Pieridae Energy Ltd. plans to develop a 3-million tonne/year (tpy) carbon sequestration project, Caroline Carbon Capture Power Complex, in conjunction with its Goldboro LNG project. The complex, sited at Pieridae’s Caroline gas processing plant in Alberta, will be a combination of large-scale carbon capture and sequestration and powerplant.

Carbon capture will pull from three sources: CO2 generated by the gas processing plant, from power production, and produced by third parties. It will be stored in one of Caroline’s depleted gas reservoirs in an amount equal to Goldboro’s anticipated emissions.

The complex will produce as much 800 Mw/year of electricity. Phase 1 will sequester 1 million tpy and produce about 200 Mw/year.

Caroline can process 300 MMcfd of sour gas and includes 4,100 tonnes/day of sulfur forming and storage and two compressor stations. Gas processed at Caroline and two other nearby plants will be used to feed Goldboro LNG. The three plants combined can process as much as 750 MMcfd but have been operating at 330 MMcfd (OGJ Online, Dec. 8, 2020).
