Biomass Resources to Hybridize CSP with Biomethane: Potential of Horticultural Residues and Drought-tolerant Crops.

摘要

HYSOL technology allows the hybridization of Concentrated Solar Power (CSP) technology with biomethane for the efficient generation of clean and sustainable electricity in a firm and dispatchable manner. Biomass from horticultural residues and drought-tolerant crops is a promising feedstock for biomethane production in areas with high solar radiation. This paper investigates the biomass potential of these two resources in Spain by considering the volume of horticultural residues generated, availability of suitable land for dedicated prickly pear plantations and its methane generation capacity. Experimental biomethane yields have also been determined for different substrates mixtures of overripe tomatoes and prickly pear cladodes. Potential biomethane and electricity production are then calculated, as well as the number of conventional CSP and HYSOL plants that could be supplied with this energy. Results show that a significant number of CSP plant could be methane-supplied by the studied resources: up to 45 conventional CSP or 4 HYSOL plants.
