Many industrial processes require high temperatures traditionally achievable only by burning fossil fuels.Rondo Energy is stepping into the space with their heat battery - a battery that stores energy from intermittent renewables in the form of heat, and then releases it as needed.I invited John O'Donnell, CEO of Rondo Energy to come on the podcast to tell me all about it.He very graciously obliged and we had an excellent discussion talking about The scale of the problem Rondo are seeking to address, how they are addressing it, and how they plan to scale to gigatonnes of CO2 saved per year.This was a truly fascinating episode of the podcast and I learned loads as always, and I hope you do too.If you have any comments/suggestions or questions for the podcast - feel free to leave me a voice message on my SpeakPipe page, head on over to the Climate 21 Podcast Forum, or just send it to me as a direct message on Twitter/LinkedIn.
