Short-Term Off-River Pumped Hydro Energy Storage (STORES)
Short-Term Off-River Energy Storage (STORES) is a breed of pumped hydro energy storage which incorporates closed-loop pumped hydro systems located away from rivers. Compared with conventional river-based hydroelectric projects, the STORES facilities consume modest volume of water and have little …

Innovative energy systems and processes based on hydrogen from RES and its derivatives in the energy transition process
This thesis investigates the integration of green hydrogen and ammonia production in renewable energy-powered energy systems, as a decarbonization pathway in the energy sector. Climate change mitigation and the transition to carbon-free energy systems are challenged by the inherent intermittency of …

A pathway to decarbonised energy
The energy sector accounts for three quarters of global emissions and needs to be the primary focus of decarbonisation. This thesis examines an affordable pathway to decarbonised energy, enabled by 100% renewable electricity and the deep electrification of transport, heat and industry. The proposed …

A comparative analysis and optimisation of thermo-mechanical energy storage technologies
Electrical Energy Storage (EES) can decouple energy production from its consumption and is urgently needed by both conventional energy system for load leveling and renewable energy system for intermittency smoothing. Currently, Pumped Hydro Energy Storage (PHES) and Compressed Air Energy Storage …

Economic valuation of energy storage coupled with photovoltaics : current technologies and future projections
… framework for the economic valuation of current energy storage systems coupled with photovoltaic (PV) systems is presented. The solar-with-storage system's operation is optimized for two different rate schedules: (1) Time-of-use (TOU) for residential systems, and (2) Real-time wholesale rates for …
