Whereas Leah Ellis was incomes her doctorate at Dalhousie College in Nova Scotia, she was a part of a group that did battery analysis for Tesla. After she graduated, her budding profession took an uncommon flip.
“I may have gotten a neater job with my background in battery supplies — loads of my colleagues go work for Tesla or Apple. I may have performed that, … and I might have made more cash at first,” Ellis, 33, informed CNBC by cellphone Wednesday.
As a substitute, Ellis utilized for and received 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 also be a serial clean-tech entrepreneur. Chiang co-founded firms corresponding to American Superconductor Company, A123 Methods, Desktop Steel, Type Power and 24M Applied sciences.
Now Ellis is working to scale up a brand new climate-conscious course of of creating cement, one powered with electrochemistry as an alternative of fossil fuel-powered warmth.
Making cement utilizing electrochemistry was Chiang’s concept, Ellis informed CNBC in Boston on the finish of Might. Ellis mentioned she labored with Chiang in 2018, simply after he had began Type Power, a long-duration battery firm, and he was fascinated by the plentiful intermittent vitality that was being generated by renewable vitality sources corresponding to wind.
“Generally folks can pay you to take vitality off their palms,” Ellis informed 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 may in any other case be very carbon-intensive? After which the primary on the listing of issues which are carbon-intensive — it is cement.”
Cement is a needed ingredient in concrete, which is the cornerstone of world 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 absolutely loaded airplanes, of cement is produced every year, in keeping with a 2023 report from administration consulting firm McKinsey. The worth of the market was $323 billion in 2021 and is predicted to achieve $459 billion by 2028, in keeping with SkyQuest Expertise Consulting.
Cement powder is conventionally made by crushing uncooked supplies, together with limestone and clay, mixing with substances corresponding 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 creating cement generates roughly 8% of world carbon dioxide emissions, that are a number one trigger of world warming.
When Chiang had the concept to affect cement manufacturing, he turned to Ellis. “He is tremendous busy, so he was like, ‘Go off and determine it out,'” Ellis informed CNBC.
So she did.
In 2020, Ellis and Chiang co-founded Chic Methods 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 Power’s Superior Analysis Tasks Company-Power, 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 Methods does within the cement-making course of.
“I believe for the layperson, it is best for them to know how we take that high-temperature, fossil-driven course of and change it with one thing that’s powered by electrons. And we’re utilizing electrons to push these chemical reactions,” Ellis informed CNBC by cellphone Wednesday. “That occurs at an ambient temperature under the boiling level of water,” she mentioned, and that may be a vital differentiator.
Ellis mentioned she did not know a lot about cement when Chiang bade her to go work out how one can 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 printed in scientific journal articles on the subject. That led to the idea for what Chic is doing now, and he or she’s continued to refine that idea ever since.
“And mainly simply have not stopped,” Ellis informed 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 loads of books,” she mentioned. “I all the time had that thirst for data and a way of journey.”
She additionally grew up in a non secular 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 after they had been each in Israel. “Jerusalem has greater than sufficient rabbis. So he moved to jap Canada, the place they do not have loads of rabbis,” Ellis informed CNBC of her father’s transfer. Her household celebrated and inspired having a sturdy mental life.

Ellis and considered one of 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 tough topic. And I believe we each kind of gravitate to issues which are difficult,” Ellis informed CNBC.
When mastered, chemistry can be utilized to impact change. “It has loads of artistic energy to make issues occur in the true world,” Ellis mentioned. “It is virtually like magic. Should you work actually laborious on it, you may 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 mentioned. “They do not go to the identical conferences.”
However with Chic Methods, Ellis and Chiang are bringing these two fields collectively.
That framework of utilizing electrochemistry to drive reactions that when occurred with very popular fossil fuel-powered reactions will not be unique to cement.
“It is an enormous software. I do not suppose Chic is the one one which’s making use of electrochemistry to wash tech. I believe one of the simplest ways now we have to get round fossil fuels is to make use of electrons,” Ellis informed CNBC.
“The electrochemical means is usually extra environment friendly,” she mentioned. “Heating issues as much as make them go is usually not as environment friendly as electrochemistry, which is a little more surgical, a bit extra environment friendly — or not less than might be extra environment friendly with the appropriate processes.”
That basic vitality effectivity is why Chiang is assured of their answer.
“Decarbonizing cement manufacturing goes to be a really powerful process. There will likely be quite a few approaches, all of which have challenges and most of which should be examined,” Chiang informed CNBC. “I favor to face our challenges as a result of we see a pathway to finish decarbonization at price parity with right this moment’s cement whereas consuming the least quantity of vitality. In the long term, the lowest-energy course of often wins.”

The cement trade wants to wash 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, informed CNBC. Motivations to go inexperienced are highest for producers positioned in components of the world corresponding to Europe, the place there’s a value on carbon dioxide emissions at round 80 euros (virtually $88) per metric ton. That is “a giant monetary penalty for producers and it provides them an incentive to take a position” in inexperienced cement tech, Mutter informed CNBC.
That is one purpose buyers are placing cash behind Chic.
“Prospects are lining as much as companion 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, companion at LowerCarbon Capital, informed CNBC.
“For Lowercarbon, their omnipresence and medieval manufacturing strategies are exactly the qualities that make constructing supplies such an irresistible alternative,” Dumas informed CNBC.
Some cement producers are carbon seize applied sciences as a technique to handle their greenhouse gasoline emissions. However “that is extremely pricey, and in some respects is simply enterprise as typical and burying the issue for future generations,” Mutter informed 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, mentioned Katie Rae, CEO at The Engine. “Producing decarbonized cement instantly, slightly than doing carbon seize, drives each vitality effectivity and eventual price parity,” Rae informed CNBC.
Dumas mentioned Chic has “essentially the most elegant chemistry, which runs on electrical energy at ambient temperatures whereas emitting zero carbon. Meaning they don’t have any want for giant ovens or pricey CO2-capture programs that may drive up capex.”
Siam Cement Group seems to be at hundreds of firms and makes solely “a number of” investments a yr, Tim McCaffery, a enterprise investor at SCG, informed CNBC. For SCG, what’s engaging about Chic is that it avoids the sophisticated and costly carbon seize know-how and works with present infrastructure.
“We’ve seen that Chic Methods may disrupt the trade. The corporate produces a cement at room temperature that may drop into the present prepared combine provide chain and meets American Society for Testing and Supplies requirements,” McCaffery informed CNBC. American Society for Testing and Supplies is the physique that creates check requirements and protocols that producers use to check their supplies in opposition to.
Climbing stairs, making options, shifting 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 targeted on getting the product to companions, and the corporate hopes to do its first building mission by the top of the yr. 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 pace is important within the race to decarbonize. “My mission is to have a swift and big impression on local weather change,” she informed CNBC in Boston.

It is an audacious objective, 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 informed 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 believe, who acknowledge the truth that I’ve loads of vitality, and I’ve loads of ardour. And I’ll work as laborious as I can for so long as I can to make this occur.”
Ellis is aware of how one can hold herself going, too. She makes positive she will get good sleep and he or she 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 informed CNBC. “I simply know how one can toe that effort line to similar to keep the identical effort for a really very long time, and to maintain my very own spirits up.”
For Chiang, constructing options retains him shifting ahead.
“It has been about 15 years because the 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 informed CNBC.
“I imagine local weather change has pushed all of us into an especially fertile, artistic interval that will likely be regarded again on as a real renaissance. In spite of everything, we’re making an attempt to re-invent the technological instruments of the commercial revolution. There is no scarcity of nice issues to work on! And time is brief.”
