Continuous Growth

The continuous growth of renewable energy sources has drastically changed the paradigm of electric energy generation and distribution. Flywheel energy storage systems are a clean and efficient method to level supply and demand in energy grids, including those incorporating renewable energy generation. Environmental safety, resilience, high power capacity and quality make flywheel energy storage very promising. This paper contains a review of flywheel energy storage systems, already being in operation, and applications of flywheel energy storage in general.

Biomass has a large share in the energy generation matrix, due to the regional economic benefits. This work has as main objective to evaluate the parameters used in the manufacture of briquettes produced with forest residues and the economic engineering for the manufacturer. The forest residues were: wood chips and chips of Eucalyptus spp. and barks of Pinus taeda. The evaluations were the chemical characterization of forest residues and the costs involved in the briquetting process. The forest residues presented extractive chemical composition and lignin. The production costs of the briquettes were affected mainly by the equipment, being the Pinus taeda barks the one that presented higher production cost. However, the production costs obtained in this study are approximately 20% lower than the production costs using traditional methods for forest firewood. The energy value from biomass allows the reduction of the dependence of energy, which can be used for the generation of steam or electricity, for subsistence. A fact for energy conversion is to evaluate the material moisture. It is suitable to burn residues with moisture between 45 to 55%. The consumed electric energy is important to evaluate the total costs. The energy required depends on the quality of raw material and the system employed. Forest residues is an important source for eco firewood production, contributing to energy generation and decreasing of the solid waste stored at the company. In this way, the new parameters for briquetting biomass forest wastes shown in this work, which is an important stage of the process, make economically viable and environmentally suitable the eco firewood production.

This article analyses the influence of supporting scheme variants on the profitability of a projected investment of residential photovoltaic systems. The focus of the paper lies in evaluating the feasibility for the power system of solar power generation technologies to achieve a balance between energy generation and support costs in a more efficient way. The case study is based on a year-long time series of examples with an hourly resolution of electricity prices from the Nord Pool power market, in addition to the power demand and solar generation of Latvian prosumers. Electric energy generation and the consumption of big data from more than 100 clients were collected. Based on these data, we predict the processes for the next 25 years, and we estimate economic indicators using a detailed description of the net metering billing system and the Monte-Carlo method. A recommendation to change the current net system to a superior one, taking into account the market cost of energy, concludes the paper.
