Twelve energy companies pitched their businesses "Shark Tank"-style at Ameren’s headquarters in St. Louis on Monday. 

The companies, from around the world, are all vying for a spot in the 12-week Ameren Accelerator, which this year focuses on smart cities. The winning companies — up to nine — will also each receive a $100,000 check.
