Reduction of carbon emissions from conventional gray Hydrogen ($H_2)$ production is a promising option in moving towards much greener $H_2$ generation. To minimise carbon emissions and improve plants’ efficiencies of conventional gray $H_2$ production, this study focused on process simulation of hybrid CSP, catalytic Methane (${\mathit{CH}}_4$) and biomass pyrolysis and Water ($H_{2}O$) electrolysis plants with 1000 °C HTF output temperature. This integrated system differs from current pyrolysis and electrolysis technologies for $H_2$ production because of the involvement of CSP as a thermal energy source; the use of part of recovered heat from the reactor to power downstream units including thermolysis of Sulphuric Acid ($H_{2}S{O}_4$) and steam generation for both $H_{2}O$ electrolysis and Rankine cycle; the use of $H_{2}O$ as a reaction media and carbon looping to promote biomass decomposition; anodic oxidation of ${\mathit{SO}}_2$ in AEC to promote hydrogen evolution reaction. In that regard, CSP systems were modelled and simulated in SAM and MATLAB software. The output result of the simulated CSP system got exported to the Simulink to feed simulated ${\mathit{CH}}_4$ and biomass pyrolysis coupled with TES and Rankine cycle from Aspen plus. In addition, simulated thermal disassociation of $H_{2}S{O}_4$, electrolysis of $H_{2}O$ with SOEC and AEC from Aspen plus was also exported to the Simulink to feed the CSP system. Both integrated systems were fed with ${\mathit{CH}}_4$ as the working fluid of the solar furnace. About $1.7/kg is estimated to be a $H_2$ selling price for simulated pyrolysis of ${\mathit{CH}}_4$ and biomass plant which is cheaper than SMR with a CCS system. While between 4.6 and 10.48 is also estimated to be a $H_2$ selling price for another simulated ${\mathit{CH}}_4$ pyrolysis and $H_{2}O$ electrolysis. Just like existing CSP systems for electricity generation, both simulated hybrid systems generate electricity for up to 200 min in the absence of the Sun. Similar to SMR with a CCS system, $C{O}_2$ by-product from biomass pyrolysis was captured. Due to coking issues related to catalytic pyrolysis, noncatalytic pyrolysis of ${\mathit{CH}}_4$ was investigated. Results of the research work show that a return on investment within a period of 6 years is possible with the adoption of these new innovative technologies while reducing carbon footprints in $H_2$ generation plants.

减少传统灰氢（$H_{\mathrm{2个}})$生产是迈向更环保的一个有前途的选择$H_{\mathrm{2个}}$一代。最大限度地减少碳排放并提高工厂传统灰色的效率$H_{\mathrm{2个}}$生产，本研究的重点是混合 CSP、催化甲烷（${\mathit{CH}}_{\mathrm{4个}}$) 和生物质热解和水 ($H_{\mathrm{2个}}欧$) 具有 1000 °C HTF 输出温度的电解设备。该集成系统不同于目前的热解和电解技术$H_{\mathrm{2个}}$由于 CSP 作为热能源的参与而生产；使用从反应器回收的部分热量为下游装置提供动力，包括硫酸的热解（$H_{\mathrm{2个}}\mathrm{小号}{欧}_{\mathrm{4个}}$) 和两者的蒸汽产生$H_{\mathrm{2个}}欧$电解和朗肯循环；指某东西的用途$H_{\mathrm{2个}}欧$作为反应介质和碳循环以促进生物质分解；阳极氧化${\mathit{所以}}_{\mathrm{2个}}$在 AEC 中促进析氢反应。在这方面，CSP 系统在 SAM 和 MATLAB 软件中进行建模和仿真。仿真 CSP 系统的输出结果被导出到 Simulink 以提供仿真${\mathit{CH}}_{\mathrm{4个}}$生物质热解与 Aspen plus 的 TES 和朗肯循环相结合。此外，模拟的热解离$H_{\mathrm{2个}}\mathrm{小号}{欧}_{\mathrm{4个}}$, 电解$H_{\mathrm{2个}}欧$来自 Aspen plus 的 SOEC 和 AEC 也被导出到 Simulink 以提供 CSP 系统。两个集成系统都提供了${\mathit{CH}}_{\mathrm{4个}}$作为太阳炉的工作流体。大约 1.7 美元/公斤估计是$H_{\mathrm{2个}}$模拟热解的售价${\mathit{CH}}_{\mathrm{4个}}$和生物质发电厂，比带有 CCS 系统的 SMR 便宜。而在 4.6 和 10.48 之间也估计是$H_{\mathrm{2个}}$另一个模拟的售价${\mathit{CH}}_{\mathrm{4个}}$热解和$H_{\mathrm{2个}}欧$电解。就像现有的 CSP 发电系统一样，这两个模拟混合系统在没有太阳的情况下最多可发电 200 分钟。类似于带有 CCS 系统的 SMR，$C{欧}_{\mathrm{2个}}$捕获了生物质热解的副产品。由于与催化热解相关的焦化问题，非催化热解${\mathit{CH}}_{\mathrm{4个}}$被调查了。研究工作的结果表明，采用这些新的创新技术，同时减少碳足迹，有可能在 6 年内收回投资$H_{\mathrm{2个}}$世代植物。
