Linking renewables and fossil fuels with carbon capture via energy storage for a sustainable energy future

Abstract

Renewable energy sources and low-carbon power generation systems with carbon capture and storage (CCS) are expected to be key contributors towards the decarbonisation of the energy sector and to ensure sustainable energy supply in the future. However, the variable nature of wind and solar power generation systems may affect the operation of the electricity system grid. Deployment of energy storage is expected to increase grid stability and renewable energy utilisation. The power sector of the future, therefore, needs to seek a synergy between renewable energy sources and low-carbon fossil fuel power generation. This can be achieved via wide deployment of CCS linked with energy storage. Interestingly, recent progress in both the CCS and energy storage fields reveals that technologies such as calcium looping are technically viable and promising options in both cases. Novel integrated systems can be achieved by integrating these applications into CCS with inherent energy storage capacity, as well as linking other CCS technologies with renewable energy sources via energy storage technologies, which will maximise the profit from electricity production, mitigate efficiency and economic penalties related to CCS, and improve renewable energy utilisation.

Precise regulation of defect concentration in MOF and its influence on photocatalytic overall water splitting

“…The rise in global energy consumption, drastic depletion of fossil fuel resources, and the associated negative environmental issues have triggered the urgent demand for the development of a variety of sustainable and clean energy conversion technologies. [1][2][3][4] The production of hydrogen via solar-driven water splitting has been considered as an attractive approach for solar energy conversion. [5][6][7] The overall water splitting (H 2 O = H 2 + 1/2O 2 ) consists of two half-reactions: hydrogen evolution reaction (HER) and oxygen evolution reaction (OER).…”

“…[8][9][10] The three major steps of the photocatalytic water splitting process can be summarized as light absorption, charge separation and surface reactions for H 2 or O 2 evolution. 11 Therefore, the following aspects must be considered when designing the photocatalysts for photocatalytic water splitting: (1) the bandgap of photocatalysts. The proper bandgap energy in photocatalysts is particularly important for improving the util-ization of solar energy.…”

Interface‐Anchored Covalent Organic Frameworks@Amino‐Modified Ti3C2Tx MXene on Nylon 6 Film for High‐Performance Deformable Supercapacitors

“…% capacitance remains for COF@N-Ti 3 C 2 T x /DPA after 10000 cycles. [42] For the exploration of practical working environment capability, we constructed a film-based solid-state D-SCs. Generally, the asymmetric D-SCs are assembled by the COF@N-Ti 3 C 2 T x /DPA as anode and CNT film as cathode sandwiched with the PET packages and divided by H 2 SO 4 / PVA gel electrolyte.…”

Carbon Capture and Storage: Application in the Oil and Gas Industry

“…CCS can assist in decreasing the industry's reliance on fossil fuels and boost the accessibility of low-carbon energy sources, like renewable energy, by capturing and storing CO 2 emissions [122,123]. The shift to a low-carbon economy can also be assisted by CCS [124].…”
