Hydrogen production from the co-utilisation of coal and biomass

Fermoso Domínguez, Javier ; Arias Rozada, Borja ; Pevida García, Covadonga ; González Plaza, Marta ; Rubiera González, Fernando

In this work, co-gasification and co-pyrolysis of binary blends of a bituminous coal (PT) and two types of biomass (olive stones, OS; chestnut, CH) were conducted at atmospheric pressure in a fixed bed reactor. Pyrolysis was performed under nitrogen, and gasification under steam/oxygen atmosphere. I...

Resumen en español Se evalúa económicamente la utilización de la tecnología de gasificación de carbón en la generación de energía eléctrica, utilizando información secundaria y el enfoque de valoración de opciones reales mediante árboles binomiales de 2 variables. Se analiza el caso de adaptar una central existente de gas natural de ciclo combinado (NGCC) para la utilización de syngas a partir de carbón; en un segundo caso, se evalúa la instalación de una nueva central termo (mas) eléctrica de carbón pulverizado (PC) o alternativamente una central de gasificación de carbón integrada a ciclo combinado (IGCC). En este último caso, se evalúa la opción de "switching" de combustible. Para los precios de los combustibles se emplean modelos de Movimiento Browniano Geométrico No Homogéneo (IGBM) y en ambos casos estudiados se analiza en 2 escenarios de precios, incluyendo análisis de sensibilidad. Respecto al primer caso, la adaptación a syngas de una planta NGCC es conveniente económicamente, teniendo el proyecto una alta sensibilidad respecto a la eficiencia. La sensibilidad a la inversión no es significativa, como tampoco a los gastos de operación. Respecto al segundo caso, la conveniencia económica de la planta IGCC frente a la planta PC no es clara en los escenarios de precios considerados. Pero analizada en diversas combinaciones de precios, la planta IGCC de operación flexible alternando dos combustibles puede lograr ventajas económicas. Respecto a la sensibilidad, se repiten las conclusiones mencionadas para el primer caso Resumen en inglés The use of coal gasification technology in the generation of electric power is evaluated economically. Secondary information and valuation of real options approach is used, with two variables binomial lattices. First, the retrofit of an existing natural gas combined cycle plant (NGCC) for the utilization of syngas from coal is analyzed; on the second case, an economical evaluation is realized for to compare a new Pulverized Coal plant (PC) and, alternatively, an Integrate (mas) d Gasification to Combined Cycle plant (IGCC). In this last case, the fuel switching option of the IGCC plant is analyzed. For the fuel prices, Inhomogeneous Geometric Brownian Movement processes are used. In both cases, two prices scenarios are considered with sensitivity analysis. Regarding the first case, adaptation to syngas in a NGCC plant is economically desirable, having the project a high sensitivity to efficiency. The sensitivity about investment is not significant, nor to the operating expenses. Concerning the second case, the economic convenience of the IGCC plant in front of the PC plant is not clear in the price scenarios considered. But analyzed in various combinations of prices, flexible operating IGCC plant alternating two fuels can achieve economic advantages. With regard to the sensitivity, conclusions mentioned in the first case are similars for the second case
