“…The remainder is assumed to be paired with new, utility-scale solar PV. The resulting ratio of storage power capacity to solar PV capacity is approximately 14%, which falls within the estimated range of optimal storage-tosolar PV power capacity from recent work evaluating increased solar PV integration in North Carolina (Virguez, Wang, and Patiño-Echeverri 2021). Figure 17 illustrates the location of new storage capacity for the 2030 nodal model.…”

“…While it may be possible to achieve greater avoided emissions from offset electricityand potentially a negative net GWPthrough intentional system behavior and arbitrage, ,− this behavior is not achievable in any profit-maximizing peaker replacement scenarios explored (in the context of the 2018–2020 grid) and may lead to significantly reduced revenues and increased costs associated with battery sizing due to higher degradation from cycling.…”

“…While replacing peaker power plants does reduce air quality-related health damages in surrounding communities, the profit-maximizing behavior for the BESS we modeled also increased life-cycle GHG emissions once the embodied emissions in the BESS were accounted for. It may be possible to achieve a net zero or negative GWP through an intentional arbitrage strategy to reduce emissions , and the installation of additional renewable resources on the grid can increase the likelihood that BESS will offer net environmental benefits. , In the near-term, optimizing for emissions reductions would be less profitable due to increased cycling and reduced availability for frequency regulation.…”

Falling costs of lithium-ion (Li-ion) batteries have made them attractive for grid-scale energy storage applications. Energy storage will become increasingly important as intermittent renewable generation and more frequent extreme weather events put stress on the electricity grid. Environmental groups across the United States are advocating for the replacement of the highest-emitting power plants, which run only at times of peak demand, with Li-ion battery systems. We analyze the life-cycle cost, climate, and human health impacts of replacing the 19 highest-emitting peaker plants in California with Li-ion battery energy storage systems (BESS). Our results show that designing Li-ion BESS to replace peaker plants puts them at an economic disadvantage, even if facilities are only sized to meet 95% of the original plants’ load events and are free to engage in arbitrage. However, five of 19 potential replacements do achieve a positive net present value after including monetized climate and human health impacts. These BESS cycle far less than typical front-of-the-meter batteries and rely on the frequency regulation market for most of their revenue. All projects offer net air pollution benefits but increase net greenhouse gas emissions due to electricity demand during charging and upstream emissions from battery manufacturing.

“…Also, an effective influence on reducing greenhouse emissions could be possible, which has often been indicated in the case of deploying PVs in natural outdoor climatic conditions. [110][111][112] Interestingly, the lifetime of supercapacitors at RT-based operating conditions, in general, remains far higher than traditional rechargeable batteries [113][114][115][116] and offers opportunities for realizing infinite functioning lifetime-based maintenance-free IoT solutions as demonstrated in this work. From such key viewpoints, the printable CPSC devices fabricated in this work hold immense potential for meeting numerous above-mentioned characteristics and developing self-power-based autonomous solutions for indoor applications.…”

Energy harvesting technologies collect various forms of ambient energies such as heat, light, or vibrations to generate electricity at micro scales. [1,2] Provided that the wasted energy dissipated in the environment is ubiquitous, energy harvesters present the potential to be self-sustaining with an ideal infinite functioning lifetime. Therefore, they have been considered a potential alternative to the traditional battery-based energy solutions presently enforced to energize electronic consumer goods, the Internet of Things (IoT), or other distributed electronic-based ecosystems. [3,4] Since many of these electronic devices are typically located inside buildings, there is great potential for energizing them via integrating photovoltaics (PVs) that can harvest abundantly available ambient indoor light energy from LED, halogen, and FL lamps or other types of light sources. This promising approach can be used to achieve sustainability within portable electronic devices, as well as in advanced-distributed electronic environments. [3,[5][6][7][8][9] Keeping this motivation in mind, established silicon (Si) solar cell-based PV technologies have initially been deployed to harvest ambient light energy for energizing various low-powered electronic appliances such as calculators, digital thermometers, and electronic clocks. [10] However, the low power conversion efficiency under lowlight conditions, combined with high production costs have limited their widespread use in indoor applications. [7,8,11] In contrast to Si-based PVs, third-generation-based solar cell technologies such as organic solar cells (OSC) or dye-sensitized solar cells (DSSC) have shown striking performance with higher conversion efficiencies when tested under indoor light conditions. [12][13][14][15][16][17][18][19] Similar to these third-generation-based PV technologies, the escalating conversion efficiencies of perovskite solar cells (PSCs) under standard illumination conditions [20,21] consequently motivated research labs worldwide to also examine their PV performance under various ambient light intensities. [6,[22][23][24][25][26] As expected, the striking conversion efficiencies of PSCs achieved in recent years (Table 1) under these ambient light intensity conditions provide preliminary evidence for considering them as another potential light-harvesting solution for energizing
