Just have a Think - Flywheel reinvention revolutionising our power grids, 01012023

Flywheels are an ancient technology going right back to the potters wheels of 3,000BC. But this simple technology is now being developed to provide kinetic inertia that can help stabilise the voltage frequency of utility grids around the world. So could this be another step on the way to full grid decarbonisation in the coming years?

Undecided - How A Sand Battery Could Change The Energy Game, 30082022

Efficient energy storage systems are the conundrum of making the most out of intermittent renewable energy. It’s a glaring problem we have to solve, which is why so many different battery technologies are being explored and developed. To the point that some of them are now coming out of the sand … that’s what recently happened in Finland where the world’s first commercial sand battery technology went live this past July. How does it work and is it a viable path for storing energy?
