Optimizing the energy and charging infrastructure costs for regional electric aircraft operations: A case study in the Dutch Caribbean

Commercial electric aircraft operations are foreseen in the coming five to ten years. For an airport to be ready for this introduction, energy infrastructure requirements have already been subject to various research topics. Most research in this field only focused on cost minimization of the number of chargers given a fixed flight schedule....

Planning the deployment of energy storage systems to integrate high shares of renewables: The Spain case study

The intermittent nature of the renewable energy sources with the greater potential, wind and solar, requires dealing with temporary mismatches between demand and supply. The object of this study is to assess the Spanish energy plan from a system perspective regarding the energy storage requirements to meet electricity demand with high...

Low-head pumped hydro storage: A review of applicable technologies for design, grid integration, control and modelling

To counteract a potential reduction in grid stability caused by a rapidly growing share of intermittent renewable energy sources within our electrical grids, large scale deployment of energy storage will become indispensable. Pumped hydro storage is widely regarded as the most cost-effective option for this. However, its application is...

Optimisation-based system designs for deep offshore wind farms including power to gas technologies

A large deployment of energy storage solutions will be required by the stochastic and non-controllable nature of most renewable energy sources when planning for higher penetration of renewable electricity into the energy mix. Various solutions have been suggested for dealing with medium- and long-term energy storage. Hydrogen and ammonia are...

Analysis of strategic renewable energy, grid and storage capacity investments via Stackelberg-cournot modelling

With increasing decarbonisation and accessibility to our energy systems and markets, there is a need to understand and optimise the value proposition for different stakeholders. Game-theoretic models represent a promising approach to study strategic interactions between self-interested private energy system investors. In this work, we design...

Aggregator's business models in residential and service sectors: A review of operational and financial aspects

Flexibility coming from consumers in residential and service sectors has received significant attention to deal with uncertainty and variability of renewable energy sources. Since these consumers are too small individually to participate in the electricity markets, their assets can be pooled by an aggregator. The aggregator can implement...

Added value of Energy Storage Systems: A valuation model of ESS for industrial clusters

Energy storage systems (ESS) are expected to be one of the main pillars for a future renewable based power system. Since all sectors are electrifying and variable renewable energy (VRE) is being deployed more quickly than transmission and distribution operators are able to connect them to the electricity grid. Flexible capacity on multiple...

Power to methane to power: Performance analysis of a closed loop energy storage system

Reducing carbon emissions in the power generation sector can be done by generating energy from renewable sources such as wind and sun. However these sources alone cannot provide a reliable electricity system and therefore an energy storage system is needed. Power-to-gas is a concept in which surplus renewable electricity is used for the...

Unravelling the practical solar charging performance limits of redox flow batteries based on a single photon device system

In recent years, solar redox flow batteries have attracted attention as a possible integrated technology for simultaneous conversion and storage of solar energy. Unlike solar water splitting technologies which require at least 1.8V for meaningful performance, a lesson learned from previous solar redox flow battery (SRFB) studies is that even...

Design and modeling of an energy storage system based on solid oxide reversible cells with syngas as fuel and co-electrolysis of CO2 and H2O
