Green hydrogen is gaining global recognition as a clean energy solution to decarbonize sectors like transportation and industrial manufacturing. The International Solar Alliance, led by India, launched the Green Hydrogen Innovation Centre, and India itself approved $2.3 billion for green hydrogen production, use, and export. The G-20 summit in New Delhi is expected to address global cooperation on green hydrogen manufacturing and supply.
When green hydrogen is produced using renewable energy, it earns its “green” credentials. Analysts project the global green hydrogen market to exceed $410 billion by 2030, more than doubling its current size.
Green hydrogen finds applications in various industries, including steelmaking, concrete production, chemical manufacturing, and fertilizer production. It can also generate electricity, fuel transportation, and provide heating for homes and offices. Green hydrogen has the potential to reduce emissions in sectors like fertilizer production, crucial for global food production.
While green hydrogen offers promise in the transition to clean energy, challenges exist. Its volatility and the need for special transport pipelines limit its use in some applications. Green hydrogen production can be less efficient than direct electrification, leading to energy loss. Cost, investment risks, water requirements, and a lack of international standards have also been raised as concerns.
Some critics argue that green hydrogen’s potential is overstated due to lobbying by the oil and gas industry. However, organizations like the International Renewable Energy Agency project significant growth in hydrogen demand, especially for replacing gray hydrogen produced from fossil fuels.
Replacing existing gray hydrogen demand is seen as a crucial first step, paving the way for green hydrogen’s expanded use in industries, shipping, and aviation, according to experts.
