Shipboard Carbon Capture: GCMD's "Dead End" Report They Didn't Want You to Read!

TL;DR: A major report on shipboard carbon capture quietly revealed it's a climate dead end, with almost no real-world emissions reductions. It's like trying to bail out the Titanic with a thimble, honey, and they still want to call it a "viable option."

Meta: A GCMD report on shipboard carbon capture implicitly shows the tech is not viable, yielding minimal GHG reductions despite optimistic framing.

Alright, alright, gather 'round, 'cause Uncle Eddie's got a story about some folks trying to clean up the oceans, but they ended up just cleaning up their press release! The Global Centre for Maritime Decarbonisation (GCMD) just dropped a report, Project CAPTURED, on shipboard carbon capture, and if you read past the shiny headlines, it's basically screaming, "This ain't it, chief!" They spun it like a win, but the data, honey, the data don't lie. It's like trying to put lipstick on a pig that's already sunk to the bottom of the sea.

This wasn't some theoretical mumbo jumbo either; this was a real pilot on a real ship. They slapped an onboard capture system on a vessel burning low-sulfur fuel. Guess what their gross capture rate was? A measly 10.7%. That's like trying to catch all the rain in a hurricane with a tiny teacup! And after you factor in all the energy penalties, the losses, the venting, the long-haul transport, and the processing of that captured CO2, the net greenhouse gas reduction was a pathetic 7.9%. Seven point nine percent! That's approaching homeopathic levels of climate action, folks. Without downstream credits for displacing other materials, the whole darn value chain doesn't even break even. It increases emissions! They called this "significant emissions savings potential." I call that a stretch bigger than my last pay-per-view special!

Physics Don't Negotiate, Baby!

The report tries to be optimistic, talking about "extrapolating to higher capture rates," but the physics, honey, the physics are a stone-cold killer. When you burn fossil fuel, the CO2 you get is three times the mass of the original fuel. And the volume of that liquefied CO2? Four times the volume of the fuel! You gotta store that on a ship! That means bigger tanks, structural redesigns, and less room for actual cargo. That ain't a minor tweak; that's a whole new boat!

And capturing, compressing, and liquefying that CO2 sucks up energy like a vampire at a blood bank. The pilot showed a 5-6% fuel penalty just for the capture and conditioning. That means you're burning more fuel to capture some of your emissions, which is like trying to lose weight by eating more, but only salad. Plus, you can't even empty the tanks completely – about 28% of the captured CO2 remained in the tanks in the pilot. That's a lot of leftovers that you still gotta carry! These aren't glitches; these are the laws of the universe, and they are not here for your decarbonization dreams, at least not with this method.

The Logistical Nightmare and What's Actually Working

Then there's the logistics. After capturing this tiny bit of CO2, they trucked it 2,200 km to a utilization facility. The transport emissions alone erased much of the capture benefit. Ports ain't got CO2 pipelines, storage hubs, or sequestration sites just magically popping up. This ain't "Field of Dreams" where if you build it, they will come. This is a massive, expensive, infrastructure-heavy waste management problem that yields almost no climate benefit. Meanwhile, simpler, more effective solutions are already sailing the seas. Inland and short-sea shipping is going electric, baby! Swappable batteries, fully electric ro-ro vessels – they're delivering 90-100% reductions, no goofy waste streams involved. They're using ports that already handle electricity, not building entire new CO2 pipelines.

So, what's the deal with GCMD's rosy spin? The report itself is transparent with the numbers, but the executive summary and press release paint a picture of "potential" where the evidence points to a sunken ship. It's time for these organizations to be clear: when a pathway delivers single-digit net reductions and relies on accounting tricks, it's a dead end. We need to stop chasing ghosts and invest in what actually works. The data is screaming at them, but they got their fingers in their ears!

What’s Next

This report, despite its optimistic framing, should serve as a stark warning to the maritime industry and policymakers. Expect increased scrutiny on "bridge" technologies that don't deliver meaningful emissions reductions. The focus will likely shift more aggressively towards truly transformative solutions like sustainable biofuels, electrification for shorter routes, and potentially green hydrogen or ammonia if their upstream emissions can be massively decarbonized. Clarity and honesty about technological viability are crucial to avoid wasting precious time and resources on dead ends.

Sometimes, the hardest truth is the one that sets you free... from bad ideas!
