Nuevo León, a key industrial region in Mexico, has embarked on an international initiative to advance the low-carbon hydrogen sector. Joining the Hydrogen for Development (H4D) program led by the World Bank, Nuevo León aims to cultivate a sustainable hydrogen economy in developing nations. The state's Renewable Energy Agency highlights the necessity for significant investments in renewable energy infrastructure to expand the current 1,000 MW of renewable capacity. By participating in the h2 Regional Energy Hub with Houston, Nuevo León seeks to bolster local supply chains and integrate hydrogen into diverse industrial domains. However, challenges persist, including financial, regulatory, and technological hurdles in Latin America, necessitating innovations like enhanced electrolyzer efficiency to attract investors. The International Energy Agency's Global Hydrogen Review 2024 underscores the need for a 140% rise in renewable energy capacity by 2030 in Latin America to achieve a potential 7 million tons of low-carbon hydrogen annually. Simultaneously, the surge in Mexico's hydrogen economy is elevating demand for International Renewable Energy Certificates (I-REC) for green energy projects. Despite the limited growth in I-REC supply, rising certificate prices pose a medium-term challenge to green hydrogen project competitiveness if demand continues to outpace infrastructure expansion.
