Spark Cleantech Accelerator
Entrepreneurial fellows in Innovation Crossroads, a US Department of Energy Lab-Embedded Entrepreneurship Program at Oak Ridge National Laboratory, will complete the Spark Cleantech Accelerator, a 12-week program offered by the University of Tennessee (UT), Knoxville, Spark Innovation Center at the UT Research Park.
The Spark Cleantech Accelerator was created in partnership with Evergreen Climate Innovations and other partners to support early-stage hard-tech businesses and drive commercialization of their technologies by leveraging the unique science and technology resources of East Tennessee.
By combining the resources of Innovation Crossroads and the Spark Cleantech Accelerator, we are building a stronger program for entrepreneurs.
