Green Hydrogen: Powering the Future and NTPC’s Pioneering Path
In 2021, the United Nations Climate Change Conference in Glasgow, known as COP26, heralded the beginning of a transformative journey for India. Among the key resolutions, the concept of “Green Hydrogen” emerged as a crucial pillar to help India achieve its ambitious target of net-zero emissions by 2070. This renewable energy source is not only pivotal for meeting India’s energy needs but also for securing a sustainable future for the generations to come. At the forefront of this revolutionary shift is NTPC, India’s largest power utility, driving forward pioneering activities aligned with global standards to foster the growth of the green hydrogen ecosystem.
Green Hydrogen is produced by electrolyzing water using renewable energy sources, ensuring zero carbon emissions in the process. Unlike grey hydrogen, which is derived from fossil fuels and contributes significantly to CO2 emissions, Green hydrogen offers a cleaner, sustainable alternative. The Indian government, recognizing the critical importance of this energy carrier, launched the National Green Hydrogen Mission in early 2023. This mission targets the production of 5 million metric tonnes per annum (MMTPA) of green hydrogen by 2030, positioning India as a global leader in the hydrogen economy.

To support the ambitious green hydrogen targets, India needs to harness its vast renewable energy potential. The country is already making significant strides in solar, onshore wind, offshore wind, biomass, hydro, and pumped storage sectors. The government has introduced multiple Production Linked Incentive (PLI) schemes to encourage capacity addition in these areas. The integration of Battery Energy Storage Systems (BESS) ensures that renewable energy can meet the round-the-clock requirements necessary for green hydrogen production. Pilot projects in sectors like steel, shipping, and mobility are already underway, showcasing the practical applications and benefits of green hydrogen.
Green hydrogen’s value chain begins with renewable energy and extends to various applications across different industries. It plays a crucial role in decarbonizing hard-to-abate sectors such as steel, fertilizers, refineries, cement, and mobility. The National Green Hydrogen Mission is not just about production; it encompasses the entire ecosystem, including transportation, storage, and utilization. The Ministry of New and Renewable Energy (MNRE) is spearheading several initiatives to achieve these goals, ensuring that green hydrogen becomes a cornerstone of India’s energy transition.

Supportive policies and regulations are vital for fostering the development of green hydrogen. The Indian government has introduced various policy instruments, such as feed-in tariffs, carbon pricing mechanisms, and regulatory frameworks, to create a conducive environment for green hydrogen production and utilization. These policies aim to reduce the cost of green hydrogen, making it competitive with other energy sources. Additionally, collaborations with international organizations and countries help India align its green hydrogen initiatives with global standards and best practices.
Financing green hydrogen projects requires innovative approaches due to their capital-intensive nature. Public-private partnerships, green bonds, and other innovative financial instruments are essential to bridge the investment gap. The government and financial institutions are working together to create favorable conditions for investors, ensuring that the green hydrogen sector receives the necessary funding to accelerate its growth. By leveraging these financial tools, India can attract significant domestic and international investments, fostering the development of a robust green hydrogen ecosystem.

NTPC is leading the way with several groundbreaking pilot projects across different sectors and geographies, serving as real-world implementations of green hydrogen and providing valuable insights for future large-scale deployments. For instance, NTPC is pioneering hydrogen mobility by deploying 10 Fuel Cell Electric Vehicles (FCEVs) in intra and intercity applications, with five FCEVs operating in Leh and another five in Delhi. These vehicles will be fueled by green hydrogen from dedicated fueling facilities, demonstrating the viability of hydrogen as a clean transportation fuel. Additionally, in Delhi NCR, NTPC is assessing the feasibility of replacing diesel generator sets with a minimum 500 kW hydrogen-based fuel cell system for backup power, showcasing the potential of hydrogen in providing reliable and clean energy storage solutions.

Moreover, NTPC is exploring the establishment of a green power-based 50 kW microgrid in Andhra Pradesh, using a combination of electrolyzers and fuel cells to create a scalable model that can be expanded to megawatt-scale systems. This highlights the flexibility and efficiency of hydrogen-based energy storage. A pilot project in Western India is also investigating the technical challenges of blending hydrogen with natural gas in City Gas Distribution (CGD) networks. This initiative aims to decarbonize the existing natural gas grid while reducing reliance on imported natural gas, offering a cost-effective pathway to a cleaner energy system.

Furthermore, NTPC is pursuing the production of green methanol to monetize CO2 from waste flue gas at coal-fired thermal power plants, establishing a 10 TPD (Tonnes Per Day) plant at NTPC Ramagundam, Telangana, utilizing power from a 100 MW floating solar project. This project exemplifies the innovative use of green hydrogen in creating valuable products from waste emissions. Additionally, green ammonia, an efficient carrier of hydrogen, is another focus area for NTPC. The company is setting up multiple Ultra Mega Renewable Energy Power Parks (UMREPPs) across India, with part of the power earmarked for green ammonia production. This green ammonia can replace imported or domestically produced grey ammonia, supporting both domestic use and export markets.
One of NTPC’s most significant achievements is the launch of India’s first desalination-based hydrogen plant in Vizag. This project, developed in collaboration with the Indian Institute of Petroleum and Energy (IIPE), utilizes desalinated water from NTPC Simhadri’s existing plant for hydrogen generation through electrolysis. This approach eliminates the reliance on freshwater resources, offering a sustainable solution in water-scarce regions. The project, with an estimated investment of Rs 35 crore, aims to establish a 1 TPD capacity plant, setting a new benchmark in the renewable energy sector.
The desalination-based hydrogen plant utilizes waste heat from the power plant for desalination, ensuring carbon neutrality. This innovative and environmentally friendly process not only produces green hydrogen but also promotes the production of green ammonia and green methanol, amplifying India’s renewable energy capabilities.

NTPC’s pioneering efforts in green hydrogen mark a monumental step towards a sustainable future, leveraging India’s vast renewable energy potential to address the country’s energy security needs while significantly contributing to global climate goals. The successful implementation of various pilot projects underscores NTPC’s commitment to innovation, collaboration, and environmental stewardship, demonstrating the viability of green hydrogen as a key solution to decarbonize multiple sectors of the economy. NTPC’s initiatives, aligned with the National Green Hydrogen Mission and global standards, set an inspiring example for other nations to follow. With continued support from government policies, innovative financing solutions, and technological advancements, green hydrogen can transform India’s energy landscape, ensuring a cleaner, more sustainable future for generations to come. Congratulations to NTPC for their remarkable achievements in the green hydrogen sector. Your dedication to sustainability and the successful implementation of landmark projects deserve applause. Together, let us embrace renewable energy, advocate for green hydrogen, and support the mission to create a greener and more sustainable world.. 🌍💚
