Eni, through its CCUS Holding joint venture with Global Infrastructure Partners, has completed installation of the Douglas CCS platform in Liverpool Bay. The platform will act as the offshore hub for the HyNet cluster, collecting CO2 from industrial sites in northwest England and North Wales and sending it through repurposed pipelines to depleted gas reservoirs under the seabed. The company says it is the first purpose-built offshore platform dedicated to CCS for industrial decarbonization. The project combines 1,885 tonnes of topsides, a 1,755-tonne jacket, and 730 tonnes of foundation piles. Eni says the wider Liverpool Bay CCS network is about 50% complete, with 149 km of existing pipelines being repurposed and 35 km of new pipelines being built. First-phase storage capacity is 4.5 million tonnes of CO2 per year, with potential to reach 10 million tonnes in the 2030s. Construction is expected to start this year, with planned startup in 2028.

This is the kind of CCS news worth watching. Douglas platform is in place and HyNet is moving toward actual injection. The 4.5 Mt per year first phase is real industrial scale. Curious how much of the captured CO2 actually ends up stored versus plans. Article says 50% network complete, so timeline matters.

Good to see installation done, but the hard part is proving the whole chain works: capture at cement and waste plants, compression, pipeline flow, injection into depleted reservoirs. 2028 start-up gives time to test. Anyone know how the repurposed pipelines handle CO2 spec, especially water content? That tends to be where projects hit snags.

Useful detail: 60% of capex via UK supply chains. That is the kind of local content number worth tracking. But the bigger test is whether HyNet emitters actually connect and pay. CCS clusters only work if industrial users can't just send CO2 elsewhere. Need binding offtake or penalty to make storage demand real.

Impressive logistics, but I want to see operating cost per tonne once it runs. Purpose-built offshore platform plus 149 km of repurposed pipelines and 35 km new ones. That is heavy fixed infrastructure. At 4.5 Mt a year it can work, but payback depends on carbon price and emitter uptake. The 200-300 long-term jobs over 25 years is modest.
