Royal Caribbean to use LNG and fuel cells on ships to reduce emissions

Luxury cruises are increasingly popular but can come with huge environmental costs around ports and whilst at sea, due to sulfur and other harmful particulates from the heavy fuel oil burnt by most ships. Royal Caribbean is aiming to reduce such emissions from future cruise liners through a combination of liquefied natural gas and fuel cells from the early 2020’s.

Research shows potential for turning CO2 to stone

The BBC reports on a promising new method for storing CO2, tested by researchers in Iceland. From the article:

The researchers report an experiment in Iceland where they have pumped CO2 and water underground into volcanic rock.

Reactions with the minerals in the deep basalts convert the carbon dioxide to a stable, immobile chalky solid.

Even more encouraging, the team writes in Science magazine, is the speed at which this process occurs: on the order of months.
