“…Pumped hydroelectric power plants (PHEs) are one of the most widely used renewable energy production systems in the world [1][2][3][4][5][6][7][8][9][10]. The need for decarbonization, the penetration of renewable energies, and the broader vision of the management of our resources could be obtained with these technologies by improving their storage capacity [11][12][13][14][15].…”

“…Renovating the partially obsolete energy production plant in Gran Canaria is the great challenge, which is already in the process of being renovated and/or dismantled. This plant is more than 30 years old, and its technological standards in terms of the current demanded requirement of minimum fuel consumption, maximum energy production, and minimum emissions are far from the desired expectations for such production [3,[24][25][26][27][28][29][30]. All of this is aggravated by the types of fuel used, fuel oil, and diesel oil, ignoring other alternatives that are environmentally better and even energetically more efficient [24][25][26].…”

Gran Canaria, due to its status as an island, has an isolated energy system (IES). This has made it dependent on itself for energy production, which is basically obtained from: (a) Wind and solar energy, which equals 19% of the total energy produced, (b) Energy obtained from the burning of fossil fuels in the energy production equipment of the existing thermal power stations, which equals 81% of the total energy produced. A solution must be found to the current production system, which is already partially obsolete and is due for renewal and/or decommissioning, in order to avoid “Energy Zero”, which means a change in the production cycle. In addition, the incorporation of a pumped hydroelectric energy storage plant “Chira-Soria” into the Gran Canaria electricity system represents another, even more important, change in the dynamics followed up to now. Basically, this plant, which is hydraulically stabilized by means of a seawater desalination plant, incorporates energy storage by storing water at high altitude to be turbined under appropriate conditions. The new situation will be analyzed with this incorporation and the option of an integrated operation in the overall energy system of Gran Canaria will be considered.

“…However, the wide variability of chemical and physical properties among different types of feedstocks determines a highly variable quality of the resulting syngas [12,13], that practically decrease the degree of suitability of its use in real production systems at a commercial level [14] or, anyhow, determines performances far lower than those achievable by exploiting fossil counterparts (on average, 30% less [15]).…”

Syngas from biomass gasification represents an interesting alternative to traditional fuels in spark-ignition (SI) internal combustion engines (ICEs). The presence of inert species in the syngas (H2O, CO2, N2) reduces the amount of primary energy that can be exploited through combustion, but it can also have an insulating effect on the cylinder walls, increasing the average combustion temperature and reducing heat losses. A predictive numerical approach is here proposed to derive hints related to the possible optimization of the syngas-engine coupling and to balance at the best the opposite effects taking place during the energy conversion process. A three-dimensional (3D) computational fluid dynamics (CFD) model is developed, based on a detailed kinetic mechanism of combustion, to reproduce the combustion cycle of a cogenerative engine fueled by syngas deriving from the gasification of different feedstocks. Numerical results are validated with respect to experimental measurements made under real operation. Main findings reveal how heat transfer mainly occurs through the chamber and piston walls up to 50° after top dead center (ATDC), with the presence of inert gases (mostly N2) which decrease the syngas lower calorific value but have a beneficial insulating effect along the liner walls. However, the overall conversion efficiency of the biomass-to-ICE chain is mostly favored by high-quality syngas from biomasses with low-ashes content.

“…The synthesis gas obtained in this way can possibly be used for the production of hydrogen, which can be used as an input raw material in the chemical production of synthesis fuels. Another possibility is to use synthesis gas as a gaseous fuel [18,19,[24][25][26][29][30][31]. Of course, synthesis fuels can be created from various organic substrates.…”

High-Energy Synthesis Gases from Waste as Energy Source for Internal Combustion Engine

The aim of the presented article is to analyse the influence of the composition of synthesis gases with mass lower heating values in the range from 12 to 20 MJ/kg on the performance, economic, and internal parameters of an atmospheric two-cylinder spark-ignition combustion engine suitable for a micro-generation unit. The analysed performance parameter was the torque. The economic parameters analysed were the hourly fuel consumption and the engine’s effective efficiency. The analysed internal parameters of the engine were the indicated mean effective pressure, the pressure profiles in the cylinder, the course of the maximum pressure in the cylinder, and the course of the burning-out of the fuel in the cylinder. The analysed synthesis gases were produced by thermo-chemical processes from waste containing combustible components (methane, hydrogen and carbon monoxide) as well as inert gases (carbon dioxide and nitrogen). Higher hydrocarbons, which may be present in a synthesis gas, were not considered in this contribution because of their easy liquefaction at higher pressures in pressure bottles. A total of ten gases were analysed, all of which fall into the category of high-energy synthesis gases. The measured data from the operation of the combustion engine running on the examined gases were compared with the reference fuel methane. The measured results show a decrease in the performance parameters and an increase in the hourly fuel consumption for all operating loads. Specifically, at the engine speed of 1500 rpm, the drop in performance parameters was in the range from 9% to 24%. The performance parameters were directly proportional to the lower volumetric heating value of the stoichiometric mixture of gases with air. The rising fuel consumption proportionally matched the increase in the mass proportion of fuel in the stoichiometric mixture with air. The effective efficiency of the engine varied from 27.4% to 31.3% for different gas compositions, compared to 31.6% for methane. The conclusive results indicate that the proportion of hydrogen, methane and inert gases in the stoichiometric mixture of synthesis gases with air has the greatest influence on the course of fuel burning-out. The article points to the potential of energy recovery from waste by transforming waste into high-energy synthesis gases and their use in cogeneration.
