Abstract

Media discourses help shape the visibility and legitimacy of energy transition pathways in the public sphere. This study examines how Brazilian mainstream newspapers framed green hydrogen and assesses the alignment of these narratives with the energy trilemma: energy security, environmental sustainability, and social accessibility. We analyzed 286 articles published by G1 and Estadão between January 2020 and June 2023, combining BERTopic-based topic modeling, supervised LDA, and qualitative contextual interpretation. The findings show that media coverage addressed all dimensions of the energy trilemma but prioritized financing, investment, production costs, regulation, and export opportunities. Social accessibility, environmental impacts, territorial conflicts, and the distributive implications of water and land use remained comparatively marginal. Brazilian media therefore tended to portray green hydrogen as a market-oriented and export-driven opportunity rather than as a comprehensive socio-ecological transition. These findings highlight the limits of mainstream media framing and its insufficient attention to energy and climate justice.

巴西媒体中的绿色氢：能源三难困境的主导叙事和缺失维度

媒体话语有助于塑造公共领域能源转型路径的可见性和合法性。本研究考察了巴西主流报纸如何构建绿色氢，并评估了这些叙事与能源三难困境的一致性：能源安全、环境可持续性和社会可及性。我们分析了G1和estad在2020年1月至2023年6月期间发表的286篇文章，结合了基于bertopic的主题建模、监督LDA和定性上下文解释。研究结果表明，媒体报道涉及能源三难困境的所有方面，但优先考虑融资、投资、生产成本、监管和出口机会。社会可及性、环境影响、领土冲突以及水和土地利用的分配影响仍然相对次要。因此，巴西媒体倾向于将绿色氢描述为以市场为导向和出口驱动的机会，而不是全面的社会生态转型。这些发现突出了主流媒体框架的局限性，以及对能源和气候正义的关注不足。陈志强，陈志强。2015。沙特能源转型：宏观经济权衡的ARDL分析。政治与政策53，no。6: e70085。https://doi.org/10.1111/polp.70085。kilin - pala, p.b. 2021。能源独占安全的途径：能源安全理论与现实主义的主导地位。政治与政策49，不。3: 771 - 794。https://doi.org/10.1111/polp.12411。塞加托，C.
