The Potential of Hydrogen Energy and its Role in Decarbonizing Industries
Introduction
As the world seeks sustainable energy solutions to combat climate change, hydrogen has emerged as a promising candidate. With its abundant supply and potential to produce clean energy, hydrogen has garnered attention across various sectors. In this article, we will explore the role of hydrogen energy in decarbonizing industries, focusing particularly on the shipping and aviation sectors. We will delve deeper into the challenges and opportunities associated with hydrogen as an alternative fuel, and discuss the importance of implementing effective regulations to drive its adoption.
The Hydrogen Industry: Challenges and Advantages
The production and utilization of hydrogen face several challenges. The process of producing green hydrogen, which involves splitting water molecules with clean electricity, is energy-intensive and inefficient. Moreover, hydrogen storage and transportation pose significant obstacles, leading to higher costs and limited accessibility. However, despite these challenges, hydrogen has unique advantages that make it a viable option for decarbonization:
- Abundance: Hydrogen is the most abundant element in the universe, offering a virtually limitless supply.
- Clean Energy Generation: When used in fuel cells or combustion engines, hydrogen produces only water vapor as a byproduct, making it a clean source of energy.
- Versatility: Hydrogen can be utilized in various sectors, including transportation, heating, and power generation.
The Role of Hydrogen in Decarbonizing Shipping and Aviation
The shipping and aviation sectors, which historically rely on fossil fuels, face unique challenges in decarbonizing their operations. While short-term measures such as increasing efficiency and using renewable energy sources can help reduce emissions, the long-term solution lies in finding alternative fuels to replace oil. Hydrogen, with its clean energy generation and versatility, holds immense potential in transforming these industries.
However, the adoption of hydrogen in these sectors is not without its hurdles. The energy-intensive nature of hydrogen production and the losses incurred during conversion into other fuels, such as methanol for shipping or synthetic kerosene for aviation, raise concerns about its cost-effectiveness and overall feasibility. Furthermore, the storage and transportation of hydrogen require significant energy consumption, further impacting its viability.
Despite these challenges, the proponents of hydrogen argue that it can diversify the energy mix in aviation and shipping, offering a more sustainable alternative to conventional fuels. Green hydrogen can be produced using renewable energy sources, ensuring a low-carbon footprint. Moreover, the development of hydrogen infrastructure and efficient storage solutions can mitigate the drawbacks associated with its transportation, eventually reducing costs and increasing accessibility.
Alternative Solutions: Heat Pumps and Electric Cars
While hydrogen is seen as a potential solution for decarbonizing various sectors of the economy, including heating homes and refueling cars, there are alternative options that may offer greater efficiency. Heat pumps and electric cars, which directly utilize electricity, have gained significant traction and present compelling alternatives to hydrogen. These technologies eliminate the need for energy-intensive hydrogen production and transportation, making direct electricity utilization a more practical choice.
This raises a critical question about the distribution of resources and efforts. Instead of focusing primarily on developing a hydrogen supply for sectors that don’t necessarily require it, such as heating and transportation, governments and industries should prioritize allocating resources towards sectors like aviation and shipping, where hydrogen offers distinct advantages and the need for decarbonization is urgent.
The Need for Regulation and Investment
To accelerate the transition to a post-oil world and promote the adoption of hydrogen energy, strong regulations and increased investment are paramount. The aviation and shipping industries must send clear signals to green hydrogen producers, establishing a robust demand for hydrogen-based fuels and driving innovation. Effective regulation can ensure that resources are channeled efficiently and that green hydrogen production is supported, fostering a sustainable future.
Moreover, governments need to provide a conducive environment for the development of hydrogen infrastructure and storage systems. By incentivizing investments in green hydrogen and integrating the necessary regulations, policymakers can facilitate the widespread availability and affordability of hydrogen, making it an attractive choice for industries seeking to decarbonize.
Overcoming Challenges: Sustainable Aviation Fuels and Limited Supply
In the aviation industry, Sustainable Aviation Fuels (SAFs) have gained prominence as a possible solution to reduce emissions. However, despite their name, SAFs often include non-sustainable components and may not fully align with the goal of decarbonization. The use of unreliable biofuels and limited supplies of sustainable raw materials pose challenges in achieving truly sustainable aviation fuels.
Similarly, the shipping industry faces constraints in securing a sufficient supply of green methanol, a potential sustainable fuel. Companies like Maersk, one of the largest shipping companies globally, have committed to transitioning to sustainable fuels but express concerns about the availability of green methanol for their vessels.
The existing legislation, such as the EU’s decarbonization measures for aviation and shipping, emphasizes low-carbon fuels without specifically emphasizing sustainable low-carbon fuels like green hydrogen. This highlights the need for comprehensive regulations that prioritize sustainable alternatives and enable the necessary infrastructure and supply chains to be developed.
