Why is seasonal energy storage important?
Energy storage at all timescales, including the seasonal scale, plays a pivotal role in enabling increased penetration levels of wind and solar photovoltaic energy sources in power systems.
What is seasonal thermal energy storage (STES)?
The applications of seasonal thermal energy storage (STES) facilitate the replacement of fossil fuel-based heat supply by alternative heat sources, such as solar thermal energy, geothermal energy, and waste heat generated from industries.
Does seasonal thermal energy storage provide economic competitiveness against existing heating options?
Revelation of economic competitiveness of STES against existing heating options. Seasonal thermal energy storage (STES) holds great promise for storing summer heat for winter use. It allows renewable resources to meet the seasonal heat demand without resorting to fossil-based back up. This paper presents a techno-economic literature review of STES.
Can grid-integrated energy storage reshape seasonal fluctuations?
Grid-integrated seasonal energy storage can reshape seasonal fluctuations of variable and uncertain power generation by reducing energy curtailment, replacing peak generation capacity, and providing transmission benefits.
Are grid-integrated seasonal storage cost-effective?
Most current literature focuses on technology cost assessments and does not characterize the potential grid benefits of seasonal storage to capture the most cost-effective solutions. We propose a model-based approach for comprehensive techno-economic assessments of grid-integrated seasonal storage.
Is there a thermal energy storage system using a depleted oil well?
Other challenges include substantial land and excavation requirements. To address this problem, a novel underground thermal energy storage system using a depleted oil well was proposed in Ref. . The first large-scale PTES project was developed at Stuttgart University in 1984 . Fig. A.2 shows a schematic of system.
