Revealing no less than four new equity investments in technology start-ups last month, Air Liquide disclosed that it had acquired a stake in US start-up, Solidia Technologies®, contributing towards the development of a new sustainable concrete.

That investment has now been described by the Tier One corporation as a partnership, with the two companies teaming up to provide new equipment for carbon dioxide (CO2) injection.

The new equipment for CO2 injection and curing seeks to demonstrate the feasibility of commercial-scale production of sustainable Solidia ConcreteTM – resulting in reduced concrete curing times of less than 24 hours as well as lower water consumption.

This project meshes perfectly with our own vision of a world where CO2 means green and sustainability is an engine for growth

It is believed that Solidia’s patented process of curing concrete with CO2 instead of water will allow the entire industrial chain to reduce the environmental footprint of pre-cast concrete by up to 70%.

Under the terms of the agreement, of which financial details were not disclosed, Air Liquide will supply all necessary equipment for the project as well as serving as the worldwide preferred provider of CO2 for use within the patented process.

Tom Schuler, President and CEO of Solidia Technologies, praised the partnership and stated, “At this critical stage as we enter the market, Air Liquide’s expertise in gas delivery and equipment engineering enables rapid commercialisation. This project meshes perfectly with our own vision of a world where CO2 means green and sustainability is an engine for growth.”

CO2-cured Solidia Concrete products will be widely available and on sale across both North America and Europe in the coming months.
