Carbon Capture for ships – current state

Some people think carbon capture onboard is going to be important in meeting emissions goals for ships. There is some entrepreneurship, and some interest by large oil producers and purveyors.

However, many problems remain to be solved. There is essentially no ‘supply chain’ to handle the liquefied carbon product the ships produce onboard from running the carbon capture equipment. Liquid CO2 has a market, but ports are not set up to move it from the ships to storage nor to distribute it into commercial channels.

And it’s not yet clear how much emissions reduction there will be when conventional fuel is burned on ships but the carbon is captured.

Nevertheless, there is activity in this segment. This article explains what’s happening in one case, based on info from classification society DNV.

There are also several links to resources about carbon capture for ship engines.

I’m quite skeptical of carbon capture. It’s nominally a good thing. But the cost of the storage may be large. And how much captured carbon can we reuse?

If the oil companies are back of it, how can it be all good? What are the pitfalls?

US Coast Guard boards MSC ship in ongoing California pipeline spill probe

It is possible that anchor dragging by a ship months ago was responsible for the pipeline spill off Huntingdon Beach CA that appeared just recently.

While it wasn’t a large spill, the sensitive nature of the area requires a full investigation.

Perhaps we will ultimately find out how the spill happened. The investigation will help ordinary folks reflect on the wisdom of allowing pipelines and drilling so close to large populated areas with beautiful, heavily used beaches.

Shipping must review LNG use, as methane’s role in climate change is revealed

It seems polluting gases come from every burned fuel. Now we find that LNG, a fuel that is reputedly cleaner than heavy diesel oil for ships, is likely to create ‘leaked methane’ around the cylinders, allowing it to escape to the open air.

Apparently there are two types of LNG engines: one with ‘tight’ cylinders, and one with ‘loose’ cylinders. The ones with loose cylinders are much cheaper to install, but also leak the methane most. It’s thought that carriers will tend to install the cheaper ones.
