Photobiological hydrogen production through algae (including green algae and cyanobacteria) is one of the most promising ways to obtain green hydrogen energy due to its outstanding light-harvesting and energy conversion efficacy. However, the sustainability and cost essentially impede its large-scale commercial production. This study aims to bridge this gap, present a blueprint for sustained and sustainable bioH2 production, and provide scientists and policymakers with a reference and foundation to evaluate its economic feasibility when applied locally. Evaluation is based on a simplified assumption of functioning algae as living ‘solar panels’. By revisiting the current literature, recent advancements in this technology are identified, offering potential solutions to overcome the issues. A combination of a promising algal bioH2 generating method with its derivative concept-design algae culturing model was compared with the largest photovoltaic electrolysis H2 plant in the world hitherto to show both pros and cons of these two methods. A global spatiotemporal dynamic map and scalability analysis were performed to demonstrate the potential of algal bioH2 production among various locations.

基于藻类的光生物制氢的全球潜力
通过藻类（包括绿藻和蓝藻）进行光生物制氢是获得绿色氢能的最有希望的方法之一，因为它具有出色的光捕获和能量转换效率。然而，可持续性和成本本质上阻碍了其大规模商业生产。本研究旨在弥合这一差距，提出可持续和可持续 bioH 2的蓝图生产，并为科学家和决策者提供参考和基础，以评估其在当地应用时的经济可行性。评估是基于将功能藻类作为活的“太阳能电池板”的简化假设。通过重新审视当前的文献，确定了该技术的最新进展，为克服这些问题提供了潜在的解决方案。将有前途的藻类 bioH 2生成方法与其衍生的概念设计藻类培养模型相结合，与迄今为止世界上最大的光伏电解 H 2工厂进行了比较，以显示这两种方法的优缺点。进行了全球时空动态图和可扩展性分析，以证明藻类 bioH 2的潜力不同地点之间的生产。
