Green hydrogen is often touted as a key solution for a clean energy future, but its global rollout faces significant hurdles. Despite strong interest and some regional progress, widespread adoption remains elusive. Curious about what's holding back green hydrogen? Below, we explore the main challenges, costs, infrastructure issues, and how different countries are approaching this promising but complex energy source.
-
Why is green hydrogen so expensive to produce?
Green hydrogen is made using renewable energy to split water into hydrogen and oxygen. This process, called electrolysis, requires a lot of electricity, which can be costly. High equipment costs, the need for abundant renewable energy sources, and the current scale of production all contribute to its high price, making it less competitive compared to fossil fuels.
-
What infrastructure challenges are slowing down green hydrogen projects?
Building the infrastructure for green hydrogen—like pipelines, storage facilities, and fueling stations—is complex and expensive. Many regions lack the necessary pipelines or storage options, and developing these systems takes time and significant investment. Without widespread infrastructure, scaling green hydrogen remains difficult.
-
How are different countries approaching the transition to clean energy?
Countries are taking varied approaches. For example, Hong Kong's Towngas is building hydrogen-powered EV charging stations to lower costs as they scale up. Meanwhile, some nations like Australia are canceling or delaying projects due to policy shifts and economic hurdles. These differences reflect each country's priorities, resources, and policy environments.
-
What role will hydrogen play in future energy systems?
Hydrogen is expected to be a key part of future energy systems, especially for sectors hard to electrify, like heavy industry and aviation. It can serve as a clean fuel, energy storage medium, and a way to balance renewable energy supply. However, its success depends on overcoming current economic and infrastructure challenges.
-
Are there any regions making significant progress with green hydrogen?
Yes, some regions like parts of Asia are making strides, with companies investing in pilot projects and infrastructure. For example, Hong Kong is moving forward with hydrogen EV stations. Still, overall progress is uneven, with many projects facing setbacks due to costs and policy uncertainties.
-
Why are some big companies withdrawing from green hydrogen projects?
Many large companies, including BP and Fortescue, are pulling back from green hydrogen initiatives because of high costs, policy uncertainties, and logistical challenges. These setbacks highlight how difficult it is to make green hydrogen commercially viable on a large scale at present.
