Low Carbon Cement is Sublime | Dr. Leah Ellis of Sublime Systems | Ep 132

In this episode, Joe Batir talks with Dr. Leah Ellis, CEO and co-founder of Sublime Systems. She discusses the environmental impact of cement production and the need for decarbonization. She explains the process of cement and concrete production and the challenges of carbon capture and storage (CCS). Dr. Ellis introduces Sublime Systems’ innovative process that replaces traditional cement production with a fossil fuel-free, electrochemical method. She highlights the potential for reusing existing concrete and the importance of addressing additional inputs and reducing emissions. Dr. Ellis also discusses the first commercial-scale manufacturing facility and the path to achieving net zero and beyond.

Takeaways

Cement production is a major contributor to global CO2 emissions, and decarbonizing the industry is crucial for achieving net zero.

Sublime Systems has developed an electrochemical process that replaces traditional cement production, reducing emissions and avoiding the use of fossil fuels.

The reuse of existing concrete and the reduction of additional inputs are important steps in minimizing the environmental impact of cement production.

Scaling up the production of Sublime Systems’ cement technology is essential for achieving significant emissions reductions in the industry.
