Brimstone Energy

Company Overview

Brimstone Energy aim to transform the cement industry from climate problem to climate solution. Cement is one of the most used materials on the planet. It's also a huge source of global emissions. 

Over 4 billion tons of cement are produced each year — a number only expected to grow. The problem is that cement production accounts for 7.5% of global CO2 emissions, with a total climate impact just behind cars. In fact, if the cement industry were a country, it would be the third-largest emitter in the world.

Brimstone Energy are here to change this with their breakthrough carbon-negative process for making ordinary Portland cement. It’s the same material builders have relied on for 150 years, just now with a positive climate impact.

Brimstone Energy's Impact

Brimstone Energy believe that to make the greatest impact for the climate, entire industries need to transform — fast. They are a team of scientists, problem-solvers, engineers, innovators, and builders on a mission to solve the hardest climate problems and accelerate the evolution of critical industries for the climate era in an economically competitive way. They start with cement.

Brimstone Energy's Mission and Values

• Carbon-negative: The Brimstone Process™ is carbon-negative, removing CO2 from the air.

• Low cost: The Brimstone Process™ is cost-competitive at scale.

• Zero trade-offs: The Brimstone Process™ makes cement that is chemically and physically identical to conventional Portland cement.

Current Investors

Currently backed by leaders in climate tech such as Breakthrough Energy Ventures, The Climate Pledge, Impact Science Ventures, Amazon, Fifth Wall, Plug and Play Milan, DCVC and many others.

Brimstone Energy's Growth Strategy and Use of Funds

They are in the process of securing advance commitments for their first commercial plant, planning for the commercial launch of their technology is underway and coming soon.

They are working with tirelessly with industry leaders and other key partners to scale their technology and maximise its impact on climate change.

They are also actively hiring individuals motivated to make a significant impact in reducing global emissions and to build the future with them.

The money raised will be used to build their first industrial plant to create their cement; the company plans to start production in 2023.

Risks Associated with Brimstone Energy

One challenge is that the concentration of lime in the calcium silicate rocks is lower than that of limestone. That requires processing more rock — anywhere from 30 to 250 percent more — to yield the same amount of lime. But because Brimstone’s process doesn’t include fly ash, the total tonnage of material required is comparable to that used by other cement makers.

Introducing new cements into the market is notoriously difficult, said Ian Riley, CEO of the World Cement Association. Manufacturers of structural concrete are limited by different construction standards and specifications as to what components and ingredients can be put into it.

Brimstone intends to work with existing cement companies, like HeidelbergCement, LafargeHolcim, or others and integrate their process into the larger operation of those multinational cement manufacturers.

“This isn’t carbon capture, or a cement alternative. Brimstone’s technology doesn’t change the chemistry of Portland cement. It’s a clean process with no CO2 by-product that also produces SCM without burning coal," Kelly Chen, Partner at DCVC, said. "Our investment in Brimstone exemplifies DCVC’s work of over a decade backing brilliant entrepreneurs solving trillion-dollar problems at the forefront of climate resiliency.”
