Ausra, Blackstone, and Fotowatio

In the last post, we examined how solar and later-stage investments are really driving the cleantech venture sector these days.  Nice of everyone to prove our point with the various deal and fund announcements this past week—thanks, guys!

  • Cyrium Technologies, a developer of high-efficiency solar cells for use in concentrator systems, announced a $15mm Series B led by The Quercus Trust, and including existing investors BDC Venture Capital, Chrysalix, and Pangaea Ventures.  It’s unclear how this relates to their insider round from December, whether that was an extension of the A or a bridge that rolled into this B.
  • Hydrogen sensor company H2Scan announced a $4mm fourth round (Series D?) of financing from new investor TGB Partners and existing investors Chrysalix, H5 Capital, Tri-Strip Associates, Ravinia Venture Fund, and members of the Tech Coast and Pasadena Angels groups.
  • VentureWire confirmed this week that Rive Technologies has raised a $14mm round of financing led by Nth Power, with participation from existing investors ATV and Charles River Ventures.

Cleantech investors in the news:

  • With the recent shift to later-stage investing, there’s been increasing angst about the seed capital gap in cleantech (we discussed it a while back).  More thoughts on the subject here and here.

Other news and notes:  Speaking of solar, Mark Modzelewski shares his blunt thoughts on the topic...  Here’s a useful comparison of the recent cleantech “boom” and the internet bubble from the late 1990s... Martin LaMonica writes about Obama’s cleantech-heavy energy plan...  As cleantech firms like A123, First Wind, and others line up to lead the charge in re-opening the IPO window, it’s worth looking back on the NYT’s assertion that VC activity in cleantech was one of the major reasons for the lack of IPO activity in the first half of the year (oops)...  Finally, here’s a pretty funny column by GTM’s Michael Kanellos.
