Renewable Diesel Vs Biodiesel

If you are comparing renewable diesel vs biodiesel, you should understand the difference between the two fuels. There are a number of key factors to consider, including cost, storage conditions, and environmental impact. Here is a brief overview of the main differences between the two fuels.


When it comes to fueling your car, deciding between renewable diesel and biodiesel can be an important decision. Both fuels are made using similar processes, but there are differences between them. For instance, renewable diesel is cleaner than biodiesel, but it is also more expensive. Whether you should use renewable diesel or biodiesel depends on the type of engine you have and the fuel you intend to use.

The renewable diesel fuel you buy can be derived from a variety of sources, such as vegetable oils and wastes. The process also allows you to make use of waste byproducts from your business, which is great for the environment. Biodiesel and renewable diesel can also be blended together to meet the requirements of different end users and refiners.

While renewable diesel and biodiesel are similar in many ways, the main differences between them can be found in the production process. Biodiesel uses feedstock that is treated with methanol, which creates fatty acid methyl esters. Renewable diesel uses a different process, which involves using hydrotreated vegetable oil. Hydrotreating removes compounds with nitrogen and oxygen.

Using renewable diesel for your vehicle is beneficial to the environment, particularly if you drive in cold climates. It is compatible with most modern diesel engines and does not require engine modifications. It also has high cetane numbers, which make it a good choice for drivers in cold climates. Additionally, renewable diesel is compatible with existing diesel distribution infrastructure. It also does not require special tanks or storage facilities.

Both biodiesel and renewable diesel have their advantages and disadvantages. Biodiesel is a more expensive fuel, and is not compatible with all vehicles. It is more environmentally friendly than renewable diesel, but it cannot replace gasoline for your vehicle. However, it is the best option for drivers who want to reduce their carbon footprint. However, you need to be careful about the type of biodiesel you choose for your car.

Biodiesel offers better performance than petrodiesel. Its higher cetane rating and added lubricity will make your engine run smoother and less frequently. This also means that biodiesel won't wear down your engine as much. You can also blend biodiesel with petrodiesel to increase the lubricity of the fuel.


In comparing costs of renewable diesel vs biodieses, it is important to consider the carbon intensity of the fuel. The carbon intensity of renewable diesel is high because of the high cost of refining it and transporting it. However, electricity that powers electric vehicles (EVs) is low, and the carbon intensity is estimated to be 83 gCO2e/MJ by 2020, assuming that the grid mix is clean.

Both biodiesel and renewable diesel fuel are produced from oil fats. While both are clean, they differ in the ways that they affect the environment. Biodiesel can be affected by oxygen, which can cause it to freeze during storage. This can lead to algae growth and increased emissions.

The cost of renewable diesel varies widely from state to state. The price for renewable diesel in California is close to petroleum diesel, while it is about a dollar higher in Oregon. This is partially due to the value of carbon credits associated with the fuel. However, this price difference should decrease as more renewable diesel capacity is put online.

Renewable diesel is produced from sustainable feedstocks. While biofuels produced from waste oil are generally higher in price, those produced from virgin oil crop feedstocks are cheaper. The difference in price can be up to $500 per metric ton. The higher cost of renewable diesel can also be offset by incentives offered by the federal government.

Renewable diesel is considered to be more environmentally friendly than petroleum diesel, and is compatible with existing diesel engines. It has also been shown to reduce greenhouse gases, resulting in cleaner air in trafficked areas. Some countries have also incentivized the use of renewable diesel in vehicles. While it costs more than petroleum diesel, its lower production cost is offset by incentives.

In the United States, renewable diesel is cheaper than biodiesel. However, the supply of renewable diesel is limited and is hard to come by outside of the West Coast. In addition, biodiesel is more effective than petroleum diesel in reducing harmful pollutants in tailpipe emissions.

Storage conditions

When storing renewable diesel, you need to keep several things in mind. For one, it's important to store biodiesel at the proper temperature range. If you store biodiesel too warm, it will likely begin to gel, and if it's stored too cold, it will grow mold. Another important consideration is the amount of oxygen in the fuel. Biodiesel should be stored in a cool, dry location away from the sun and heat.

For low-use biodiesel, a higher oxidation reserve is required to ensure its long-term stability. For this, ASTM specifications for biodiesel blends and B100 include guidance for monitoring stability. It is important to periodically measure particulate matter and acidity to ensure that the fuel is stable.

Compared to biodiesel, renewable diesel is much cleaner and produces fewer harmful emissions. The hydroprocessing process removes the impurities and aromatic compounds, which make it odorless and less harmful to the environment. Additionally, it burns cleaner than biodiesel, which makes it an excellent choice for vehicles.

For long-term storage, it's crucial to maintain a clean tank. This prevents water from contaminating the fuel. Water can also promote corrosion and microbial growth, which compromises the fuel's quality. Water also tends to accumulate in biodiesel, which can make it unstable over a period of months.

While both are considered green fuels, the production process for biodiesel is similar to petroleum diesel. Both fuels are hydrocarbons, but the biodiesel process is less capital-intensive. In addition, the renewable diesel process uses an esther, which can cause problems in some motor engines. It can cause problems in the engine when too concentrated, and it can cause damage to parts of the fuel system. Additionally, it can also absorb water, leading to microbial growth in the fuel tank.

Biodiesel can be used in vehicles, but it is not a suitable replacement for petroleum diesel. The storage conditions for both are different, so it's essential to decide on a storage option based on your specific circumstances. The main concern with biodiesel is that it may need to be stored for a long period of time. In addition, biodiesel might require siphoning out fuel and adding a fuel stabilizer. It's important to remember that biodiesel is more environmentally-friendly than petrodiesel.

Environmental impact

Renewable diesel has a lower carbon footprint than biodiesel, and it can be used to fuel a vehicle more efficiently. It can also be a more affordable fuel, with petroleum producers subsidizing its production through the Low Carbon Fuel Standard, resulting in lower prices for consumers. But renewable diesel can also have a higher carbon intensity, depending on the process used to produce it. This carbon intensity is expected to rise in the future, since the production of renewable diesel is expected to keep on increasing until there are no more low-carbon feedstocks available.

Exposure assessment studies for renewable diesel and biodiesel use can take advantage of well-established environmental air monitoring and industrial hygiene methods. These methods have been developed by regulatory agencies and are easy to adapt for use in the field. A well-known one is Method 5040 from the National Institute of Occupational Safety and Health. These studies measure concentrations of pollutants in the air near the work area and around the worker's breathing zone.

The environmental impact of biodiesel depends on the process used to make it. The process involves combining fatty acid esters from plant materials with an alcohol. This process, known as transesterification, produces fatty acid methyl esters, which are hydrocarbons that are used as fuel for engines. Biodiesel is generally cleaner than petrodiesel, but the process is not without disadvantages.

In addition to the environmental benefits of biodiesel, the fuel also has health benefits. Research studies on biodiesel emissions have found that it improves air quality and reduces air pollution. However, these studies have not looked into the long-term effects of biodiesel on human health. Fortunately, the fuel has been gaining popularity due to its lower cost and environmental benefits.

As the demand for biofuels rises, large producers of biofuels are increasing their production facilities. Most of these plants are focused on producing renewable diesel, though there are some plants under construction to produce SAF as well.
