Hydrogen's Role in a Sustainable Future
Understanding the Magnitude of Climate Change and Clean Energy
Climate change represents one of the most significant challenges facing our planet. It's a "huge" issue, not just in scale but in complexity. The transition to clean energy is pivotal in our efforts to address this global concern. However, it's essential to approach this transition thoughtfully, recognizing the diverse viewpoints and concerns that exist.
The Scale of Hydrogen Production and Its Impacts
Before diving into the numbers, let's consider the accompanying chart illustrating the production versus demand of hydrogen in 2021. The chart, based on data from IRENA and IEA, It's important to note a discrepancy: IEA data indicates a total hydrogen production of 94 million tonnes, while IRENA's figure is higher at 120 million tonnes. This difference highlights the challenges in accurately capturing global energy data. Despite this, the overall picture remains clear: a substantial portion of hydrogen production, almost 95%, relies on fossil fuels, with natural gas accounting for 47%, coal 27%, oil 22%, and only 4% from electrolysis. On the demand side, about 40% of this hydrogen, or 39.82 million tonnes, is used in oil refineries - industries directly linked to the fossil fuel economy we aim to transition away from. In order to avoid catastrophic climate change, a significant shift in this sector is crucial. The rest of the demand is distributed across chemicals 48.40 million tonnes, iron and steel 5.16 million tonnes, with other industries and sectors making up the rest. Even if we eliminate the portion of hydrogen used in oil refining, a staggering 60-90 millions tonnes per year would still be needed for various industries. This estimate assumes no growth in hydrogen demand, which might not be the case as industries evolve and the economy grows.
Green Hydrogen: A Path to Decarbonization & The Clean Hydrogen Ladder Concept
Assuming we can produce sufficient affordable green hydrogen through electrolysis, the focus should shift to decarbonizing hydrogen feedstocks for diverse industries. This strategy is key to reducing our overall carbon footprint without disrupting industrial processes that are vital for our economy. Given these dynamics, it might be premature to heavily invest in hydrogen as a fuel for transportation. While it's an exciting area of development, our immediate focus should be on areas where green hydrogen can replace its carbon-intensive counterparts most effectively. Michael Liebreich's Clean Hydrogen Ladder concept offers a clear visualization of this issue.
