Using solar heat for industrial processes isn’t a new concept and with advancements in CSP technology, new opportunities are being presented. From aiding in the high temperature oil extraction process to low temperature food processing, the application of CSP in industry is providing unique opportunities and, of course, challenges. In this interview, Cédric Philibert of the IEA talks about CSP in industry and reveals these opportunities and barriers.

L.N. What areas of industrial application are starting to experience an impact?

C.P.  So far, non-concentrating solar technologies have dominated industrial applications, with the bulk being in low temperature heat which is basically food and drink.

You can see CSP technology in sectors where you need higher temperature levels. There are several applications, mostly in industries such as food and drink, pharmaceuticals, and textiles.

You also have some in extractive industries. For example, the enhanced-oil-recovery (EOR) project by Glasspoint in Oman. They have adapted CSP to local conditions by using a greenhouse to protect the parabolic troughs from wind and sand. The greenhouse allows for a nightly roof cleaning and the use of lighter troughs. The steam produced is pumped into wells to extract larger quantities of oil.

L.N. In what fields do you think CSP could have the biggest impact in terms of industrial applications?

C.P.  There are two big areas: the extractive industries like oil, gas and mining and food processing. Both industries are usually remote, which drives up the cost of obtaining fuel and which usually means that they have available space for the installation of CSP troughs or towers.

However, the higher the temperature, the more difficult it is for solar to compete with fossil fuels. Efficiently reaching higher temperatures using CSP requires a more complex and well-built system, resulting in a higher cost. Furthermore, fuel is burnt at very high temperatures which means that burning fuel to meet low temperature demands is a bit of a waste, giving CSP more of an advantage in the low temperature range than in the high temperature range.

 

L.N. What are the main barriers for CSP in industrial applications?

C.P.  Space is a barrier for sure. The others are cost and uncertainty. CSP has a different financing structure which requires all investments and costs upfront and you need 15-20 years to make a profit. However, mining companies are reluctant to sign a contract beyond five years because they only have visibility for the next few years (except for diamond mining) due to fluctuations in the market value of the commodities they produce. This makes it very difficult for them to get equipped with renewables which are only profitable if the industry or plant lasts 15-20 years.

PV developers have developed an offer of five years for the mining industry which is doable. The material is light enough that it can be reused in different places if the plant is closed, but this is difficult with CSP technologies. So yes, uncertainty over returns in volatile commodity markets is a real barrier.

L.N. How would you say these barriers can be overcome?

C.P.  Space is probably the most difficult to overcome.  We may see the relocation of industries over time to areas where you have good conditions, such as abundant sunshine and ample space.

Learning, economies of scale and moving to places where the resources and cost of capital are more favorable are very important dimensions in terms of overcoming the barrier of cost. Everything that can help de-risk the investment could lower the cost of capital and therefore reduce the total cost.

Additionally, governments can provide support to jump start the industry and reduce costs. France, for example, offers government funding to invest in process heat.

Lastly, an increase in the cost of burning fuels such as a carbon tax or an emissions trading scheme could help as well.

L.N. You’ve mentioned that parabolic trough is one of the CSP technologies that is being used in industrial processes. What CSP technologies are best suited for industrial applications?

C.P.  The best solar heat technology depends on what temperature is needed for a certain process. You have three different categories of temperature: low which is up to 150° C, medium-high which is between 150-500° C and high which is above 500° C. If you look at industry needs, you will have a big chunk of low temperature industrial processes are mostly done by flat plates or evacuated tubes. Troughs work very well for medium-high temperature needs. For temperatures above 500° C, which represents half the total need, you would use towers or ovens. It needs to be point-focus concentration to efficiently collect energy at high temperatures.

 

L.N In your professional opinion, what does the future hold for advancements of CSP and industrial application?

C.P.  I see significant potential. Unlike space heating, which is difficult because of its inter-seasonal liabilities, industry has year-round energy needs and you make significant savings in the summer.

I see a future for CSP especially in medium temperature levels whereas it’s not yet economically viable for high temperature levels.

