Optimization of a Low Temperature Solar District Heating System by Integrating Space and Domestic Hot Water Loads (2014)

Submitted by Chris Heron on July 11, 2014

This presentation on the optimization of a low temperature solar district heating system was given by Canmet ENERGY at the 2nd International Solar District Heating Conference in Hamburg in June 2014.  After a short introduction on Solar District Heating in Canada, the presentation focuses mainly on the only solar district heating site nationwide, named Drake Landing,  and shares information on its capacity, performances and technology.  The speaker also provides the results of a comparison study where domestic hot water is supplied by a standalone SDHW like the one in Drake Landi

Ukraine: Political Instability Hurts Business

Submitted by Baerbel Epp on July 11, 2014
AfrosUkraine’s solar thermal market has been adversely affected by the country’s currently very unstable economic, political and social situation. The industry agrees that customers are cautious about spending money during politically and socially uncertain times. Solar thermal stakeholders also note that one of the failures of the government and of politics in general has been to not follow through with laws, projects and promises, something which has almost become a tradition in every field, including renewables. Solarthermalworld.org spoke with some of the collector manufacturers and importers about their business situation in times of widespread instability.

Integrating Solar Thermal in Buildings – A Quick Guide for Architects and Builders (2014)

Submitted by Chris Heron on July 9, 2014

This guide was written as part of the Global Solar Water Heating (GSWH) Market Transformation and Strengthening Initiative, which is the result of a joint collaboration between the European Solar Thermal Industry Federation and the Global Environment Fund (GEF) of the United Nations Environment Programme (UNEP).

Bulgaria: Experts Discuss Solar Thermal at Renewable Energies in Buildings Conference

Submitted by Baerbel Epp on July 9, 2014
Uwe TrenknerOnce again, Bulgaria is facing political turmoil, with early elections due to take place in autumn. The outgoing cabinet of Prime Minister Plamen Oresharski has been embroiled in fierce disputes with both the conventional and the renewable energy sector. For example, when the government had tried to keep electricity prices low for political reasons, no public or private utility affected by the government’s decision received any kind of compensation for its losses. On 17 June, German and Bulgarian renewable energy experts and business representatives, among them solar thermal system manufacturers, gathered for the Renewable Energies in Buildings conference organised by the German-Bulgarian Chamber of Industry and Commerce. Uwe Trenkner, a former Secretary General of the European Solar Thermal Industry Federation, used the conference to speak about solar heating and solar cooling for buildings. “Obviously, the solar heat market in Bulgaria isn’t doing so well,” he said regretfully.

Hawaii/California: Sopogy Goes into Liquidation after More than a Decade in Business

Submitted by Baerbel Epp on July 7, 2014
After the Hawaiian manufacturer of parabolic trough systems, Sopogy, has stopped operations, its assets are now being liquidated as well. According to Pacific Business News (PBN), an attorney based in Los Angeles is handling the insolvency proceedings. While the PBN news piece was published in April 2014, Sopogy’s main phone line had already been out of service when German agency solrico carried out its research for the World Map of Solar Process Heat Collector Industry in late 2013. In the meantime, the company´s website has also been taken offline.
 

The Gaby Project: Large Scale Solar Plant for Chilean Copper Mines (2014)

Submitted by Chris Heron on July 4, 2014

This presentation was given by Sunmark Solutions’ Leo Holm at the International Solar District Heating Conference, held from 3-4 June in Hamburg, Germany. The speaker explains how his company built a large scale solar plant, the Pampa Elvira Solar Project, on one of CODELCO’s mining operations in Gabriela Mistral in the middle of the Atacama desert in Chile where weather conditions can be extreme.  

New ECOWAS Solar Thermal Energy Program : Background, Components, Process (2014)

Submitted by Chris Heron on July 3, 2014

On 13 June 2014, Hannes Bauer, Solar Thermal Program Manager at ECREEE, ECOWAS Center for Renewable Energy and Energy Efficiency, gave a workshop in Cabo Verde on the new ECOWAS (Economic Community of West African States) Solar Thermal Energy Program. 

The 1st part of the presentation focuses on the global market growth of solar thermal collectors, showing that from 2000 to 2010 the market has increased steadily by 20% each year. It also shows that West African States were not participating during that period. 

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.

Romania: Support Programmes to Increase SMEs’ Energy Efficiency

Submitted by Baerbel Epp on June 30, 2014
Romania has until 2020 to improve its energy efficiency by 20 % in order to comply with the EU Climate and Energy Package. Because a substantial share of the country’s greenhouse gas emissions is caused by industrial enterprises, offering a special renewable incentive for these companies seemed the logical thing to do - hence, the new grant programme, which started in March 2014 and addresses small and medium enterprises (SMEs). The energy efficiency programme for SMEs, RO 05, is funded by EUR 8 million of EEA grants from the European Economic Area Financial Mechanism.
 

Ukraine: First Demonstration Projects Pave the Way for Solar District Heating

Submitted by Baerbel Epp on June 30, 2014
Ukraine District HeatingTheoretically, the district heating networks from Soviet times could very well be supplemented by solar thermal heat. Except Poland, however, no eastern European state has had much experience with solar thermal district heating. Bulgaria and Romania have not yet had any plans or projects to combine district heating with solar thermal, but Ukraine has already taken the first step: Between 2008 and 2012, municipal utility Mariupolteploset, one of the biggest heat suppliers in Ukraine, set up three solar fields across Donetsk in eastern Ukraine, with all of them feeding into district heating networks. Other municipalities have also announced the construction of their first solar district heating demonstration systems when modernising local power stations and energy distribution networks.
