Tell Us About You and Your Company

We are a 501vc™ cleantech accelerator focused on investing and supporting the next generation of energy innovation.

To date, Clean Energy Trust has awarded over $5M in funding to 45 clean energy startups. Startups benefitting from our programs and support have gone on to raise an additional $139M follow-on funding – and have created over 300 jobs.  

Clean Energy Trust typically makes investments of between $100,000 and $300,000 through a convertible note in companies it selects through an annual cycle that culminates in May of each year.
In conjunction with this investment process, Clean Energy Trust runs an accelerator program that invites companies to Chicago for a couple days of group and individual workshop sessions, along with pitch presentation design and coaching. For the accelerator program, Clean Energy Trust doesn't provide any guaranteed funding (beyond travel stipends) or take equity.
We currently have a portfolio of 23 companies across building controls, energy storage, energy management, and water tech, in companies from Kentucky to Kansas.
