Energy storage solutions for offshore wave and tidal energy prototypes

This paper investigates the motivations for energy storage solutions for offshore Wave Energy Converters (WEC) and tidal energy prototypes. It examines the power and energy storage solutions on offer for developers to aid them during the design stage. Energy storage solutions examined include lead acid batteries, lithium ion batteries, supercapacitors, lithium ion capacitors and diesel for diesel generators. A focus is placed on key installation, operation and maintenance requirements associated with the apparent suitable technologies which are often overlooked. A case study examining a tidal developer's energy storage needs is then presented.
