\u201cRenewable diesel is generally a hydrocarbon and is indistinguishable from the petroleum it is replacing. So, it is basically diesel fuel from a renewable resource,\u201d explained Michael Lokey, executive officer for Sunshine Biofuels.<\/p>\n
Getting a little more technical, renewable diesel is a hydrocarbon diesel fuel produced by hydroprocessing of fats, vegetable oils, and waste cooking oils.<\/p>\n
\u201cIt has very similar properties to petroleum-derived ultra-low sulfur diesel (ULSD) and must meet the same ASTM standard as petroleum-derived diesel,\u201d said Robert McCormick, senior research fellow for the National Renewable Energy Laboratory (NREL).<\/p>\n
Renewable Diesel 101<\/h2>\n
Renewable diesel is a next-generation synthetic diesel fuel.<\/p>\n
\u201cIt can be made from vegetable oil or other biomass feedstock (wood, agricultural waste, garbage, etc.). It can also be made from coal and natural gas, though the status of those products being called \u2018renewable\u2019 is probably not going to happen,\u201d noted Mark Fitz, president of Star Oilco.<\/p>\n
Additionally, this high-quality diesel delivers up to 80% lower lifecycle emissions compared to petroleum diesel.<\/p>\n
\u201cUnlike biodiesel, Neste MY renewable diesel is a direct replacement fuel that requires no blending and is compatible with all diesel engines. In fact, every molecule in Neste MY renewable diesel is found in ULSD diesel, meaning no change in infrastructure is required to switch,\u201d according to Matt Leuck, technical manager, North America for Neste US.<\/p>\n
The processes making renewable diesel are usually either Fischer-Tropsch or Hydrogenation.<\/p>\n
\u201cThese processes take one molecule, crack it into baser parts, and then reform it with the introduction of hydrogen into a super clean, high-performance synthetic hydrocarbon molecule,\u201d Fitz said. \u201cBasically, renewable diesel producers use processes that are pretty much magic. They take low-grade rendering and veggie oils and remake it into pure diesel fuel.\u201d<\/p>\n
There are also a few processes that make renewable diesel additives.<\/p>\n
\u201cThese renewable diesel fuels do not have the exact chemical structure of diesel fuel but can be blended with traditional diesel fuel without affecting the specification of the fuel. The simplest way to describe it is a fungible diesel product made from sustainable sources. But, it is not made with transesterification, which is what biodiesel uses for production. To make it even easier, renewable diesel is fuel made from renewable resources that can replace all or some diesel in the transportation market that is not biodiesel or made via transesterification,\u201d said Lokey of Sunshine Biofuels.<\/p>\n
Due to the purity of the process renewable diesel is a purer fuel, therefore performs better, with a lower CO2 footprint and better tailpipe emissions than petroleum diesel.<\/p>\n
\u201cIt\u2019s an amazing product that says huge things about how bright the future of humanity is. This is the fuel of the future. A low carbon renewable better performing fuel.\u201d<\/p>\n
Benefits of Renewable Diesel<\/h2>\n
One thing for fleets to keep in mind, however, is that this is not biodiesel, it is a premium fuel that does come with a premium price tag, costing more than petroleum and diesel, currently.<\/p>\n
But, a few of the benefits of renewable diesel over biodiesel or traditional diesel fuel help outweigh the price premium. These benefits include better vehicle performance, reduced maintenance, cleaner burning, and no odor.<\/p>\n
\u201cRenewable diesel is an advanced biofuel, meaning it provided greater than 50% lifecycle greenhouse gas (GHG) emissions-reduction relative to petroleum-derived diesel,\u201d explained McCormick of NREL.<\/p>\n
Several experts noted the cleaner-burning properties of the fuel.<\/p>\n
\u201cIt is a cleaner burning low CO2 fuel with a better performance characteristic seen in more power, fewer regens in DPFs, and many fleets state they see better mileage,\u201d said Fitz of Star Oilco.<\/p>\n
An added benefit is related to fuel storage.<\/p>\n
\u201cRenewable diesel can be stored for a long time with no deterioration in quality or water accumulation, which can promote microbial growth,\u201d according to Leuck of Neste US.<\/p>\n
Its similarity to petroleum-derived diesel means there are no infrastructure or vehicle compatibility issues. Renewable diesel can be blended with conventional diesel at any level.<\/p>\n
Additionally, there is little to no odor.<\/p>\n
\u201cUnlike other diesel fuels, renewable diesel contains no aromatics or impurities, producing no odor and allowing fuel to combust with maximum efficiency while decreasing the frequency of injector maintenance and diesel particulate filter regenerations. Plus, no odor means it\u2019s less harmful for drivers, handlers and the environment. Drivers won\u2019t be inhaling harmful fumes all day or going home smelling like diesel,\u201d according to Leuck of Neste US.<\/p>\n
Renewable diesel also experiences improved performance in cold weather, featuring a low \u201ccloud point\u201d for superior cold-weather performance and a high cetane number that ensures quicker cold starts, less noise, and better throttle response.<\/p>\n
Particular to the work truck industry, one of the main benefits is the fact that renewable diesel is a direct replacement fuel that can be used in existing heavy-duty diesel engines without any modification.<\/p>\n
\u201cSince it is hydrogenated, it doesn\u2019t contain oxygen, meaning fleets are not faced with any cold weather, water attraction, or storage challenges,\u201d according to Leuck of Neste US. \u201cOur renewable diesel can also significantly reduce a work truck fleet\u2019s carbon footprint.\u201d<\/p>\n
Finally, fleets focused on total uptime or experiencing recurring injector and DPF maintenance issues should see improvement in the use of renewable diesel.<\/p>\n
\u201cIt is a cleaner, drier, and superior performing fuel to wholesale ASTM diesel. Fleets with a high amount of idling and stop and go will particularly benefit. Fleets, such as utility bucket trucks or garbage haulers, report renewable diesel is described to significantly reduce the maintenance cost of a modern clean diesel truck,\u201d Fitz said.<\/p>\n
Availability & Future Growth<\/h2>\n
In the U.S., nearly 7 billion metric tons of GHG are emitted each year and more than 28% come directly from the transportation industry.<\/p>\n
\u201cDiesel emissions have been reduced by nearly 95% since the implementation of Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR), but recently the federal government imposed further regulations to tighten emissions and improve the fuel economy for heavy-duty trucks by up to 25% from now through 2027,\u201d said Leuck of Neste US. \u201cGlobal demand for cleaner fuels is constantly growing and more and more companies around the world are investing in renewable diesel technology.\u201d<\/p>\n
Right now, renewable diesel fuel is not widely available, mainly used in the west coast states of Washington, Oregon, and California. But, plants are under construction and the demand and need for this cleaner-burning fuel is present.<\/p>\n
\u201cQuite a few plants are currently under construction and we expect traditional refiners to also start producing this fuel. \u00a0Still, as the largest producer in the U.S., the Renewable Energy Group describes this extra capacity is \u2018like water in a desert\u2019 as supply is so short of demand currently,\u201d Fitz noted.<\/p>\n
Lokey of Sunshine Biofuels believes that renewable diesel will eventually replace biodiesel.<\/p>\n
\u201cIt is a much easier and more beneficial product for the petroleum supply chain and technology to process it from lower cost feedstocks or renewable sources are developing that make it more cost competitive than other solutions,\u201d Lokey said.<\/p>\n
And, while domestic production is increasing, McCormick of NREL noted that for it to become much more widespread will require the development of a much larger resource of fats and oils feedstocks.<\/p>\n
