State Laws & Incentives

Fuel Dispenser Labeling Requirement
All equipment used to dispense motor fuel containing at least 1% ethanol or methanol must be clearly labeled to inform customers that the fuel contains ethanol or methanol. (Reference Texas Statutes, Agriculture Code 17.051)                                                                                                                                                                                 

Renewable Fuel Promotion                                                                                                                The Texas Bioenergy Policy Council and the Texas Bioenergy Research Committee were established to promote the goal of making biofuels a significant part of the energy industry in Texas by January 1, 2019. The Policy Council is tasked with the following:

  • Provide a vision(PDF) for unifying the state's agricultural, energy, and research strengths in a successful launch of a cellulosic biofuel and bioenergy industry;
  • Foster development of cellulosic and bio-based fuels;
  • Pursue the creation of a next-generation biofuels energy research program at a university in the state;
  • Pursue federal and other funding to position the state as a bioenergy leader;
  • Study the feasibility and economic development effect of a blending requirement for biodiesel or cellulosic fuels;
  • Pursue the development and use of thermochemical process technologies to produce alternative chemical feedstocks; and
  • Study the feasibility and economic development of the requirements for renewable natural gas.

(Reference Texas Statutes, Agriculture Code 50D)

Federal Incentives

Alternative Fuel Infrastructure Tax Credit
(Originally expired 12/31/13 - retroactively extended through 12/31/16, by H.R. 2029) Fueling equipment for E85 installed between January 1, 2014, and December 31, 2016, is eligible for a tax credit of 30% of the cost, not to exceed $30,000. Station owners with multiple locations can use the credit towards each site. For more information about claiming the credit, see IRS Form 8911.

Ethanol Infrastructure Grants and Loan Guarantees
The Rural Energy for America Program (REAP) provides grants and loan guarantees to rural (population less than 50K) small businesses to purchase renewable energy systems or make energy efficiency improvements. Eligible renewable energy systems include equipment used to distribute flexible fuels. The maximum grant funding is 25% of project costs and the maximum loan guarantee is $25 million. The program is funded through fiscal year 2018 but is subject to congressional appropriations thereafter. For more information, see the REAP website.
