Edward Barbour obtained his bachelor’s degree in Physics from Oxford University and his PhD in Mechanical Engineering from the University of Edinburgh in 2013. His doctoral thesis focused on the development of ACAES and the economics of energy storage within the UK market framework. He held subsequent postdoc positions at the University of Birmingham and Massachusetts Institute of Technology. As of 2019, he is a lecturer at Loughborough University in the Centre for Renewable Energy Systems Technology (CREST), where his research is focused on thermomechanical energy storage and the future role of energy storage in the UK.

Daniel L. Pottie obtained his bachelor’s in Mechanical Engineering from Universidade Federal de Minas Gerais (UFMG), Brazil in 2016. In the same year, he started as a research assistant at UFMG, developing hydraulic compressed air energy storage technology. He started his MSc degree in the subject in 2018, and his thesis detailed the thermodynamic performance of a novel pumped hydraulic compressed air energy storage (PHCAES) system. He was awarded the degree in September 2019. Currently, he is a PhD candidate at Loughborough University where his research is focused on the development of competitive, efficient, and innovative adiabatic compressed air energy storage.

For decades, technical literature has appraised adiabatic compressed air energy storage (ACAES) as a potential long-duration energy storage solution. However, it has not reached the expected performance indicators and widespread implementation. Here, we reflect on the design requirements and specific challenges for each ACAES component. We use evidence from recent numerical, theoretical, and experimental studies to define the technology-readiness level (TRL). Lastly, we discuss promising new directions for future technology development.

Daniel L. Pottie 于 2016 年获得巴西米纳斯吉拉斯联邦大学（UFMG）机械工程学士学位。同年，他开始在 UFMG 担任研究助理，开发液压压缩空气储能技术。他于 2018 年开始攻读该学科的硕士学位，他的论文详细介绍了一种新型泵送液压压缩空气储能 (PHCAES) 系统的热力学性能。他于 2019 年 9 月获得学位。 目前，他是拉夫堡大学的博士研究生，他的研究重点是开发具有竞争力、高效和创新的绝热压缩空气储能。

几十年来，技术文献将绝热压缩空气储能 (ACAES) 评价为一种潜在的长期储能解决方案。然而，它并没有达到预期的性能指标和广泛的实施。在这里，我们思考每个 ACAES 组件的设计要求和具体挑战。我们使用来自最近的数值、理论和实验研究的证据来定义技术准备水平 (TRL)。最后，我们讨论了未来技术发展的有希望的新方向。
