“…Other pathway such as further treatment to produce bio-methane as suggested in [43], could involve only high m values and high productive substrates to maintain an energy convenience. Then, other research shows foreseeable scenarios where renewable hydrogen storage systems interact with renewable electricity excess and biomass gasification plants to build future sustainable networks [44].…”

Abstract:Urban waste management is one of the most challenging issues in energy planning of medium and large cities. In addition to the traditional landfill method, many studies are investigating energy harvesting from waste, not as a panacea but as a foreseeable solution. Thermo-chemical conversion to biogas, or even bio-methane under certain conditions, could be an option to address this challenge. This study focuses on municipal solid waste conversion to biogas as a local energy supply for the cities. Three urban models and their subdivision into urban areas were identified along with a typical Organic Fraction of Municipal Solid Waste (OFMSW) matrix for each urban area. Then, an energy analysis was carried out to provide an optimization map for an informed choice by urban policy-makers and stakeholders. The results highlighted how the urban context and its use could affect the opportunity to produce energy from waste or to convert it in fuel. So, in this case, sustainability means waste turning from a problem to a renewable resource.

“…For this group, the best results were obtained in Tests 9 (13.36%) and 10 (12.52%), carried out at respectively 350 • C and 353 • C, with conversion efficiencies of 31.63% and 30.04% respectively. The last four tests (11)(12)(13)(14) were carried out with a CO 2 /H 2 ratio equal to one. The methane volume fraction reaches a value of 36.6%, with a temperature of 329 • C. Significant conversion efficiency is obtained at 325-329 • C (59.44% and 63.39% respectively).…”

“…Research on hydrogen technologies has been facing many challenges, including production, storage, and transportation infrastructure [10,11]. It is noteworthy that hydrogen is already proven in current gas grid pipelines and even, in certain fractions, used in well-established end-user devices such as boilers and cookers [12].…”

Abstract:The utilization of the captured CO 2 as a carbon source for the production of energy storage media offers a technological solution for overcoming crucial issues in current energy systems. Solar energy production generally does not match with energy demand because of its intermittent and non-programmable nature, entailing the adoption of storage technologies. Hydrogen constitutes a chemical storage for renewable electricity if it is produced by water electrolysis and is also the key reactant for CO 2 methanation (Sabatier reaction). The utilization of CO 2 as a feedstock for producing methane contributes to alleviate global climate changes and sequestration related problems. The produced methane is a carbon neutral gas that fits into existing infrastructure and allows issues related to the aforementioned intermittency and non-programmability of solar energy to be overcome. In this paper, an experimental apparatus, composed of an electrolyzer and a tubular fixed bed reactor, is built and used to produce methane via Sabatier reaction. The objective of the experimental campaign is the evaluation of the process performance and a comparison with other CO 2 valorization paths such as methanol production. The investigated pressure range was 2-20 bar, obtaining a methane volume fraction in outlet gaseous mixture of 64.75% at 8 bar and 97.24% at 20 bar, with conversion efficiencies of, respectively, 84.64% and 99.06%. The methanol and methane processes were compared on the basis of an energy parameter defined as the spent energy/stored energy. It is higher for the methanol process (0.45), with respect to the methane production process (0.41-0.43), which has a higher energy storage capability.

“…In addition, hydrogen economy covers some other key points regarding hydrogen energy including education, training, safety, standards, and regulations. Currently, there are a lot of research activities taking place in investigating the market need, impact, opportunities, and challenges regarding the transition to and implementation of the hydrogen economy, either nationally, eg, in Australia, Brazil, Canada, China, Ecuador, Germany, Japan, Korea, Lithuania, Mexico, New Zealand, Nigeria, Pakistan, Poland, Portugal, Romania, Slovenia, Spain, Taiwan, Turkey, United Kingdom, United States, or regionally, eg, in Asia, EU, and even the whole world …”

A novel multicriteria sustainability investigation of energy storage systems

Summary Affordable, clean, efficient, flexible, and reliable energy storage is an important component of sustainable energy systems. There are several studies in the literature concentrating on improving the sustainability performance of energy storage systems from economic and technical perspectives. However, a comprehensive performance investigation of energy storage systems that take economic, environmental, social, and technical criteria into account is still needed. For that reason, in the present study, it is aimed to perform a complete assessment and analysis of the sustainability of energy storage systems for residential applications in communities and cities. Pumped hydro, conventional batteries, high‐temperature batteries, flow batteries, and hydrogen are the selected energy storage systems. In order to handle the vagueness and ambiguity during the assessment and to eliminate the perceived hesitancy in the decision makers' preferences, an innovative method, a hybrid hesitant fuzzy multicriteria decision‐making (MCDM) methodology composed of hesitant fuzzy analytic hierarchy process (HFAHP) and hesitant fuzzy technique for order preference by similarity to ideal solution (HFTOPSIS), is utilized to assess the sustainability of the selected systems. In this study, four different performance criteria: economic (power cost and energy cost), environmental (pollutant emissions, area requirement, wastewater quality, and solid waste production), social (safety, accessibility, ease of use, and public acceptance), and technical (efficiency, storage capacity, cycling limit, and performance degradation) are taken into consideration. The performance evaluation results indicate that technical performance has the highest influence and social performance has the lowest influence when evaluating the sustainability of the selected energy storage systems. And hydrogen has the highest sustainability performance compared with the other selected energy storage options.
