SOCRATCES | SOlar Calcium-looping integRAtion for Thermo-Chemical Energy Storage

Summary
Lime (CaO) has been long proposed as an energy-intensive material for the storage of energy in a chemical form by means of carbonation/calcination cycles. This Calcium-looping process (CaL) is the basis of a proven pilot-scale technology for CO2 capture, which is accomplished by carbonation of CaO and its regeneration in a calciner reactor operated under high CO2 partial pressure and high temperature. The wide availability of limestone (45%) are achieved under new CaL conditions implying carbonation under high temperature (>850ºC) at high CO2 partial pressure compatible with high-efficiency power blocks. Moreover, fast calcination is carried out at temperatures < 700ºC by the Flash Calcination technology, which allows using mature and inexpensive solar receiver technology. Circulating Fluidized Bed reactors of proven efficiency. The new CSP-CaL integration yields high storage energy density (3.2 GJ/m3) with possible long-time gaps between load and discharge. SOCRATCES is aimed at demonstrating the feasibility of this integration by erecting a pilot-scale plant that uses cheap, abundant, and non-toxic materials as well as mature solar and fluidized bed reactor technologies. SOCRATCES will confer the EU a leading role in the development of efficient and non-toxic CSP with low-cost storage (
