Factbox-Proposed capital projects relying on Alberta carbon capture and storage build-out

CALGARY, Alberta (Reuters) - The Canadian province of Alberta is growing its carbon capture and storage (CCS) industry, and in late March picked proposals for six open-access sequestration hubs in the Edmonton region.

The province has attracted a slew of proposals for low-emissions industrial projects over the last year, which will rely on CCS to lower emissions.

Below is a round-up of the six storage hubs being developed, and proposed industrial projects that are looking to capture carbon:

PROPOSED STORAGE HUBS

* Enbridge Inc plans to build the Open Access Wabamun Carbon Hub.

* Pembina Pipeline Corp and TransCanada PipeLines Limited, a unit of TC Energy, are proposing the Alberta Carbon Grid.

* Shell Canada is looking at building the Polaris Carbon Sequestration Hub.

* Bison Low Carbon Ventures Inc is looking at building the Meadowbrook Hub Project.

* Wolf Carbon Solutions Inc wants to build the Wolf Carbon Hub.

* Enhance Energy Inc is planning the Origins Project hub.

PROPOSED LOW-EMISSIONS INDUSTRIAL PROJECTS:

* Dow Inc will expand and retrofit its Fort Saskatchewan site to triple production while cutting emissions net-zero emissions, and expects a new ethylene cracker to come online by 2030. Final investment approval still needed from the board.

*Air Products is planning a C$1.3 billion net-zero hydrogen production plant and liquefaction facility expected to come onstream in 2024. The board has approved the project but it is still subject to permit approvals.

* Suncor Energy and ATCO Ltd have proposed a "multi-billion dollar" hydrogen plant producing 300,000 tonnes of hydrogen a year. The companies expect to make a sanctioning decision in 2024. If finalized, project could be operational by 2028.

* Japan's Mitsubishi Corp and Shell Canada have signed an agreement to exploring producing low-carbon hydrogen, aiming for 165,000 tonnes a year in the first phase of the project.

* Japan's Itochu Corp and Petronas Canada are exploring the feasibility of a C$1.3 billion ammonia facility, aiming to produce one million tonnes of ammonia per year.

* Imperial Oil plans to build a renewable diesel facility at its Strathcona refinery using hydrogen produced with carbon capture and storage. It would aim to produce 20,000 barrels, or 3 million litres, per day in 2024.

* Lehigh Cement will add carbon capture to its existing Edmonton plant and has signed a memorandum with Enbridge to store emissions at proposed the Wabamun hub.

* Capital Power Corp is adding carbon capture to its existing Genesee power station, and will store emissions at Wabamun.
