Kouwerberg, Sang Jae (author), Alpizar Castillo, J.J. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)Batteries are one of the main tools to provide the flexibility distribution and transmission systems need due to their increasing dependence on weather conditions. However, environmental and economic factors pose a significant problem. New types of batteries that do not rely on rare earth metals and organic solvents but instead use water and...conference paper 2023

Ramesh Kumar, K. (author), Tasinafo Honório, H. (author), Hajibeygi, H. (author)Successful transition to renewable energy supply depends on the development of cost-effective large-scale energy storage technologies. Renewable energy can be converted to (or produced directly in the form of) green gases, such as hydrogen. Subsurface formations offer feasible solutions to store large-scale compressed hydrogen. These...conference paper 2023

(author), Marence, M. (author), Bricker, J.D. (author)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...review 2022

Mangel Raventos, A. (author), Kortlever, R. (author)The effect of different alkali metal cations on the oxygen evolution activity and battery capacity of nickel electrodes has recently been studied in low concentration alkali hydroxide electrolytes. As high concentration hydroxide electrolytes are favored in applications due to their high conductivity, we investigate if the cation effects...journal article 2022

Marchand, J. (author), Shetgaonkar, A.D. (author), Rueda, José L. (author), Lekić, A. (author), Palensky, P. (author)Due to their weak nature, such as low inertia, offshore energy hubs are prone to unprecedented fast dynamic phenomena. This can lead to undesired instability problems. Recent literature, with main focus on onshore systems, suggests that electrolysers could be an attractive option to support wind generators in the mitigation of balancing problems...journal article 2021

Okur, Ö. (author), Heijnen, P.W. (author), Lukszo, Z. (author)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...review 2021
