How Does a Hydrogen Renewable Energy System Work?
The Hydrogen Renewable Energy System is a sophisticated process that harnesses the potential of hydrogen gas as a clean and sustainable energy source. This intricate system involves several essential steps to ensure efficient production, storage, conversion, and distribution of hydrogen energy.
- Hydrogen Production
At the heart of the system lies the hydrogen production phase. There are various methods employed to obtain hydrogen gas, each offering unique advantages. One such method is electrolysis, which involves using electricity generated from renewable sources like solar or wind to split water molecules into hydrogen and oxygen. Additionally, other techniques like steam methane reforming and biomass gasification can also be utilized to produce hydrogen from different feedstocks.
- Hydrogen Storage
Once produced, the generated hydrogen needs to be stored effectively to guarantee a steady and reliable energy supply. Specialized tanks or containers are used for this purpose, enabling the safe storage of hydrogen gas. The efficient storage of hydrogen is crucial, particularly during times when renewable energy sources may not be consistently available.
- Fuel Cell Conversion
The stored hydrogen is then fed into a fuel cell, where an electrochemical process occurs. Within the fuel cell, hydrogen combines with oxygen extracted from the air to create electricity, water, and heat. This process, known as fuel cell conversion, is highly efficient and emission-free, making it an environmentally friendly energy conversion method. The electricity produced in this step can be utilized to power a wide range of applications, including residential and commercial buildings, vehicles, and various industrial processes.
- Energy Distribution
The electricity generated by the fuel cell can be utilized directly at the point of generation or integrated into the existing power grid for broader distribution. This integration enables surplus hydrogen energy to be shared and utilized in other locations, thereby increasing the system's overall efficiency and providing a scalable energy solution. This aspect of the process allows for the establishment of a comprehensive hydrogen energy infrastructure, contributing to the development of a cleaner and more sustainable energy landscape.

The world's fossil fuel economy is depleting due to the non-renewable nature of fossil fuels, which drives consuming nations to control fuel supply regions.
Hydrogen, a promising alternative energy source, aids in global decarbonization and is increasingly used in data centers and hospitals as backup power, with companies like Microsoft testing hydrogen-powered generators.
Hydrogen fuel cells, initially developed by NASA, provide efficient mobile power for up to 13 hours. Additionally, hydrogen is crucial in the chemical industry for producing fertilizers, ammonia, and petroleum products, and is being explored for steel-making to reduce pollution.
Most hydrogen today is produced through steam methane reforming, creating hydrogen along with carbon monoxide and dioxide, and despite its limitations, hydrogen is valuable for transportation and power generation.
The Green Hydrogen Production Cost
Green hydrogen is a highly sustainable and clean energy source that has seen significant growth in demand since the 1970s, with current global consumption of around 70 million tonnes per year.
Despite its benefits and cost-effectiveness, its capacity as a baseload operation is limited. The production cost of hydrogen depends on several factors, including the size of the installation and the production pathway.
While centralized production is common, distributed production is seen as more viable during market development due to lower transportation costs. Companies like Nel ASA and Petroliam Nasional Bhd.
are working to reduce production costs to $1-$2 per kilogram by 2025. Although initial costs are high, the cost curve is expected to decline with increased investment and the availability of low-carbon electricity sources, ultimately driving the profitability of green hydrogen projects.
Infrastructure
In a rapidly growing global energy industry, hydrogen is proving to be a highly viable and cost-effective source of renewable energy. A growing demand for the gas has led to a rapid growth of the production of hydrogen. Currently, over 6% of global natural gas and 2% of global coal are used for the production of hydrogen. This process is responsible for emitted CO2 of up to 830 million tonnes per year – the equivalent to the emissions produced by the United Kingdom and Indonesia combined.
The recent federal funding for hydrogen research and development in the recently passed infrastructure bill is raising questions about the future of this fuel and elevating its role in state carbon plans. In addition, advocates argue that hydrogen's potential role in reducing carbon emissions in heavy industry and long-haul transportation could be critical in achieving the goals set by the Paris Climate Agreement. In addition, the recent investment in U.S. hydrogen research shows that hydrogen is a promising fuel that is essential in a low-carbon future.
Currently, hydrogen is largely used in the petroleum refining and chemical processing industries. The key piece of infrastructure needed for hydrogen production is the electrolyzer, which is a process in which hydrogen is converted from a liquid into a gas. There are two basic types of electrolyzers: solid polymer electrolyzers and alkaline water electrolyzers. Solid oxide electrolyzers are currently being used in space and are expected to eventually replace PEM devices. In Iowa, renewable H2 is already competitive with conventional fuels.
State and regional efforts to build hydrogen hubs are underway to make hydrogen more accessible to consumers. The IIJA program will provide $8 billion for hydrogen hubs and has created a significant opportunity to leverage existing infrastructure and assets. The US Department of Energy's Office of Clean Energy Demonstrations is working to facilitate hydrogen hub development. Further, individual states are seeking hydrogen hubs to facilitate the economic development of hydrogen. However, state and regional governments will need tools to identify opportunities for hydrogen hubs and connect them with potential partners.
