This globally dispersed interest highlights the potential for hydrogen to bridge the gap between advanced and developing economies, offering a unified solution to a universal challenge.

Hydrogen as a clean energy source

Current advancements in hydrogen technology, particularly in electrolysis – the process of splitting water into hydrogen and oxygen using electricity – have significantly reduced the cost and increased the efficiency of hydrogen production. This progress is critical in making hydrogen a viable alternative to traditional fossil fuels.

However, challenges remain in the widespread adoption of hydrogen as a primary energy source. The main hurdle is the current dependence on fossil fuels for hydrogen production, which involves significant carbon emissions. Transitioning to Green Hydrogen, produced using renewable energy, is essential but requires substantial investment in renewable energy infrastructure and technological innovation.

Infrastructure and market development

For hydrogen to be a mainstay in the energy landscape, developing a robust infrastructure is crucial. This involves the creation of efficient hydrogen production facilities, reliable storage systems, and extensive transportation networks. The development of such infrastructure is a significant undertaking that requires considerable investment and coordination among governments, industry players, and other stakeholders.

Market development also plays a pivotal role in the hydrogen economy. Establishing a market for hydrogen, particularly in sectors hard to electrify like heavy industry and transportation, is essential for its growth. Policymakers and industry leaders need to work together to create favorable regulatory frameworks and incentives that encourage the use of hydrogen. Additionally, fostering public-private partnerships can accelerate the development and commercialization of hydrogen technologies.

However, the cost associated with building this infrastructure and market remains a challenge. High initial investments and the current expensive nature of hydrogen production compared to traditional energy sources are barriers that need to be addressed through innovation, economies of scale, and policy support.

Addressing sustainability in hydrogen production

Environmental sustainability in hydrogen production is a critical aspect of its role in a low-carbon economy. While hydrogen is potentially a clean energy carrier, its production method greatly influences its environmental impact. Currently, the majority of hydrogen production is ‘grey hydrogen’, derived from natural gas, releasing significant amounts of carbon dioxide. Transitioning to ‘Green Hydrogen’, produced via renewable-powered electrolysis, is crucial to realize the environmental benefits of hydrogen.

The development of carbon capture and storage (CCS) technologies offers a pathway to reduce emissions from grey hydrogen production. While this ‘blue hydrogen’ is a step in the right direction, it is not a completely carbon-neutral solution. Thus, the focus must be on accelerating the transition to Green Hydrogen production.

Moreover, the environmental impact of the entire hydrogen production and supply chain, including water usage, must be considered. Ensuring that hydrogen contributes positively to environmental sustainability necessitates continuous research and development in efficient and eco-friendly production technologies.

The global vision for hydrogen

Presently, hydrogen predominantly serves as an industrial gas, manufactured primarily from fossil fuels through carbon-intensive processes. This sector, accounting for about 2% of global energy consumption, is poised for a dramatic transformation. The ambition is to reinvent hydrogen production into a cleaner, low-carbon process, potentially revolutionizing its role from a mere industrial byproduct to a versatile, low-carbon energy carrier. This vision aligns with global business interests and political ambitions, signaling a unified move towards adopting hydrogen and its derivatives as key players in the low-carbon energy narrative.

The Middle East: Renowned for its vast oil reserves, the Middle East is uniquely positioned to become a global hydrogen powerhouse. The region’s abundant solar and wind resources are ideal for Green Hydrogen production through electrolysis. Countries like Saudi Arabia and the United Arab Emirates are investing heavily in hydrogen infrastructure, aiming to become major exporters of clean hydrogen. However, the challenge lies in developing cost-effective production and export mechanisms to turn this vision into reality.

India: As one of the world’s fastest-growing economies, India’s energy demands are skyrocketing. The country’s commitment to a sustainable energy future is evident in its ambitious renewable energy targets. Hydrogen, particularly Green Hydrogen, is gaining attention as a viable option to meet India’s diverse energy needs while reducing its carbon footprint. The challenge for India lies in integrating hydrogen into its existing energy infrastructure and scaling up production affordably.

Europe: In Europe, several countries are actively developing hydrogen infrastructures. The Netherlands plans a €1.5 billion hydrogen network by 2030, partially funded by the state. Germany’s National Hydrogen Strategy aims for an 11,200 km backbone by 2032, with significant roles for private and regional companies. Spain and the UK have conditional plans for hydrogen infrastructure development by 2026. Moreover, local gas grids might invest in connecting hydrogen producers to industrial users, though such projects are currently limited.

A key challenge in Europe is the absence of short-term regulatory frameworks for renewable gas infrastructures, leading operators to seek private or state funding. Substantial investments in low-carbon hydrogen networks aren’t expected before 2030, but the sector must be financially prepared for potential heavy investments.

Funding strategies and balance sheet strength are crucial for maintaining credit quality amid uncertain natural gas demand and unclear prospects for green gases. Regulatory support, affecting cost recovery and tariff changes, remains vital for the creditworthiness of these companies, with increased uncertainties as regulatory periods conclude and new gas usages emerge.

To ensure the success of this varied approach, it’s essential to address three significant obstacles: firstly, reducing expenses and clearing any production or supply hindrances; secondly, achieving uniformity in how low-carbon hydrogen is defined and categorized; and thirdly, securing strong and dependable pledges from customers to purchase it.

The latter part of the 2020s will reveal whether these challenges can be met and, if so, the methods by which they will be tackled.

Reducing costs and overcoming bottlenecks

The journey towards mainstreaming clean hydrogen is heavily contingent on cost-efficiency across the entire supply chain. This encompasses production costs (including methods like methane reforming and electrolysis), infrastructure expenses, and storage and transportation complexities.

The goal is to find the most economically viable methods to reduce these costs while ensuring the hydrogen is delivered at the required purity and pressure for diverse applications. The need for cost-effective storage solutions further adds to the complexity, necessitating innovative approaches to streamline and economize the hydrogen supply chain.

Classification, definition, and harmonization

Establishing clear, universally accepted classifications and definitions is imperative for hydrogen technology to gain a foothold in the global market. This includes achieving harmonization in green credentials, which is vital for accessing financing and commercialization opportunities. A significant aspect of this challenge is the concept of “additionality” in electrolysis, ensuring that dedicating renewable energy sources to hydrogen production does not inadvertently increase carbon emissions elsewhere.

The quest for common international standards and agreements on these definitions is ongoing, with entities like the International Partnership for Hydrogen and Fuel Cells in the Economy playing a pivotal role.

Securing customer commitment

The viability of low-carbon hydrogen in the energy sector hinges significantly on customer demand. This demand is influenced by factors like cost reduction and regulatory harmonization.
