Belo Horizonte – Brazil´s Solar Capital

Submitted by Baerbel Epp on October 25, 2017
Belo HorizonteBelo Horizonte, a municipality about 600 km north of Sao Paulo in the state of Minas Gerais, is also known as the solar capital of Brazil. Not only does it have a population of about 2.5 million, but solar water heater installations on many of its high-rise multifamily buildings. The photo shows one example, a block of flats for the wealthy middle class. The roof is completely covered in solar water heaters, which meet around half of the annual hot water requirements. This article will present the main drivers of an exciting market development in Latin America: a university research group specialised in solar heating and cooling, committed system planners, strong manufacturers and a pro-solar state utility.

Solar Cooling: From Research to Market Competitiveness

Submitted by Baerbel Epp on October 6, 2015
Otti SAC 2015Diligent research on small scale low-temperature chillers, the launch of a new generation of compact solar cooling units and large-scale plants able to compete economically with conventional cooling solutions: These are just some of the main trends which were discussed during the 6th International Conference on Solar Air-Conditioning organised by German company East-Bavarian Institute for Technology Transfer, OTTI, Rome, Italy, on 24/25 September. The photo shows Conference Chairwoman Prof Ursula Eicker from the University of Applied Sciences, Stuttgart, Germany (forth from left in first row) together with the international scientific committee consisting of researchers from Germany, Spain, Greece, Italy, France, China, Austria and Cyprus.

France, Italy and Brazil: Programmes for Dedicated Solar Heating and Cooling Conferences

Submitted by Baerbel Epp on May 22, 2015
Conference LogosSolar thermal professionals who have taken an interest in solar district heating, in solar air conditioning or the Brazilian solar thermal market will be able to participate in dedicated conferences over the next months, namely the 3rd International Solar District Heating Conference in Toulouse, France, on 17-18 June, the 6th International Conference on Solar Air Conditioning in Rome, Italy, from 24-25 September and the 3rd Brazilian Solar Heating Congress in São Paulo, Brazil, between 2-3 September. All three events have already released their conference programme.

“Very few countries have policies explicitly supporting renewable deployment in the industry sector”

Submitted by Baerbel Epp on March 2, 2015
Ruud KempenerThe International Renewable Energy Agency (IRENA) published two technology briefs last week. The 40-page documents, one entitled Solar Heat for Industrial Processes, the other Solar Heating and Cooling for Residential Applications, give a brief global overview of the market and technology development, including some recommendations for policy makers (see attached documents). It is the first time that the solar thermal sector is in the focus of a technology brief. The studies were published under the Energy Technology Systems Analysis Programme (ETSAP) of the International Energy Agency. spoke with one of the authors, Ruud Kempener, Technology Roadmap Analyst at the IRENA Innovation and Technology Centre in Bonn, Germany.

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.

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.

Solar Cooling Market to experience big Changes

Submitted by Baerbel Epp on July 18, 2011

 Uli Jakob” According to Dr Uli Jakob, Vice President of the “Green Chiller - Association for Sorption Cooling”, the solar cooling sector may soon experience a shift from small series production of a niche market to considerable manufacturing quantities. Jakob points out two signs supporting such a development: First, the approval of the IEA-SHC task 48, “Quality Assurance and Support Measures for Solar Cooling“; second, the recent market entry of big players, such as Stiebel Eltron (Germany) and Hitachi (Japan).

Brazil: Solar Cooling System from Germany for Eco-Hotel Pousada do Parque

Submitted by Baerbel Epp on January 28, 2011

Solar Cooling System at Pousada do Parque” Since the beginning of 2011, solar cooling technology from Thuringia/Germany ensures a pleasant indoor climate in the rooms of the eco-hotel Pousada do Parque in Cuiabá, Brazil. On 15 January, the pilot plant came into operation, and since then, it has not only provided cold water, but also important input for a current campaign to accelerate the use of solar cooling technology in the Brazilian hotel sector.
