1. Production Technologies:
a. Using: steam and natural gas to extract hydrogen, steam methane reforming (SMR) is the most used method for producing hydrogen. Even though SMR is common, it is linked to carbon emissions; therefore, the integration of carbon capture and storage (CCS) technology is a major area of continuing study.
b. Electrolysis: Hydrogen and oxygen are separated from water by electrolysis, a process that uses electricity. Primary methods for electrolysis are alkaline and proton exchange membrane (PEM), with PEM becoming more popular because of its versatility and efficiency.
c. Biomass Gasification: This process creates syngas, which is a precursor to hydrogen, from organic resources. Gas cleaning and the availability of feedstock present obstacles to this promising approach for producing hydrogen sustainably.
d. Pyrolysis: For the purpose of producing carbon and hydrogen, pyrolysis uses heat breakdown.
2. Storage Technologies:
a. Compressed Hydrogen Storage: Energy-intensive compression and the requirement for a sturdy storage infrastructure are challenges. High pressure hydrogen gas compression enables storage in tanks.
b. Liquid Hydrogen Storage: Cryogenic storage uses a lot of energy but provides a high energy density. Hydrogen can be liquefied at very low temperatures for compact storage.
