Here’s a rundown of the corporate incubators dedicated to one industry, cleantech.

As the largest cleantech startup incubator in the United States, Greentown Labs focuses on the hardware sector.

The Shell incubator accepts partners on a limited basis: One example is Sangam Ventures, an India-based accelerator aimed at serving low-income communities.

Enel, a global renewable energy corporation, launched in March 2017 an innovation hub in partnership with CITRIS and Banatao Institute which is located at the CITRIS Foundry Accelerator on campus at UC Berkley.

Though technically an accelerator rather than an incubator, the Foundry offers $5,000 in cash to each startup selected, along with over $30,000 worth of infrastructure and services.

The Los Angeles Cleantech Incubator is just what it says on the label: It’s a partnership among public, private, and educational sectors all invested in helping cleantech businesses in their city.

Their stated aim is to reduce the energy impact of commercial buildings by aiding early-stage technologies with scalable models, and they work with over 30 accelerators and research institutions across the nation.
