The carbon dioxide removal potential of Liquid Air Energy Storage: A high-level technical and economic

Andrew LOCKLEY, Ted von HIPPEL

Frontiers of Engineering Management 2021, Volume 8, Issue 3,   Pages 456-464 doi: 10.1007/s42524-020-0102-8

Abstract: Liquid Air Energy Storage (LAES) is at pilot scale.Air cooling and liquefaction stores energy; reheating revaporises the air at pressure, powering a turbinegeological storage of this CO – offering a novel Carbon Dioxide Removal (CDR) by-product, for the energySimilarly, established Compressed Air Energy Storage (CAES) uses air compression and subsequent expansionwithin a century (ignoring siting constraints) – but this must be costed against competing CDR and energy

Energy rebound effect in China’s manufacturing sector: Fresh evidence from firm-level data

Frontiers of Engineering Management   Pages 439-451 doi: 10.1007/s42524-022-0210-8

Abstract: The rebound effect refers to the phenomenon that individuals tend to consume more energy in the faceof energy efficiency improvement, which reduces the expected energy-saving effect.To fill this gap, we use China’s firm-level data to estimate the rebound effect in China’s manufacturingwhole, the declined trend of the rebound effect is driven by the descent of minority sectors with high energyconsumption and high energy-saving potential.
