@Reuters: Solar and wind energy are now cheaper alternatives to fossil fuels. But its intermittent nature means that storing that power is a huge challenge. Rondo Energy is a start-up which aims to store that power as heat and cut reliance on lithium batteries https://t.co/ue6BLg8WoP

Rondo Energy is supplying cheap, zero-emissions heat to factories to replace fossil-fuel-powered boilers, furnaces, and kilns. Its approach of using bricks and iron wire to provide a steady supply of hot air or steam stands out for its simplicity and potential to scale.

Heat batteries have enormous potential to decarbonize industry, the next frontier in the path to net-zero. This report from RMI explains why rmi.org/thermal-batt... Disclosure: Im an advisor to Rondo Energy, the leader in this segment, and have an equity interest in the company. (And this is why!)

In 2020, Rondo Energy's founders were tinkering in a garage, trying to figure out how to stack bricks that could store renewable energy as heat. They ended up calling the fire department... twice. 🧵(1/5)

Rondo Energy co-founder and chief innovation officer John O’Donnell explains how the company decided to size the brick for their first commercial scale heat battery project: www.latitudemedia.com/news/how-big...

Rondo Energy is an interesting company. "By 2027, Rondo Energy plans to expand production to 90 gigawatt-hours annually." Materials science is amazing. “A pound of brick stores more energy than a pound of lithium-ion battery, at less than 10% of the cost.” www.cnbc.com/2024/12/06/w...
