Clean Sweep 71

A round-up of recent news in clean technology and cleantech investment.

Deals
Wave power developer Aquamarine Power raised £10m to support offshore testing of its Oyster device. Investors include Scottish & Southern Energy and Sigma Capital, who previously backed Aquamarine in 2007.
The Oyster is a hydro-electric wave energy converter, which uses the motion of the sea to pump high-pressure water to an on-shore generator. Each device has an effective peak output of 300-600kW. Edinburgh-based Aquamarine says it needs around £50m to commercialise Oyster, and will be launching another funding round shortly.

London-based smart grid operator ResponsiveLoad (aka RLTec) has secured an extra £5.8m. New investors Naxos Capital Partners and Carbon Trust Investments joined Low Carbon Accelerator (which committed an extra £1m).
LCA also announced £283 follow-on funding for quantum well PV developer QuantaSol.

Automotive fuel efficiency group Lysanda has secured a £1.3m second round from the Sustainable Technology Fund, managed by Curzon Park Capital.
Essex-based Lysanda provides emissions monitoring systems such as its Eco-Log product, which allows fleet managers to monitor their vehicles' fuel consumption and emissions based on real-time data from on-board diagnostic systems. In tests, the system delivers average fuel savings of 23%.

Wastewater treatment firm Bluewater Bio has raised a further £2m funding. Aqua Resources Fund, which invested £2.3m April put in another £1.5m.
London-based Bluewater is commercialisting an activated sludge technology called HYBACS, which can reduce the energy consumption and land requirements of treatment plants.

Welsh water monitoring firm Envirogene raised a £500k interim round from Finance Wales, RAB Capital and others. Envirogene, which raised a £1m second round last December, provides molecular diagnostics and nanoparticle tracing technology for the bioremediation and environmental monitoring sectors.

London-based I2BF Venture Capital led a $9m bridging round in South Korean ultracapacitor manufacturer Nesscap. Ultracapacitors are an emerging energy storage tech for automotive, micro-generation and other markets.
I2BF is an energy-focused subsidiary of Russian asset manager Arbat Capital Management.

Austrian biomass developer Cycleenergy secured a Euro10m second round led by the New Energy Fund run by Portugal's Banif Investment Managers. Existing investors 3i and 3TS Capital Partners also joined in.
The funding will allow Cycleenergy to double its current portfolio of three cogeneration plants.

Over the pond, greenconstruction group Serious Materials raised a $60m third round led by Mesirow Financial Capital. The deal is believed to be the largest to date for the energy-efficiency sector.
The California firm produces sustainable building materials such as energy-saving windows and non-gypsum drywall.
Also in Californian green building, Soladigm raised $20.7m - investors include the redoubtable Khosla Ventures and Sigma Partners.

More funding for a couple of Californian microbial biofuel developers: LS9 raised a $25m third round from Chevron Technology Ventures and others; and Amyris announced it had raised $41.75m of its planned $60m third round.

Still in California, solar installer Sungevity raised $6m to expand across the state. New investor Greener Capital led the round.

And San Diego's Achates Power has raised $12.12m of a planned $20m round, with existing investors including Sequoia Capital, InterWest Partners, Rockport Capital Partners and Madrone Capital Partners. Achates is developing a highly efficient diesel engine based on the Junkers Juno, but is keeping details close to its chest.

In one of those slightly tangential deals, Texas-based waste disposal group Liquid Environmental Solutions raised $20m from cleantech specialist Craton Equity Partners. LES specialises in collecting and treating grease and food waste from fast food outlets, school cafes and other establishments - if it's not then recycling it as a biofuel feedstock, it might be missing a trick.

Some of the biggest individual rounds went to US companies which have secured significant government funding - including rooftop PV provider Solyndra (which last month raised a whopping $198m, mostly from existing investors) and electric car maker Tesla Motors, both of whom received around half a billion's worth of loan guarantees to fund new factories. Now, that's what I call a stimulus.
