"The two most common elements in the universe are hydrogen and stupidity."-Harlan Ellison
As the world faces the pressing challenge of combating climate change and transitioning to a sustainable future, hydrogen has emerged as a promising solution.
With its potential to serve as a clean, efficient, and versatile fuel, countries around the globe are exploring the possibilities of hydrogen-based technologies to drive their economies towards net-zero emissions.
In this three-part series based on the Hydrogen Revolution, I will discuss various aspects of hydrogen as a fuel and its role in our future.
The first part of the blog, titled: 'The Hydrogen Revolution: Fuelling the Path to a Net Zero Future' talks about the two main points:
The Role of Hydrogen in Achieving a Net Zero Scenario: This section explores the role hydrogen can play in transport, power generation, chemical industries, and the building and infrastructure sectors.
The Rise of Hydrogen: A Global Perspective: This section talks about the recent initiatives led by five countries: India, China, Japan, Australia, and Germany.
The Role of Hydrogen in Achieving a Net Zero Scenario
Hydrogen is the most abundant element in the universe, and it can act as a green energy career when produced using clean methods. As countries work towards achieving net-zero emissions, hydrogen is increasingly recognised as a vital component in the decarbonisation puzzle.
Hydrogen is a versatile energy carrier. It can be generated from various energy resources like natural gas, coal, oil, nuclear energy, renewables, etc., throdifferentious technologies like reforming, gasification, pyrolysis, water splitting, etc.
I discuss how hydrogen can transform various sectors to enable a Net Zero future in four major sectors- transport, power, industries, and building.
a. Decarbonizing Transportation
The transport sector, particularly heavy-duty vehicles and long-haul ships, guzzles tonnes of oil and emits millions of gigatonnes of carbon dioxide. The low-carbon hydrogen has the potential to decarbonise this sector.
Hydrogen can be converted to synthetic liquid fuels that can be used as a potential transport sector. Hydrogen as a transport section is presently in various stages of experimentation in light-duty vehicle and heavy-duty vehicle applications.
Hydrogen is transforming not only the in-land road transport sector but also the maritime sector via ammonia, two small railways in Germany and aviation with synthetic aviation fuel.
b. Power Generation & Electricity Storage
Although hydrogen plays a negligible role in power generation today, it is expected to play a crucial role in power generation in the near future. Co-firing ammonia could reduce the carbon intensity of conventional coal power plants.
In the form of compressed gas, ammonia or synthetic methane, hydrogen can also become a long-term storage option to balance seasonal variations in electricity generation from renewable. Power plants equipped with hydrogen fuel cells can provide reliable and flexible electricity, ensuring stability in the grid while reducing carbon emissions.
c. Greening Industrial Processes
Industries account for a substantial share of global emissions, making their decarbonisation critical to achieving a Net Zero future. Hydrogen can be employed as a feedstock and energy source in various industrial processes, such as steelmaking and chemical production, replacing carbon-intensive methods.
By transitioning to green hydrogen, industries can significantly reduce their carbon footprint and contribute to global climate goals.
d. Hydrogen in Heating and Buildings
Building heating and cooling are responsible for significant energy consumption and emissions. Hydrogen offers a clean alternative to fossil fuels for heating applications, and hydrogen-based boilers and furnaces can provide emissions-free warmth to homes and commercial buildings.
Integrating hydrogen technologies into the building sector can contribute to decarbonising this vital part of the energy equation.
The Rise of Hydrogen: A Global Perspective
Hydrogen started gaining too much attention, a critical key element in achieving a carbon-free future in recent years,s, particularly after the Hydrogen Energy Ministerial in 2018 and when G20 leaders in 2019 emphasised hydrogen's role in enabling clean energy transition. It is the most abundant element in the universe, and it can act as a green energy career when produced using clean methods.
To gain insights into the global hydrogen landscape, let's examine some notable government plans and initiatives from different countries.
a. India's National Hydrogen Mission
With its ambitious commitment to the Paris Agreement, India recognises hydrogen as crucial in achieving its climate goals. The National Hydrogen Mission, as part of India's larger energy strategy, aims to scale up hydrogen production and utilisation.
The mission primarily focuses on generating green hydrogen using renewable energy sources like solar and wind power. By promoting research, development, and widespread adoption of hydrogen technologies, India seeks to foster an eco-friendly hydrogen ecosystem.
b. China's Hydrogen Economy Push
Being the world's largest emitter of greenhouse gases, China understands the urgency of transitioning to low-carbon energy sources. In its quest to build a hydrogen economy, China has allocated substantial investments to research, development, and infrastructure for hydrogen production and utilisation.
The country envisions a hydrogen economy primarily powered by clean hydrogen derived from renewable energy and is actively promoting partnerships with international players to advance its hydrogen capabilities.
c. Japan's Green Growth Strategy
Japan, a pioneer in hydrogen research, views hydrogen as a pillar of its green growth strategy. The country aims to realise a carbon-neutral society by 2050, and hydrogen plays a pivotal role in this endeavour.
Japan plans to establish hydrogen supply chains, accelerate research on hydrogen technologies, and encourage global collaboration in the hydrogen sector. Moreover, the Tokyo Olympics showcased Japan's commitment to hydrogen fuel cell technology in public transportation and infrastructure.
d. Australia's National Hydrogen Strategy
With its vast renewable energy resources, Australia has developed a comprehensive National Hydrogen Strategy to leverage its potential in the global hydrogen market. The strategy focuses on exporting hydrogen to high-demand countries and aims to establish Australia's significant major hydrogen supplier. Emphasising the importance of partnerships, Australia seeks to collaborate with international stakeholders to drive the hydrogen transition.
e. Germany's Hydrogen Roadmap
Germany, known for its strong stance on climate action, has outlined a Hydrogen Roadmap that aligns with its ambitious climate targets. The roadmap emphasises the use of hydrogen in industry, transport, and heating, focusing on producing green hydrogen through renewable energies. Germany aims to become a leading exporter of hydrogen technologies and foster cross-border cooperation to promote the development of a global hydrogen economy.
Hydrogen holds immense promise as a clean, efficient, and versatile fuel capable of steering the world towards a Net Zero future.
The blog's contents analyse the critical role that hydrogen can play in transforming the transport, power, chemical industries and building sector. It also highlights a few initiatives significant players like India, China, Japan, Australia, and Germany took to incorporate hydrogen into their policy-making strategy.
The upcoming blog will focus on the other aspects of hydrogen as a future fuel and its role in the Net Zero.
