USA: S.O.L.I.D. Operates 3.4 MWth Cooling System as ESCO in Arizona

Submitted by Baerbel Epp on August 29, 2014
Desert Mountain High SchoolIt is an ideal location for solar cooling use: Scottsdale, a US city in the Greater Phoenix area in Arizona enjoys an average of 312 days of sunshine every year. Between May and September, temperatures rise above 38°C and can even reach 46°C on a hot day. This is where in July 2011, Austrian company S.O.L.I.D has started to plan a solar cooling system for Scottsdale’s Desert Mountain High School (DMHS) of 2,600 students. Three years later, the 3.4 MWth (4,865 m² of collector area) system went into operation and is now supplying heat to a single-effect lithium bromide absorption chiller with a cooling capacity of 1,750 kW. The solar cooling installation at the DMHS is currently the largest of its kind in the world, having surpassed the 2.7 MWth solar thermal capacity (3,900 m²) of another S.O.L.I.D system at the United World College (UWC) in Singapore.

South Africa: Fresnel Collectors Keep It Cool in MTN’s Server Rooms

Submitted by Baerbel Epp on August 28, 2014
Industrial SolarSince June 2014, a Fresnel collector field with 242 kWth has been feeding into the district cooling system of the MTN Group at its headquarters in Johannesburg, South Africa. MTN, which has more than 200 million customers, as well as subsidiaries in 22 countries across Africa and the Middle East, is one of the leading mobile operators in South Africa – and it is aware of the impact of global warming. “We continuously explore ways in which we can lessen the impact of our operations on the environment. This initiative will not only reduce our carbon footprint but it will substantially reduce our electricity consumption, which will release additional capacity for the national grid,” MTN’s CEO, Zunaid Bulbulia, was quoted as saying in a press release from 17 July 2014. The concentrating solar thermal plant powers the double-effect absorption chiller whose cooling capacity of 330 kW keeps temperatures low in the data centre at MTN’s head office.

Solar Air-Conditioning System Using Single-Double Effect Combined Absorption Chiller (2014)

Submitted by Chris Heron on July 30, 2014

This presentation on solar air-conditioning system was given by Kawasaki’s Hajime Yabase, together with Kiyoshi Saito of the Waseda University and Muhammad Idrus Alhamid of the University of Indonesia, at the ATMOsphere conference which took place in Tokyo from 3 to 5 February 2014.  The speakers outlined the numerous advantages of using double-effect absorption chillers in solar air-conditioning system.

SHAAMS report: WP 4: The Regional State of the Art in Crete Region (2013)

Submitted by Chris Heron on July 25, 2014

This report, published by SHAAMS, the Strategic Hubs for the Analysis and Acceleration of the Mediterranean Solar Sector, provides a general picture of the solar energy sector in Crete and makes a SWOT analyses.  It shares information on the regional solar policies and strategies already in place, on R&D projects and awareness campaigns.  With regards to solar thermal energy, the report says it is mainly used for hot water production in household buildings and in hotels.  There are very few applications in industry and agriculture.  New technologies, like solar thermal cooling and space

Solar Thermal Cooling: Technology, Cost and Case Study (2014)

Submitted by Chris Heron on July 16, 2014

IRENA, the International Renewable Energy Agency, together with the Government of the Republic of Cyprus organized an event on renewable energy applications for island tourism.  During this 2-day conference, Panagiotis Tsekouras, Mechanical Engineer at CRES, the Greek Center for Renewable Energy Sources and Savings, reported on solar thermal cooling in the tourism industry.  It shows that the use of solar thermal energy for cooling system helps saving money, reducing the electricity use by 87% and is a big step towards green tourism.

The report was prepared by Franz Mauthner and Werner Weiss of AEE INTEC in the framework of the Solar Heating and Cooling Programme (SHC) of the International Energy Agency (IEA).  This report gives a detailed overview of the solar thermal market evolution by the end of 2012 in 58 countries, representing 95 % of the overall market worldwide.

Germany: SunOyster’s New Approach to Combine PV and Solar Heat

Submitted by Baerbel Epp on July 1, 2014
SunOysterSunOyster Systems (SOS) based in Halstenbek, a town near Hamburg, Germany, has developed a new technology for the combined generation of solar heat and electricity (PVT). The first six SunOyster units are currently on their way to the Chinese town of Shuouzhou, 400 km west of Beijing. Yonghao Gangue Power Plant bought the system to feed electricity into its grid, as well as to supply heat to its district heating network. The network provides both space heating for an industrial area in winter and heat for a 10 kW adsorption chiller in summer. The photo shows company founder Carsten Corino next to the SunOyster demonstration unit at the company site in Halstenbek. The mirror on the left has been placed higher than the one on the right to minimise shading.

REN 21: Solar Thermal Contributes Significantly to Hot Water Production

Submitted by Baerbel Epp on June 30, 2014
top ten 2012According to REN21’s Renewables 2014 Global Status Report, which was published at the UN-hosted Sustainable Energy for All Forum in New York at the beginning of June, solar thermal technologies contribute significantly to hot water production in many countries and increasingly to space heating and cooling, as well as industrial processes. REN21 is a global multi-stakeholder network for renewable energy policy, connecting key actors from governments, international organisations, industry associations, science and academia, as well as civil society. First released in 2005, the report provides a comprehensive and timely overview of renewable energy markets, industries, investments and policy developments worldwide. The renewable energy data is provided by an international network of more than 500 contributors, researchers and authors. According to report data, the world added 55.4 GWth (more than 79 million m2) of solar heat capacity in 2012, increasing the cumulative installed capacity of all collector types in operation by over 14 % for a year-end total of 283.4 GWth. The chart above shows the shares in global capacity in operation across 2012’s top ten countries.
