January 2021—New Global Partners

International collaboration is critically important to successfully address the worldwide need to reduce greenhouse gas emissions, and the STEP Demo project has partners from around the globe to support this capital-intensive demonstration.

In 2020, Engie, a French multinational electric and gas company, Australia's national science research agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), and The Electricity Generating Authority of Thailand (EGAT), their leading state-owned power utility, joined the initiative as Joint Industry Partners. The project team is thrilled to have these world leading organizations as part of the STEP Demo project and their guidance and support to the commercialization of sCO2 power technology.
