply power for systems like the elevators, which put considerable strain on the grid. This additional energy boost shaves peaks and provides relief. Plans for future storage uses include grid balancing and correcting the power factor.
