Solar heat in Vietnam, the new workshop of the world

Submitted by Baerbel Epp on January 4, 2018
PrimeAsia Leather CompanyA 5,000 m² flat plate collector field is currently being built at PrimeAsia Leather in Ba Ria-Vung Tau, Vietnam. The turnkey supplier of the installation is Danish-based Arcon-Sunmark, which has its own flat plate collector production facilities in this South East Asian country. According to a press release published at the beginning of last November, the solar plant is scheduled to come online in early 2018. The solar heat is said to be used for preparing the animal skins and evaporating the factory’s waste water.

Project partners guarantee SDH yield

Submitted by Baerbel Epp on December 21, 2017
ADEME15 December saw the inauguration of the first installation supported by the subsidy scheme for large-scale solar thermal projects in France. The 2,340 m² collector field by German manufacturer KBB Kollektorbau has since been feeding into a biomass district heating network of Châteaubriant, a town in western France. Altogether, the subsidy scheme’s administrator, French energy agency Ademe, approved six solar thermal projects during the first tender invitation called Appel à Projets National Grandes Installations Solaires Thermiques. The second one in November 2017 led to the submission and approval of a 14,000 m² solar process heat project, which is currently in planning. The programme inviting large-scale solar thermal tenders started in 2015 (see the database of incentive programmes for more information). There are two new submission deadlines planned for March and November 2018.

Australia: Think Big, Think Solar

Submitted by Baerbel Epp on December 1, 2017
GreenlandIn Australia, the deployment of large commercial solar thermal plants is picking up speed. This year, Monash University had a solar field of 0.5 MW put into operation and aims to expand it to 1 MW. The solar heat that is fed into the district heating system of the large campus area in Clayton, a suburb of Melbourne, is said to meet the entire heat demand in summer. The field consists of vacuum tube collectors by Australian manufacturer Greenland Systems (see photo) and was designed and installed by the LCI engineering consultancy from Melbourne. Currently, Danish Aalborg CSP is in dialogue with Perth-based Agrimin about the supply of solar process heat to a planned sulphate of potash (SOP) mine and processing factory in the state of Western Australia.

SHC 2017: Largest experts’ meeting on integrated solar heating and cooling

Submitted by Baerbel Epp on November 8, 2017
SHC2017_1500 experts from more than 50 countries attended the 5th International Conference on Solar Heating and Cooling (SHC) in Abu Dhabi, UAE, from 30 October to 2 November 2017. It was the first time that this biennial conference by the IEA’s Solar Heating and Cooling Programme had been organised jointly with the Solar World Congress by the International Solar Energy Society (ISES). The new partnership resulted in 2017’s largest experts’ meeting on integrated SHC solutions for buildings, industry, cities, regions and utilities, and in over 300 presentations.

Slovenia: On the Path to Renewable District Heating

Submitted by Baerbel Epp on October 2, 2017
Rok SunkoDistrict heating networks supplied by renewable energy sources (RES) are widely recognised today as one of the most effective ways to decarbonise the heating sector. The EU’s CoolHeating project has been supporting the implementation of small, modular renewable heating and cooling grids for towns in southeastern Europe by transferring knowledge from leading countries such as Austria, Denmark and Germany to newcomers, for example, Bosnia-Herzegovina, Croatia, Macedonia, Serbia and Slovenia. It has also led to the publication of a handbook – Small modular renewable heating and cooling grids – available in seven languages (see the attached PDFs). Solarthermalworld.org talked to Rok Sunko (see photo) from one of the project partners, Skupina Fabrika about current developments and the outlook of RES district heating in Slovenia. The company is a Slovenian-based R&D business focusing on renewables, IT solutions and branding.

IEA SHC Task 52: Solar Thermal’s Role in 2050 Energy Mix

Submitted by Baerbel Epp on September 29, 2017
Collector Installation in HamburgWhat role solar thermal will play in the energy sector in 2050 is one of the principal questions that the international Task 52 research project Solar Heat and Energy Economics in Urban Environments intends to answer. As part of this IEA Solar Heating & Cooling Programme task, Denmark’s Aalborg University chose four major solar thermal countries in Europe – Austria, Denmark, Germany and Italy – to model their 2050 solar share in national heat production. The university’s estimates range from 3 to 12 % based on country and scenario, which would require 4 to 175 million m² of collector area in each of the four nations. The solar share of all four was rather similar in high penetration scenarios, although climate, energy demand and network design vary significantly. That’s why the researchers from Aalborg concluded that “the findings can be applied to a variety of energy systems, including in countries that are not directly part of this study.” They also underlined the importance solar thermal could have in reducing pressure on scarce resources such as biomass.

Lithuania: Can Solar Thermal Beat Low Biomass Heat Prices?

Submitted by Baerbel Epp on August 14, 2017
Lithuania District HeatingWith biomass prices on the rise, solar district heating could become profitable in Lithuania. But without investment grants, payback periods were still too long, it said in the conclusion of a 2015 SDH market study by LEI, the Lithuanian Energy Institute (see the attached document in Lithuanian). The photo shows the country’s first SDH system set up in 2011. Installed on the roof of the boiler house, it preheats water for a wood chip boiler in the district heating station of Dūkštas, a town in eastern Lithuania. The demonstration unit with 82 m² of vacuum tube collectors received funding from international organisations.

Denmark: Concentrating Solar Collectors for District Heat in Northern Europe

Submitted by Baerbel Epp on August 11, 2017
BronderslevBrønderslev, a Danish municipality with a population of 12,500, is setting up a multi-purpose renewable heat plant for their district heating network. So far, local utility Brønderslev Forsyning has been operating seven gas-fired combined heat and power (CHP) plants and two gas boilers to produce 130 GWh of heat each year. In the future, most of the yearly district heating demand is planned to be met by a new Organic Rankine Cycle (ORC) unit which receives its energy from two wood chip boilers with 10 MW each and from a 16.6 MWth parabolic trough collector field with a mirror area of 27,000 m².

Solar Thermal Shows Highest Energy Yield Per Square Metre

Submitted by Baerbel Epp on July 31, 2017
Area Yield ComparisonThe annual energy yield per square metre is much higher for solar collectors than for other renewable technologies, as the figure on the left shows. Compared to PV, solar collectors produce, on average, three times as many kilowatt-hours. Compared to biomass or bioethanol, output is in average as much as 43 times their yield. The chart shows end energy production and compares directly thermal and electric kilowatt-hours. The grey part of each bar marks the deviation in yield based on different estimates. The absolute values can be found in a table at the bottom of this article.

Egypt and Jordan: SHAMCI to Give New Impetus to Arab Markets

Submitted by Baerbel Epp on July 13, 2017
SHAMCI Workshop May 2017The implementation of SHAMCI, the Solar Heating Arab Mark and Certification Initiative, could help expand the solar thermal market in both Egypt and Jordan. On 15 and 16 May 2017, a workshop held at the headquarters of RCREEE (Regional Center for Renewable Energy and Energy Efficiency) and on the premises of NREA (New and Renewable Energy Authority of Egypt) in Cairo offered experts, market observers and stakeholders from both countries a platform to discuss requirements for implementing SHAMCI at national level. Solarthermalworld.org spoke to Lotus Shaheen, who works at SHAMCI’s secretariat, about the results of the workshop and the next steps by the regional initiative.
