The Renewable Energy Crisis
Renewables are not working due to:
1. Intermittency:

Renewables generate all the energy we need when we don't need
it, and not when we do
2. Government subsidies:

Direct

Indirect

The Storelectric Solution
Grid Scale Energy Storage
Using
Compressed Air Energy Storage (CAES)
©2014 Storelectric Ltd
What CAES Is
What it is

Take in surplus electricity

Use it to pump compressed air into a salt cavern

When demand exceeds supply, regenerate electricity
What it does

Store gigawatt hours per installation

Match supply with demand

The only technology that can, grid scale, today or soon
Proven and working reliably since 1978

But only 42-50% efficient

What We Have


3 patents pending using existing, proven technologies to increase
efficiency to 70-85% – and the threshold for viability is around 60%;
5 more patents written, for even greater efficiency;
 2 locations in the North West with salt caverns and local support;
 1-3GWh storage per installation, generating min. 250-500MW;
 Outstanding expertise within our team;
 A market for generating min. 27GW of peak (i.e. premium rate)
electricity and storing 2.5TWh in the UK alone;
 Ability to replicate throughout the country and world;
 A very strong business case based on conservative figures, with strong
profitability from a single installation.
