Innovation, sustainability and the future of cities
I started this thread of posts to discover whether electricity storage is a major barrier to wider deployment of renewables. So, what have we learned about electricity storage over the last nine weeks? Renewable energy has not created the need
Last week we talked about batteries for grid scale electricity storage. There is another way we can use chemical bonds to store spare renewable electricity – Power-to-X. The idea behind Power-to-X is to convert renewable electricity into a transportable and
This week we look at using batteries for temporary storage of renewable electricity. The installed battery capacity is still small compared to pumped hydro, but it is the fastest growing solution, and the most flexible. Battery is a generic term
Last week, I looked at the wide range of technologies available for electricity storage to support renewable energy grids. Gravity systems are the dominant form of electricity storage today. Current installations can store up to 9,000 GWh—about a quarter of
I get frustrated that any time renewable energy and net-zero get mentioned on social media, reporting a new technical breakthrough, a bigger pipeline of projects or reducing costs, someone will triumphantly reply “you know the sun doesn’t shine at night!”,
This week is my first anniversary as a battery electric vehicle driver. My previous car had reached the end of its economic life and I had promised myself that my next vehicle would be electric. There is little to say
