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 .
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
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.
A range of suitable sites have been identified within close proximity to Australia’s national electricity grid for commercially viable transmission of a Solar Tower’s clean green power – EnviroMission has already exercised its option to purchase its preferred site for the world’s first Solar Tower power station at Buronga, in the Wentworth Shire of New South Wales.
Australia’s leading construction and operating standards will ensure the project meets the highest engineering standards which is an important consideration for future export of the technology.
The Australian community is environmentally aware and wants projects that will address concerns about the ongoing damage to the environment. Government support and incentives for renewable energy is increasing through positive review and legislation
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 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.
The Solar Tower project earmarked for Arizona will abate the approximate usage of 528 million gallons of potable water (drinking water) per annum.’
