UNIDO India: Great Potential and Efforts to Increase Awareness of Concentrating Solar Thermal

Submitted by Baerbel Epp on December 2, 2016
Dr Anil MisraThe new interest subvention scheme for Concentrating Solar Thermal (CST) technologies administrated by the Indian Renewable Energy Development Agency (IREDA) is now open for applications. The scheme has been developed in cooperation with the UN Industrial Development Organisation (UNIDO) during the GEF-UNIDO-MNRE project, which focuses on increasing the deployment of concentrating solar thermal systems for process heat applications in India. “Technology providers or beneficiaries can use a short-term bridge loan at normal interest rates for pre-financing the 30 % capital subsidy that the Ministry of New and Renewable Energy grants for CST technologies,” explained Dr Anil Misra, National Project Manager at UNIDO (see photo). IREDA also hands out long-term loans covering up to 45 % of the benchmark system cost at 5 % lower-than-usual interest rates. The remaining 25 % are required as equity by the beneficiary.

Mexico: Second Solar Process Heat Case Study on Copper Mining

Submitted by Baerbel Epp on December 1, 2016
Mexico Copper MineArcon-Sunmark has announced the completion of a second solar-heated copper mine project. In September 2016, the Danish company installed a 6,270 m² collector field (4.4 MWth) at La Parreña in central Mexico. A 30 September press release said that the solar field would cover 58 % of the mine’s demand for heat. The field consists of 456 components of nearly 14 m² each and a storage tank of 660 m³. The first project of its kind, a field of 39,300 m² (27.5 MWth), was completed with a joint-venture partner at the Gabriela Mistral mine in Chile in 2013. Being the world’s largest solar system for process heat application, it had produced 142,000 MWh in the first 35 months of operation, the press release said. This corresponds to a specific yield of 1,112 kWh per m² and year.

Global Solar Certification Network: Facilitating International High-Quality Collector Trade

Submitted by Baerbel Epp on November 29, 2016
GSCN partnersThe recent approval of Working Rules means that the Global Solar Certification Network (GSCN) can now accept membership applications. The reuse of test and inspection reports in different certification schemes will be possible at the beginning of 2017. The GSCN was developed in Task 43 of the IEA Solar Heating and Cooling Programme to facilitate the cross-border trade of high-quality solar thermal products. The world map shows all the certification schemes which are already on their way into the GSCN – and more are said to follow soon. GSCN industry members can use a collector test report or a production inspection report from one of these schemes to apply for a certificate in another part of the world which is also part of GSCN. The procedure saves manufacturers time and money by removing the need for collector retesting or a second site inspection.

Chile: Consistent Electrolytic Bath Temperature Control Increases Copper Cathode Quality

Submitted by Baerbel Epp on November 28, 2016
Ian NelsonPampa Elvira Solar (PES) operates the largest solar process heat installation worldwide, a 27.5 MWth collector field at the Gabriela Mistral mine in Chile. “It´s an every-day, every-hour struggle to harvest the sun and earn our wages, so we may continue the very humble – and much too often neglected – business of running a solar heat-delivering system in the middle of the desert,” said Ian Nelson, General Manager of Pampa Elvira Solar. Solarthermalworld.org spoke with him about dust problems, the opportunities of concentrating collectors, the challenges of ESCO operation and improved copper cathodes. Five-and-a-half years ago, the engineer started at Energía Llaima, an independent producer of hydro and solar thermal solutions. PES, which was founded in 2012, is a consortium of Danish company Arcon-Sunmark and Energía Llaima.

New Zealand: Prized School Air Heating Project

Submitted by Baerbel Epp on November 26, 2016
Solarventi New ZealandA New Zealand research project which deployed solar air collectors in schools to improve pupils’ health while reducing heat costs has garnered an award by the New Zealand Institute of Building this year. Robyn Phipps, Professor in Construction at Massey University’s School of Engineering and Advanced Technology, won the award for her research project conducted in cooperation with the Australian subsidiary of Danish air collector manufacturer Solarventi. The project led to the installation of solar air heating systems in ten classrooms of five primary schools in wintertime in 2013 and to the implementation of another batch of systems in 12 classrooms of six primary schools the following winter. Monitoring data showed that attaining similar temperatures in the control classrooms required 2.5 times the thermal energy used in the solar-heated ones.

Solar Process Heat in Chile: “It is essential to use the ESCO model”

Submitted by Baerbel Epp on November 21, 2016
Roberto RomanThe world’s largest process heat installation has recently completed its third year of operation. The 39,000 m² collector field, which went online in October 2013 at Codelco´s Gabriela Mistral mine, is located 100 kilometres south of the town of Calama in Chile´s high central desert. Planning, delivery and installation of the solar field were done by Chilean-Danish joint-venture Pampa Elvira Solar, which has since been the operator of the system as well. The plant provides around 80 % of the energy required for the last step in copper production, the electrolytic refining of the metal in an acid bath. Solarthermalworld.org spoke with Roberto Roman, Associate Professor at the Faculty of Physics and Mathematical Sciences of the University of Chile. Roman has been part of a university team advising Codelco, Chile´s state-owned mining company, on solar mining from the very beginning.
