Whereas Leah Ellis was incomes her doctorate at Dalhousie College in Nova Scotia, she was a part of a crew that did battery analysis for Tesla. After she graduated, her budding profession took an uncommon flip.
“I might have gotten a better job with my background in battery supplies — quite a lot of my colleagues go work for Tesla or Apple. I might have performed that, … and I might have made more cash at first,” Ellis, 33, advised CNBC by telephone Wednesday.
As a substitute, Ellis utilized for and gained a prestigious Banting Postdoctoral Fellowship that granted her two years’ wage to work with whomever she needed.
Ellis took her Ph.D. in electrochemistry and went to work for But-Ming Chiang, a famend materials sciences professor at Massachusetts Institute of Expertise who can be a serial clean-tech entrepreneur. Chiang co-founded corporations akin to American Superconductor Company, A123 Programs, Desktop Steel, Type Vitality and 24M Applied sciences.
Now Ellis is working to scale up a brand new climate-conscious course of of constructing cement, one powered with electrochemistry as an alternative of fossil fuel-powered warmth.
Making cement utilizing electrochemistry was Chiang’s concept, Ellis advised CNBC in Boston on the finish of Could. Ellis stated she labored with Chiang in 2018, simply after he had began Type Vitality, a long-duration battery firm, and he was enthusiastic about the ample intermittent vitality that was being generated by renewable vitality sources akin to wind.
“Typically folks pays you to take vitality off their palms,” Ellis advised CNBC. “As a substitute of placing that vitality in a battery, what if we are able to use this additional low-cost renewable vitality to make one thing that might in any other case be very carbon-intensive? After which the primary on the record of issues which can be carbon-intensive — it is cement.”
Cement is a crucial ingredient in concrete, which is the cornerstone of worldwide building and infrastructure, as a result of it is low cost, sturdy and sturdy. 4 billion metric tons, which is the equal of fifty,000 totally loaded airplanes, of cement is produced annually, in line with a 2023 report from administration consulting firm McKinsey. The worth of the market was $323 billion in 2021 and is anticipated to achieve $459 billion by 2028, in line with SkyQuest Expertise Consulting.
Cement powder is conventionally made by crushing uncooked supplies, together with limestone and clay, mixing with substances akin to iron and fly ash, and placing all of it right into a kiln that heats the substances as much as about 2,700 levels Fahrenheit. That course of of constructing cement generates roughly 8% of worldwide carbon dioxide emissions, that are a number one trigger of worldwide warming.
When Chiang had the thought to impress cement manufacturing, he turned to Ellis. “He is tremendous busy, so he was like, ‘Go off and determine it out,'” Ellis advised CNBC.
So she did.
In 2020, Ellis and Chiang co-founded Chic Programs to refine and scale up the electrochemical course of they created for making cement.
Chic has raised $50 million from some main clean-tech buyers, together with Chris Sacca’s LowerCarbon Capital and Boston-based, MIT spin-out enterprise agency The Engine; from Siam Cement Group, a number one cement and constructing supplies firm in Asia; and by way of a few grants from the U.S. Division of Vitality’s Superior Analysis Tasks Company-Vitality, or ARPA-E, program.

Ellis likes to explain what they’re doing as creating the “electrical automobile of cement making.” An electrical automobile replaces a combustion engine with an electrical motor, and that is what Chic Programs does within the cement-making course of.
“I feel for the layperson, it is best for them to grasp how we take that high-temperature, fossil-driven course of and substitute it with one thing that’s powered by electrons. And we’re utilizing electrons to push these chemical reactions,” Ellis advised CNBC by telephone Wednesday. “That occurs at an ambient temperature beneath the boiling level of water,” she stated, and that could be a essential differentiator.
Ellis stated she did not know a lot about cement when Chiang bade her to go work out the best way to make low-carbon cement. She began by studying Wikipedia, after which textbooks. Then she labored with one other Ph.D. scholar doing analysis that was later revealed in scientific journal articles on the subject. That led to the idea for what Chic is doing now, and she or he’s continued to refine that idea ever since.
“And principally simply have not stopped,” Ellis advised CNBC. “It has been 5 years.”
Bringing the ‘magic’ of chemistry to cement
Ellis has all the time been curious. “I grew up fairly nerdy, I suppose, studying quite a lot of books,” she stated. “I all the time had that thirst for information and a way of journey.”
She additionally grew up in a spiritual family. Her father is an Orthodox Jewish rabbi from Texas, her mom grew up on a sheep farm in South Africa, and the 2 met once they had been each in Israel. “Jerusalem has greater than sufficient rabbis. So he moved to japanese Canada, the place they do not have quite a lot of rabbis,” Ellis advised CNBC of her father’s transfer. Her household celebrated and inspired having a sturdy mental life.

