Industrial gases, such as nitrogen, oxygen, and hydrogen, play an essential role in a wide range of sectors, including chemicals, metals, energy, and healthcare. Due to the high energy intensity of the production processes, the industrial gas industry is constantly exploring opportunities to reduce its energy cost. In addition, with the urgent need for decarbonization, there has been a strong push for clean technologies, especially in the hydrogen business. In this work, we review the existing literature on energy-aware optimization for the industrial gas industry, focusing on decision-making at the enterprise level in atmospheric gases and hydrogen supply chains. Case studies drawn from previous industry-university research collaborations are presented to highlight the potential benefits of demand response. Moreover, we provide a perspective on opportunities and challenges in clean energy for this industry, emphasizing the need to transition to more sustainable and agile industrial gas supply chains.

工业气体，如氮气、氧气和氢气，在化学品、金属、能源和医疗保健等广泛领域发挥着重要作用。由于生产过程的高能源强度，工业气体行业正在不断探索降低能源成本的机会。此外，随着脱碳的迫切需求，清洁技术得到了大力推动，特别是在氢业务方面。在这项工作中，我们回顾了有关工业气体行业能源感知优化的现有文献，重点关注大气气体和氢气供应链的企业级决策。展示了从以前的产学研合作中提取的案例研究，以突出需求响应的潜在好处。而且，
