Abstract

The pressure to move to sustainable energy sources is obvious in today's fast changing energy environment. In this context, green hydrogen appears as a beacon of hope, with the potential to reinvent the paradigms of energy consumption, particularly in the transportation and aviation sectors. Hydrogen has long been intriguing owing to its unique characteristics. It is not only an energy transporter; it has the power to alter the game. Its growing significance is due to its capacity to decarbonize energy generation. Traditional hydrogen generation techniques have contributed considerably to world CO2 emissions, accounting for over 2 % of total emissions. This environmental problem is successfully addressed by the development of green hydrogen, which is created from renewable energy sources. The International Energy Agency (IEA) predicts a 25 to 30 % increase in global energy consumption by 2040, which is a very grim scenario. If continue to rely on coal and oil, this growing demand will result in greater CO2 emissions, exacerbating climate change's consequences. In this situation, green hydrogen is not only an option but a need. Because green hydrogen has properties with conventional fuels, it can be simply integrated into current infrastructure. This harmonic integration ensures that the shift to hydrogen-based solutions in these sectors would not demand a complete redesign of the present systems, assuring cost-effectiveness and practicality. However, like with any energy source, green hydrogen has obstacles. Its combustibility and probable explosiveness have been cited as causes for concern. However, developments in safety measures have successfully mitigated these dangers, ensuring that hydrogen may be used safely and efficiently across various applications. A further difficulty is its energy density, particularly in comparison to conventional fuels. While its energy-to-weight ratio may be good, its bulk poses challenges, particularly in the aviation industry where space is at a premium. Beyond its direct use as a fuel, green hydrogen has potential in auxiliary capacities. It may be used as a dependable backup energy source during power outages, as well as in a variety of different sectors and uses, ranging from manufacturing to residential. Green hydrogen's adaptability demonstrates its potential to infiltrate all sectors of our economy. Storage is an important enabler for broad hydrogen use. Effective hydrogen storage technologies guarantee not only its availability, but also its viability as a source of energy. Current research and advancements in this field are encouraging, which strengthens the argument for green hydrogen. At conclusion, green hydrogen is in the vanguard of sustainable energy solutions, particularly for the transportation and aviation industries. In our collaborative quest of a sustainable future, its unique features and environmental advantages make it a vital asset. As we explore further into the complexities of green hydrogen in this publication, we want to shed light on its potential, obstacles, and future route.
