Harvey. Scrubber systems that capture CO2 chemically for disposal on land could be viable, he says, except that they are “likely not scaleable or cost-effective compared to alternatives.”

Separately, debate continues apace over the alternative to installing SOx scrubbers - low sulphur bunker – and whether there will be suf? cient supplies, and just how considerably much more expensive it will be.

Owners may complain, but if it’s an envi- ronmental regulation, it’s not a question of affordability in meeting it, says Ashcroft. “When auto emissions were ? rst put into place, the auto guys said they couldn’t do it. But they have met or exceeded those standards. If there is a rule out there that needs to be done, the shipping industry will require some way of meeting it even if we

Maersk intends to do, starting in 2020 (see related story).

BATTERIES CHARGED

One technology the industry is betting will be huge down the road, is batteries. Needed to store wind and solar energy and to store and power electricity, they are heavy and don’t currently provide enough power in a small enough package to be terribly useful beyond short-sea shipping.
