Hydrogen technology adoption analysis in Africa using a Doughnut-PESTLE hydrogen model (DPHM)
The hydrogen economy requires the right conditions to produce hydrogen by sustainable routes and provide it to local and international markets for suitable applications. This study evaluated the political, economic, social, technological, legal, and environmental (PESTLE) conditions that can be instrumental in adopting hydrogen technologies most effectively by encapsulating aspects relevant to key stakeholders from hydrogen technology developers through to end-users. For instance, the analysis has shown that countries within a government effectiveness index of 0.5 and −0.5 are leading the planning of hydrogen economies through strategic cooperation with hydrogen technology developers. Furthermore, the combination of a Doughnut and PESTLE analysis created a novel approach to assessing the adoption of hydrogen technologies while evaluating the impact of the hydrogen economy. For instance, the estimated ammonia demand in 2050 and subsequent anthropogenic nitrogen extraction rate will be about two and a half times more than the 2009 extraction rate.

基于 Doughnut-PESTLE 氢能模型（DPHM）的非洲氢能技术采纳分析，本研究旨在探讨氢能经济所需的适宜条件，包括通过可持续途径生产氢能并为其在本地和国际市场提供适合应用的场景。研究评估了政治、经济、社会、技术、法律和环境（PESTLE）等条件，这些条件对于最有效地采纳氢能技术具有关键作用，涵盖了从氢能技术开发者到最终用户等关键利益相关者的相关方面。例如，分析表明，政府有效性指数介于0.5和-0.5之间的国家正通过战略合作为氢能技术开发者制定氢能经济规划处于领先地位。此外，Doughnut 与 PESTLE 分析的结合，为评估氢能技术的采纳及氢能经济的影响提供了一种创新的方法。例如，预计到2050年氨的需求量及随之而来的人为氮提取速率将是2009年的两倍半。
