Barriers to Implementing Green Hydrogen in the Energy Mix

Barriers to Implementing Green Hydrogen in the Energy Mix

There are several barriers to introducing green hydrogen into the energy mix, including high technology costs, a lack of a global supply chain, and a lack of awareness about its benefits.

However, green hydrogen offers tremendous potential in the future of energy, and when combined with battery storage systems, grid-scale hydrogen storage will allow renewable energy sources to be used to their maximum capacity without curtailing them.

Let's explore the barriers to implementing green hydrogen.

What is Green Hydrogen?

Hydrogen is the lightest and most abundant element in the universe, making it an attractive candidate for sustainable energy production. Green hydrogen is produced through the process of electrolysis, where electricity generated from renewable sources, such as wind, solar, or hydropower, is used to split water (H2O) into its constituent elements – hydrogen (H2) and oxygen (O2).

Unlike gray hydrogen, which is produced from natural gas using steam methane reforming (SMR), green hydrogen does not release carbon dioxide (CO2) during the production process. This makes green hydrogen a clean, zero-emission fuel with vast potential to decarbonize various sectors.

Understanding The Electrolysis Process

The production of green hydrogen relies on the electrolysis of water. In this process, water is separated into its constituent elements by passing an electric current through it. The electrolysis cell consists of an anode and a cathode separated by an electrolyte. When a direct current is applied, hydrogen ions (H+) are attracted to the cathode, where they gain electrons to form hydrogen gas. Meanwhile, oxygen ions (O2-) migrate to the anode, where they release electrons to form oxygen gas.

Electrolysis can be carried out through different methods, including alkaline electrolysis, polymer electrolyte membrane (PEM) electrolysis, and solid oxide electrolysis cells (SOEC). Each of these methods has its advantages and is suitable for different applications based on factors such as efficiency, scale, and operating conditions.

Advantages of Green Hydrogen

Green hydrogen, the revolutionary clean energy source, holds immense potential and boasts a myriad of advantages that position it as a crucial player in the transition towards a sustainable energy future. By harnessing renewable resources, it offers a range of benefits that have far-reaching implications for combating climate change and promoting a greener, more sustainable world.

Zero Emissions

One of the most significant advantages of green hydrogen is its impeccable environmental track record. Unlike conventional hydrogen production methods, which release substantial amounts of CO2 into the atmosphere, the production of green hydrogen involves a process known as electrolysis. During electrolysis, water is split into hydrogen and oxygen using renewable electricity sources like wind, solar, or hydro power. This process emits no harmful greenhouse gases, effectively curbing the carbon footprint and helping combat climate change.

Energy Storage

The potential of hydrogen as an energy storage medium cannot be overstated. Renewable energy sources, such as solar and wind, often suffer from intermittency, meaning they produce power inconsistently based on weather conditions and other factors. However, green hydrogen acts as a bridge between renewable energy generation and consumption by enabling efficient energy storage. Excess renewable energy can be used to produce hydrogen through electrolysis during periods of surplus, and the stored hydrogen can be converted back into electricity when demand rises or when renewable sources are not available, effectively stabilizing the grid and enhancing energy security.


Green hydrogen's versatility is another key advantage that makes it a game-changer in the sustainable energy landscape. It serves as a flexible energy carrier, easily adaptable to diverse sectors. In transportation, green hydrogen can power fuel cell vehicles, providing an emissions-free alternative to conventional internal combustion engines. The industrial sector can leverage green hydrogen as a clean feedstock for various processes, reducing its carbon footprint. Additionally, in the heating and power generation sectors, it can be utilized as a renewable fuel to displace fossil fuels and decrease greenhouse gas emissions.

Reduction of Fossil Fuel Dependence

A paramount benefit of green hydrogen lies in its potential to liberate societies from their dependence on non-renewable fossil fuels. As a clean substitute, green hydrogen can replace traditional fossil fuels in a multitude of applications, ranging from transportation and industrial processes to power generation and heating. By embracing green hydrogen as an alternative energy source, societies can significantly reduce their reliance on finite fossil fuel resources, thereby fostering energy security and sustainability.

Green Hydrogen Renewable energy

As the world grows increasingly reliant on clean energy sources, a key challenge for hydrogen is establishing a reliable infrastructure. The rapid growth of hydrogen and renewable energy resources has led to concerns about their cost, and a lack of available infrastructure has hindered the widespread adoption of the technology.

The IEA has identified four hydrogen value chains that have the potential to meet the needs of the U.S. market. These innovative technologies can be combined with fossil energy assets to produce a cleaner alternative.

Hydrogen is a secondary source of energy and is used as a carrier to store energy generated from other resources. It can be obtained from hydrocarbons, biomass, and water. It is a clean-burning fuel and is a good choice for a fuel cell as it produces electricity and heat and water vapor as a byproduct.

These properties make it a viable alternative to natural gas and fossil fuels. Despite its cost, hydrogen is a highly efficient alternative to other forms of energy.

The chemical industry is at the core of the modern economy, providing essential commodities and materials that support economies and human needs. It is projected that by 2030, the chemical industry will be the world's largest oil producer, and it is crucial to ensure adequate supplies of oil.

As hydrogen is three times more energy dense than natural gas, its use in the transport sector can help decarbonize chemical manufacturing and facilitate convergence towards virtuous circles. If it becomes a viable alternative fuel, it will be a boon for society.

