EETF: Composite Flywheels Wind Diesel Hybrid System

Project Overview

Flywheel technology is useful in remote environments due to their ability to store large amounts of energy in a similar size space with less hazardous chemicals in such a high concentration. Flywheels store energy as rotational energy that is supplied into a rotating disc or cylinder. This energy is then taken from the disc via an electrical generator.

Project Objectives

The Hatch project team will provide a report detailing application scenarios such as load profiles, flywheel sizing with regards to the wind turbine and genset ratings, required ancillary equipment, wind information and other pertinent data. The Hatch project team will provide ACEP with weekly data sets of tests that have been performed.


This project will utilize composite materials in their flywheel design to determine what material is best suited for different environments.

Administration of Funds

The Alaska Energy Authority has been placed in charge of administration for the Emerging Energy Technology Fund projects. More information can be found on their website here
