Hybrid concentrated solar power (CSP)-biomass plants in a semiarid region: A strategy for CSP deployment in Brazil

The production of electricity using concentrated solar power (CSP) technology is not yet possible in Brazil due to the technology's high capital costs and the lack of a local industry. However, this study introduces a low-cost approach to CSP in Brazil by describing and simulating the operation of hybrid CSP plants that use sustainably managed biomass in Brazil's semiarid northeast. Biomass hybridisation of a CSP plant with a solar multiple (SM) of 1.2 and a biomass fill fraction (BFF) of 30% can generate electricity at 110. USD/MWh. The high direct normal irradiation (DNI) and the availability of local low-cost biomass in Brazil's semiarid northeast suggest the possibility of developing a CSP industry capable of supplying low-cost components under a national program framework, with the co-benefits of local job and income generation. For example, the deployment of 10 CSP plants of 30. MWe each would generate 760 direct and indirect jobs during the 24 months of plant construction and approximately 2100 annual jobs associated with the operation and maintenance (O&M) of the generating units. These 10 new units would generate additional local income on the order of USD 57 million.
