Pathways to Low Carbon Shipping

“I'm very brave generally, he went on in a low voice: only today I happen to have a headache.” -- Lewis Carroll (English Logician, Mathematician, Photographer and Novelist, especially remembered for Alice's Adventures in Wonderland. 1832-1898)

While most of the posts to the Desulfurization Blog are related to desulfurization, I wander a bit.  Hence the document below, which intrigued me.

Pathways to Low Carbon Shipping - Abatement Potential Towards 2050
DNV - Det Norske Veritas
Summary
In 2009, DNV published Pathways to Low Carbon Shipping that demonstrated a cost-effective potential for reducing CO2 emissions by 15 % on the existing world shipping fleet and by 30 % on of the predicted global fleet in 2030. In this latest study, DNV has used a new probabilistic model to analyse pathways towards 2050.
In addition to those measures analysed in the 2009 study, the potential uptake of a wide range of alternative fuels is modelled. The results demonstrate that with uptake of operational and technical measures, as well as biofuels and LNG, the cost-effective CO2 reduction potential in 2050 is around 50 % of baseline emissions, indicating stabilisation of emissions from world shipping at present levels.
The results show LNG could be important part of the fuel mix in 2050 based on cost-effectiveness considerations. However, this study shows that for shipping to provide a substantial contribution to a 2°C pathway, a regulatory or financial incentive for biofuel is one alterative, but that nuclear power in large ships could also cut emissions drastically in a cost-effective way.

How I found it:
I subscribe to Diesel & Gas Turbine Worldwide (http://dieselpub.com/), which offers free subscriptions to those who qualify.  A recent email alerted me to an article describing the DNV Pathways publication.

I then Googled® Pathways to Low Carbon Shipping, which led me to the full text document.

Incidentally, if you Google® Jean Steinhardt, you will find a number of interesting items.
