HRL was approached by our client to conduct a techno-economic pre-feasibility study of a low emission hydrogen production project. The objective was to assess various process alternatives for hydrogen (H2) production while reducing the carbon dioxide (CO2) generated during the process.
HRL's Techno-Economic Analysis of Low Emission Hydrogen Production
Challenge
Solution
HRL conducted a comprehensive study that encompassed several key processes, including water gas shift of syngas, acid gas removal, H2 purification and compression, CO2 dehydration and compression. The evaluation focused on CO2 emissions, fuel and utility consumption, and product yield.
Following rigorous analysis, a recommended option was identified, prioritizing low CO2 emissions. The chosen solution achieved near-zero CO2 emissions. Additionally, this option boasted higher product yield and lower water consumption compared to alternatives.
Results
The recommended option emerged as the most promising outcome of the pre-feasibility study, offering significant advantages. The option's utilisation of green-sourced power minimised its carbon footprint. Overall, the selected solution not only addressed the challenge of reducing CO2 emissions but also demonstrated improved efficiency and sustainability in H2 production.
