Minnesota was the first US state to mandate the use of biodiesel, and currently requires a 20% biodiesel blend (B20) during the summer months, and 5% (B5) for the rest of the year. Biodiesel is a clean-burning, locally-grown fuel, produced from renewable sources such as soybean oil, corn oil, or waste oil. It helps to reduce the use of petroleum diesel, and brings Minnesota closer to energy independence. The state offers grants to biofuel producers, and biodiesel supports 62,000 jobs in the US.

Biodiesel blends
Minnesota was the first US state to require the use of biodiesel. From April to September, diesel fuel sold in the state must contain at least 20% biodiesel (B20), while for the rest of the year, it must contain at least 5% biodiesel (B5). During the transition period from winter to spring (April 1 to April 14), a lower blend than B20 but not less than 10% biodiesel (B10) is allowed.
In the US, biodiesel consumption and production have increased significantly since the early 2000s due to government incentives and requirements. As of 2022, biodiesel accounted for about 9% of total US biofuels production and consumption, with a production capacity of about 2.9 billion gallons per year. Most US biodiesel is consumed in blends with petroleum diesel, with B20 being the most common blend.

Biodiesel laws
Minnesota is one of the leading states in the United States when it comes to the adoption of biodiesel fuels. The state has a number of laws and incentives in place to promote the use of biodiesel, which is a renewable, clean-burning fuel made from a variety of sources, including vegetable oils, animal fats, and recycled restaurant grease.
The Minnesota Biodiesel Mandate, also known as the B20 Blend Mandate, is a key piece of legislation that requires all diesel fuel sold in the state during the summer months (April to September) to contain a blend of 20% biodiesel (B20). This mandate was first introduced in 2008, with an initial requirement of a 5% biodiesel blend (B5), and has since been gradually increased to B20. The mandate is an important driver of biodiesel use in the state, ensuring that a significant portion of the state's diesel fuel supply is replaced with a cleaner, more sustainable alternative.
Additionally, Minnesota has a You may want to see also Minnesota was the first state to mandate the use of biodiesel, and currently has a 20% biodiesel blend (B20) standard during the summer months (April to September). The Minnesota Department of Agriculture, Department of Commerce, and the Pollution Control Agency must submit annual reports on the implementation of minimum biodiesel content requirements, including price and supply data. The Minnesota Department of Weights and Measures promotes the replacement of petroleum with biofuels, with a goal for biofuels to account for a specified percentage of all gasoline offered for sale. Each state department or agency must prepare a biennial sustainability plan that includes strategies to modify vehicle use practices and prioritize the purchase of vehicles that use alternative fuels. The Minnesota Department of Agriculture provides grants and incentives to biofuel producers and advanced biofuel production facilities. The Advanced Biofuel Bioincentive Program offers reimbursements of $2.1053 per million British Thermal Unit (MMbtu) for advanced biofuel produced from cellulosic biomass and $1.053 per MMbtu for advanced biofuel produced from sugar or starch feedstocks. To be eligible, facilities must source 80% of their feedstocks from Minnesota and meet certain production levels and deadlines. Biodiesel blends in Minnesota must comply with ASTM Standard D7467-10, and biodiesel produced from palm oil is not considered biodiesel fuel unless it is waste oil or grease collected within the US or Canada. Gasoline sold in Minnesota must contain a minimum of 10% corn-based ethanol by volume or an equivalent biofuel as authorized by the EPA. You may want to see also

