“…Biowaste conversion to biogas is modelled considering a system expansion approach as recommended by ISO 14040-14044. Thus, the biomethane life cycle takes into consideration savings in the emission of CH 4 and N 2 O, avoiding conventional biowaste treatment (storage in an uncovered tank before field application as fertilizer), as described by Giuntoli et al [23].…”

“…To this purpose, a research project titled HYSOL (funded by the European Commission under its 7th Framework Program) is developing and testing a new hybrid configuration for CSP plants intended to achieve higher energy efficiency, reduced economic costs, and improved firmness and dispatchability in the generation of power on demand. Furthermore, HYSOL plants may operate using biomethane as auxiliary fuel, resulting in the generation of 100% renewable electricity [4,5].…”

Concentrating Solar Power (CSP) technology is developing in order to achieve higher energy efficiency, reduced economic costs, and improved firmness and dispatchability in the generation of power on demand. To this purpose, a research project titled HYSOL has developed a new power plant, consisting of a combined cycle configuration with a 100 MWe steam turbine and an 80 MWe gas-fed turbine with biomethane. Technological developments must be supported by the identification, quantification, and evaluation of the environmental impacts produced. The aim of this paper is to evaluate the environmental performance of a CSP plant based on HYSOL technology using a Life Cycle Assessment (LCA) methodology while considering different locations. The scenarios investigated include different geographic locations (Spain, Chile, Kingdom of Saudi Arabia, Mexico, and South Africa), an alternative modelling procedure for biomethane, and the use of natural gas as an alternative fuel. Results indicate that the geographic location has a significant influence on the environmental profile of the HYSOL CSP plant. The results obtained for the HYSOL configuration located in different countries presented significant differences (between 35% and 43%, depending on the category), especially in climate change and water stress categories. The differences are mainly attributable to the local availability of solar and water resources and composition of the national electricity mix. In addition, HYSOL technology performs significantly better when hybridizing with biomethane instead of natural gas. This evidence is particularly relevant in the climate change category, where biomethane hybridization emits 27.9-45.9 kg CO 2 eq per MWh (depending on the biomethane modelling scenario) and natural gas scenario emits 264 kg CO 2 eq/MWh.

Molten salt thermal storage systems are the keystone of the dispatchability of demand in solar thermal power plants and many commercial plants use this technology. Nevertheless, there are still open questions related to long-term durability and reliability of components. During experimental campaigns in the CIEMAT-PSA molten salt testing facility, a performance detriment in a multi-pass shell-and-tube heat exchanger was noticed. For this reason and as a tool for analysis and diagnosis, an object-oriented dynamic model is being developed. This paper describes the testing facility and the thermal oil -molten salt heat exchanger particularly, the design of the Modelica model and compares simulation results against manufacturer calculations and experimental data in steady-state operation conditions and at transients in order to evaluate the heat exchanger performance.

“…A fairer performance ratio and a comparatively lower natural gas usage are achievable, for what reason this idea is increasingly studied in the last years (e.g. Turchi et al 2011;Vogel et al 2013;Servert et al 2014). …”
