Certain Biofuel Mandates Unlikely to Be Met by 2022
Unless New Technologies, Policies Developed
WASHINGTON — It is unlikely the United States will meet some specific biofuel mandates under the current Renewable Fuel Standard by 2022 unless innovative technologies are developed or policies change, says a new congressionally requested report from the National Research Council, which adds that the standard may be an ineffective policy for reducing global greenhouse gas emissions. Achieving this standard would likely increase federal budget outlays as well as have mixed economic and environmental effects.
In 2005, Congress enacted the Renewable Fuel Standard as part of the Energy Policy Act and amended it in the 2007 Energy Independence and Security Act. The amended standard mandated that by 2022 the consumption volume of the renewable fuels should consist of:
- 15 billion gallons of conventional biofuels, mainly corn-grain ethanol;
- 1 billion gallons of biomass-based diesel fuel;
- 4 billion gallons of advanced renewable biofuels, other than ethanol derived from cornstarch, that achieve a life-cycle greenhouse gas threshold of at least 50 percent; and
- 16 billion gallons of cellulosic biofuels produced from wood, grasses, or non-edible plant parts -- such as from corn stalks and wheat straw.
Except for biodiesel, these volumes are measured in ethanol units.
The committee that wrote the report said that production of adequate volumes of biofuels are expected to meet consumption mandates for conventional biofuels and biomass-based diesel fuel. However, whether and how the mandate for cellulosic biofuels will be met is uncertain. Currently, no commercially viable biorefineries exist for converting cellulosic biomass to fuel. The capacity to meet the renewable fuel mandate for cellulosic biofuels will not be available unless the production process is unexpectedly improved and technologies are scaled up and undergo several commercial-scale demonstrations in the next few years. Additionally, policy uncertainties and high costs of production may deter investors from aggressive deployment, even though the government guarantees a market for cellulosic biofuels up to the level of the consumption mandate, regardless of price.