Executive Summary. Estudio geolocalizado del potencial de aplicaciones de calor solar de proceso en media temperatura

Along the last decade, the potential use of Solar Heat for Industrial Processes (SHIP) has been studied from different perspectives. However, the scope of these diverse studies has usually been more focused on the technical adequacy dimension considering temperatures, pressure and demand profiles. Despite of the fact of the relevance of either solar irradiation, availability of low cost fossil fuel, or surface availability, these variables have been either usually taken into account by a statistical approach or they have not been considered. The detailed analysis of these variables leads to a case by case approach for each industry, which might be considered as not feasible/practical due to the large amount of different industries in Spain.

This study has reduced the target industrial companies to a sufficient low figure that enables the case by case analysis of their own potential. For enabling this approach, it has been necessary to go deeper in terms of resolution. Previous studies stopped at province detail resolution, so that this study has moved a step further up to municipality resolution.

At municipality resolution, three filters have been applied for identifying those places with higher chances to implement SHIP solutions within 4 strategic sectors (Food & Beverage, Agriculture and Cattle raising, Paper and Textile). These three filters are: solar irradiation, availability of piped natural gas and energy demand profiles. In order to take advantage of synergies with previous studies, these 4 sectors have already been selected as the ones with the higher potential of implementing solar heat for industrial processes (SHIP) projects.

The solar irradiation filter is key as the higher the solar irradiation, the higher the solar heat production will be. There are several available solar irradiation studies in Spain, however none of them, based on author’s knowledge, breaks down the solar irradiance by municipality. The source of information for calculating the solar irradiance per municipality has been the information released by the Project named ADRASE conducted by the CIEMAT. A solar irradiation base line has been set in order to consider the sunniest municipalities in Spain.

The competitor of SHIP projects is the current fuel that the industry is using for heat generation. If the current fuel cost is low, the return on investment period of SHIP projects increases, therefore SHIP projects become less appealing for the industry. Nowadays, the piped natural gas supply is the cheapest energy source for heat production. Besides it’s widespread in Spain. As a working tool for the study, a database showing the current gas infrastructure in all municipalities in Spain, has been built up. Coming back to the study outcomes, those municipalities that have piped natural gas infrastructure online have not been analyzed, as most likely, the industries located in such locations will have a current cheap solution for heat generation. So that, the municipalities that have been the focus of the study are those that do not have piped natural gas infrastructure.

The third filter has been used for selecting the municipalities that have industries of the already chosen sectors (Food & Beverage, Agriculture and Cattle raising, Paper and Textile). For this purpose, the INE (Instituto Nacional de Estadítsica) database and the MINETUR (Ministerio de Energía, Turismo y Agenda Digital) database have been deeply analyzed at municipality resolution.

Once the abovementioned filters have been applied, it’s granted that the non-excluded municipalities meet the following features: solar irradiation is likely to be high, there is not piped natural gas infrastructure, and there are industries of the selected strategic sectors. This procedure leads to a reduced number of municipalities which enables the detailed analysis of each of them. Then, a list of all the companies of each municipality have been created. The next step has been to select those firms with the CNAE code matching with the 4 strategic sectors. Furthermore, for each industrial company the following variables are know: name of the company, activity, location and size (micro, small, medium, big).

Among the whole list, the micro firms have been excluded as most likely these firms are local shops for either selling or distribution purposes, so that they are not manufacturing plants. Based on each firm activity, those that do not have thermal processes (for instance: storage activity) have been also excluded from the list. Eventually, among the non-excluded listed firms, a visual check through google maps has been carried out for evaluating the surface availability on their roofs.

The above-mentioned process has generated a list of 200 industrial companies where most likely the use of solar energy may be a very interesting solution for industrial energy savings using renewables source of energy. The very last step of the study has been to validate the assumptions that have been considered in the methodology. For this purpose, some meetings have been arranged with the selected industrial firms. These meetings have had the goal of sharing the potential benefits of using solar energy in industrial processes between 100ºC up to 400ºC. Additionally, the meetings have been the final cross-check of the methodology carried out in the study with the current real situation of the interviewed industrial companies.

