WASHINGTON (Reuters) - Ethanol derived from natural gas and coal would compete with corn-based ethanol for a share of the U.S. motor fuel market under a bill unveiled by six U.S. House members on Wednesday.
The bill would include ethanol produced from alternative sources, such as natural gas and coal, in the federal mandate for use of renewable fuels.
Corn ethanol accounts for the lion's share of renewable fuels, and second-generation biofuels have been slow to reach commercial viability.
