Published at Journal of Energy Storage – The cost-competitiveness of concentrated solar power with thermal energy storage in power systems with high solar penetration levels

Abstract: In this paper, we show that concentrated solar power (CSP) with thermal storage is an economically attractive technology to achieve high solar penetration levels. To this end, we utilize an alternative framework of net levelized cost of electricity (net-LCOE), which captures the projected curtailment rate, to economically compare PV with batteries to CSP in …

Synthesis and Structural Study of Substituted Ternary Nitrides for Ammonia Production.pdf Abstract: Over the past few decades, inorganic nitride materials have grown in importance in part due to their potential as catalysts for the synthesis of NH3, a key ingredient in fertilizer and precursor to industrial chemicals. Of particular interest are the ternary (ABN) or …

Published at Applied Energy – Co-optimisation of the heliostat field and receiver for concentrated solar power plants

Abstract: In a concentrated solar power (CSP) tower plant, it is essential to understand the performance of the subsystem formed by the heliostat field and the receiver, operated with an optimal aiming strategy that guarantees the safety and lifetime of the receiver while maximising performance. State-of-the-art studies optimise the heliostat field, aiming strategy and the …

Published at Energy – Concentrating efficiency loss of heliostat with multiple sub-mirrors under wind loads

Heliostats in a Tower CSP project IMAGE@GrupoCobra Abstract: As an important design load for heliostat, wind load crucially affects the safety and concentrating performance. Herein, an evaluation method is proposed to study the impacts of wind loads on concentrating efficiency loss of the heliostat with multiple sub-mirrors. In particular, the computation method and evaluation index …
