Lessons for Direct Air Capture from the history of Ammonia Synthesis

A collection of historical data used in our article, "Lessons for Direct Air Capture from the History of Nitrogen Synthesis: High rates of deployment are possible, with strong support. This dataset is intended to provide transparency on the historical research underpinning our work. The attached Excel file includes the following sheets: 1) An overview sheet listing and describing all the subsequent sheets 2) A long list of candidate historical analogues, showing how they were eliminated from consideration as a historical analogue for direct air capture 3) A short list of candidate historical analogues, showing the data that was used to construct a time series of historical capacity for each of them. 4) A list of nitrogen synthesis facilities built around the world from 1905 to 1930. This data was compiled from historical primary sources, and was used to create time series documenting the number of plants and total capacity in all the countries operating nitrogen synthesis industries at this time 5) A collection of time series data showing the growth of the nitrogen industry in every country on earth, compiled from various historical sources and statistical repositories 6) A data series providing a single continuous time series for synthetic ammonia production from 1913 to 1922, which is then projected into a scenario for the possible future growth of direct air capture, starting in 2024 7) An analysis of the progress of direct air capture and ammonia synthesis technologies through the technological readiness levels, based on historical sources 9) A qualitative chronology of the history of ammonia synthesis around the world, categorized by country and by the arenas of cause and effect that apply to each event. Includes citations for every event listed. This is the basis of the qualitative narrative presented in our article. 10) A list of assumptions underpinning the data in all the other sheets, as well as some miscellaneous notes 11) A bibliography documenting all the sources used in the rest of the dataset本数据集为本论文《从氮合成历史汲取直接空气捕集（Direct Air Capture）的经验：依托强力支撑可实现高规模部署》所用的历史数据集合，旨在为本研究依托的历史研究内容提供透明度。随附的Excel文件包含以下工作表： 1）总览工作表：列出并说明后续所有工作表的内容 2）候选历史类比物长列表：展示这些候选类比物为何被排除在直接空气捕集的历史类比研究范围之外 3）候选历史类比物短列表：展示用于构建各候选类比物历史装机容量时间序列的相关数据 4）1905年至1930年全球氮合成设施列表：本数据集从历史一手资料汇编而来，用于生成时间序列，记录彼时开展氮合成产业的所有国家的工厂数量与总装机容量 5）全球各国氮产业发展时间序列数据集：从各类历史资料与统计资料库汇编而来，展示全球各国氮产业的发展历程 6）合成氨产量连续时间序列数据集：涵盖1913年至1922年的合成氨产量连续时间序列，并以此为基础推演得到2024年起直接空气捕集未来可能的增长场景 7）技术就绪水平分析：基于历史资料，分析直接空气捕集与合成氨技术的发展历程，按技术就绪等级展开 9）合成氨历史全球编年定性研究：按国家与各事件对应的因果维度分类，包含所列全部事件的引用来源，为本论文呈现的定性叙事奠定基础 10）通用假设与杂项说明列表：列出支撑所有其他工作表数据的各项假设，以及部分杂项备注 11）参考文献列表：记录本数据集其余部分所用的全部资料来源
