Future cost and performance of water electrolysis: An expert elicitation study
TL;DR: In this paper, the authors present expert views on future capital cost, lifetime and efficiency for three electrolysis technologies: alkaline (AEC), proton exchange membrane (PEMEC) and solid oxide electrolysis cell (SOEC).
Journal ArticleDOI
The survey of key technologies in hydrogen energy storage
TL;DR: In this article, the authors provide an overall survey of the key technologies in hydrogen energy storage system, ranging from hydrogen production using both fossil fuels, biomass and electricity generated from renewable power sources, to hydrogen storage in both pressurised gas, liquefied and material-based methods, as well as associated electricity generation technologies using hydrogen.

Energy storage in the energy transition context: A technology review
A.B. Gallo,José R. Simões-Moreira,Hirdan Katarina de Medeiros Costa,Marilin Mariano dos Santos,E. Moutinho dos Santos +4 more
TL;DR: In this article, the authors present a comprehensive updated review of energy storage technologies, briefly address their applications and discuss the barriers to energy storage deployment, and point out that no ES technology outstands simultaneously in all technical characteristics and consequently, selection should be driven on a case base analysis.

A review at the role of storage in energy systems with a focus on Power to Gas and long-term storage
Herib Blanco,André Faaij +1 more
TL;DR: In this paper, a review of more than 60 studies (plus m4ore than 65 studies on P2G) on power and energy models based on simulation and optimization was done, based on these, for power systems with up to 95% renewables, the electricity storage size is found to be below 1.5% of the annual demand (in energy terms).

Technical challenges associated with the integration of wind power into power systems
TL;DR: In this article, the main technical challenges associated with the integration of wind power into power systems are discussed, including effects of wind energy on the power system, the power systems operating cost, power quality, power imbalances, power system dynamics, and impacts on transmission planning.
Journal ArticleDOI
Multi-time period combined gas and electricity network optimisation
TL;DR: In this paper, a multi-time period combined gas and electricity network optimisation model was developed, taking into account the varying nature of gas flows, network support facilities such as gas storage and the power ramping characteristics of electricity generation units.
Journal ArticleDOI
A mathematical framework for modelling and evaluating natural gas pipeline networks under hydrogen injection
TL;DR: In this paper, the authors presented a framework of a mathematical formulation for modelling and evaluating natural gas pipeline networks under hydrogen injection, based on gas transport through pipelines and compressors, which compensate for the pressure drops by implying mainly the mass and energy balances on the basic elements of the network.

Effect of H2-injection on the thermodynamic and transportation properties of natural gas
TL;DR: In this article, the influence of hydrogen on the thermodynamics upon injection, on the Joule-Thomson effect at the pressure reduction stations, on energy density, on Wobbe index, and on the pressure drop in the pipelines has been calculated.
