World Bank Supports Solar Concentrating Solutions for Industry

Submitted by Baerbel Epp on October 23, 2017
Poll ResultsOn 18 October 2017, speakers from three continents joined a webinar initiated by the World Bank and the Clean Technology Fund and hosted by Spanish-based consultancy ATA Insights to talk about opportunities for concentrating solar thermal in industry. Martin Haagen from Industrial Solar, a German-based Fresnel collector manufacturer, analysed solar heat in industry at the macro-level. Rodrigo Mancilla, Executive Director of the Chilean Economic Development Agency, CORFO, gave his thoughts on solar heat in mining, and Eyas Al-Zadjali, Project Development Manager at Glasspoint based in Oman, spoke about the ongoing construction work for Miraah, a plant to generate solar steam for enhanced oil recovery. Additionally, opinion polls during the event asked, for example, what the around 270 participants thought was the best public support mechanism to kick-start concentrating solar thermal deployment (see the screenshot above).
 

Italy: 10,000 m² ORC-Connected Fresnel and Parabolic Trough Fields

Submitted by Baerbel Epp on September 19, 2017
Fresnel Collector Field ItalyItaly’s feed-in tariff for medium-size concentrating solar power plants has supported the installation of a 10,000 m² Fresnel collector array in Sardinia (see photo). The mirrors have been in operation since spring this year and are connected to an Organic Rankine Cycle (ORC) unit with 600 kW of nominal electric power. Construction for a second demonstration system, a 5 MWth parabolic trough field linked to an ORC turbine, is currently underway in Sicily. Both installations heat thermal oil to between 250 and 300 °C and use it to transfer heat directly from the solar panels to the ORC units by Italian-based Turboden, bringing their electrical efficiency to up to 25 %.

China: “There is strong competition between PV and solar thermal cooling”

Submitted by Baerbel Epp on May 24, 2017
YazakiTwo larger solar thermal cooling installations were put into operation in China in 2016. One of them was a 23-kW Yazaki absorption system (left photo) and one a new developed 50-kW variable-effect absorption chiller driven by a Fresnel collector (right). Solarthermalworld.org spoke with Professor Yanjun Dai of Shanghai Jiao Tong University (SJTU) about the market and technological advances of solar cooling in China.

Concentrating Solar Heat in Spain: An Untapped Market

Submitted by Baerbel Epp on January 29, 2016
FresnelLast December, the Spanish Advanced Technology Center for Renewable Energies, CTAER, and the Solar Concentra forum in Spain released a study which evaluated the potential of medium- and low-temperature solar thermal concentration technologies across Spain (between 100 and 400 °C). The study, entitled Applications and market potential of medium-temperature concentrating solar power technologies in Spain, concludes that these technologies have already been cost-competitive with some alternatives, such as oil and gas, in the industrial and residential segments, and it provides some recommendations to promote this promising market. The photo shows one of the very few solar process heat installations in Spain with concentrating technology. It is a pilot plant with a Fresnel collector which has been supplying the animal feed production unit of Spanish company Grasas del Guadalquivir in Cordoba since in March 2015.

Italy: Solar Steam for Cheese Production

Submitted by Baerbel Epp on July 24, 2015
CSP San NicoloDirect steam production, 50,000 litres of diesel saved per year and the advantage of the Italian incentive scheme for renewable heat: All these favourable conditions allowed a small dairy in Sardinia to choose a concentrated solar thermal plant with Fresnel collectors for generating 200 °C steam. The steam is used to supply heat to the industrial processes for cheese production. The investment of EUR 400,000 will have a payback period of about 4 years.

Webinar: New Business Models for Commercial Solar Thermal Applications

Submitted by Baerbel Epp on June 29, 2015
Webinar ISESThe solar thermal industry is facing a great challenge in entering new commercial solar thermal markets, be it tourism, solar process heat or large solar district heating. It needs new business models to convince commercial customers to use or to invest in solar thermal. A webinar jointly organised by International Solar Energy Society (ISES) and solarthermalworld.org on 23 June 2015 thoroughly analysed the current situation during presentations by the International Renewable Energy Agency (IRENA) and three turnkey system suppliers: Industrial Solar, Germany, S.O.L.I.D., Austria, and Nextility, USA (find all four presentations attached to this news article). One thing to take away from the webinar was: Financing is a crucial bottleneck for large-scale turnkey system suppliers.
 

Jordan: Fresnel Collectors Supply 160 °C Steam to Pharmaceuticals Producer Ram Pharma

Submitted by Baerbel Epp on May 26, 2015
The Jordan Minister of Environment, Dr Taher Shakhshir, inaugurated the first solar steam system in Jordan on 17 May 2015. The Fresnel collector plant was set up on the roof of pharmaceuticals producer Ram Pharma, located at the Abdullah II Ibn Al-Hussein Industrial Estate about 15 km away from Amman, Jordan’s capital. The concentrating Fresnel collectors manufactured by Industrial Solar, Germany, supply steam at 160 °C to the factory’s steam grid, which provides the energy needed for sterilisation, drying and fermenting. Solar energy is said to save around 30 % of the annual diesel demand for Ram Pharma processes.

Germany: Excel-Based IRR Commercial Project Calculations

Submitted by Baerbel Epp on September 25, 2014
IRR cash flow diagrammeGerman Fresnel collector manufacturer Industrial Solar is experiencing an increasing demand from clients all around the world: “Five years ago, we received two requests per month. Now, we receive around 50 each month and the requests are more serious,” Tobias Schwind, who is one of the Managing Directors of the company founded in 2009, confirms. Schwind has begun to notice a shift in the industry: “Whereas payback times of three to four years have, so far, been commonplace, the industry is steering towards five- to six-year periods,” he says and adds: “We, however, try to explain to our clients that they are investing in their infrastructure, and payback time is therefore not really the best criterion.” Industrial Solar offers potential clients a calculation of the Net Present Value (NPV) and the Internal Rate of Return (IRR). According to the managing director, an economic analysis based on these parameters often shows that solar process heat is worth further consideration.
 

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.

Germany: World Map of Solar Process Heat Collector Industry 2014

Submitted by Baerbel Epp on March 31, 2014
World Map Process HeatThere is enormous demand for industrial heat in the temperature range between 100 and 250 °C all around the world, and solar thermal technologies are said to play an important role in covering this demand over the next decades. A joint project by magazine Sun & Wind Energy and German agency solrico was to find out which companies offer solar process heat collectors, what technology they focus on and how many commercial projects they have already realised. The results of the global survey now make up the first World Map of the Solar Process Heat Collector Industry, which was published in the March edition of Sun & Wind Energy and is also available for download on solrico´s website
