CalPortland Signs Patent License Agreement With Solidia

Taiheiyo Cement Corp. announced that its subsidiary, CalPortland Company (CPC) has signed a license agreement with Solidia Technologies Inc., a Texas-based company specializing in low-carbon cement and concrete, regarding patents focused on reducing CO2 emissions. 

Taiheiyo Cement Group implemented its “Carbon Neutral Strategy 2050” with the aim of achieving carbon neutrality throughout the entire supply chain by 2050. To achieve this goal, the group has devised a transition plan to reduce CO2 emission intensity by at least 20% from the 2000 level by 2030 through the utilization of established technologies, and complete the development of innovative technologies for CO2 capture and utilization.

CPC has joined the Portland Cement Association’s (PCA) “Roadmap to Carbon Neutrality” initiative and in addition to expanding its cementitious materials business and promoting the use of blended cement, CPC is actively engaged in industry-government-academia collaborations to develop and introduce innovative technologies and considering acquiring technologies from start-up companies to further enhance its efforts.

By leveraging Solidia’s innovative technology, CPC aims to develop and implement low-carbon solutions within the western United States (Washington, Oregon, California, Arizona, Nevada, and Idaho), where it operates. As part of its ongoing commitment to decarbonization, CPC established a “Carbon Reduction Team” in February 2024. This agreement serves to enhance CPC’s endeavors in decarbonization, contributing to its future initiatives in achieving carbon neutrality.

CPC also purchased certain lab and plant assets from Solidia.

“CalPortland continues to focus on decarbonization opportunities that lead to meaningful and innovative carbon reduction for the cement and concrete industries,” said Bill Mullen, CalPortland chief operating officer. “Our Carbon Reduction Team has worked diligently with Solidia Technologies to enter into this licensing agreement and asset purchase that will help us achieve our sustainability goals.”

“Solidia Technologies is excited to begin a new licensing program with CalPortland,” Russell Hill, CEO of Solidia stated. “CalPortland’s unwavering commitment to decarbonization of the cement and concrete industries makes it a great partner for continuing the vast development and research advanced by Solidia for more than a decade ago.”

Solidia Cement is a low-limestone cement that gains strength through carbonation — exposure to CO2 — rather than hydration like traditional portland cement. Solidia Cement is made using the same raw materials and equipment as portland cement; however, Solidia Cement achieves significant CO2 reductions from lower production temperatures and reduced limestone calcination. Solidia Cement can be utilized in the manufacture of both concrete products and supplemental cementitious materials.

Following the divestiture to CPC, Solidia expects to continue to work with licensing partners to provide its low carbon solutions embodied in more than 300 patents and patent applications across the globe.
