The article discusses the importance of government intervention in jump-starting the green hydrogen economy to tackle issues like climate change. It highlights the efforts of innovators like Zhenyu Zhang working on producing green ammonia by extracting hydrogen from water with carbon-free electricity. Green hydrogen and ammonia have significant potential as alternative fuels across various sectors. The economic challenge of adopting hydrogen for fuel is addressed, emphasizing the need for existing infrastructure to support its usage. Governments worldwide, such as Germany, the U.S., and Saudi Arabia, are making substantial investments to develop hydrogen technology and infrastructure through public-private partnerships and tax credits. The U.S. Bipartisan Infrastructure Law and initiatives like the Neom Green Hydrogen Company in Saudi Arabia are key examples of such governmental support. These interventions are seen as essential to shape markets and drive the transition towards a sustainable hydrogen economy. The article also mentions the ongoing debate over government subsidies for hydrogen production, with differing views on supporting carbon-intensive hydrogen temporarily for industry development. Overall, the article emphasizes the crucial role of government policies in promoting the growth of the hydrogen market and transitioning towards a sustainable future.