Ellis and one among her two youthful sisters ended up getting their doctorates in chemistry.
“Each of us notice that chemistry is a really artistic topic; it is also a really troublesome topic. And I feel we each form of gravitate to issues which can be difficult,” Ellis advised CNBC.
When mastered, chemistry can be utilized to impact change. “It has quite a lot of artistic energy to make issues occur in the actual world,” Ellis stated. “It is nearly like magic. In the event you work actually exhausting on it, you’ll be able to create issues that make the world a greater place.”
Battery scientists and cement producers haven’t traditionally labored collectively. “Cement sometimes sits in civil engineering, and battery science usually sits in chemistry or physics,” Ellis stated. “They do not go to the identical conferences.”
However with Chic Programs, Ellis and Chiang are bringing these two fields collectively.
That framework of utilizing electrochemistry to drive reactions that when occurred with highly regarded fossil fuel-powered reactions isn’t unique to cement.
“It is an enormous device. I do not suppose Chic is the one one which’s making use of electrochemistry to scrub tech. I feel the easiest way we’ve to get round fossil fuels is to make use of electrons,” Ellis advised CNBC.
“The electrochemical method is commonly extra environment friendly,” she stated. “Heating issues as much as make them go is commonly not as environment friendly as electrochemistry, which is a little more surgical, a bit extra environment friendly — or at the least will be extra environment friendly with the correct processes.”
That elementary vitality effectivity is why Chiang is assured of their answer.
“Decarbonizing cement manufacturing goes to be a really powerful job. There will probably be quite a few approaches, all of which have challenges and most of which need to be examined,” Chiang advised CNBC. “I choose to face our challenges as a result of we see a pathway to finish decarbonization at value parity with as we speak’s cement whereas consuming the least quantity of vitality. In the long term, the lowest-energy course of normally wins.”

The cement trade wants to scrub up store
“On the entire, the trade is very motivated to go inexperienced,” Mark Mutter, the founding father of Jamcem Consulting, an unbiased cement trade consultancy, advised CNBC. Motivations to go inexperienced are highest for producers positioned in elements of the world akin to Europe, the place there’s a value on carbon dioxide emissions at round 80 euros (nearly $88) per metric ton. That is “an enormous monetary penalty for producers and it provides them an incentive to speculate” in inexperienced cement tech, Mutter advised CNBC.
That is one purpose buyers are placing cash behind Chic.
“Clients are lining as much as associate with Chic as a result of they will provide fossil-free cement at a time when the remainder of the trade are all struggling to hit emissions targets and adjust to carbon tariffs,” Clay Dumas, associate at LowerCarbon Capital, advised CNBC.
“For Lowercarbon, their omnipresence and medieval manufacturing strategies are exactly the qualities that make constructing supplies such an irresistible alternative,” Dumas advised CNBC.
Some cement producers are taking a look at carbon seize applied sciences as a solution to handle their greenhouse gasoline emissions. However “that is extremely expensive, and in some respects is simply enterprise as regular and burying the issue for future generations,” Mutter advised CNBC.
Chic is making clear cement with out the costly additive of carbon seize and storage applied sciences, which is engaging as a result of it retains prices low, stated Katie Rae, CEO at The Engine. “Producing decarbonized cement instantly, quite than doing carbon seize, drives each vitality effectivity and eventual value parity,” Rae advised CNBC.
Dumas stated Chic has “probably the most elegant chemistry, which runs on electrical energy at ambient temperatures whereas emitting zero carbon. Meaning they don’t have any want for large ovens or expensive CO2-capture techniques that might drive up capex.”
Siam Cement Group seems to be at 1000’s of corporations and makes solely “a number of” investments a 12 months, Timothy McCaffery, a enterprise investor at SCG, advised CNBC. For SCG, what’s engaging about Chic is that it avoids the difficult and costly carbon seize expertise and works with present infrastructure.
“We’ve seen that Chic Programs might disrupt the trade. The corporate produces a cement at room temperature that may drop into the prevailing prepared combine provide chain and meets American Society for Testing and Supplies requirements,” McCaffery advised CNBC. American Society for Testing and Supplies is the physique that creates check requirements and protocols that producers use to check their supplies towards.
Climbing stairs, making options, transferring ahead
Chic accomplished its pilot plant on the finish of 2022 and spent a number of months on high quality management measures. Now, Ellis is concentrated on getting the product to companions, and the corporate hopes to do its first building undertaking by the top of the 12 months. The subsequent step is to go from the 100-ton pilot plant to a 30,000-ton-per-year demonstration plant.
Whereas Chic is simply getting ramped up, Ellis is aware of velocity is crucial within the race to decarbonize. “My mission is to have a swift and big influence on local weather change,” she advised CNBC in Boston.

It is an audacious aim, and whereas Ellis has credentialed chemistry chops, that is her first time being the boss of an organization.
“I suppose I’m conscious of my age. And I am additionally humble about that. I am a first-time founder. I am a first-time CEO,” Ellis advised CNBC. “I determine issues out as I do them. And I am actually fortunate to have nice mentors and help and individuals who imagine in me, and, I feel, who acknowledge the truth that I’ve quite a lot of vitality, and I’ve quite a lot of ardour. And I will work as exhausting as I can for so long as I can to make this occur.”
Ellis is aware of the best way to maintain herself going, too. She makes positive she will get good sleep and she or he stays lively. She’s run seven marathons. She’s a cycler, and as soon as cycled throughout Africa in about 4 months with a bunch, a visit that averaged out to driving greater than 60 miles a day. She additionally participates in a “health cult” that climbs the Harvard stadium stairs each Sunday.
“I am not a quick runner in any respect. I am not a quick bike owner both,” Ellis advised CNBC. “I simply know the best way to toe that effort line to similar to preserve the identical effort for a really very long time, and to maintain my very own spirits up.”
For Chiang, constructing options retains him transferring ahead.
“It has been about 15 years for the reason that phrases ‘local weather change’ entered the lexicon. It has been a present, and really energizing, to have doubtlessly impactful options to pursue, versus sitting and fretting,” Chiang advised CNBC.
“I imagine local weather change has pushed all of us into an especially fertile, artistic interval that will probably be appeared again on as a real renaissance. In spite of everything, we’re making an attempt to re-invent the technological instruments of the economic revolution. There is no scarcity of nice issues to work on! And time is brief.”