Minnesota was the first US state to require the use of biodiesel. During the summer months of April through September, diesel fuel sold in the state must contain at least 20% biodiesel (B20). For the rest of the year, from October to March, diesel fuel must contain at least 5% biodiesel (B5). Biodiesel is a renewable, biodegradable, mono-alkyl ester combustible liquid fuel derived from agricultural plant oils or animal fats. It can be produced from vegetable oils, yellow grease, used cooking oils, or animal fats. The production process involves transesterification, which converts fats and oils into biodiesel and glycerin (a coproduct). Approximately 100 pounds of oil or fat are reacted with 10 pounds of a short-chain alcohol (usually methanol) in the presence of a catalyst (usually sodium hydroxide or potassium hydroxide) to form 100 pounds of biodiesel and 10 pounds of glycerin. This coproduct, glycerin, is a sugar commonly used in pharmaceuticals and cosmetics. There are some important safety considerations when making biodiesel. Heating the oil to remove water and transferring the heated oil are two potentially dangerous steps. When heating oil, it is important to keep it from spattering and making the floor slippery. It is also crucial to avoid using burners or electric heaters. Hot oil can melt plastic buckets, so it should be cooled before being poured into a plastic container. Additionally, the area should be well-ventilated to reduce the risk of fire and explosion due to methanol vapors. The cost of biodiesel production includes the initial cost of processing equipment, chemicals, gas or electricity, and labor. Feedstocks can vary in cost depending on the producer's location and operation, ranging from new food-grade cooking oil to waste oil obtained for free from local restaurants. Methanol costs have been volatile, typically costing around 25% more than the current pump price for gasoline. Catalyst costs start at approximately $2.50 per pound, with sodium hydroxide being the least expensive option. The state of Minnesota provides incentives for biodiesel production, with the Minnesota Department of Agriculture offering grants to biofuel producers. Additionally, state agency plans encourage the use of alternative fuels and increase the use of renewable fuels derived from agricultural or waste products. You may want to see also Minnesota was the first state to require the use of biodiesel, and currently mandates a minimum biodiesel blend in diesel fuel sold in the state. From April to September, this minimum is 20% biodiesel (B20), and for the rest of the year, it is 5% biodiesel (B5). Biodiesel is a renewable and biodegradable fuel derived from agricultural plant oils or animal fats. It is created by chemically reacting fatty acids and alcohol—usually, this means combining vegetable oil with methanol in the presence of a catalyst like sodium hydroxide. Biodiesel is a better engine fuel than pure vegetable oil due to its lower viscosity. Biodiesel blends of 20% or greater are considered alternative fuels by the Minnesota Department of Weights and Measures. B20 is a common blend as it balances cost, emissions, cold-weather performance, and compatibility with conventional engines. Engines running on B20 have similar fuel consumption, horsepower, and torque to engines running on petroleum diesel. While B20 has slightly less energy per gallon, users generally report no noticeable difference in performance or fuel economy. Biodiesel has emissions benefits over conventional diesel, particularly for engines manufactured before 2010. Engines with selective catalytic reduction (SCR) systems have the same air quality benefits whether running on biodiesel or petroleum diesel. However, biodiesel has greater greenhouse gas emissions benefits. The emissions benefit is roughly proportional to the blend level. For example, B20 would provide 20% of the emissions reduction benefit of pure biodiesel (B100). However, high-level biodiesel blends like B100 are less commonly used as transportation fuel due to a lack of regulatory incentives and pricing. There are concerns about the effects of biodiesel on engines, including reduced performance, damage to components, and engine failures. Some manufacturers are wary of honouring warranties if biodiesel is used. However, other manufacturers encourage biodiesel use, and careful research and controlled studies have provided reliable guidance on biodiesel performance. Good-quality biodiesel generally performs well in engines. Biodiesel has higher oxygen content and lacks aromatic compounds and sulfur, resulting in less air pollution. The exception is nitrogen oxide (NOx) emissions, which are slightly higher but can be minimised through proper engine tuning. Like petroleum diesel, biodiesel experiences issues in cold weather due to clogging of filters and coking of injectors. However, flow-improving additives and "winter blends" with kerosene can mitigate these problems. Pure biodiesel operates well down to about 5°C, depending on the oil type. You may want to see also Yes, Minnesota uses biodiesel. In 2002, the Minnesota state legislature passed a law requiring diesel fuel sold in the state to contain at least 2% biodiesel. This law came into effect on September 29, 2005. From April 15 to September 30, diesel fuel in Minnesota must contain 20% biodiesel (B20). From October to March, diesel must contain at least 5% biodiesel (B5). From April 1 to April 14, diesel can be a lower blend but must contain at least 10% biodiesel (B10). Biodiesel is a clean-burning, locally grown fuel that helps boost Minnesota's farm economy and reduces dependence on fossil fuels. It also brings Minnesota closer to energy independence and reduces greenhouse gas emissions. Biodiesel in Minnesota is primarily made from soybean oil, but it can also be produced from corn oil, waste oil, and used cooking oils.Understanding Diesel Generator Fuel Consumption Rates
