“…In recent years, as the global “carbon peak” and “carbon neutral” goals have been proposed, the demand and utilization of wind energy and photovoltaic (PV) renewable energy have received particular attention . It is worth pointing out that the large-scale integration of random and intermittent renewable energy sources will greatly undermine the stability of the grid system. − Therefore, it is necessary to configure a suitable energy storage system on the power generation side and the user side to stabilize the intermittentness and fill the gap between power generation and load. − …”

Vanadium redox flow batteries (VRFBs) can effectively solve the intermittent renewable energy issues and gradually become the most attractive candidate for large-scale stationary energy storage. However, their low energy density and high cost still bring challenges to the widespread use of VRFBs. For this reason, performance improvement and cost reduction of VRFBs are the keys to their commercialization and large-scale energy storage applications. On the basis of this, this perspective briefly describes the development status of renewable energy and energy storage technology and summarizes the existing bottlenecks that affect the development of VRFBs. Meanwhile, the critical technologies of VRFBs are reviewed, and the research progress in recent years and the challenges that need to be overcome are introduced. This perspective focuses on four aspects, including core component material, system modeling, optimization operations, and future business challenges. Then, a comprehensive analysis of critical issues and solutions for VRFB development are discussed, which can effectively guide battery performance optimization and innovation. The views in this perspective are expected to provide effective and extensive understanding of the current research and future development of vanadium redox flow batteries.

Realizing ambitions: A framework for iteratively assessing and communicating national decarbonization progress

et al. 2022

Summary A growing number of governments are pledging to achieve net-zero greenhouse gas emissions by mid-century. Despite such ambitions, realized emissions reductions continue to fall alarmingly short of modeled energy transition pathways for achieving net-zero. This gap is largely a result of the difficulty of realistically modeling all the techno-economic and sociopolitical capabilities that are required to deliver actual emissions reductions. This limitation of models suggests the need for an energy-systems analytical framework that goes well beyond energy-system modeling in order to close the gap between ambition and reality. Toward that end, we propose the Emissions-Sustainability-Governance-Operation (ESGO) framework for structured assessment and transparent communication of national capabilities and realization. We illustrate the critical role of energy modeling in ESGO using recent net-zero modeling studies for the world's two largest emitters, China and the United States. This illustration leads to recommendations for improvements to energy-system modeling to enable more productive ESGO implementation.

“…To overcome global warming, the EU Commission committed to emit at least 55% less greenhouse gas emissions by 2030 and become climate-neutral by 2050. To decarbonize the energy systems, one solution is to increase renewable power penetration, e.g., solar and wind, in energy systems [2]. By increasing the penetration of renewable energies, the intermittency of power systems increases considerably.…”

In recent years, environmental concerns about climate change and global warming have encouraged countries to increase investment in renewable energies. As the penetration of renewable power goes up, the intermittency of the power system increases. To counterbalance the power fluctuations, demand-side flexibility is a workable solution. This paper reviews the flexibility potentials of demand sectors, including residential, industrial, commercial, and agricultural, to facilitate the integration of renewables into power systems. In the residential sector, home energy management systems and heat pumps exhibit great flexibility potential. The former can unlock the flexibility of household devices, e.g., wet appliances and lighting systems. The latter integrates the joint heat–power flexibility of heating systems into power grids. In the industrial sector, heavy industries, e.g., cement manufacturing plants, metal smelting, and oil refinery plants, are surveyed. It is discussed how energy-intensive plants can provide flexibility for energy systems. In the commercial sector, supermarket refrigerators, hotels/restaurants, and commercial parking lots of electric vehicles are pointed out. Large-scale parking lots of electric vehicles can be considered as great electrical storage not only to provide flexibility for the upstream network but also to supply the local commercial sector, e.g., shopping stores. In the agricultural sector, irrigation pumps, on-farm solar sites, and variable-frequency-drive water pumps are shown as flexible demands. The flexibility potentials of livestock farms are also surveyed.
