要旨

Moisture-based adsorption thermal batteries (ATBs) have the potential to alleviate the temporal and geographic mismatch between heat producers and heat consumers, but realizing practical applications is still challenging, in spite of the huge developments in novel materials and system design. Here, a proof-of-concept solar Trombe-wall (T-wall)-based ATB prototype with honeycomb-design, scalable, and low-cost CaCl2-based fiber brick with ink (ICFB) sorbents is reported for the first time. The ICFB achieves an outstanding thermal storage capacity of 172.8 kW h m−3 and good stability in heat charging–discharging cycles. Importantly, the idea of the solar chimney effect in passive building heating is introduced into the system structural design to pursue optimal thermal output and energy saving. Together with the rational operating strategy, the T-wall-based ATB prototype shows exceptional thermal performance, achieving a heat discharging power density of 1.97 kW m−3, a discharging efficiency of 64.8%, an energy utilization coefficient of 0.87 kW ht kW hc−1, and an energy consumption coefficient of 1.32 kW he kW hts−1 reduced by 54.2% in comparison with 100%-electricity use, demonstrating its adaptability and possibility of realizing day and night heating in low-carbon scenarios.

Energy & Environmental Science is an international journal dedicated to publishing exceptionally important and high quality, agenda-setting research tackling the key global and societal challenges of ensuring the provision of energy and protecting our environment for the future. The scope is intentionally broad and the journal recognises the complexity of issues and challenges relating to energy conversion and storage, alternative fuel technologies and environmental science. For work to be published it must be linked to the energy-environment nexus and be of significant general interest to our community-spanning readership. All scales of studies and analysis, from impactful fundamental advances, to interdisciplinary research across the (bio)chemical, (bio/geo)physical sciences and chemical engineering disciplines are welcomed. Topics include, but are not limited to, the following: Solar energy conversion and photovoltaics Solar fuels and artificial photosynthesis Fuel cells Hydrogen storage and (bio) hydrogen production Materials for energy systems Capture, storage and fate of CO2, including chemicals and fuels from CO2 Catalysis for a variety of feedstocks (for example, oil, gas, coal, biomass and synthesis gas) Biofuels and biorefineries Materials in extreme environments Environmental impacts of energy technologies Global atmospheric chemistry and climate change as related to energy systems Water-energy nexus Energy systems and networks Globally applicable principles of energy policy and techno-economics
