Who Are We?
EnviroMission Limited is developing Solar Tower renewable energy technology on a global scale. EnviroMission, which owns the global license to Solar Tower technology (excluding China), has shifted its development focus to the South West of the United States of America . A single power station development will have the capacity to supply renewable energy to more than 100,000 typical American households or remove the equivalent of 220,000 typical motor vehicles from the roads.
EnviroMission made an offer to acquire a majority holding in the securities of SMT to enable EnviroMission to commercialize Solar Tower technology globally, including large markets outside of Australia.
In May 2009, the company's U.S. subsidiary, EnviroMission (USA) commenced operations. The establishment of a US headquarters in Phoenix will provide financial and resource efficiencies from localized business operations. EnviroMission (USA), Inc. will lead briefings and interactions with power authorities and councils in the southwest, as well as analysts and the finance sector within the US to provide real time business advantage for development success in the region.
In June 2009, EnviroMission filed two land applications in the US for two prospective Solar Tower power station developments. The sites, now formally earmarked in Arizona, each total 5,500 acres (2225.85 hectares) suitable in size for development of a 200MW Solar Tower power station respectively.
EnviroMission started work on development back in 2001 with a search for the best possible site for the world's first Solar Tower power station.
A site was selected at Buronga in the southwest corner of New South Wales, on a former wheat and cattle station known in the district as Tapio Station, 23km north of Mildura. Tapio Station is mostly flat to undulating, semi arid and has the necessary solar radiation levels in close proximity to transmission grids.
EnviroMission has an option to purchase Tapio Station subject to the necessary land use changes and planning approvals being met.
Mildura is a major regional city with a population in excess of 50,000. It is has a regional airport, district hospital, universities, service industries, good housing stock and civil infrastructure being important considerations for successful integration of large infrastructure developments.
EnviroMission has maintained ongoing community consultation in Mildura and Buronga and has received strong support in favor of a Solar Tower being developed in the area.
Close to 15% of EnviroMission's shareholders live in the district, whilst the broader community has generally expressed encouragement for the project and the anticipated economic benefit expected to flow into the region as a result of development.
The region also forms an axis of the borders of three Australian States; Victoria, New South Wales, and South Australia.
Whilst EnviroMission now expects the first Solar Tower will be developed in the USA, it is felt international development will provide important leverage to increase development prospects in Australia. EnviroMission is seeking the strongest business case for development, and conditions in the USA support development ahead of Australia at this time.
EnviroMission commenced development of the European version of the concept known as the Solar Chimney under the terms of an exclusive licence with global developer, SolarMission Technologies, Inc.
The Solar Tower Project
EnviroMission's inspirational program to adapt and improve Solar Tower technology for Global market conditions and construct the world's first large-scale solar thermal power station is set to deliver a renewable energy solution that will also be a destination and extreme engineering icon.
The scale of the first 200MW power station will capture worldwide attention and attract significant added value through tourism and agribusiness.
A single 200MW Solar Tower power station will provide enough electricity to power around 100,000 typical American households, or remove the equivalent of 220,000 motor vehicles from the roads.
The energy output will represent an annual saving of more than 900,000 tonnes of greenhouse CO2 gases from entering the environment, with an outstanding Life Cycle Analysis of 2.5 years.
The Australian Solar Tower project has of six distinct phases:
- Project optimization (completed)
- Pre-Feasibility Commercialisation (completed)
- Final Feasibility (underway)
- Final Design and Construction
- Commercial Operation
EnviroMission is currently in the final feasibility phase of development which involves collaboration and project partnering to validate the economics of the project. The collaborative approach has also been central to harnessing critical technical expertise and resources to further progress the development of the technology in Australia.
The sun's radiation is used to heat a large body of air under an expansive collector zone, which is then forced by the laws of physics (hot air rises) to move as a hot wind through large turbines to generate electricity. A Solar Tower power station will create the conditions to cause hot wind to flow continuously through 32 x 6.25MW pressure staged turbines to generate electricity.
One of the major advantages of a Solar Tower over other renewable and traditional coal & nuclear energy producers is a Solar Tower does not use any water in the energy production process.
A US Department of Energy report 'Reducing water consumption of concentrated solar power electrictity generation', states coal, nuclear and heliostat CSP technology (power tower) utilize approximatley 500 gallons of water per MWh of power produced.
The Solar Tower project earmarked for Arizona will abate the approximate usage of 528 million gallons of potable water (drinking water) per annum.'

Small Scale Pilot Plant
Solar Tower technology has been tested and proven with a successful small-scale pilot plant constructed in Manzanares Spain. The pilot project was the result of collaboration between the Spanish Government and the German designers, Schlaich Bergermann and Partner.
The plant operated for seven years between 1982 and 1989, and consistently generated 50kW output of green energy.
The pilot plant conclusively proved the concept works and provided data for design modifications to achieve greater commercial and economic benefits associated with an increased scale of economy.
