Abstract

The environmental and geopolitical concerns encourage governments towards the utilization of renewable energy sources (RES). Finding CO2 zero/near-zero power production techniques is imperative. Biomass, a carbon neutral fuel, can be used in Joule-Bryton power cycle; however, this will require novel strategies to adapt the gas turbine proven techniques to biomass utilization. In this work, we evaluate two possible alternatives to use biomass in modern gas turbines and the perspectives for their implementation within the Colombian context: First, the indirect fired gas turbine which allows a wide variety of fuels and simple operation. Second, low heating value fuel gas turbines could use gasified biomass and maintain high levels of single cycle efficiency, although a previous gasification stage is required. In terms of technology, the comparison is done using a single cycle 18MWel engine. Technical parameters, as total fuel consumption, total cycle efficiency, heat rate, maintenance intervals, and replacement cost of vital components are considered. In terms of implementation, the analysis focuses on potential policy instruments that promote the deployment of these technologies in Colombia. Thus, the study provides the basis for further analysis of biomass-based gas turbines in other Latin American countries with similar realities. Economical key parameters are estimated.
