The Impracticality of Hydrogen as a Viable Fuel Source

Hydrogen has been touted as a potential clean and renewable fuel source, with proponents advocating its use in various industries, including transportation and energy production. However, a closer examination reveals that hydrogen, despite its environmental appeal, presents several impracticalities that hinder its widespread adoption. This article discusses the inherent impracticality of hydrogen as a viable, fuel source. The author concludes it will only be used for niche purposes as we transition to a cleaner economy.



Production Challenges: 

Hydrogen is not freely available in its elemental form; it must be extracted from other compounds. The most common method, steam methane reforming, relies on natural gas, releasing carbon dioxide in the process. Alternatives like electrolysis, which uses electricity to split water into hydrogen and oxygen, are energy-intensive. Until the production of hydrogen becomes more sustainable, its claim as a clean fuel source remains questionable. 

  

Energy Loss in Production: 

The process of producing hydrogen involves significant energy losses. Whether derived from natural gas or water through electrolysis, the overall efficiency is low. The energy expended in extraction, transportation, and compression of hydrogen often exceeds the energy recovered when it is used as a fuel. This inefficiency undermines the environmental benefits and economic viability of hydrogen as a mainstream energy source. 

  

Storage and Transportation Challenges: 

Hydrogen has a low energy density, requiring large storage volumes or high-pressure conditions for compact storage. The infrastructure needed for the transportation and distribution of hydrogen at such conditions is costly and poses safety concerns. Additionally, hydrogen tends to leak easily, presenting challenges for long-term storage and transportation. 

  

Infrastructure Investment: 

Building a hydrogen infrastructure, including production facilities, pipelines, and refueling stations, demands a substantial financial investment. This raises questions about the feasibility and practicality of diverting funds from other, more established renewable energy sources with proven track records, such as solar and wind, to support hydrogen initiatives.




Limited End-Use Efficiency: 

When used in fuel cells to generate electricity, hydrogen faces further losses in efficiency. The conversion process from hydrogen to electricity in fuel cells is not as efficient as direct electrical generation. This lower end-use efficiency means that a larger quantity of hydrogen is required to produce the same amount of usable energy compared to more established alternatives. 

  

Environmental Impact of Production: 

Despite being considered a "clean" fuel, the production of hydrogen from natural gas releases carbon dioxide, a greenhouse gas contributing to climate change. Even electrolysis, touted as a green production method, relies on electricity that may not be sourced from renewable resources. Until hydrogen production methods become more environmentally friendly, its role in combating climate change remains questionable. 

  

Competition with Established Technologies: 

Hydrogen faces stiff competition from well-established renewable energy technologies such as solar and wind. These alternatives have proven track records, lower costs, and more efficient energy production methods. Investing in hydrogen diverts attention and resources from the further development and implementation of these readily available and effective technologies. 



While hydrogen may seem like an attractive solution for a clean energy future, its impracticalities make it an inefficient and costly alternative compared to more established renewable energy sources. The challenges in production, storage, transportation, and overall energy efficiency significantly hinder its viability as a mainstream fuel source. As the world seeks sustainable solutions to combat climate change, it is crucial to focus on technologies that offer practical, economically viable, and environmentally friendly alternatives. At present, hydrogen falls short of meeting these criteria, and greater emphasis should be placed on advancing technologies with proven effectiveness in achieving a greener and more sustainable future.
