Air Liquide Partners with Solidia Technologies to Reduce CO2 Footprint of Pre-Cast Concrete

Air Liquide has partnered with US start-up Solidia Technologies^®, to provide a new equipment for carbon dioxide (CO₂) injection for the production of Solidia Concrete™, which is made with a new sustainable cement.

Thanks to Solidia’s patented processes that cure concrete with CO₂ instead of water, this next generation cement will allow the entire industrial chain to reduce the environmental footprint of pre-cast concrete of up to 70%.

Specially designed by Air Liquide in collaboration with Solidia, the new equipment for CO₂ injection and curing will demonstrate the feasibility of commercial-scale production of sustainable Solidia Concrete™. The breakthrough technology results in reduced concrete curing times of less than 24 hours and lower water consumption. In addition to capturing large amounts of CO₂, the concrete has higher quality performance.

In addition to supplying the equipment, Air Liquide will serve as the worldwide preferred provider of carbon dioxide for use with Solidia’s patented processes. The concrete manufacturers’ customers will be able to buy CO₂-cured Solidia Concrete™ products this summer in North America and in Europe next year.

In addition to this partnership, Air Liquide Venture Capital (ALIAD) has also invested in Solidia Technologies^® to support the industrialization of the technology.
