Sublime Systems Carbon Zero Cement Manufacturer received an investment tax credit of $ 46.7 million on January 16 from the United States Department of Energy and the Internal Income Service, allowing the firm. Advance on the construction of a cement plant of $ 150 million in Holyoke, mass.
Sublime has signed an agreement to acquire 16 hectares in Holyoke, and the plant will be fed by hydroelectric, helping sublime to achieve its zero carbon goals for its fully electrified cement manufacturing process.
Sublime cement occurs through a process developed for the first time at the Massachusetts Institute of Technology. Traditional The cement is made of limestone, which becomes clinker and then cement. This process releases carbon dioxide in the atmosphere. Today, cement production represents 8% of world carbon emissions.
The electrochemical process of sublime uses electrical energy to break down the raw materials in its constituent elements. Then set up the cement components. Sublime cement is made without limestone or fossils ovens. That of the company Cement fabrication technology can be fed by renewable sources, such as hydroelectric energy, and processes allow electrons to break down ingredients at room temperatures, instead of the traditional method of heating limestone and clay, clay, Mixed with iron ore or fly ash, in an oven of up to 2,700 ° F. The final cement product can serve a Portland cement replacement in construction projects, with similar performance features.
“This investment builds an even more resistant path towards the manufacture of L’Escala in the United States,” said Joe Hicken, Vice President of Sublime Business and Policies Development, who helped ensure the DOE grant. “We are very excited about the energy of space and investments and how we plan to make the manufacture on the ground in a space that, right now, about 20% to 30% of the materials we use. Foreign. It is a way to make us more locally. ”
Sublime’s cement has been used in concrete in projects of the Turner Construction contractor in the Boston area, and the contractor reported that he was given in trucks ready just like in other jobs.
Hicken said sublime is still in the first estimates of plant costs and its total engineering cost could change earlier than construction began at the end of this year or early 2026, with a finishing date scheduled for by 2027 or 2028.
Holyoke is known colloquially as a City paper, after producing 80% of the nation’s writing document by the end of 19th Century. The industrial site that Sublime plans its future plant is a property that formerly housed mills of paper.
