The state of Minnesota will implement a new biodiesel standard next spring, as Minnesota moves to a 20% biodiesel blend (B20) at pumps across the state. This new standard builds on Minnesota’s national leadership—in 2005, Minnesota became the first state in the nation to require all diesel fuel to have a blend of at least 2% biodiesel (B2).
Beginning in May 2018, B20 will be sold at filling stations across Minnesota during summer months, when higher biodiesel blends can be used reliably. In October, the biodiesel blend will drop back to B5 to ensure cold-weather reliability. Beginning in 2019, B20 will be available from April through September every year.
A large portion of Minnesota’s biodiesel is made from homegrown soybeans, which are one of the state’s leading cash crops. The Minnesota biodiesel industry annually contributes more than $1.7 billion to the economy. The state currently has three biodiesel plants located in Albert Lea, Brewster and Isanti, which combined, produce about 74 million gallons of biodiesel annually.
According to the American Lung Association in Minnesota, the use of biodiesel significantly reduces tail pipe emissions. B20 is expected to reduce 130 tons of particulate emissions and approximately 1 million tons of CO₂ next year.
