A Somerville, Massachusetts-based cleantech accelerator has announced the 16 startups that will be a part of its new Houston incubator program.

Greentown Labs named the companies in the cohort this week just a few weeks after announcing the location of its new lab and workspace. The 40,000-square-foot space is being renovated from a former grocery store and is expected to open next spring.

"These early-access members are innovating across the key greenhouse gas-emitting sectors—including electricity, manufacturing, buildings, and more—and their solutions are helping create a sustainable future for all," reads a blog post on the company's website.

Here are Greentown Houston's inaugural members:
