Siam Cement Group (SCG) has invested in Rondo Energy, joining decarbonisation investment firm Energy Impact Partners and Bill Gates’ Breakthrough Energy Ventures.

Rondo and SCG will be collaborating under a letter of intent to develop and expand the use of Rondo’s Heat Battery (RHB) technology.

RHB stores renewable electricity in the form of high-temperature heat in brick. The stored heat is delivered on demand at temperatures up to 1500°C.

According to Rondo, the Heat Battery delivers the reliable, continuous energy supply industry needs, while capturing the lowest-cost, lowest-carbon energy in the world today: intermittent wind and solar power. 

The aim is that Rondo’s technology will help decarbonise SCG’s lines of business including cement, chemicals, paper, and packaging. 

SCG’s investment will support earlier deployments of the Rondo Heat Battery, which reduces operating costs for the world’s biggest energy users – heavy industry – while eliminating Scope 1  and Scope 2 emissions.

Rondo will use this funding to scale its manufacturing capacity, originate customer projects, and develop services for both heavy industry and energy producers.

Rondo and SCG expect this collaboration to support rapid production and deployment of RHBs across Southeast Asia and worldwide. The companies plan to work together on large-scale renewable energy projects that decarbonise energy-intensive industrial operations. 

John O’Donnell, CEO of Rondo Energy, said: “Rondo is excited to be working with SCG. Our technology opens a new pathway for SCG to achieve their deep decarbonisation goals and simultaneously reduce their operating costs. 

“SCG’s deep capabilities in execution and quality will enable Rondo to deliver reliable energy infrastructure rapidly and at scale. Together, Rondo and SCG have the global footprint to deliver deep decarbonisation projects, including Heat as a Service projects in Southeast Asia and worldwide.”

Tim McCaffery, global investment director at SCG, said: “SCG has been leading and investing in strong decarbonisation technologies with the goal to achieve net-zero emissions by 2050.

“Rondo has a heat battery technology to reduce CO2 emissions in manufacturing operations. Together with Rondo, SCG is excited to bring this technology to the region to reduce greenhouse gas emissions and limit global warming.”
