US: OGCI Climate Investments has made in an investment in Solidia Technologies to support the adoption of Solidia’s patented cement and concrete technology using CO2.
The Oil and Gas Climate Initiative (OGCI) is a chief executive officer (CEO) led initiative of 10 oil and gas companies that collaborate on action to lead the industry response to climate change. OGCI Climate Investments, its investment arm, supports the development, deployment and scale up of new technologies that are intended to reduce greenhouse gas emissions.
“We believe that Solidia Technologies’ product and process can provide a step change in lowering the greenhouse gas and water footprint of the cement and concrete industry,” said OGCI Climate Investments CEO Pratima Rangarajan.
Solidia Cement is a non-hydraulic cement composed primarily of low-lime-containing calcium silicate phases, such as wollastonite and pseudowollastonite (CaO·SiO2) and rankinite (3CaO·2SiO2). The setting and hardening characteristics of Solidia Cement are derived from a reaction between CO2 and the calcium silicates. The company uses a patented process called reactive hydrothermal liquid phase densification (rHLPD) to do this. Solidia Cement is intended to be a sustainable replacement for Ordinary Portland Cement (OPC). It uses the same manufacturing process, equipment and raw materials used by the cement industry while consuming less energy and generating less greenhouse gases.
