PRESS RELEASE 2009-06-04 Stockholm

Opcon and Swedish investors to take a 28 per cent share in Opcon’s Australian distributor

Opcon AB, the Swedish energy and environmental technology Group has committed itself to subscribe to a total of 44,3 million shares in a coming new share issue of Australian Enerji Ltd. (ASX:ERJ) that earlier today entered into a heads of agreement to acquire Opcon’s exclusive distributor for the Opcon Powerbox in Australia, CoGen ORC Power. The price has been set to 250 000 Euro and is expected to give Opcon around 14 per cent of Enerji after dilution.

Opcon has also arranged for a consortium of Swedish investors to subscribe to a further 44,3 million shares, amounting to another 14 per cent of Enerji. Thereby, Opcon together with other Swedish investors will control 28 per cent of Opcon’s Australian distributor.

CoGen ORC Power is a newly created “green tech” Company specializing in the application of waste heat recovery in conjunction with the Opcon Powerbox to generate complementary and base-load power. CoGen’s aim is to install a minimum of 170 MW of this zero fuel, zero emission generation capacity within five years. Each Opcon Powerbox generates up to 0,74 MW of CO2-free electricity.

“ With CoGen/Enerji we have got a knowledgeable and focused partner within Australia with its large distances and high electricity prices. In accordance with our strategy to take further steps in the value chain of the technology behind our Opcon Powerbox and increase shareholder value we are entering as owners of Enerji at the same time as CoGen/Enerji are being given the exclusive distribution rights for Opcon Powerbox in Australia. By this Opcon is supporting both CoGen’s business plan as well as its Enerji management, says Rolf Hasselström CEO Opcon AB.

“CoGen has been researching recovered energy solutions for 2 years now and, as a result, has been able to select the most advanced and efficient available. The Opcon Powerbox offers 40% more power, from the same recovered heat, than its closest known competitor and allows it to operate at temperatures as low as 55[o] C”, says Ross Smith Managing Director Enerji Ltd.

“CoGen/Enerji will own and operate the Opcon Powerbox as a Build Own Operate Model and simply sell the clean energy to the customer at attractive commercial rates. This model provides clear benefits to CoGen/Enerji’s customers and provides the company with an impressive return on capital – each MW of installed capacity costs approximately $2.5M with an annual income of $1.7M when applied to customers burning diesel”, says Ross Smith.

“By generating power without producing any additional greenhouse gas (GHG) emissions, CoGen Power offers a real and immediate solution to those businesses likely to be most heavily impacted by the Australian Federal Government’s Emissions Trading Scheme. Our proposal to our customers is to provide zero emissions electricity with no capital cost to them, sell them the power at a discount to what it costs

them to generate their own and reduce their GHG emissions by up to 30%”, says Ross Smith Managing Director Enerji Ltd.

The Opcon Powerbox is a product developed by Opcon for the production of new carbon-free electricity from waste heat at temperatures as low as 55°C. A standard Opcon Powerbox is at 0,74 MW and can be installed in large process-industry plants, power stations or with adaption, onboard larger ships. By utilizing waste heat, electricity is produced from a source that would otherwise go to waste.

PRESS RELEASE 2009-06-04 Stockholm

50 MSEK in large Australian order for five Opcon Powerbox

Opcon, the Swedish energy and environmental technology Group has won its largest Opcon Powerbox order to date, an order of five additional Opcon Powerbox to Australia for delivery 2009/2010. The order value is above 50 MSEK. The customer is Opcon’s partner CoGen ORC Power Australia (“CoGen”)/Enerji Ltd. That brings CoGen/Enerji’s orders to date to a total of six Opcon Powerboxes for delivery within a year.

CoGen, that has been given exclusive distribution rights in Australia initially focuses on a 2.3 million square kilometre area, roughly five times the size of Sweden, covering the Kimberly, Pilbara, Gasgoyne, Mid West and Southern Goldfields regions that are off the South Western Interconnected Grid (Western Australia). The target market consist of mines and remote regional centres/communities, the majority being supplied by on-site, fossil fuel electricity generation systems where fuel only costs for electricity production amounts to 32 cents AUD/kWh / 1,80 SEK/kWh.

Further, CoGen targets gas pipeline compressor pump stations, aluminium smelters, cement producers and other process industries with large amounts of waste heat all over Australia.

”We have more than 600 mining companies in Australia and over 350 major operating mines, with most of them off the grid, using their own costly power generation facilities. On the average mine site there is room for one or two Opcon Powerboxes. At large Iron Ore operations with 40 MW generation capacity or greater, more thorough studies have found that there is room for up to 14 Opcon Powerbox units. At the same time we have an extensive gas pipeline network in Australia where tremendous amounts of waste heat is lost at each pumping station. A single pumping station could have enough waste heat available for 14 Opcon Powerboxes. That says a lot about what economic and environmental potentials that we are looking at here”, says Ross Smith, Managing Director of CoGen.

“With its large distances and high electricity prices, Australia makes a very attractive market for Opcon Powerbox and our technology for carbon-free electricity production. The performance of our carbon-free electricity generating Opcon Powerbox will be very attractive to all these off the grid customers”, says Rolf Hasselström, CEO, Opcon AB

“Still, the opportunities at the Australian market are just the tip of the iceberg. Waste heat is a huge, largely untapped resource for producing new electricity around the world. According to the US Department of Energy there is more waste heat available in American industry than all of the electricity produced from all renewable energy sources in the US put together”, says Rolf Hasselström, CEO, Opcon AB.

The Opcon Powerbox is a product developed by Opcon for the production of new carbon-free electricity from waste heat at temperatures as low as 55°C. A standard Opcon Powerbox is at 0,74 MW and can be installed in large process-industry plants, power stations or with adaption, onboard larger ships. By utilizing waste heat, electricity is produced from a source that would otherwise go to waste.
