French Independent Heat Supplier: “Optimise and de-risk all contracts”

Submitted by Baerbel Epp on August 17, 2017
French-based NewHeat is a rapidly growing start-up. About two years after it was founded in December 2015, management has raised almost EUR 1.8 million from private investors to finance the first solar heat delivery projects and strengthen its global sales force. NewHeat, headquartered in Bordeaux, France, calls itself an independent integrated solar heat producer aiming at end customers in district heating and industry. The company is also an industry member of Task 55 of the IEA Solar Heating and Cooling programme, Towards the Integration of Large SHC Systems into DHC Networks. CEO Hugues Defréville (left photo) and CTO Pierre Delmas not only established the start-up two years ago, but have knowledge and skills that complement each other to advance the business.

IEA SHC: Coordinating Thermal Energy Storage Research Worldwide

Submitted by Baerbel Epp on August 30, 2016
The key to the decarbonisation of the energy sector is new compact storage technology: It will require much R&D to develop market-ready products based on new storage designs with phase change and thermochemical materials (PCMs and TCMs). One strategy is to combine resources within international research programmes – to create platforms unhindered by national borders or scientific disciplines, such as the joint task Material and Component Development for Thermal Energy Storage planned within the IEA Technology Collaboration Programmes. Its two future operating agents, Wim van Helden (left) from Austrian AEE INTEC for the IEA Solar Heating and Cooling Programme and Andreas Hauer from the German Bavarian Center for Applied Energy Research (ZAE Bayern) for the IEA Energy Conservation through Energy Storage (ECES) programme, invite all interested researchers to Vienna, Austria, to attend the second Task Definition Meeting on 15 and 16 September 2016. 

IEA SHC: Reaching 40 Years of Global Research Activities

Submitted by Baerbel Epp on January 28, 2016

The International Energy Agency (IEA) wants to strengthen its work supporting the energy transformation to a safe and sustainable low-carbon energy system. A key asset of the IEA is its global network of over 6,000 energy technology researchers and experts working in the 39 Technology Collaboration Programmes, TCPs, (former Implementation Agreements) on a broad range of energy subjects. "We are on the verge of a new era of energy system transformation and innovation", said Alicia Mignone, Chair of IEA Committee on Energy Research and Technology (CERT) during a stakeholder meeting in September 2015 to celebrate the 40th anniversary of the TCPs. "We need to take full opportunity of these amazing instruments that are the IEA TCPs to ensure that the IEA remains at the forefront of global energy technology analysis." The Solar Heating and Cooling Programme (IEA SHC) is one of the 10 renewable TCPs. There are TCPs as well in the field of Fusion Power, Fossil Fuels and Energy End-Use Technologies (see attached pdf with a full list of TCP topics).

France: Promising Monitoring Results of Solar-Cooling Hybrid Strategy

Submitted by Baerbel Epp on November 5, 2014
Hybrid Solar Cooling ConceptDuring the Task 48 meeting in Garching, Germany, at the end of September 2014, Daniel Mugnier, Head of Task 48 of the IEA Solar Heating and Cooling programme, presented the monitoring results of a promising demonstration project which integrates solar cooling technology into an existing building cluster. Engineered by Tecsol, the system has been supplying energy to two buildings housing offices and flats in Montpellier, in the south of France, since May 2012. The special characteristic of the system owned by the SERM (Société d’Équipement de la Région Montpelliéraine) is a hybrid mode in which the 240 m2 field with double-glazed collectors supplies heat to a single-effect lithium-bromide absorption chiller in summer, as well as domestic hot water to the block of flats all year round. During the main cooling season in July and August, the electrical coefficient of performance (COP) showed a very high average of 12, while the measured thermal COP during the same period was, on average, 0.6.

Sweden: Novel Solar Cooling Installation Boasts Average Electrical COP of 10.6

Submitted by Baerbel Epp on October 28, 2014
ConferenceThe first large-scale system which incorporates the newly developed CoolStore chiller by Swedish company ClimateWell was commissioned in June 2014 and has since been operating flawlessly at Swedish coffee producer Löfbergs in Karlstad, Sweden. In the middle of October, ClimateWell organised a mini-conference at Löfbergs in order to showcase the installation and its first monitoring results. The measurements taken between 11 and 25 July showed an average electrical coefficient of performance (COPel) of 10.6. This is more than twice as much as for a conventional electric vapour compression system, which has a COPel of between 2 and 5. The highest COP measured at the demonstration plant was 12.

Switzerland: Process Heat Collector Performance Testing

Submitted by Baerbel Epp on April 1, 2014

Elimar Frank 1Process heat collectors in the range of 100 to 250 °C represent a rather new type of technology, and test institutes are facing some challenges when trying to test these collectors. spoke with Dr Elimar Frank, Research Director at the Swiss Institute for Solar Technology, SPF, in Rapperswil. Frank is also Subtask Leader for Process Heat Collector Development and Process Heat Collector Testing in Task 49 of the IEA Solar Heating and Cooling Programme. The chart shows the efficiency curves of different collector types.

Portugal: Task 49 Develops Process Heat Integration Guidelines

Submitted by Baerbel Epp on December 3, 2013

In the middle of October, the members of the IEA SHC Task 49 on solar process heat met in Évora, Portugal, to discuss, among other things, the first version of the integration guidelines for solar process heat systems. They are part of the design guidelines - one of the main goals of the Task. According to Christoph Brunner, the Task’s members plan to publish the integration guidelines in early 2014 after an internal review. Brunner is Operating Agent of Task 49 and Head of the Department of Industrial Processes and Energy Systems at the Austrian institute AEE Intec.

SHC 2013: “Be transparent about the performance”

Submitted by Baerbel Epp on October 7, 2013

Europe’s first International Conference on Solar Heating and Cooling for Buildings and Industry, the SHC 2013, has been a success. Between 23 and 25 September, around 400 participants from 37 different countries met in Freiburg in the south of Germany to discuss research, technology and market-related issues. This was almost double the number of experts which had joined the first SHC conference last year in San Francisco. The 15 keynote speeches, 90 oral and 140 poster presentations covered a huge variety of topics from engineering and new materials to enhancing already available products.

An exhibition taking place as part of the International Conference on Solar Heating and Cooling (SHC) 2013 between 23 and 25 September 2013 unveiled how solar collectors manufactured from plastic materials may look like in the future. Under the motto Efficiency and Design, the exhibits provided an insight into research trends and product innovations for solar thermal applications. The exhibition was organised by a working group of Task 39, a sub-task of the International Energy Agency’s Solar Heating and Cooling Programme, IEA SHC.

Global Trends in Solar Heat Worldwide 2011 Study

Submitted by Baerbel Epp on August 17, 2013

The Solar Heat Worldwide 2011 report from May 2013 again gathers the latest market figures from 56 countries around the globe, covering 95 % of the world’s solar thermal market, according to the authors from Austrian company AEE Intec. In 2011, installers set up a total capacity of 48.1 GWth - corresponding to 68.7 million m2 of glazed and unglazed solar collectors - in these 56 countries. Solar thermal installations increased by 14.3% compared to 2010. The breakdown by collector type in 2011 is 14.7% glazed flat plate collectors, 81.9 % evacuated tube collectors, 3.2 % unglazed water collectors and 0.2 % air collectors. The chart shows the growth rate of the newly installed flat plate and vacuum tube collector capacity in the major markets in 2010/2011.
