In the battle against climate change, hydrogen has emerged as a key player in transforming industries. It holds great potential to reduce greenhouse gas emissions and help achieve sustainability goals. This versatile fuel can revolutionize traditional processes and offers a path towards a net-zero economy. In this article, CE Marking Authority will examine how hydrogen is currently used in various industries, its contributions to sustainability, and the numerous opportunities and challenges ahead. We will also look at cutting-edge processing technologies and vital safety best practices that stakeholders should consider.
The Promises of Hydrogen in Industrial Processes
Hydrogen is a clean fuel that produces only water as a byproduct when burned. This purity places hydrogen at the centre of discussions about sustainable energy solutions.
The flexibility of hydrogen allows it to fit into many industrial applications. For example, in the production of ammonia—which serves as a critical component in fertilizers—over 160 million tons are produced annually. A shift to cleaner hydrogen sources could help significantly cut carbon emissions from this essential process. Furthermore, traditional hydrogen production methods, primarily based on natural gas, are being complemented by cleaner approaches like electrolysis, which splits water into hydrogen and oxygen using renewable energy.
Adopting hydrogen not only diminishes carbon emissions but also enhances energy efficiency. For instance, companies that switch to hydrogen-powered processes report energy efficiency improvements of around 20-30% in chemical manufacturing. Moreover, hydrogen's ability to be stored and transported efficiently means businesses can decouple energy production from consumption. This is especially valuable for industries reliant on renewable energy, which might not always align with peak demand.
Market Opportunities in the Hydrogen Economy
The transition to a net-zero economy is creating exciting opportunities in the hydrogen market. According to recent estimates, the global hydrogen market could reach upwards of $2.5 trillion by 2050, fueled by green energy policies and technological advancements.
Hydrogen as a Feedstock:
Hydrogen's role as a feedstock in chemical manufacturing is one of the most significant opportunities. The ammonia industry, which contributes to about 1.8% of global CO2 emissions, is increasingly turning towards cleaner hydrogen sources. For example, the adoption of green hydrogen in this sector could reduce emissions by an estimated 3.4 billion tons, aligning with stricter regulations. The CE Marking Authority has conducted numerous compliance programmes covering decanter disk modules, nutrient transfer equipment, dewatering equipment and thermal reactor assemblies
Energy Sector Integration:
Integrating hydrogen into the energy sector is another promising avenue. Hydrogen can provide energy storage, especially in regions predominantly relying on solar or wind sources. For example, Germany has started incorporating hydrogen into its energy strategy, which has helped stabilize the grid and utilize renewable sources more effectively. The CE Marking Authority has already certified a solar array.
Export Potential:
Countries rich in renewable resources, such as Australia and Saudi Arabia, are developing strategies to become major hydrogen exporters. Australia aims to generate 200 million tons of hydrogen annually by 2050, positioning itself to meet increasing global energy demands while promoting economic growth and international collaboration.
Internal Markets
bp Aberdeen Hydrogen Energy Limited – the joint venture between bp and Aberdeen City Council – has announced that the final investment decision for its Aberdeen Hydrogen Hub project has been agreed, supporting the region’s energy transition ambitions and its drive to become a leader in lower carbon energy.
The planned hub will feature a hydrogen production, storage and distribution facility, located at Hareness Road, Aberdeen, which will be powered by electricity generated at a solar farm to be installed on the former Ness landfill site.
Challenges Facing Hydrogen Adoption
Despite the promising prospects, several hurdles must be overcome to facilitate the broad adoption of hydrogen in industrial processes.
Infrastructure Overhaul:
The current hydrogen infrastructure is limited. Transitioning from natural gas pipelines to hydrogen-compatible systems will require substantial investment. For instance, retrofitting existing pipelines could cost billions and needs collaboration across public and private sectors to ensure successful implementation.
Economic Viability:
Green hydrogen remains more expensive than hydrogen derived from fossil fuels. For instance, producing a kilogram of green hydrogen can cost around $3 to $6, while fossil fuel-derived hydrogen sits closer to $1 to $2. Government policies and incentives must support research and development to make green hydrogen economically competitive.
Safety Concerns:
Hydrogen’s flammability poses safety challenges that must be carefully managed. Involving all stakeholders in rigorous safety assessments allows industries to identify risks and enforce best practices. Training and advanced technologies, like automated leak detection systems, are vital for ensuring safe operations.
Latest Processing Technologies for Hydrogen
As the interest in hydrogen grows, various technologies have emerged to improve its production and use.
Electrolysis Innovations:
Recent innovations in electrolysis, particularly the shift from alkaline to proton exchange membrane (PEM) electrolysis, have increased efficiency. New PEM electrolyzers can operate at 85% efficiency compared to traditional systems, making them a game-changer for hydrogen production from renewable sources.
Steam Methane Reforming with Carbon Capture:
Combining carbon capture and storage (CCS) with steam methane reforming (SMR) allows industries to continue using natural gas while lowering emissions. This hybrid approach captures up to 90% of CO2 emissions, making it a feasible transitional strategy toward greener production methods.
Hydrogen Fuel Cells:
Hydrogen fuel cells generate electricity efficiently and are increasingly used in transportation. For instance, one of our customers in Norway has already launched a hydrogen fuel cell for vehicles. These fuel cells can also support industrial energy needs, paving the way for sustainable energy.
Best Practices for Safety in Hydrogen Usage
As hydrogen's presence grows in industries, ensuring safety is critical. Here are some best practices to implement:
Risk Assessment and Management:
Performing rigorous risk assessments helps identify hazards in hydrogen operations. Comprehensive risk management plans ensure safe operational protocols. Collaborating with experts across multiple sectors can enrich these assessments.
Product Compliance
Ensuring mechanical and electrical equipment and their assemblies meet the regulatory requirements and the technical construction files are in place
Training and Education:
Providing continuous training for employees handling hydrogen is essential. A knowledgeable workforce can prevent accidents and ensure compliance with safety protocols. Cultivating a safety-oriented culture empowers employees to voice concerns and propose improvements.
Technological Solutions:
Implementing advanced safety measures, such as real-time monitoring systems, can enhance operational safety. Investing in technologies like automated shut-off valves (already certified for hydrogen) can provide swift responses to emergencies, reassuring both stakeholders and customers. Hydrogen has one safety advantage over other flammable fuels: hydrogen is lighter than air and rises faster than natural gas, which means that it disperses rapidly when released.