Once the assumptions used for the selected industrial companies list creation have been validated, the outcome of the study is a visual representation of several maps showing Spanish areas with higher density of industries with a high potential of integrating solar energy for medium range temperature processes among one of their existing industrial processes.

Extremadura promueve la energía termosolar para uso agroindustrial

La directora general de Industria, Energía y Minas de la Junta de Extremadura, Olga García, ha señalado en Bruselas que su departamento está investigando el uso de la energía solar térmica de media temperatura destinada a usos agroindustriales.

En este sentido, ha explicado que en el sector industrial extremeño hay una “importante” demanda térmica, por lo que sería “una tecnología idónea para este sector”.

Además, ha añadido que existe un gran potencial de investigación en este ámbito en Extremadura, de hecho, “ya hay algunos proyectos que han comenzado a desarrollar prototipos de colectores solares de media temperatura”.

Esta iniciativa ha sido expuesta este martes por la directora general autonómica de Industria, Energía y Minas durante su intervención en la Semana Europea de las Regiones y Ciudades 2017; en concreto, en el marco de la Plataforma de Especialización Inteligente de Energía (S3 PEnergy), en la que está incluida la Asociación de Energía Solar que lidera Extremadura desde el pasado mes de mayo.

Como región líder de la Asociación de Energía Solar, Olga García ha expuesto las dos iniciativas en las que está trabajando la Junta de Extremadura.

La investigación en el campo de la energía solar térmica de media temperatura y una primera iniciativa, “mucho más ambiciosa”, expuesta en Helsinki durante la segunda Conferencia de las Regiones Inteligentes, sobre energía termosolar hibridada con fotovoltaica, señala la Junta de Extremadura en nota de prensa.

De este modo, la región de Alentejo se ha sumado al proyecto que tiene un doble objetivo, por un lado la innovación tecnológica, y por otro, la actividad comercial como exportadora de electricidad a países europeos con menor potencial de desarrollo de energía renovable.

Atendiendo a este último, el “objetivo” es lograr “el menor coste posible de producción, entre 6 y 8 cts /KWh”, ha señalado Olga García, quien ha añadido que en Dubi ya se ha conseguido el precio “más bajo de la historia” de la energía solar térmica, con 6 ct/KWh.

“La diferencia entre este coste y el precio pool de la energía, sería asumido bien por las regiones europeas, mediante mecanismos de cooperación, o por entidades privadas con objetivos cien por cien renovables”, ha aseverado la directora general.

Asimismo, Olga García ha destacado el papel de Extremadura como “principal” productora de energía procedente del sol, de tal forma que es la región europea que “más” energía solar instalada produce por habitante, no sólo termosolar sino también fotovoltaica.

La cobertura de la demanda regional de electricidad con energía solar fue del 61 por ciento en el año 2016, ha recordado al respecto.

Concentrated Solar Power Collectors for District Heat in Northern Europe

Compared to steam turbines based on a water circuit, ORC installations make it possible to recover heat from low-temperature sources available in small-capacity plants. An ORC system can work well in concert with biomass combustion and solar concentrating units. The system was named for its use of an organic fluid characterised by high molecular mass and a liquid-vapour phase change at temperatures below water-steam transformation.
The ORC unit in Brønderslev will come from Italian-based Turboden. Turboden has implemented around 300 ORC units all over Europe in recent years, according to a document by DTU, the Technical University of Denmark (see the document attached).
The parabolic trough field was delivered and installed by Danish-based Aalborg CSP. It came online in spring 2017 and has since been feeding into the town’s district heating network. Once the ORC system is put into operation, as is planned for April 2018, solar energy – collected via thermal oil at around 300 °C – is said to be used for fuelling it. “By the end of this July, the collector field will have produced 6,500 MWh, and we expect 16,000 MWh from year-round operation,” said Thorkil Neergaard, Managing Director of Brønderslev Forsyning. This would translate into a specific yield of 594 kWh/m²a. Both biomass systems are said to start producing heat late this year. Neergaard expects gas to be used only during very cold periods and perhaps the units could be stopped during some years completely.
