The funding comes from Qiming Ventures and Softbank China Venture Capital, and follows on from the Series A funding from K1W1 (a VC fund set up by Warehouse founder Sir Stephen Tindall), and Khosla Ventures (Vinod Khosla has recently visited NZ to speak at a conference I believe).
Lanzatech uses a proprietary bacteria to convert 'dirty' waste gases from industry into ethanol that can be used as a fuel. It has run a pilot plant scale development to prove the technology at the Glenbrook Steel Mill, out of Auckland, since 2007, and aims to have a pre-commercial scale plant built and active by 2011. The cool thing about this technology is that it can produce clean fuel and reduce the greenhouse gas emissions of industry at the same time. Also, the feedstock is readily available (esp. in China!) and doesn't compete with food or crops like some ethanol feedstocks such as corn.
The pool of capital available in NZ for such investments has always been low. China will increasingly become an option for NZ companies looking for funding, especially in Cleantech - an area that China will need to invest heavily in if it is to clean up it's environmental problems.
