The deployment of generation systems is being driven by the increasing need to reduce carbon emissions from refining activities. Over the long term, implementing different incentive schemes to limit the sulfur content of motor oil, diesel fuel, and gasoline would promote growth in the generation industry. Highly efficient energy carriers, such as hydrogen, are expected to continue expanding into previously untapped markets. Over the projected period, it is expected that worldwide energy demand will increase by almost two-thirds of its current level.
The market for hydrogen gas covers on-site hydrogen generation systems, the rising adoption of advanced innovations, increased use of hydrogen across multiple industries, and the development of green production technologies. New-age projects related to distributed energy and its usage are expected to boost the market growth. For instance, in January 2024, TotalEnergies and Air Liquide announced the launch of TEAL mobility, a combined venture to form the leader in the distribution of hydrogen in Europe for heavy-duty vehicles.
The U.S. is one of the world's pioneers in the use of sustainable energy solutions across industries such as manufacturing, transportation, and power generation. In December 2006, the Department of Transportation (DOT) and the Department of Energy (DOE) in the U.S. unveiled an initiative to enhance research and development (R&D) and validate technologies for establishing hydrogen infrastructure. Deliverables established by the federal government were included in this plan to support the nation's hydrogen infrastructure development. It was created in accordance with the National Hydrogen Energy Roadmap and Vision. One of the main goals government agencies have set for themselves is the development and installation of energy-efficient, reasonably priced hydrogen stations across the nation. It is anticipated that all of these factors will increase U.S. demand for the hydrogen generation market.
What’s Driving Hydrogen Generation Market Demand?
Rising Industrialization and Infrastructure Development
The increasing urban and industrial expansion is encouraging countries to adopt various power generation methods to fulfill rising energy demand. Additionally, rapid infrastructure development activities and an increasing population across regions such as the Middle East, Africa, and the Asia Pacific. Rising concern regarding clean and sustainable energy use for reducing the dependency on traditional fossil fuels, such as natural gas & crude oil, is supporting the adoption of hydrogen-based energy solutions worldwide. These combined factors are driving demand in the hydrogen generation market.
Shift Toward Sustainable and Clean Energy
A growing focus on the clean energy transition and supportive government policies are influencing the hydrogen generation market. The global energy challenge has increased interest in low-carbon energy sources. Higher investments are being made in the research and development of alternative energy solutions. Sustainability in energy generation involves early-stage use of cleaner technologies due to their long-term environmental and industrial impact. These shifts are positively influencing the demand for hydrogen generation.
Environmental Regulations and Clean Fuel Research
Over the past two decades, increased research into clean fuels and emission-reduction technologies, including the desulfurization of petroleum products, has supported environmental catalysis activities worldwide. Rising air pollution levels and stricter fuel quality regulations, such as those enforced by the U.S. EPA, are influencing the production and distribution of gasoline and diesel fuels. Such regulatory pressure is encouraging the adoption of hydrogen in cleaner energy and industrial applications.
What’s Restraining Hydrogen Generation Market Demand?
Expensive Storage, Transport, and Handling Costs
Nowadays, tanks are the most popular place to store hydrogen for stationary and small-scale mobile applications, either as a gas or a liquid. However, hydrogen storage is only part of the cost challenge. The broader cost challenge also includes transportation, compression, and handling infrastructure. Transporting and storing hydrogen requires the use of high-pressure compression systems and cooling equipment. Specialized logistics are also needed. All of this increases overall operational costs.
The storage tanks used to store hydrogen must have low temperatures, a non-reactive medium, and fast, reversible hydrogen adsorption/desorption that doesn't require heat energy. Meeting these technical requirements makes storage systems capital-intensive. It also limits scalability in large-scale and distributed applications. It requires specialized storage tanks, which tend to have a huge price, creating a major hindrance to the market.
There are energy losses due to the compression or liquefaction of hydrogen when it is transported over long distances. Additional costs are incurred due to the transport vessels or reinforced pipes. When hydrogen molecules are needed, the ammonia stored as hydrogen must be broken down using thermal energy. This adds to conversion and energy expenses. As a result, modified storage and transport systems for hydrogen involve high costs.
In addition, the storage of hydrogen, as well as the expensive hydrogen infrastructure constraints for compression and distribution, have been identified as another major hindrance to the widespread adoption of fuel cells. These factors are expected to continue to hamper the market's growth due to associated costs and scaling issues.
Report Segmentation
