•
•
10% current UK gas fired heat viable rising to
approximately 44% depending on future energy
pricing
Medium heat extraction from large plant most
efficient – 120 degrees C
Could improve thermal plant efficiency (typically
35-55%) to approximately 80%
Flexibility provided through decoupling electricity
and heat generation
Seasonal storage capability
