Abstract. This study evaluates the types of biomass that can be used in boilers for the production of steam and hot water for the Lauro Wanderley University Hospital located in the city of João Pessoa, Paraíba, Brazil, using average cost of production and business model analysis (Business Model Canvas). The study was conducted to subsidize a system for the optimization of the energy resources to be adopted by the hospital, as the design of a product or service production system can identify opportunities to reduce costs and environmental damage. The energy demand of the hospital was surveyed. Only firewood, sugarcane bagasse and pellets were considered in the analysis, as these are the types of biomass allowed in the specified boiler. The results showed that the pellets were the costliest resource, whereas firewood exhibited the best results considering the average cost of production and the business model. This information supports more consistently the adequate inclusion of this resource in the hospital superstructure and, consequently, the optimization of the polygeneration system, allowing clearer verification of decreased costs and environmental impacts.Keywords: Biomass, polygeneration system, cost of production, hospital. IntroductionOver the last few years, the use of multiple energy sources in energy supply systems to guarantee reliability and improve energy use has been gaining attention [1][2][3][4][5][6]. Polygeneration, as it is more commonly known, is defined as the combined production of two or more energy services to reach the maximum use of the various energy sources used. Its main advantage is the efficient use of these sources, as it requires detailed study of the generation-consumption ratio, the reliability and continuity of the energy supply and the system's improvements compared to autonomous systems. Polygeneration and energy integration are promising tools for achieving better efficiency in the use of natural resources and, in most cases, also reducing the environmental impacts generated [2]. Examples of the application of polygeneration systems include the commercial [7][8][9], domestic [10][11], and industry [12][13] sectors Some consumption units, such as hospitals, exhibit high energy consumption and require continuous and simultaneous electric and thermal energy [14][15][16]. Therefore, hospitals are excellent units with potential for deploying polygeneration systems, as their comfort conditions and electricity, hot water, heating and air conditioning demands must be continuously met. There are recent studies on the optimization of polygeneration systems in hospitals [17][18][19]. However, the optimal configuration of these systems still represents a complex problem due to the wide variety of technological options for energy supply and conversion and the large daily and annual variations in energy demands and in energy prices and rates. According to Shang and Kokossis [20], variability in energy demand requires a project methodology that results in efficient production systems (ther...

“…[8] A clear synergy between CSP and desalination can be seen, with the seawater acting as a cold reservoir for the CSP's Rankine cycle, and the cycle's condenser acting as a low-cost thermal energy source for the MED process, in a cogeneration-like fashion. Similar configurations have been proposed with combined cycles [9], nuclear reactors [10], and more recently with low-enthalpy renewable energies such as geothermal [11] and solar [12,13], combined with Organic Rankine Cycles [14] and in hybrid polygeneration facilities [15].…”

Thermophysical properties and corrosion characterization of low cost lithium containing nitrate salts produced in northern Chile for thermal energy storage AIP Conference Proceedings 1734, 050014 (2016) Abstract. The mining industry is a great consumer of water for hydrometallurgical processes. Despite the efforts in minimizing the use of fresh water through reuse, recycling and process intensification, water demand for mining is expected to rise a 40% from 2013 to 2020. For seawater to be an alternative to groundwater, it must be pumped up to the mine (thousands of meters uphill) and desalinated. These processes require intensive energy and investment in desalination and piping/pumping facilities. A conventional solution for this process would be desalination by reverse osmosis at sea level, powered by electricity from the grid, and further pumping of the desalinated water uphill. This paper compares the feasibility of two solar technologies versus the "conventional" option. LCOW (Levelized Cost of Water) was used as a comparative indicator among the studied solutions, with values for a lifetime of 10, 15, 20 and 25 years, calculated using a real discount rate equal to 12%. The LCOW is lower in all cases for the RO + grid solution. The cost of desalination, ignoring the contribution of pumping, is similar for the three technologies from twenty years of operation. The use of solar energy to desalinate sea water for consumption in the mines of the Atacama region is technically feasible. However, due to the extra costs from pumping whole seawater, and not just the desalinated water, solar solutions are less competitive than the conventional process.

Abstract-Integrated systems of FT liquids processes and waste energy utilization based on Shell, GSP and GE gasification are designed and simulated. The results show that under the condition of 1 000 t/hr coal feedstock, the yields of the liquids, including diesel, naphtha and LPG, are 205.2t/hr, 73.2t/hr and 40.1t/hr, respectively based on shell; 205.1t/hr, 73.2t/hr and 40.1t/hr, respectively based on GSP; 183.8t/hr, 65.6t/hr and 35.9t/hr respectively based on GE. However, the electricity generation equivalent to about 2% of coal thermal value cannot meet the power needs of the three systems. Based on LHV, the highest system thermal efficiency of 47.7% comes from the system based on Shell. The lowest system thermal efficiency, resulting from the system based on GE, has decreased 7.1% compared with that of the system based Shell. The proportion of carbon capture to the total carbon entering the systems is 58.7% (for the system based on Shell), 58.6% (for the system based on GSP) and 59.5% (for the system based on GE), respectively.
