Falling Particle Receiver, The Latest In CSP Generation.

A 200 feet tall tower developed by Sandia’s National Solar Thermal Test Facility in New Mexico, is the latest technology in concentrating solar power (CSP) systems.

Sandia’s falling particle receiver drops minute sand-like ceramic particles through a concentrated beam of sunlight, where the heated particles are captured and stored in an insulated tank. Unlike standard molten salt systems, this technology can store heat at high temperatures without breaking down. The operating temperature of their falling particle receiver can also exceed 1000°C , unlike molten salt systems limited to up to 600 °C. Thus, more thermal energy can be stored at cheaper storage costs.

Testing of the receiver is still ongoing and is expected to finish at the end of 2015, following which development of a prototype will begin. The prototype will be developed with the goal of creating a cost-competitive falling particle receiver that can receive thermal efficiency of over 90% and achieve particle temperatures no less than 700 °C.

Product Development: Embracing product safety and compliance

PRODUCT DEVELOPMENT: EMBRACING PRODUCT SAFETY AND COMPLIANCE Recent safety incidents on storage plants have raised concerns about the fire safety of battery storage systems. Such events are extremely rare compared to the cumulated global deployments of energy storage systems, which have reached more than 27 GWh by end of 2020 (Wood Mackenzie 2021). However, for…

Energy Storage Systems: the role of an Integrator

Simplifying BESS deployments by mastering their associated risks With the introduction of Battery Energy Storage Systems ‘BESS’, a new role has been created on the value chain. It is the role of a BESS integrator. The role of an integrator can be misunderstood at times or blended with other roles at other times. This is…
