Накратко на български
Разтопено стъкло, получено от пясък, се изследва като материал за съхранение на топлинна енергия при температури над 700 °C в слънчеви централи. Това помага за намаляване на разходите и осигуряване на електричество дори през нощта или при облачно време.

Innovative high temperature thermal energy storage concept for CSP plants exceeding 50% efficiency
Energy provision is a big challenge for our Society, being the present production/consumption paradigm not sustainable. To change current trends, a large increase in the share of Renewable Energy Sources (RESs) is crucial. The evolution towards a society not based on fossil fuels has become a matter of the greatest interest, and solar energy has the potential of providing 27% of global electricity in 2050 – above all others RESs – of which around 11% from Concentrated Solar Power (CSP). CSP systems have the distinctive ability of providing dispatchable power: State-of-the-Art (SoA) CSP plants featuring Thermal Energy Storage (TES) run overnight or with cloudy sky, providing renewable base–load generation and ancillary services aiding the penetration of intermittent sources such as wind and solar PV. Still, deployment lags behind expectations and technology breakthroughs are needed in order to significantly reduce costs. Most notably, TES options working at temperatures exceeding 700 C still need to be developed. GLASUNTES aims at bridging this gap by achieving three main objectives, i.e., to prove the feasibility and assess the potential of 1. an innovative CSP concept whereby (i) the receiver is co-located with the TES vessel, and (ii) the solar radiation is directly absorbed by the liquid storage medium; 2. the adoption of common glass-forming compounds as novel TES materials. These are nontoxic and inexpensive (mainly sand), and the related know-how is already available from the glass manufacturing field; 3. the CSP systems resulting from the integration between receiver–TES and recently proposed high-performance power conversion units based on supercritical CO2 thermodynamic cycles. The project successfully demonstrated that common glass in molten state can be effectively use to directly capture and store concentrated solar energy at temperature above 1000 C. During the experimental campaign glass temperatures as high as 1300 C were reached.

Цел на проекта
Energy provision is a big challenge for our Society, being the present production/consumption paradigm not sustainable. To change current trends, a large increase in the share of Renewable Energy Sources (RESs) is crucial. The effectiveness of Thermal Energy Storage (TES) poses Concentrated Solar Power (CSP) systems at the forefront, as the first dispatchable option among all intermittent RESs. In order to realize the CSP potential, the efficiency of the adopted Power Conversion Units (PCUs) must grow over 50%, entailing temperature levels of the order of 1000 °C: promising solutions are based on Brayton thermodynamic cycles. This project stems from the observation that no existing TES option can be coupled to such PCUs and/or work at these temperatures, and aims at filling this gap. Three interrelated research objectives are proposed, to prove the feasibility and assess the potential of1. an innovative CSP concept whereby (i) the receiver is co-located with the TES vessel, (ii)the solar radiation is directly absorbed by the liquid storage medium, and (iii) the thermalpower is withdrawn from the TES by bubbling a gas through it, which can thus be used asworking fluid in a Brayton cycle. An efficient and simple system results, without irradiatedmetal tubes, secondary fluid loops, heat exchangers, valves, nor pumps;2. the adoption of common glass-forming compounds as novel TES materials. These are nontoxicand inexpensive (mainly sand), and the related know-how is already available fromthe glass manufacturing field, whose deep synergies with the CSP sector will be exploredin a multi-disciplinary perspective;3. the CSP systems resulting from the integration between receiver–TES and PCUs.The envisaged approach combines advanced theoretical and experimental research activities to achieve these goals. The final scope is to inaugurate a new branch in the field of solar systems, with the potential of enabling the CSP plants we need to ensure a bright Future.
