Hydrogen Demand Projections: A Shift Towards Reality by 2100
Written on
Chapter 1: Overview of Hydrogen Demand
In the past two years, I have revised my hydrogen demand projections for 2100, largely driven by Michael Liebreich's latest update to his hydrogen ladder. This newly published version highlights significant shifts in hydrogen demand across various sectors, particularly in iron and steel, where I have recently adjusted my forecasts.
Section 1.1: The Context of Hydrogen Manufacturing
Hydrogen production today poses a considerable challenge regarding greenhouse gas emissions, comparable to the entire aviation sector, emitting approximately 1.5 billion tons of greenhouse gases annually. Transitioning to low-emission hydrogen production methods is essential, but it incurs substantial costs, potentially increasing the price of hydrogen by three to five times per ton.
Section 1.2: Steel Manufacturing - A Growth Sector
The steel industry represents a unique area of growth within hydrogen demand. Originally, I projected a requirement for around 40 million tons of hydrogen for steel production. However, as China's rapid industrial growth stabilizes, I have adjusted this figure down to approximately 30 million tons by 2100. This is due to a higher reliance on recycled steel in electric arc furnaces, which the U.S. has successfully implemented for years.
Chapter 2: Transportation and Hydrogen's Role
The first video titled "Hydrogen could power nearly a quarter of the world's energy needs by 2050!" explores the potential role of hydrogen in future energy systems. Despite the excitement, my analysis suggests hydrogen's application in transportation—whether directly or through synthetic fuels—will likely be minimal. The high costs associated with blue hydrogen, compounded by its lower energy yield compared to natural gas, make it an unviable option.
The second video titled "Recent reports show a booming hydrogen economy, with demand set to skyrocket in the coming decades" discusses the expected growth in hydrogen applications. However, my findings indicate that most transportation sectors will transition to battery-electric systems, leaving hydrogen with a minimal role.
Section 2.1: The Status of Refineries
Oil refineries currently dominate hydrogen demand, consuming about 40 million tons, primarily for hydrocracking processes. However, as global oil demand peaks, the requirement for hydrogen in these processes will decline, leading to a significant reduction in the overall hydrogen market.
Section 2.2: The Future of Fertilizers and Ammonia
Ammonia production, which heavily relies on hydrogen, faces challenges as agricultural practices evolve. The projected demand for hydrogen in fertilizer production is expected to decrease, driven by initiatives to enhance nitrogen-fixing capabilities in crops and decreasing over-application of fertilizers.
Section 2.3: Heating and Hydrogen's Decline
Research shows that hydrogen is unlikely to play a significant role in heating applications. With advancements in heat pump technologies and rising costs associated with hydrogen, electricity is set to become the more economical choice for heating solutions.
Section 2.4: Long-Term Storage Considerations
While some discussions posit hydrogen as a potential solution for long-term energy storage, alternatives like pumped hydro and battery systems are more viable. Hydrogen’s inherent inefficiencies and higher costs make it less desirable for this application.
Chapter 3: Conclusion on Hydrogen Demand
The cumulative effect of these considerations leads to a downward revision of my hydrogen demand projections for 2100. Initially estimated at 90 million tons, the new forecast stands at just under 80 million tons. This shift reflects a growing understanding of economic realities and the limitations of hydrogen across various applications.
In summary, while hydrogen has been heralded as a versatile energy source, the projections indicate a more cautious outlook as we approach 2100. The dynamics of supply, demand, and technological advancements will play pivotal roles in shaping the future of hydrogen's role in our energy landscape.
