B&W Wins Engineering Study for Alberta Air-Storage and Hydrogen Hub
- Babcock & Wilcox was awarded a contract by Cache Power Corp. to execute an engineering study for Cache Power's Marguerite Lake Compressed Air Energy Storage (CAES) and Hydrogen Hub Project near La Corey, Alberta, announced on 28 October 2025[1][4].
- The study is partly funded by an Alberta Innovates grant; the funder lists $2,000,000 of its money against a total project budget of C$4,252,167 running from March 2025 to March 2026, with Cold Lake First Nations as a partner[1][2].
- Cache Power is building the 640 MW CAES plant next to the existing Marguerite Lake substation in two identical 320 MW phases, storing grid electricity as compressed air in mined salt caverns[1][4].
- B&W's BrightLoop chemical-looping process would make up to 60 tonnes a day of hydrogen to reheat the air, while producing a nearly pure CO2 stream for capture and storage so the plant can reach net-zero emissions[1][4].
- Each phase stores 15,360 MWh (48 hours), 30,720 MWh at full build, and the site sits directly above the Lotsberg Salt formation[3][4].
- The funded work is meant to validate large-scale hydrogen production and storage and support a final investment decision on the hub[2].

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
