Original project consortium - From Section 1 2
Present project consortium 3
Project aims and objectives From Section 5 Aims General objectives 1. Slag as effective thermal storage material from the physical chemical point of view; 2. Versatility of slag with respect to HTF and storage tank materials; 3. Technical viability of heat storage systems based on different slag configurations; 4. Economical and ecological viability of slag as HSM; 5. Slag as ideal material for thermal storage in CSP applications with high solar concentration (T up to 1000 ºC). 4
Scientific, technological and commercial objectives From Section 6 Scientific objectives 1. Determination and explanation of the physical and chemical properties of slag; 2. Understanding of the thermocline phenomenon and its use in TES. Technological objectives 1. Release of a complete fact sheet on slag by also including compatibility with different materials; 2. Slag moulding processes to obtain slag objects with different shapes; 3. Heat storage units with different slag object configurations Commercial objectives 1. Cheap heat storage systems as compared to 2 tanks molten salt thermal storage systems. 5
The three slag configurations considered in the original project From Section 8 TES systems based on slag use As-received slags Multi modules Single module Configuration A Configuration B Configuration C Shaped slags Tank Slags Air TES testing Random packed bed Made by moulding Block with multiple tunnels Honeycomb structure Made by extrusion 6
The basic innovative concept: Thermocline TES systems with solid materials in packed bed configurations Advantages: Direct contact between the fluid (air, salt, oil etc.) and the storage material: No heat exchanger needed! Different solid materials with potential application: Valorization of industrial by products as TES material. Cost effective storage concepts (Thermocline based). High temperature storage (Up to 1200 ºC). Potential applications: CSP storage units: Single tank high solution Industrial heat recovery: High temperature heat recovery in steel, glass, ceramic, foundry industry 7

Remarks and suggestions - I Time history of the project DATE MONTH NUMBER ACTION 15 May 2013 0 First presentation of the proposal to SOLAR-ERA.NET 5 June 2013 1 SOLAR-ERA.NET invitation to present the full proposal 9 October 2013 5 Submission of the full proposal to SOLAR-ERA.NET 4 December 2013 7 SOLAR-ERA.NET communication of the proposal eligibility to financial support 31 March 2014 10 Submission of the full proposal to the Spanish call of MINECO 11 July 2014 14 MINECO communication of the proposal eligibility to financial support 20 April 2015 23 Kickoff meeting of the project Reasons behind the long time history The main reason is the lack of coordination between all the involved national supporting agencies Consequences of the long time history Requests to shift the deadline of the project to align all the national approvals of the project Appearance of other studies on similar topics and/or applications (with partial loss of motivations) Negative interference with other EU calls, mainly H2020 calls, with higher TRL 10

Remarks and suggestions - III General suggestions to improve SOLAR_ERA.NET SOLAR ERA.NET has to request to the national supporting agencies a faster answer SOLAR ERA.NET has to request to the national agencies a more uniform behaviour concerning the percentage of financial support Since H2020 is more focused on projects with a high TRL, SOLAR ERA.NET has to keep or, better, to increase the support to basic projects up to TRL 3 4 12
