A new study by the International Council on Clean Transportation (ICCT) estimates heavy fuel oil (HFO) use, HFO carriage, the use and carriage of other fuels, black carbon (BC) emissions, and emissions of other air and climate pollutants for the year 2015, with projections to 2020 and 2025.

That study provided estimates of vessel traffic (numbers of vessels and transits) based on modeling of current vessel activity patterns, growth potential, and vessel projection scenarios, including diversion from other routes, and oil and gas development.

The new ICCT study combines global ship operations (AIS) data with detailed vessel characteristics for more than half a million ships to estimate GHG emissions and air pollution from shipping at high resolution (1° x 1°) on an hourly basis for the years 2013 to 2015. —ICCT report. Click to enlarge.
You lose the flexibility of the hybrid being able to fuel up nearly instantaneously at a gas station, and pay an additional $10k for that loss.
