COMPARISON OF A SINGLE STAGE AND A MULTI STAGE LATENT HEAT STORAGE FOR DOMESTIC HOT WATER DELIVERY KU Leuven
In this paper we assess the potential to use multiple PCM in combination with a compact heat exchanger for direct domestic hot water (DHW) delivery purposes for e.g. district heating substations. The results of the measurements on a compact thermal energy storage device based on multiple phase change materials (PCM) with different melting temperatures are compared to a geometrical identical system with a single PCM with one melting temperature. ...
Variation in potential feeding value of triticale forage among plant fraction, maturity stage, growing season and genotype Universiteit Gent Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
Cereal forages, such as triticale forage, progressively gain interest as alternative crop for maize. The main study objective was to investigate the variation in potential feeding value of triticale forage among maturity stage, growing season and genotype, using total plant and stem fractions. Therefore, near infrared spectroscopy (NIRS) was evaluated as fast screening tool. The prediction ability was good (ratio of prediction to deviation, RPD ...
Statistical analysis of alternative storage and retrieval strategies in end-of-Aisle automated storage and retrieval systems Universiteit Gent
Alternative storage and retrieval strategies in End-of-Aisle automated storage and retrieval systems are discussed, and their performances are compared. In particular, we analyze and compare results of different storage policies, sequencing rules and layouts that have to be determined in End-of-Aisle systems. The performance analysis is carried out through simulation analysis. The performance measures considered for the evaluation of each ...
Expressive data storage policies for multi-cloud storage configurations KU Leuven
Software-as-a-Service (SaaS) providers increasingly rely on multi-cloud setups to leverage the combined benefits of different enabling technologies and third-party providers. Especially, in the context of NoSQL storage systems, which are characterized by heterogeneity and quick technological evolution, adopting the multi-cloud paradigm is a promising way to deal with different data storage requirements. Existing data access middleware platforms ...
Storage via Power-to-Gas in Future Energy Systems: The Need for Synthetic Fuel Storage in Systems with High Shares of Intermittent Renewables KU Leuven
Rising global temperature concerns drive unprecedented changes in the electrical power system like the massive deployment of intermittent renewable energy sources. Such large-scale renewables deployment requires a variety of flexibility options for the electrical power system to be operated reliably. A possibly important flexibility option is storage. Next to battery storage and pumped hydro storage, which have a comparably small storage ...
Auction-based allocation of shared electricity storage resources through physical storage rights KU Leuven
© 2016 Elsevier Ltd. This article proposes a new electricity storage business model based on multiple simultaneously considered revenue streams, which can be attributed to different market activities and players. These players thus share electricity storage resources and compete to obtain the right to use them in a dynamic allocation mechanism. It is based on the design of a new periodically organized auction to allocate shared storage resources ...
Dynamics of metabolic adaptation during initiation of controlled atmosphere storage of 'Jonagold' apple: Effects of storage gas concentrations and conditioning KU Leuven
© 2016 Elsevier B.V. Controlled atmosphere (CA) storage reduces respiration, ethylene production and related biochemical and physiological changes. The dynamics of the metabolic changes accompanying initial periods of CA storage of 'Jonagold' apples have been studied. The apples were exposed to 1 kPa O2, 3 kPa CO2; 3 kPa O2, 3 kPa CO2; 1 kPa O2, 10 kPa CO2 and air (20.8 kPa O2, 0.03 kPa CO2) was used as a control. The effect of air storage ...
Robust design optimization and stochastic performance analysis of a grid-connected photovoltaic system with battery storage and hydrogen storage Vrije Universiteit Brussel
Balancing of intermittent energy such as solar energy can be achieved by batteries and hydrogen-based storage. However, combining these systems received limited attention in a grid-connected framework and its design optimization is often performed assuming fixed parameters. Hence, such optimization induces designs highly sensitive to real-world uncertainties, resulting in a drastic mismatch between simulated and actual performances. To fill ...
