Although Firelake Capital was started to invest mainly in public cleantech companies, the firm has decided to open a new $100 million fund for private sector investments.

Managing director Martin Lagod told us that the firm's focus on new technologies won't change. Firelake is considering investments in energy distribution and generation, transportation, water and carbon mitigation technologies.

The firm's original evergreen fund will no longer invest in the private sector, although it will maintain its position in over a dozen private companies (full list here).

The new fund, Strategic Technology Fund II, is expected to close in January. Firelake is based in Palo Alto, Calif.
