The Freeing Energy team is helping crowdsource the definitive list of cleantech investment firms.

Cleantech, energy tech, and power tech investors

We are looking at firms through three successively narrow filters:

  • Cleantech (or as it is often spelled, “clean tech”) – organizations that look at the broad spectrum of sustainability and green programs. This would include agriculture, recycling, building technologies, waste management, as well as energy.
  • Energy tech – this is a narrower filter of organizations focused on energy: fuels and electricity. This could include green hydrogen, fracking technologies, algae to biodiesel and, of course, electricity.
  • Power tech – the term is not widely used but it is an apt description of the area Freeing Energy focuses on, electricity.  This could include: solar, wind, geothermal, storage, batteries, power electronics, and electric distribution.

This guide will focus primarily on Power Tech. Firms with a specific focus in this area will receive star rankings to help viewers quickly find the most relevant firms. Check out our deep dive on the taxonomy underlying cleantech investments and investors at A blueprint for cleantech investing.

Cleantech and power tech investment stages

In terms of stage, this list is agnostic. This list includes:

  • Incubators (very early stage)
  • Venture capital (early stage)
  • Private equity (late-stage)
  • Project finance (longer-term, debt and tax equity focused firms looking to build and/or own projects, rather than technologies)