Creating Demand and Encouraging Investment
The lack of policies supporting green hydrogen production for shipping and aviation has resulted in a gap between planned hydrogen projects and the actual implementations. The absence of strong demand and clear signals from key industries impedes the progress of green hydrogen adoption. Therefore, to bridge this gap and encourage investment, regulatory frameworks must stimulate innovation and provide the necessary impetus for the hydrogen industry to thrive in these sectors.
Conclusion: Filling the Hydrogen Gap for a Greener Future
Hydrogen energy holds significant promise in decarbonizing industries such as shipping and aviation. While challenges related to production, storage, and transportation persist, the advantages of hydrogen, including its abundance, clean energy generation, and versatility, make it a compelling alternative to fossil fuels. To realize its potential, effective regulations that prioritize sustainable low-carbon fuels, like green hydrogen, are essential. Additionally, increased investment, infrastructure development, and collaboration between governments and industries will drive the adoption of hydrogen and pave the way for a greener and more efficient future.
Summary
In summary, hydrogen energy offers a promising pathway to decarbonize industries such as shipping and aviation. While there are challenges related to production efficiency, storage, and transportation, hydrogen’s advantages in terms of abundance, clean energy generation, and versatility make it an attractive alternative. However, the adoption of hydrogen requires strong regulations and investments to drive innovation and ensure a sustainable supply. Governments and industries should focus on sectors where hydrogen offers distinct advantages and prioritize resource allocation accordingly. By doing so, the world can transition to a post-oil future and achieve a greener and more efficient energy landscape.

Shipping and aviation are just starting to decarbonise and, unlike other industries, don’t have many easy options for doing so.
There are ways to reduce emissions in these two sectors in the short term: increase efficiency, use wind power on ships and fly less. We have to do all of this. Eventually, though, these industries will need new fuels to replace oil – and those fuels will likely be made from hydrogen.
But hydrogen is not easy. The green version of the fuel is produced via the energy-intensive process of splitting water molecules with clean electricity – and if you convert it into another fuel (such as methanol for shipping or synthetic kerosene for aviation) , further energy is lost. Furthermore, hydrogen is difficult to store and cannot be transported without serious energy consumption. You can imagine how much it will cost.
The hydrogen industry touts the fuel as a solution for nearly every sector of the economy that needs to be decarbonised: it is cited as an option for heating homes and refueling our cars. But there are better alternatives. As long as heat pumps and electric cars exist, it will not make much sense to turn electricity into hydrogen instead of using it directly.
Building a supply of hydrogen for use in sectors that don’t need it, instead of focusing on those that do, will delay the transition to a post-oil world by decades. We need regulation to ensure that the aviation and shipping industries can switch to hydrogen instead. And with recently increased investor confidence in fuel, governments must ensure it is not wasted.
At present, the aviation industry has successfully created a new acronym: SAF, or Sustainable Aviation Fuels. But, despite what the name suggests, SAFs also include non-sustainable components. Yet when I talk to insiders, they cite these hybrid fuels as the reason they are unwilling to push governments into policies that accelerate the deployment of hydrogen.
SAFs cover everything from carbon-intensive biofuels to synthetic kerosene made from green hydrogen. Biofuels, when grown from crops, often emit more carbon than the fuels they replace when considering indirect land use change (the change that occurs when a field previously used for crops is devoted to the production of biofuel feedstock ). While they can also be made from truly sustainable raw materials such as used cooking oil, the supply of such inputs is very limited.
Meanwhile, in the shipping world, Maersk, the world’s second-largest shipping company, has pledged to switch to sustainable fuels. However, its chief executive said he also doesn’t think there will be enough green methanol available for the company’s recently ordered vessels.
The EU has introduced new legislation to decarbonise aviation and shipping. But the legislation encourages a switch to low-carbon fuels (such as unreliable biofuels), rather than sustainable low-carbon fuel (green hydrogen). Meanwhile, politicians are sending the limited supply of hydrogen we have to sectors that don’t need it: in the UK, for example, there are plans to trial hydrogen heating and other alternative heating solutions by 2025.
There is a regrettable lack of policies to support green hydrogen production for shipping and aviation. This, in turn, is slowing demand and discouraging investment. There is a gap between the number of hydrogen projects planned and those that will be implemented, due to lack of demand.
Regulation stimulates innovation and would ensure that demand. If they are to get the hydrogen they need, airlines and shipping companies need to send clear signals to green hydrogen producers as soon as possible.
But without legislation, both industries will have to shoulder these costs voluntarily and, as we have seen, Maersk also feels unable to do so. It’s time to fill the hydrogen gap, for the sake of a greener and more efficient future.
