Abstract
In this article a techno-economic study of an Electric-Biomass on-grid power plant is presented, in order to compare the performance and the operating annual cost under some types of biogas produced from poultry, bovine and porcine manure, and solid urban organic waste, using the Homer® software to develop many solutions. Certainly, the best set up had the maximum combined renewable energy with a minimum electric consumption from the grid. The scheme was integrated by two 500kW biogas-powered electric generator on grid to supply an average energy of 1401.6kW, with an annual operating cost of $2.09 million when the energy supply is electric. Results presented a significant operational cost reduction when the biogas generator is operating on grid, finding an 8.61% of cost decrease using biogas generated from poultry, bovine and porcine manure, and a 10.53% of cost decrease using biogas from solid urban organic waste from centers and grocery market places at Caribbean Region of Colombia.
Highlights
The annual potential of energy production from biomass resource in Colombia is projected to be around 16.260MWh [1], the biomass in Colombia is a plentiful and oldest source of energy in the world
The fuel used for the proper operation of biogas generators, which is produced by anaerobic digestion of collected biomass, which can be processed from livestock manure, either from the poultry, beef or pork sector
It can be seen that the CC&MP sector presents the lower operational cost for a simulation of 25 years, this could be by two reasons, the CC&MP sector presents the lower price by unit (4.45€/ton) and presents an availability required to the right function of the system, the amount of biogas is sufficient and the grid do not work a longer time, it is necessary to highlight that the grid present a price of 0.15€/kWh
Summary
The annual potential of energy production from biomass resource in Colombia is projected to be around 16.260MWh [1], the biomass in Colombia is a plentiful and oldest source of energy in the world. Colombia in particular is a country generator of biomass [2], where the biomass considered is composed of the organic matter of including wood, agricultural residues, human and animal wastes It is a mixture of the some gases like methane (CH4) and carbon dioxide (CO2), produced by micro-organisms in the deficiency of oxygen [3] Renewable energy technologies play an important role on the economic growth of any country [4], and their use had increased due to fuel cost and the energy crisis around the world, becoming an interesting alternative in the energy transitions in this decade [5]. Different study to the base of techno-economic analysis for example [10] achieved ideal development and viability investigation for the rural communal by bearing in mind photovoltaic, hydro, biomass and diesel as energy resources to generate power for the highest capacity of 55.49kW. They executed simulations with HOMER® involving a 6kW biogas generator, 60kW PV, 16kW biomass, and 10kW
