An investigation into sustainable energy storage systems for buildings

University of British Columbia. Sustainability Office

This report documents the research that has been done on the use of Energy Storage Systems (ESS). To ensure the reliability of the alternative energy source for the new SUB, ESS needs to be incorporated in the energy system to store electricity at off-peak periods and release the energy at peak time. Three storage techniques are presented in the report, including the most traditional batteries, and two promising techniques— the flywheel system, and the superconducting magnetic energy system. Operation and implementation of every energy storage method is covered. In addition, each technique’s advantages and disadvantages are analyzed, and triple-bottom line analyses are made. Although battery is very reliable and has an energy density of about 80kwh/kg, it has a cost of over $1/kwh, and it is non-environmentally friendly; the flywheel is both reliable and efficient; the superconducting magnetic energy system is 97% efficient and reliable, still it is not cost-effective at small scale. Based on the cost, social and environmental impacts, the flywheel energy storage system is recommended for the new SUB.
