Solicitation Objectives

The Funding Opportunity Announcement identifies and supports long-termresearch and development (R&D) activities and near-term demonstration in twoareas that may increase the efficiency and reduce the cost of concentrating solarpower (CSP) systems to make them cost competitive:

1. Improved Heat Transfer Fluids (Advanced HTF) Identify and characterize novel fluids or fluid types that possess the

physical and chemical properties required for an improved HTF and

thermal storage fluid for CSP technologies

2. Novel Thermal Energy Storage Concepts (Novel TES Systems) Generate and evaluate novel concepts for thermal energy storage (TES)

that have the potential to reduce the cost of TES to less than $15/kWthermaland achieve round trip efficiencies greater than 93%.

Work in TES may be applicable to any or all CSP technologies (parabolictrough, power tower, linear Fresnel, or concentrating dish)
