Technip Energies and Mitsui OSK line up for ground-breaking offshore CCS hub

France-headquartered Technip Energies and Mitsui OSK Lines of Japan are in the frame for a key contract for a planned carbon dioxide floating storage and injection hub facility offshore Australia.

A letter of intent covering engineering, procurement and construction and operation of the facility was issued by Perth-based CCS developer deepC Store (dCS) in relation to what is being called the CStore1 project.

Developer dCS is hailing the CStore1 project as the first ever large-scale offshore multi-user hub.

The offshore facility has a planned CO2 injection capacity of between 1.5 million and 7.5 million tonnes per annum.

The project, which purports to cover the entire carbon capture and storage value chain, involves the capture and liquefication of CO2 from industrial sources in Australia and potentially also within the wider Asia-Pacific region.

Liquid CO2 will be shipped to the floating storage and injection hub offshore northern/western Australia where it will be temporarily stored before injection for permanent subsurface storage near the hub.

“The FSI Hub is a key facility within the overall CStore1 project for unlocking a range of remote offshore CO2 injection sites,” said dCS chairman Jack Sato, who added that the letter of intent with Mitsui OSK and Technip Energies “ensures technical confidence to develop Cstore1 as the first offshore floating CCS hub project in [the] Asia Pacific region”.

C-Hub technology

Technip Energies will provide front-end engineering and design and EPC services for the hub using its C-Hub proprietary technology, while Mitsui OSK will deliver pre-FEED for the CO2 shipping and collaborate closely with dCS and Technip Energies on the hub facility.

Technip Energies’ wholly owned subsidiary Genesis will support delivery of the hub by engineering the subsea umbilicals, risers and flowlines equipment, including architecture selection, flow assurance, engineering for risers and flowlines, and christmas trees.

“We look forward to creating a cost effective and sustainable option for the receiving and handling of carbon in the [Australian] region,” Technip Energies’ Australia country manager Paul Browne said.
