Dear Solarthermalworld.org Reader,
Solar
energy applications in mining have a bright future ahead thanks to both
economic and environmental benefits. One successful case study is
Chile’s Gabriela Mistral mine: The 39,300 m² (27.5 MWth)
field is the world’s largest solar process heat plant and it has
produced an average of 1,112 kWh/m²a in its three years of operation.
“We have realised that the efficiency of flat plate collectors is not as
affected by a thin layer of dust – which you always have in the
surroundings of mines – as is the one of mirrors in CSP plants,” said
Ian Nelson (right photo), General Manager of Pampa Elvira Solar, the
energy service company (ESCO) which operates the huge plant.
From
the start of the tender process, Roberto Roman (left photo), Associate
Professor at the Faculty of Physics and Mathematical Sciences of the
University of Chile, had emphasised that ESCO use was essential, as the
company in charge of the operation had a first-rate interest in
attaining optimum performance. The interviews with the two experts from
Chile are available in full as part of this newsletter.
Have a good read and sunny regards
