Abstract

Hydrogen is essential for achieving net-zero emissions by 2050, acting as both an energy carrier and source. It can store renewable energy, decarbonize difficult sectors, and serve as a zero-carbon feedstock. Conventional hydrogen production methods, such as natural gas reforming, inherently produce CO2. Electrolysis, though CO2 free during operation, can still contribute to emissions through the construction of the energy source and electrolyzer; however, using surplus renewable energy that would otherwise be wasted can offset this. In situ hydrogen generation from underground fossil hydrocarbons presents a compelling alternative. This method produces hydrogen directly within geological formations, using existing fossil fuel resources and infrastructure while keeping CO2 sequestered underground, thus minimizing environmental impact and reducing the need for extensive surface processing. Our research examines various in situ techniques, including thermochemical and biological processes, showcasing their potential to enhance current hydrogen production methods. Despite its promise, this approach faces significant challenges and requires extensive research to overcome these hurdles. Addressing these challenges is crucial for integrating this method into the global energy transition, potentially reducing the carbon footprint of hydrogen production and advancing toward cleaner energy systems. This paper highlights the necessary steps and the long path ahead to make in situ hydrogen generation a viable and sustainable solution.
从地下化石碳氢化合物就地制氢
氢作为能源载体和来源,对于到2050年实现净零排放至关重要。它可以储存可再生能源,使困难部门脱碳,并作为零碳原料。传统的制氢方法,如天然气重整,本身就会产生二氧化碳。电解虽然在操作过程中没有二氧化碳,但仍然可以通过能源和电解槽的建设来促进排放;然而,使用多余的可再生能源,否则会被浪费,可以抵消这一点。从地下化石碳氢化合物中就地制氢是一个令人信服的选择。这种方法利用现有的化石燃料资源和基础设施,直接在地质构造中生产氢气,同时将二氧化碳封存在地下,从而最大限度地减少对环境的影响,减少了对大量地面处理的需求。我们的研究考察了各种原位技术,包括热化学和生物过程,展示了它们增强当前制氢方法的潜力。尽管前景光明,但这种方法面临着重大挑战,需要广泛的研究来克服这些障碍。解决这些挑战对于将这种方法整合到全球能源转型中至关重要,这可能会减少氢气生产的碳足迹,并向更清洁的能源系统迈进。本文强调了使原位制氢成为可行和可持续解决方案的必要步骤和漫长道路。
