The present work describes the results achieved during a study aiming at the full replacement of the natural gas demand of an integrated hot metal production. This work implements a novel approach using a biomass gasification plant combined with an electrolysis unit to substitute the present natural gas demand of an integrated hot metal production. Therefore, a simulation platform, including mathematical models for all relevant process units, enabling the calculation of all relevant mass and energy balances was created. As a result, the calculations show that a natural gas demand of about 385 MW can be replaced and an additional 100 MW hydrogen-rich reducing gas can be produced by the use of 132 MW of biomass together with 571 MW electricity produced from renewable energy. The results achieved indicate that a full replacement of the natural gas demand would be possible from a technological point of view. At the same time, the technological readiness level of available electrolysis units shows that a production at such a large scale has not been demonstrated yet.

本工作描述了在旨在完全替代综合铁水生产的天然气需求的研究过程中获得的结果。这项工作实现了一种新方法，该方法使用生物质气化装置与电解装置相结合来替代目前的综合铁水生产天然气需求。因此，创建了一个仿真平台，其中包括所有相关过程单元的数学模型，从而能够计算所有相关质量和能量平衡。结果，计算表明，可以替代约385 MW的天然气需求，并且通过使用132 MW的生物质以及571 MW的可再生能源发电，可以生产额外的100 MW富氢还原气体。取得的结果表明，从技术角度来看，完全可以替代天然气需求。同时，可用电解单元的技术准备水平表明尚未证明如此大规模的生产。
