✦ Synopsis

combined to offer an attractive solution to this problem. A 4-MWe, solarassisted natural gas power plant is under consideration for Tennant Creek in Northern Australia. This base-load power plant would employ a steam rankine cycle power conversion unit and incorporate an array of 2X directsteam-generating dishes wsith 400-m-aperture each. Preliminary experimental results indicate that 24.hour storage could be provided at an additional co\t of only I, qr;. Further results showed that a thermochemical ammonia system could demonstrate 24-hour base-load \olar power genrratlon for the same per-dish capital cost as a solar-only steam system without storage. 'This opens the market to megawatt-size, remote, offgrid applications. Pollution and greenhouse-gas emissions from such a closedloop \olar power generation system would he zero.
