Almost all new solar projects incorporate some energy storage to firm their output and provide dispatchable renewable power generation.
The benefits are clear, from increasing economic certainty, reducing risk and penalty costs (FCAS or MLF based) to increasing potential revenue streams and smoothing generation which may help with grid connection applications. Energy storage acts as an option to your asset – allowing you to move your energy production to times that the market will reward you for it.
What isn’t clear is the cost of this option via energy storage when using lithium ion, whether from degradation of the Li-Ion battery or parasitic HVAC losses (linked to local weather).
Long duration flywheels provide greater cost certainty, greater reliability for longer and greater economic return.
