Green hydrogen, once heralded as a cornerstone of the global transition to clean energy, is encountering significant economic challenges due to its high production costs. This reality is prompting a reevaluation of its role in future energy strategies.

A study from Harvard University, published in the journal *Joule*, reveals that the comprehensive costs associated with green hydrogen—including production, storage, and distribution—render it a prohibitively expensive method for reducing carbon emissions. The research indicates that the expense per ton of carbon dioxide mitigated via green hydrogen ranges from $500 to $1,250, whereas current carbon capture and storage technologies cost between $100 and $1,000 per ton.

Green hydrogen is produced by using renewable electricity to split water molecules into hydrogen and oxygen through electrolysis. Despite advancements in this technology, the associated costs remain substantially higher compared to traditional hydrogen production methods that utilize fossil fuels. The International Energy Agency (IEA) notes that while green hydrogen holds potential, it faces considerable obstacles, including unclear demand signals and regulatory uncertainties.

The economic viability of green hydrogen is further complicated by the need for substantial infrastructure investments. Establishing the necessary production facilities, storage solutions, and distribution networks requires significant capital, contributing to the overall expense. Additionally, the efficiency of electrolysis and the intermittent nature of renewable energy sources add layers of complexity to cost reduction efforts.

In the United States, the landscape for hydrogen energy is influenced by policy decisions. The Inflation Reduction Act, introduced during President Joe Biden's administration, provided support for renewable energy initiatives, including green hydrogen. However, with the election of President Donald Trump, who has expressed skepticism about climate change, there is potential for policy reversals that could impact the industry's growth. Companies like Thyssenkrupp Nucera, a producer of electrolysers for low-carbon hydrogen, have indicated readiness to relocate resources if U.S. policies become unfavorable. CEO Werner Ponikwar emphasized the company's global operations and asset-light business model, which allow for adaptability to changing policy environments.

The high costs associated with green hydrogen have led some energy companies to reassess their investments in this area. For instance, Origin Energy recently abandoned its green hydrogen project in Hunter Valley, citing economic challenges and a lack of market interest. This move reflects a broader trend of skepticism regarding the immediate viability of green hydrogen as a cost-effective energy solution.
