Diesel Prices and Maritime Fuel Sulfur Changes

Fuels Institute Review of Literature Summary on IMO2020 (The International Maritime Organization 2020 Sulfur Rule), April 2019

A huge change is coming that is widely talked about in the petroleum industry but not widely known to diesel fuel users in the United States: marine distillate and diesel fuels are expected to move to a lower sulfur diesel. This means far more competition for each gallon of ultra-low sulfur diesel made in the United States. Though marine operators will use a much higher sulfur content than land based fleets, the large reduction in sulfur in this market will increase competition for all lower sulfur diesel fuels.

The Fuels Institute has reviewed literature and available research on potentially large market changes coming for diesel fuel users. By far and away this is a the best source for information we have seen on the subject.

The International Maritime Organizations 2020 Low Sulfur Rule is moving the standard marine fuel to ultra-low sulfur specifications. This change is effective January 1st, 2020 and will affect the entire market for diesel. The presumed big effect is that there will be a much higher cost for the ultra-low sulfur diesel fuel used by on-road industry.

Today the fuel of choice for marine use is typically bunker fuel, a mix of high sulfur distillates (diesel) and other residual fuels that are cheap. According to the Fuel Institute report, the current sulfur content is 2.2% mass/mass. The upcoming IMO2020 Sulfur Rule will drop the expected sulfur content of marine fuels by 77% in order to comply.

There is also a chance that maritime operators will maintain the use of high sulfur fuels and install scrubbers on their ships to clean up the stack emissions coming out of their watercraft.

In order to met this maritime demand, most reports agree that big costs are involved for refiners to upgrade their capacity for this market need. The impact on cost varies but according to the Fuels Institute,”overall, estimates of price impacts to gasoline and diesel range from about 25 cents to 75 cents.” These impacts are limited to a two-to-three year window as the lower sulfur need works its way through the industry.

The world of energy is changing. No doubt those of us watching for it will be ahead of the curve.
