Hydrogen as Sustainable and Green Energy Resource

Abstract

Hydrogen is a clean fuel that can be used as the major energy resource. Hydrogen can be produced from various renewable and sustainable sources. Cost of hydrogen is high when it is produced from alternative sources. Hydrogen can be utilized as an energy source when it can be produced from cheap and renewable source. Emphasis should be given to those methods that have a low CO 2 footprint. Purification, transportation, and storing are important aspects that can be emphasized. Hydrogen is used as fuel in internal combustion engine ( ICE ) and fuel cell electric vehicle ( FCEV ). The cost of FCEV is higher than car with ICE . However, the FCEVs have more fuel efficiency than ICE car. Suitable materials should be developed for storing hydrogen in both liquid and compressed gas form. Lightweight, high mechanical strength, and low‐cost materials are preferred for this purpose. Safety issues should be taken care for production, fueling, and transportation systems.
