dc.description.abstractA shift to renewable energy sources is crucial to mitigating climate change. Fossil fuels, such as petroleum, natural gas, and coal, mainly contribute to the economy’s growth. However, their use is also the main contributor to global warming. According to the IPCC report, in 2019, the combined energy supply, industry, and transport sectors represented 73% of the total net anthropogenic emissions, which means approximately 42.7 GtCO2 was released into the atmosphere by these sectors. Green Hydrogen (GH), produced from the electrolysis of water, has the potential to play a significant role in reducing CO2 emissions from fossil fuel systems. Additionally, GH can serve as an intersectoral bridge by storing and utilizing intermittent renewable energy sources (such as wind and solar) for later use in the energy supply, industry, and transport sectors. Following the production of GH, it can be injected into existing natural gas grids (NGG) for cost-effective transportation, thus eliminating the need for extensive infrastructure investments. However, when GH is blended into the NGG, it is necessary to recover and purify it to a high purity level to facilitate applications such as fuel cells (H2 > 99.97%). One challenge associated with separating and purifying GH blended in NGG is the low H2 feed concentration (<20%), which is significantly lower than that required for traditional H2 adsorption purification processes, for example, H2 produced from steam methane reforming (>70%). In this work, we develop a conceptual dual-stage vacuum pressure swing adsorption (VPSA) process to separate and purify H2 blended into the natural gas grids with low H2 feed concentration (<20%).pt_PT
