Higher Diesel Prices Improve Biodiesel Economics as Global Biofuel Demand Raises Land-Use Questions

Rising diesel prices are improving the economics of biodiesel production, giving U.S. producers of soybean-based fuel a stronger market position. At the same time, growing global demand for biofuels is renewing questions about how much agricultural land may ultimately be needed to supply the industry.

Diesel Price Increase Narrows Biodiesel Cost Gap

Biodiesel made from soybean oil typically costs more to produce than conventional petroleum-based diesel. The industry has therefore relied heavily on government incentives and fuel-blending requirements that encourage or require refiners to incorporate renewable fuels into transportation energy supplies.

Recent increases in conventional diesel prices, however, have narrowed the price difference between petroleum diesel and biodiesel. That shift can improve margins for biodiesel producers because their renewable fuel becomes more competitive relative to traditional diesel.

For U.S. soybean farmers, stronger biodiesel economics can also support an important source of demand for soybean oil. Soybeans are processed into both meal, widely used in animal feed, and oil, which has increasingly become a feedstock for renewable fuels.

Global Biofuel Expansion Could Increase Pressure on Farmland

Agriculture Plays Growing Role in Transportation Energy

The broader challenge is the amount of agricultural production that could be required if global biofuel consumption continues expanding.

Renewable fuels made from crops occupy an unusual position in the energy transition. Unlike wind and solar projects, crop-based fuels depend on recurring agricultural production and therefore compete for resources including farmland, water and fertilizer.

Expanding production of soybean oil and other crop-derived fuels could consequently increase pressure on agricultural acreage, particularly if transportation fuel demand rises faster than improvements in crop yields or the availability of alternative feedstocks.

The potential land requirement has become significant enough to invite comparisons with the size of entire U.S. states, including Montana, highlighting the scale of agricultural resources that could be involved in meeting future worldwide biofuel demand.

U.S. Policies Remain Important to Biodiesel Market

Government policy continues to play a central role in the economics of renewable diesel and biodiesel.

Federal and state programs can influence how much renewable fuel refiners blend, while subsidies and other incentives can offset the higher production costs associated with some biofuels. Changes in those programs can therefore affect demand for soybean oil and other agricultural commodities used as feedstocks.

At the same time, movements in petroleum markets can alter the equation independently of government support. When conventional diesel becomes more expensive, the additional cost of producing biodiesel represents a smaller premium compared with fossil fuel.

That dynamic is currently providing a more favorable environment for producers selling diesel derived partly from agricultural crops.

Energy Demand Connects Fuel Markets With U.S. Agriculture

The relationship between diesel prices and soybean-based fuels illustrates the increasingly close connection between agriculture and energy markets.

Higher demand for renewable fuels can create additional markets for American farmers and agricultural processors. However, a large-scale expansion of crop-based fuel production can also affect land use and commodity markets, especially when the same crops are needed for food, animal feed and energy.

The long-term balance will depend on several factors, including energy prices, government policies, agricultural productivity and the development of renewable fuels that rely on waste products or other non-food feedstocks.

For now, elevated conventional diesel prices are making biodiesel more economically attractive. But as governments and industries pursue greater use of renewable transportation fuels, the amount of farmland required to meet that demand is likely to remain an important part of the broader debate over the future of biofuels.
