Dr. Tom Feehally from Manchester University explained to us the changes occurring to our electricity supply as renewable/distributed generation increases, and the challenges this poses.
Technologies which exist for grid-connected energy storage – pumped hydro, compressed air, hydrogen, electro-chemical (batteries). But batteries that charge rapidly and hold a lot of power have been known to burst into flame! It would be useful to learn more about the technical challenges in this area.
How electric vehicles are going to change our energy usage, potentially reducing CO2 emissions but increasing electricity demand.
