English
This study proposes a large-scale system using floating offshore photovoltaic (FOPV) in equatorial waters to produce green hydrogen and ammonia, transported worldwide via pipelines. It also models atmospheric CO2 removal to revert temperature rise to 1960s levels by 2100. Numerical analysis suggests early implementation reduces costs and health hazards.

📄 Abstract（原文）
<title>Abstract</title> <p> Global warming poses a serious threat to humanity and ecosystems; however, no fundamental solution has yet been found. This study examined strategies to overcome the challenges currently facing solar and wind power generation, such as limited installation space, reduced power grid inertia, and large-scale energy storage. A floating offshore photovoltaic (FOPV) power plant is proposed for the vast equatorial waters. This power plant will produce green hydrogen and synthesize green fuel ammonia, a hydrogen energy carrier. This enables worldwide transportation and storage via pipelines, minimizing losses. Furthermore, we constructed a model that removes CO <sub>2</sub> eq (with over 36,000 Gt cumulative in the atmosphere) and restores the temperature rise to the levels of the 1960s. Based on the proportional relationship between cumulative CO <sub>2</sub> eq emissions and temperature rise from 1850 to 2024, numerical analyses were conducted on global warming from 1850 to 2100 under four scenarios. The results showed that early implementation reduces the cost of restoring temperature rise levels to the 1960s and mitigates health hazards. Furthermore, because fuel costs are zero, the cost of electricity—including CO <sub>2</sub> eq removal—could be lower than current levels. Although the model proposed in this study requires validation testing for practical implementation, it holds the potential to become an effective energy production model with global influence in the transition to green energy that is sustainable for the duration of the Sun’s lifespan. </p>
