Market Challenges And Opportunities
U.S. Biofuels Market- Drivers
- Supportive Government Policies and Incentives: The major driver for U.S. biofuels market growth is supportive federal and state-level government policies and incentives. The key policy is the renewable fuel standard (RFS) program that mandates minimum volumes for renewable fuels to replace or reduce petroleum-based transportation fuel consumption. The RFS has spurred significant investment in biofuels production infrastructure and provides long-term market certainty for the industry. Many states have additional biofuel mandates, tax incentives, and grant programs, further supporting market expansion. On July 12, 2023, the EPA established the applicable volumes and percentage standards for 2023 through 2025 for cellulosic biofuel, biomass-based diesel, advanced biofuel, and renewable fuel
- Energy Security and Environmental Goals: Another major factor driving biofuels adoption is their ability to enhance U.S. energy security and meet environmental goals. Biofuels reduce reliance on imported petroleum which is a key strategic objective. Domestically produced biofuels also support national energy independence and rural economic development. Most biofuels burn cleaner than gasoline and diesel that assists in meeting federal and state-level emissions reduction and carbon intensity targets. Life cycle assessments show biofuels can significantly lower greenhouse gas emissions as compared to fossil fuels.
- Advances in Biofuels Production Technologies: Ongoing advances in biofuels production technologies and yield improvements are decreasing costs and improving efficiency makes biofuels more competitive. For example, corn ethanol yields per acre have increased around 50% over the last decade through agricultural biotech innovations like drought-tolerant and pest-resistant seeds. Process innovations at biorefineries like corn fractionation, metal catalysts and cogeneration are also reducing energy and water use. For advanced cellulosic biofuels, enzyme and pretreatment innovations are improving conversion yields from lignocellulose biomass feedstocks. Renewable Energy Group (REG) is the leading biodiesel producer by production capacity in the U.S. As of January 2023, REG had an annual capacity of 432 million gallons. REG operates eight biodiesel plants, the largest of which is located in Washington State.
- Growth of Renewable Diesel and Sustainable Aviation Fuel: Renewable diesel can serve as a drop-in replacement for petroleum diesel, and is increasingly being used for ground transportation. SAF has the potential to substantially reduce lifecycle greenhouse gas emissions from aviation but requires further technological improvements and policy support to scale up. Major market players are actively investing in SAF.
U.S. Biofuels Market- Opportunities
- Leveraging Advanced Feedstocks: There is significant opportunity to leverage advanced biofuels feedstocks beyond conventional crops like corn and soybean. Cellulosic feedstocks like agricultural residues, forestry materials and energy crops like switchgrass can expand production without impacting food supplies. Waste-based feedstocks like municipal solid waste, plastics, and used cooking oil are another attractive option as these provide additional waste management benefits
- Expanding Availability of Biofuels: While ethanol is widely available at fueling stations nationwide, growth opportunities exist in expanding infrastructure and distribution for biodiesel and newer fuels like renewable diesel and sustainable aviation fuel (SAF). This require further build-out of biofuel storage capacity at transportation hubs and multimodal facilities. Partnerships with petroleum companies and fuel providers will increase availability at retail fueling sites. Broader distribution infrastructure will support increased consumer adoption and fleet utilization. In August 2021, the U.S. Department of Agriculture (USDA) invested US$ 26 million in biofuel infrastructure to expand the availability of higher-blend renewable fuels in 23 states of the U.S.
- Export Markets: Developing export markets for U.S. biofuels, leveraging trade partnerships represent another growth avenue. Countries in South America, Asia, and Europe represent potential target markets with blending mandates and emissions reduction objectives. However market development efforts must ensure appropriate social and environmental sustainability safeguards are in place to avoid unintended consequences. Partnerships with international organizations can help to establish global biofuels sustainability standards. According to the USDA Foreign Agricultural Service, the top 10 markets for U.S. biofuels in 2022 were Canada, South Korea, the European Union, Peru, Brazil, India, the Philippines, Mexico, the U.K., and Singapore
- Aviation and Maritime Sectors: The aviation and maritime sectors represent large addressable markets for renewable jet fuels and biodiesel to reduce emissions. These industries are exploring biofuels use through pilot studies and demonstration projects. R&D efforts on converting oils and fats into jet fuel are advancing. Biodiesel also has applications as a fuel additive in maritime shipping. Supportive policies boosts demand along with public-private partnerships can help scale adoption in these sectors.
U.S. Biofuels Market- Restraints
- High Production Costs: A key factor hampering further growth of biofuels is their high production costs as compared to petroleum fuels without policy incentives factored in. Corn ethanol and cellulosic ethanol costs are estimated to range from US$ 2.20-US$ 3.00 per gallon as compared to around US$ 2.00 for gasoline. Biodiesel production costs range from US$ 3.00-US$ 4.00 per gallon versus US$ 2.50 for diesel. Achieving cost competitiveness with petroleum through technological and process improvements remains a challenge.
- Lower Energy Density: Another limiting factor is the lower energy density of ethanol and biodiesel compared to gasoline and diesel. Ethanol has around 70% the energy density of gasoline, limiting volumetric fuel economy. Diesel vehicles converted to run on pure biodiesel also show a 10% reduction in fuel economy. The lower energy density requires more frequent refueling. Making engine and fuel system adjustments to fully optimize biofuels utilization remains an R&D need.
- Food Security Concerns: Using food crops like corn, soybean, sugarcane and palm oil as biofuel feedstocks has raised concerns regarding potential impacts on food supplies and prices, especially in developing nations. Biofuels expansion competes for finite agricultural land resources and water. However multiple factors affect food commodity prices, and evidence suggests biofuels have had a relatively small impact. Regardless, food security concerns have impacted policy support in some regions which could restrain the market growth.
