The global push towards green hydrogen as a key element in achieving decarbonization goals is facing challenges and opportunities. While clean hydrogen is recognized as crucial for sectors like steel and aviation, the road to its widespread adoption is proving difficult. Investments are substantial, with the EU committing 300 billion euros, yet delivery delays and cost inflation hinder progress. To bridge the gap, blue hydrogen with carbon capture and storage is seen as a viable transition solution. Despite the growth in low-carbon hydrogen projects, they are insufficient to meet escalating demand and ambitious policy targets. Governments are revising their green hydrogen forecasts, signaling the need for action. Policies such as the EU's ReFuelEU regulation and instruments like the US 45Q tax credit are driving investments in low-carbon projects. However, regulatory uncertainties remain, posing obstacles to scaling up hydrogen production. The industry hub model emerges as a potential solution to optimize hydrogen supply chains, reduce costs, and mitigate risks for industrial sectors. Addressing challenges like storage, transportation, and regulatory frameworks will be crucial in realizing the potential of green hydrogen and its pivotal role in global decarbonization efforts.
