Siemens, TC Energy in Waste-Heat-to-Power Project Feb 12, 2021 6:32:pm Summary by: Dale Lunan Posted in: Siemens, TC Energy in Waste-Heat-to-Power Project Houston-based Siemens Energy said February 12 it had entered into an agreement with Canada’s TC Energy to build a first-of-its-kind waste-heat-to-power facility in Alberta using supercritical carbon dioxide (sCO 2). The facility will capture waste heat from a gas-fired turbine operating at a TC Energy compressor station and convert it into emissions-free power. The electricity produced will be put back into the Alberta power grid, resulting in estimated greenhouse gas (GHG) reductions of 44,000 metric tons/year. Siemens Energy will build, own and operate the facility, with the option for ownership to be transferred back to TC Energy at a later date. It is expected to be commissioned towards the end of 2022.
