Hydrogen has gained significant attention as a versatile and sustainable energy carrier, with numerous use cases across various sectors. In this response, we will explore the most lucrative use cases for hydrogen and highlight the sectors that are willing to pay a premium for its applications, specifically in chemicals and industry, automotive, and aerospace/defense.
Chemicals and Industry:
Indeed, hydrogen is a versatile and important element in the chemicals and industry sector, and it offers several lucrative use cases. Here are some of the key ways in which hydrogen is utilized in these industries:
- Ammonia Production:
Ammonia (NH3) is a vital component of fertilizers, and its production heavily relies on hydrogen. The Haber-Bosch process, which was developed in the early 20th century, is the primary method used to synthesize ammonia. This process involves the reaction of nitrogen (N2) from the air with hydrogen (H2) under high pressure and temperature, facilitated by iron-based catalysts. Here’s why hydrogen is integral to this process.
- Fertilizer Demand: As the global population continues to grow, the demand for food production increases, driving up the need for fertilizers. Ammonia is a key ingredient in nitrogen-based fertilizers, which are essential for crop cultivation to meet this demand.
- Hydrogen as a Feedstock: Hydrogen is a feedstock for the production of ammonia. It serves as the source of hydrogen atoms that combine with nitrogen to form ammonia molecules. As such, any increase in fertilizer demand directly correlates with an increased demand for hydrogen.
- Methanol Production:
Methanol (CH3OH) is a versatile and widely used chemical in various industries, and hydrogen plays a crucial role in its production. There are multiple methods for producing methanol, but one common approach is the hydrogenation of carbon monoxide (CO) or carbon dioxide (CO2). Here’s why hydrogen is essential in methanol production:
- Diverse Applications: Methanol is a valuable building block for the production of numerous chemicals and materials. It’s used in the automotive industry as a fuel or fuel additive, in the production of paints, adhesives, and construction materials, and even as an antifreeze.
- Hydrogenation Process: In methanol production, hydrogen is used to reduce carbon monoxide or carbon dioxide to create methanol. This reaction, known as the hydrogenation process, relies on hydrogen as a reducing agent.
- Environmental Considerations: The production of methanol from renewable hydrogen and carbon dioxide capture can be part of a sustainable and low-carbon solution, contributing to the reduction of greenhouse gas emissions.
- Petroleum Refining:
Hydrogen plays a critical role in petroleum refining, particularly in processes aimed at producing cleaner and higher-quality petroleum products. Here’s why hydrogen is essential in petroleum refining:
- Sulfur Removal: In the refining of crude oil, one of the primary objectives is to remove impurities, particularly sulfur compounds, which can result in air pollution when burned. Hydrogen is used in hydrodesulfurization (HDS) processes to break sulfur bonds and convert sulfur compounds into hydrogen sulfide, which can then be easily removed.
- Cleaner Fuels: The demand for cleaner fuels with lower sulfur content is driven by environmental regulations. Hydrogen enables refineries to meet these regulatory requirements and produce gasoline and diesel with reduced sulfur levels, resulting in less pollution and improved air quality.
- Hydrocracking: In hydrocracking processes, hydrogen is used to break down heavy hydrocarbons into lighter fractions, such as gasoline and diesel, which are more valuable and in higher demand.
- Product Quality Improvement: The addition of hydrogen to various refining processes can enhance the quality of petroleum products, increasing their market value.

Automotive Sector:
Hydrogen holds great potential in the automotive industry, particularly for fuel cell electric vehicles (FCEVs). FCEVs utilize hydrogen fuel cells to produce electricity, providing a viable alternative to conventional internal combustion engines. Some lucrative use cases include.
- Fuel Cell Vehicles:
FCEVs are a form of clean, zero-emission transportation, which makes them particularly attractive for countries and regions aiming to reduce greenhouse gas emissions and combat air pollution. FCEVs are known for their long-range capabilities. They can travel greater distances on a single tank of hydrogen compared to many battery electric vehicles (BEVs), making them suitable for applications where extended ranges are critical, such as commercial transport and long-haul freight.
One of the significant advantages of FCEVs is their quick refueling times. Refilling a hydrogen tank takes minutes, similar to refueling a conventional gasoline or diesel vehicle. Many governments are actively incentivizing the adoption of clean energy vehicles, including FCEVs.
- Hydrogen Refueling Infrastructure:
The availability of a robust hydrogen refueling infrastructure is a critical factor in the widespread adoption of FCEVs. Without a reliable network of refueling stations, consumers and businesses may be hesitant to invest in hydrogen-powered vehicles.
Companies and investors involved in the development of hydrogen refueling stations and distribution networks can capitalize on the growing demand for hydrogen fuel. Hydrogen production using renewable energy sources further enhances the environmental benefits of FCEVs and their refueling infrastructure. The establishment of hydrogen refueling stations and distribution networks can have a positive economic impact on the regions where they are developed.
