Winners and losers: 8th - 22nd June 2007

THE WINNERS

1. Hoku Scientific +92.51%

On 14th June, Hoku jumped 47% in one day on news that its subsidiary, Hoku Materials, signed a 10-year contract for delivery of polysilicon with Suntech Power Holdings. The contract is thought to be worth $675 million in revenues over a 10 year period.

2. Dyesol Limited +40.82%

On 20th June, Dyesol announced significant progress in depositing dye solar cells onto steel substrates for use as roof cladding. This resulted in a new payment by Corus (still better known by its previous name, British Steel) and is part of an ongoing carrot approach by Corus to accelerate the development of the technology.

3. D1 Oils +36.98%

It was widely reported on June 15th that D1 was in advanced talks with an unnamed party regarding a strategic collaboration, some press reports even linking it with the giant oil company, BP.

4. Distributed Energy Systems +36.9%

Despite going through a period of great financial difficulty, DES have been clocking up some sales. In Malaysia, they have sold 2 of their NorthWind 100 wind turbines and a 100 kw pv system . And just yesterday, an order from Africa, for a hydrogen generation and storage system.

5. Petratherm +30.56%

Petratherm appears to be riding the wave of investor interest in Australian geothermal stocks, following strong political backing from the Australian Opposition leader, Kevin Rudd. Drilling deep underground to access the hot rocks takes a lot of money and these firms are looking for one-off government grants to do it. The opposition has pledged AUD 50 million to the geothermal sector, should they be elected.

THE LOSERS

1. China Biodiesel -21.72%

On 21st June, CB said that full-year earnings would be substantially below market expectations because of soaring feedstock prices. Concern is growing in general that recent flotations by Chinese companies on AIM have been much less than successful.

2. Western Geopower -21.54%

WG, a geothermal development company from Canada, appointed a new Director on 1st June and is continuing to develop a 25.5 Megawatt (net) geothermal power plant at The Geysers Geothermal Field in Sonoma County, California, United States as well as the South Meager Geothermal Project in British Columbia, Canada.

3. Biofutures International -16.67%

On 21st June, BI posted a full-year pretax loss of GBP 0.4 million in line with expectations. The company is also in advanced talks with several banks in Malaysia to raise debt finance to complete the first phase of its biodiesel plant.

4. CMR Fuel Cells -15.92%

On 21st June, CMR's annual report and accounts for 2006 showed a loss after taxation of GBP 1.3 million compared to 0.5 million for 2005.

5. VRB Power Systems -15.31%

VRB Power Systems have exciting technology - chemical flow batteries for energy storage which can link beneficially to intermittent power windfarms - and yet the last quarterly report from 30th May showed the company to have meagre sales revenue and high operating expenses.
