Industrial Decarbonization: Challenges & Opportunities
Energy-intensive industrial processes power our economies and produce our commodities. But, the high-temperature heat they require is the world’s largest source of CO₂ emissions. Until now, intermittent renewables have struggled to provide 24/7 high-temperature power needed by industry.
Solar and wind electricity are now lower cost than fossil fuels, worldwide. An ideal solution for industry must meet the following criteria. It must be:
Cost-effective: Energy is a fundamental component of overall production costs.
Continuous: Around-the-clock operations require a constant energy supply.
Really hot: 75% of industry’s energy requirement is heat, at up to thousands of degrees.

Why electrifying industrial heat is such a big deal
A full quarter of global energy use goes toward heat that powers industrial processes. To provide clean industrial heat but avoid the variability often associated with renewable energy, a company called Rondo makes a thermal battery, storing renewable-energy heat in bricks.

Catalyst: Solving the conundrum of industrial heat
In this episode, Shayle talks to John O’Donnell, co-founder and CEO of Rondo Energy, a thermal storage startup. (Shayle’s venture capital firm, Energy Impact Partners, has made investments in Rondo Energy.) They break down the challenges of industrial heat and discuss the range of technologies that could help generate it with low emissions.

TED Talk: Can a simple brick be the next great battery?
The world relies on manufacturing, and manufacturing relies on heat — a massive contributor to global carbon emissions, responsible for a quarter of the world's fossil fuel use. Energy entrepreneur John O'Donnell has figured out a better, cleaner way to generate the heat we need to make the stuff we want. Learn how his team turned simple bricks and iron wire into a powerful, unconventional "heat battery" that could deliver industrial heat at scale without the emissions — and why he thinks electrified industrial heat is the next trillion-dollar industry.
