Energy storage is increasingly necessary as Variable Renewable Energy (VRE) technologies are deployed. Seasonal energy storage can shift energy generation from the summer to the winter, but these technologies must have extremely large energy capacities and low costs. Geological Thermal energy storage (GeoTES) is proposed as a solution for long-term energy storage. Excess thermal energy can be stored in permeable reservoirs such as aquifers and depleted hydrocarbon reservoirs for several months. In this article, we describe a techno-economic model that has been developed to evaluate GeoTES systems. The models are developed by combining the output of specialist models which enables the performance and cost of both the subsurface and surface systems to be captured. Off-design models are developed so that the performance can be evaluated at each hour of the year. GeoTES can be charged with two different energy sources: (1) concentrating solar thermal and (2) renewable electricity using heat pumps (henceforth known as a "Carnot Battery"). The stored thermal energy can be used to generate electricity and - uniquely - also directly produce heat that can be used by industrial processes. Furthermore, Carnot-Battery-GeoTES can also be used to form a cold storage reservoir. Preliminary results that quantify the technical and economic performance of these two GeoTES systems are presented.

As renewable power generation becomes the mainstream new-built energy source, energy storage will become an indispensable need to complement the uncertainty of renewable resources to firm the power supply. When phasing out fossil-fuel power plants to meet the carbon neutral utility target in the midcentury around the world, large capacity of energy storage will be needed to provide reliable grid power. The integration of renewable power and storage to support future carbon-free utility has several significant and positive impacts including expanding the renewable generation into the grid, improving the peak-load response, and balancing the electricity supply and demand. Long-duration energy storage (10-100 hours duration) can potentially complement the reduction of fossil-fuel baseload generation that otherwise would risk grid security when a large portion of grid power comes from variable renewable sources. Current energy storage methods based on pumped storage hydropower or batteries have many limitations. Thermal energy storage (TES) has unique advantages in scale and siting flexibility to provide grid-scale storage capacity. A particle-based TES system has promising cost and performance for the future growing energy storage needs. This paper introduces the system and components required for the particle TES to be technically and economically competitive. A technoeconomic analysis based on preliminary component designs and performance shows that the particle TES integrated with an efficient air-Brayton combined cycle power system can provide power for several days by low-cost, high-performance storage cycles. It addresses grid storage needs by enabling large-scale grid integration of intermittent renewables like wind and solar, thereby increasing their grid value. The design specifications and cost estimations of major components in a commercial scale system are presented in this paper. The cost model provides insights for further development and cost comparison with competing technologies.

Energy Storage not only plays an important role in conservinq the energy but also improves the performance and reliability of a wide range of energy systems. Energy storagp. leads to saving of premium fuels and makes the system morA cost effective by reducing the wastage of energy. In most systems there is a mismatch between the energy supply and energy demand. The energy storage can even out this imbalance and thereby help in savings of capital costs. Enerqy storage is all the more important where the enerqy source is intermittent such as Solar Energy. The use of jntermittent energy sources is likely to grow. If more and more solar energy is to be used for domestic and industrial applications then energy storage is very crucial. If no storage is used in solar energy systems then the major part of the energy demand will be met by the back-up or auxiliary energy and therefore the so called annual solar load fract]on will be very low. In case of solar energy, both short term and long term energy storage systems can be used whjch can adjust the phase difference between solar energy supply and energy demand and can match seasonal demands to the solar availability respectively. Thermal energy storage can lead to capital cost savings, fuel savjngs, and fuel substitution in many application areas. Developing an optimum thermal storaqe system is as important an area of research as developinq an alternative source of energy.

This paper focuses on simulating hybrid solar energy-combined heat and power-battery storage systems with different sizes, types, and number to determine the optimal system configurations with the goal of minimizing life-cycle cost and maximizing fossil energy savings. A micro-grid solar photovoltaic generation subsystem operated in parallel with, a gas-fired engine and a battery storage subsystem and operating within a macro-grid connected environment is modeled. The hybrid system supplies the micro-grid system dynamic electrical and thermal demands, which is simulated by HOMER (Hybrid Optimization of Multiple Electric Renewables). In this study, solar energy is to meet the peak micro-grid system electrical demand. Considering the fluctuations of solar energy production, the gas-fired engine is used to supply unmet, micro-grid electrical demands. The engine is sized with part load operating characteristics to allow excess PV-engine-battery generation for sales back to macro-grid on high solar flux, high macro-grid demand days. Because the hybrid system choices could change with key factors variations, this study takes into account some factors, like demand profile from two building types, initial component installment cost, and the energy price to make technical and economic analysis. For instance, commercial and industrial buildings with different electrical and thermal demand profile should be considered separately and decreasing PV system price and fuel price could be an opportunity for hybrid system. Also, the study evaluates the potential impact of dispatch strategies on energy savings and explore the correlations between each operating component size and energy cost.

"Renewable energies, such as wind and solar, are a growing piece of global energy consumption. The chief motivation to develop renewable energy is two-fold: reducing carbon dioxide emissions and reducing dependence on diminishing fossil fuel supplies. Energy storage is critical to the growth of renewable energy because it allows for renewably-generated electricity to be consumed at times when renewable sources are unavailable, and it also enhances power quality (maintaining voltage and frequency) on an electric grid which becomes increasingly unstable as more renewable energy is added. There are numerous means of storing energy with different advantages, but none has emerged as the clear solution of choice for renewable energy storage. This thesis attempts to explore the current and developing state of energy storage and how it can be efficiently implemented with crystalline silicon solar photovotlaics, which has a minimum expected lifetime of 25 years assumed in this thesis. A method of uniformly comparing vastly different energy storage technologies using empirical data was proposed. Energy storage technologies were compared based on both economic valuation over the system life and cradle-to-gate pollution rates for systems with electrochemical batteries. For stationary, non-space-constrained settings, lead-acid batteries proved to be the most economical. Carbon-enhanced lead-acid batteries were competitive, showing promise as an energy storage technology. Lithium-ion batteries showed the lowest pollution rate of electrochemical batteries examined, but both lithium-ion and lead-acid batteries produce comparable carbon dioxide to coal-derived electricity."--Abstract, page iii.
