“…Since the costs of both technologies are expected to remain in the vicinity of the assumed reference values, the system could benefit from different technologies to provide short and long-term storage. For hydrogen storage, underground salt cavern can reduce the cost of storage energy capacity by two orders of magnitude [24]. This would increase the competitiveness of hydrogen storage but the effect would be less pronounced than the one shown in Figure 12(d) where energy and power capacity are assumed to change simultaneously.…”

Several approaches have been proposed to determine the optimal storage capacity and dispatch strategy in a power system with high renewable penetration. The deployment of alternatives such as sector coupling and reinforcing interconnections among neighbouring countries may reduce the storage capacity that results cost-effective. We use the model PyPSA-Eur-Sec-30, an open, hourly-resolved, one-node-per-country network of the sector-coupled European energy system to investigate the complex interactions among generation technologies, mainly wind and solar PV, storage technologies in the power system (pumped hydro storage [PHS], batteries, and hydrogen storage), and the additional storage brought to the system by coupling the transport (electric vehicle [EV] batteries) and heating sector (short-term and long-term thermal energy storage). The system configuration is optimised under decreasing CO 2 emissions targets. For the power system, significant storage capacities only emerge for CO 2 emissions reduction higher than 80% of 1990 level in that sector. For 95% CO 2 emissions reduction, battery and hydrogen storage energy capacities equivalent respectively to 1.4 and 19.4 times the average electricity demand result cost-effective. The former cycles daily counterbalancing solar generation while the dispatch pattern of the latter is determined by fluctuations in wind generation. Coupling heating and transport sectors enables deeper CO 2 emissions reductions before the required storage capacities diverge. The EV batteries provided by coupling the transport sector avoid the need for additional stationary electric batteries and large energy capacity of centralised thermal energy storage (CTES) is built to deal with the large seasonal variation in heating demand.

“…The other reason we focus on a starting year that would capture the increasing probability of RPS adoption is that, according to the literature on photo‐voltaic (PV) inverters, which are necessary for efficient connection and storage of renewable source‐generated electricity, “smart grid” large system PV dynamic technology innovations reached mass‐market potential around the early 2000s (Delucchi & Jacobson, ; Fthenakis, Mason, & Zweibel, ; Steward, Saur, Penev, & Ramsden, ; Zweibel, Mason, & Fthenakis, ). Although these works mostly focus on solar generation, wind power is subject to the same intermittency problems.…”

This research examines the impact of increasing the stringency of renewable portfolio standards (RPS) on the consumption of energy produced from renewable sources. Putting prior findings in the context of policy learning, first we focus on technological innovation, factor endowments, and economic energy dependence of American states to track how RPS have proliferated and strengthened. Next, we look at the net effect of this RPS evolution on state fossil fuel energy divestment. To evaluate the interplay between: a) the political desire to lower fossil fuel use, b) technological feasibility to do so, and c) the economic trade-offs and risks, we focus on the industrial sector dependence on energy security and affordability. Our results indicate that energy security is a priority and even in light of increasing RPS stringency, states with relatively weak but mandatory RPS are leaders in aggregate renewable energy consumption. This fact is due to favoring biofuel and hydro generation rather than solar and wind because of lower deployment costs.

“…For 20 hours of storage, EPRI estimates a CAES cost of 1150 $/kW [30]. The type of rock formation impacts the underground cavity excavation cost, ranging from 0.10 $/kWh for a porous rock formation to 30 $/kWh for excavation of a hard rock formation [54] [53]. More recent analysis report a similar range for compressed air storage: 0.10 EUR/kWh in porous rock, 1.01 EUR/kWh in solution-mined salt caverns, 9.71 EUR/kWh in dry-mined salt caverns, 9.71 EUR/kWh in abandoned mines, and 29.55 EUR/kWh in rock caverns from excavation [55].…”

The role of electricity storage and hydrogen technologies in enabling global low-carbon energy transitions

Previous studies have noted the importance of electricity storage and hydrogen technologies for enabling large-scale variable renewable energy (VRE) deployment in long-term climate change mitigation scenarios. However, global studies, which typically use integrated assessment models, assume a fixed cost trajectory for storage and hydrogen technologies; thereby ignoring the sensitivity of VRE deployment and/or mitigation costs to uncertainties in future storage and hydrogen technology costs. Yet there is vast uncertainty in the future costs of these technologies, as reflected in the range of projected costs in the literature. This study uses the integrated assessment model, MESSAGE, to explore the implications of future storage and hydrogen technology costs for low-carbon energy transitions across the reported range of projected technology costs.Techno-economic representations of electricity storage and hydrogen technologies, including utility-scale batteries, pumped hydro storage (PHS), compressed air energy storage (CAES), and hydrogen electrolysis, are introduced to MESSAGE and scenarios are used to assess the sensitivity of long-term VRE deployment and mitigation costs across the range of projected technology costs. The results demonstrate that large-scale deployment of electricity storage technologies only occurs when techno-economic assumptions are optimistic. Although pessimistic storage and hydrogen costs reduce the deployment of these technologies, large VRE shares are supported in carbon-constrained futures by the deployment of other low-carbon flexible technologies, such as hydrogen combustion turbines and concentrating solar power with thermal storage. However, the cost of the required energy transition is larger. In the absence of carbon policy, pessimistic hydrogen and storage costs significantly decrease VRE deployment while increasing coal-based electricity generation. Thus, R&D investments that lower the costs of storage and hydrogen technologies are important for reducing emissions in the absence of climate policy and for reducing mitigation costs in the presence of climate policy. List of Acronyms: VRE: variable renewable energy PHS: pumped hydro storage CAES: compressed air energy storage IAM: integrated assessment model MESSAGE: model for energy supply strategy alternatives and their general environmental impact RLDC: residual load duration curve H2: hydrogen CT: combustion turbine GHG: greenhouse gas During the period from 1990 to 2010, variable renewable energy (VRE) deployment increased rapidly, with average annual global primary energy growth rates of 44% and 25% for solar and wind, respectively [1] [2]. This largescale deployment has been motivated by a number of drivers, including government subsidies, rapidly declining investment costs, energy security concerns, and growing global consensus around climate change risks [3] [4]. Future scenarios of the global energy system suggest an even larger role for renewable energy over the next century, particularly if climate policy is introduced....