The Solar Harvesting Project will culminate in the design of a working prototype hydrogen production system. The prototype will demonstrate solar energy harvesting to produce heat, electricity, and hydrogen at affordable costs.

The team will involve interdisciplinary research from Imperial College, including photochemistry, energy engineering, and biology. The project is expected to reduce fossil fuel consumption by as much as 7%. Once developed and proven, green hydrogen would make hydrogen a viable source of energy for homes and industries.

Green Hydrogen Storage

Mitsubishi Power has announced it has been selected to integrate green hydrogen energy storage into three projects, totaling $3 billion. The three projects will use standard packages to store hydrogen.

Once the green hydrogen technology becomes more widespread, it will be easy to mix it with electrical power. The next step is developing the infrastructure to support the new power generation infrastructure.

This article will cover the technology and its implications for green hydrogen energy storage. Here is a breakdown of some key features.

According to Wood MacKenzie, the global green hydrogen project pipeline has swelled from 3.5 gigawatts to 15 gigawatts in less than ten months. In Germany, analyst Ben Gallagher predicts that green hydrogen production costs will surpass fossil-based hydrogen by 2030.

In a virtual fireside chat on July 12, Pillsbury Law Partner Mona Dajani and Mitsubishi Power America CEO Paul Browning will discuss their latest developments in green hydrogen energy storage.

Although green hydrogen is relatively new, it can be an important pillar in the transition to net-zero emissions economies. While it has faced challenges in the past, recent clean energy successes demonstrate its power to enable change.

By decarbonizing sectors and industries, hydrogen can enhance air quality and increase energy security. Furthermore, as global CO2 emissions reached an all-time high in 2018, outdoor air pollution remains a pressing issue and continues to kill thousands each year.

Beyond the technological breakthroughs that make green hydrogen the next big thing in green energy, hydrogen production and storage is an important first step to meeting energy savings targets. When combined with flexible green hydrogen energy storage, locally created energy is transformative. It also allows for seasonal balancing.

With green hydrogen energy storage, it is possible to store a greater amount of energy for longer periods, which reduces the need for additional power sources. This technology is available in many places around the world, including the U.S.


The cost of green hydrogen is still higher than fossil fuels, but the cost of production is becoming more competitive. The cost of producing green hydrogen is currently in the range of EUR 2.5 to EUR5/kg.

It may reach EUR8/kg in the future, as scale-up is likely to bring it to parity with fossil fuels by 2050. The average unit size of new electrolyzers has increased by tenfold from 2000-09 to 2015-19, which indicates a shift towards commercial-scale applications.

The cost of gray hydrogen is approximately $1.50 per kilogram in the United States, while blue hydrogen is around $2.20. Green hydrogen costs between $3 and $7 per kg. The costs of green hydrogen are projected to fall by 35-65 percent over the next decade, based on the latest estimates by Wood Mackenzie, an industry research firm.

zIn the meantime, the cost of natural gas is expensive in Europe and is only available during baseload operations, so the transition to green hydrogen should come at a relatively low cost.

The cost of green hydrogen is one of the biggest hurdles in unlocking its benefits. However, as the market for green hydrogen continues to grow, governments and businesses should consider policies and incentives that encourage more companies to convert to cleaner hydrogen production.

A targeted approach to this problem is likely to result in lower costs, if the cost of producing green hydrogen challenges is lower than conventional fossil fuels. With this policy, the cost of producing green hydrogen can be brought down substantially.

The cost of green hydrogen production is determined by two major components: fuel and electricity. Fuel accounts for forty to seventy percent of the total production costs. A low-cost electricity source, high efficiency, and low capital expenditure can drive down the cost of green hydrogen production.

With these factors, a competitive cost structure for green hydrogen production is possible. In ten years, green hydrogen will be cheaper than fossil fuels, and India can become the first country to reach $1/kg.


The emergence of renewable sources of green hydrogen energy has raised hopes for decarbonizing industries. Many countries, including the United States, are grappling with high natural gas prices, and mixing green hydrogen with natural gas is one way to reduce carbon emissions. However, this approach has its limits.

Not all natural gas pipeline systems are designed to handle 20 percent hydrogen, and the process will only be profitable in countries with high natural gas prices. Until then, it is necessary to wait for the technology to improve to find a viable alternative.

Hydrogen can be used in a variety of industrial applications. It can be used in vehicles, airships, and spaceships. The decarbonisation of the world economy will give hydrogen more prominence.

The World Hydrogen Council predicts a fifty percent reduction in production costs by 2030. Ultimately, hydrogen is the fuel of the future. Despite its low cost, hydrogen is renewable, easy to store, and can be used for a variety of purposes after it is produced.

Achieving these goals requires a strong infrastructure and an understanding of the long-term benefits of hydrogen. National and regional governments can set long-term goals and guide the development of hydrogen technology.

Similarly, companies need to have clear goals for the future. In the long run, hydrogen can power renewable energy systems and replace natural gas networks for domestic use. There is still a long way to go, but hydrogen is likely to be an integral part of the world's sustainable energy mix in the coming decades.

Green hydrogen is fully renewable, and can be produced from water through electrolysis. This process utilizes electricity and water to split the substance into hydrogen and oxygen. As a byproduct, hydrogen is also released into the atmosphere.

For this process to be climate neutral, it is crucial to use renewable energy. Aside from using renewable energy, hydrogen can be produced through the electrolysis of natural gas. When hydrogen is produced, it is accompanied by a significant reduction in methane emissions.
