摘要

混合气体-电压氨裂解器(HAVAC)是一种集中式氨裂解制氢的新方法,可提高效率和可扩展性。这种新工艺将可再生电力和自热操作整合在一起,用于裂解蓝氨或绿氨,热效率高达 94% 至 95%。HAVAC 的氨转化率高达 99.4%,氢气产量介于 84% 和 99.5% 之间,氢气纯度为 99.99%,符合 ISO 14687:2019 标准。主要创新包括该工艺可在三种模式下灵活运行:100% 可再生能源电力、100% 空气自热或混合方法。这种多功能性可优化能源利用并适应各种条件。HAVAC 中的气体加热裂解器 (GHC) 通过利用余热有效降低了能源需求。通过使用 Aspen Plus 模拟器建模并根据实验数据进行验证,HAVAC 的经济分析表明,氢气的平准化成本(LCOH)介于每千克-H2 3.80 美元和每千克-H2 6.00 美元之间。该工艺的环境效益包括减少温室气体排放和有效的氮氧化物废物管理。未来的研究重点是扩大规模、降低氨进料成本、优化催化剂和加强废物管理。HAVAC 为推进氢气生产和支持可持续的无碳氢经济带来了巨大希望。本分析所产生的技术和经济数据将有助于决策者和研究人员推动无碳氢经济的发展。

Novel carbon-free innovation in centralised ammonia cracking for a sustainable hydrogen economy: the hybrid air-volt ammonia cracker (HAVAC) process

The hybrid air-volt ammonia cracker (HAVAC) represents a novel approach to centralised ammonia cracking for hydrogen production, enhancing both efficiency and scalability. This novel process integrates renewable electricity and autothermal operation to crack blue or green ammonia, achieving a high thermal efficiency of 94% to 95%. HAVAC demonstrates impressive ammonia conversion rates up to 99.4% and hydrogen yields between 84% and 99.5%, with hydrogen purity of 99.99% meeting ISO 14687:2019 standards. Key innovations include the process's flexibility to operate in three modes: 100% renewable electricity, 100% air autothermal, or a hybrid approach. This versatility optimizes energy use and adapts to varying conditions. The gas heated cracker (GHC) within HAVAC efficiently reduces energy demands by utilizing waste heat. Modelled using the Aspen Plus Simulator and validated against experimental data, HAVAC's economic analysis indicates a levelized cost of hydrogen (LCOH) between $3.80 per kg-H2 and $6.00 per kg-H2. The process's environmental benefits include reduced greenhouse gas emissions and effective NOx waste management. Future research will focus on scaling up, reducing ammonia feed cost, optimizing catalysts, and enhancing waste management. HAVAC offers substantial promise for advancing hydrogen production and supporting a sustainable, carbon-free hydrogen economy. The technical and economic data generated by this analysis will assist decision-makers and researchers in advancing the pursuit of a carbon-free hydrogen economy.
