“…Energy storage is expected to be capable of redistributing solar power collected during the day to the nighttime hours (Albertus et al, 2020), however, storage costs would need to come down roughly two orders of magnitude in order to allow for near 100% renewable electricity systems to cope with longer term variability in the wind and solar resource, while keeping system costs near their current levels (Sepulveda et al, 2018;Tong et al, 2020).…”

“…In this work we study the weekly timescale as it is relevant for the type of energy system that may exist within the next several decades where there is sufficient energy storage and transmission to adequately buffer the daily solar cycle but not necessarily longer-term variation in wind and solar energy supply (Albertus et al, 2020). The weekly timescale also encapsulates the societal cycle in electricity demand associated with the calendar week.…”

Wind and solar electricity generation is projected to expand substantially over the next several decades due both to rapid cost declines as well as regulation designed to achieve climate targets. With increasing reliance on wind and solar generation, future energy systems may be vulnerable to previously underappreciated synoptic-scale variations characterized by low wind and/or surface solar radiation. Here we use western North America as a case study region to investigate the historical meteorology of weekly-scale “droughts” in potential wind power, potential solar power and their compound occurrence. We also investigate the covariability between wind and solar droughts with potential stresses on energy demand due to temperature deviations away human comfort levels. We find that wind power drought weeks tend to occur in late summer and are characterized by a mid-level atmospheric ridge centered over British Columbia and high sea level pressure on the lee side of the Rockies. Solar power drought weeks tend to occur near winter solstice when the seasonal minimum in incoming solar radiation co-occurs with the tendency for mid-level troughs and low pressure systems over the U.S. southwest. Compound wind and solar power drought weeks consist of the aforementioned synoptic pattern associated with wind droughts occurring near winter solstice when the solar resource is at its seasonal minimum. We find that wind drought weeks are associated with high solar power (and vice versa) both seasonally and in terms of synoptic meteorology, which supports the notion that wind and solar power generation can play complementary roles in a diversified energy portfolio at synoptic spatiotemporal scales over Western North America.

“…Further, any RFB system should meet the overall DOE / ARPA-E cost targets that have been documented to have any chance at a viable pathway to commercialization. 5,48,49 In this paper, we: a) identify the characteristics of such an ideal RFB system, b) identify Ti and Ce as abundantly available electroactive species satisfying these criteria, c) elucidate their electrochemistry, d) develop a Ti-Ce electrode-decoupled RFB (ED-RFB) employing our unique and highly perm-selective anion exchange membrane (AEM) separator that permits the use of dis-similar actives at either electrode without irreversible capacity-fade, e) test the ED-RFB over a long time frame (1300 hours) employing long-duration (24-hr) cycles that mimic real world usage, and f) show through detailed techno-economic analyses that our ED-RFB system can comfortably attain a levelized cost of storage (LCOS) of <$0.05/kWh-cycle when deployed at scale, thereby being cheaper then established DOE targets for grid-storage applications.…”

Redox-flow batteries (RFBs) enable large-scale energy storage at low cost due to the independent scaling of device power and energy, thereby unlocking energy arbitrage opportunities and providing a pathway to grid stability and resiliency. Herein we demonstrate an “electrode-decoupled” redox-flow battery (ED-RFB) with titanium and cerium elemental actives that has a clear pathway to achieve a levelized cost of storage (LCOS) of ca $0.025/kWh-cycle. A key enabling technology is our highly perm-selective modified poly(ether ketone)-based anion exchange membrane (AEM) that ensures long term separation of Ti and Ce species and enables capacity-fade-free cycling over 1300 hours of operation. Further, our Ti-Ce ED-RFB exhibits negligible capacity fade when the actives are charged to 90% state of charge (SOC), stored for close to 100-hours and then discharged, rendering it viable for long duration (load-following) grid-scale energy storage applications. Herein we introduce the Ti-Ce ED-RFB as a novel, low-cost long duration energy storage (LDES) system.

“…Larger-scale applications require specifically designed batteries. For example, lithium ion batteries are economically viable only for short-duration energy storage (<10 h discharge), where the value of the energy that they generate is higher than their own cost [ 12 ]; thus, they are unsuitable for the long-duration storage needed for renewables.…”

The increasing share of renewables in electric grids nowadays causes a growing daily and seasonal mismatch between electricity generation and demand. In this regard, novel energy storage systems need to be developed, to allow large-scale storage of the excess electricity during low-demand time, and its distribution during peak demand time. Acid–base flow battery (ABFB) is a novel and environmentally friendly technology based on the reversible water dissociation by bipolar membranes, and it stores electricity in the form of chemical energy in acid and base solutions. The technology has already been demonstrated at the laboratory scale, and the experimental testing of the first 1 kW pilot plant is currently ongoing. This work aims to describe the current development and the perspectives of the ABFB technology. In particular, we discuss the main technical challenges related to the development of battery components (membranes, electrolyte solutions, and stack design), as well as simulated scenarios, to demonstrate the technology at the kW–MW scale. Finally, we present an economic analysis for a first 100 kW commercial unit and suggest future directions for further technology scale-up and commercial deployment.
