National Laboratory Technology Maturation Act of 2014 - Requires the Secretary of Energy (DOE) to establish the National Laboratory technology maturation program to make grants of up to $5 million per fiscal year to National Laboratories to increase the successful transfer of technologies licensed from National Laboratories to small businesses by providing a link between an innovative process or technology and a practical application with potential to be successful in commercial markets.
Requires grant recipients to use the funds to provide vouchers of up to $250,000 each to small businesses that hold a technology license from a National Laboratory to pay the cost of providing assistance from its scientists and engineers to assist in the development of the licensed technology and further develop related products and services until they are market-ready or sufficiently developed to attract private investment.
Requires a National Laboratory that awards a voucher to carry out such a project to: (1) establish a procedure to monitor interim progress of the project toward commercialization milestones, and (2) discontinue providing such funding or assistance if it determines that a project is not making adequate progress toward such milestones under the procedure.
