THE CHALLENGE
Electricity cannot be easily stored
• Renewable power cannot be scheduled• Renewable power cannot be scheduled• Must balance supply and demand • Required at small and large scale• Energy storage required for long periods• Energy storage required for long periods• Represents major barrier to adoption of renewables
