Amidst the dual challenges of climate change and an energy supply chain crisis triggered by geopolitical conflicts, the global energy paradigm is shifting faster than ever. This analysis provides an in-depth look at the current implementation of clean energy (hydrogen and nuclear fusion) roadmaps and the outlook for climate change (El Niño).
1. Global Clean Energy Roadmap & Implementation Status
Hydrogen fuel and nuclear fusion energy are considered the “end-game” technologies to replace fossil fuels. According to recently published roadmaps by the International Energy Agency (IEA) and leading nations, the current status is as follows:
Hydrogen Energy: Shifting from Vision to Feasibility
Moving beyond vague projections, the international community has entered the stage of building practical supply chains.
- Accelerating Existing Facility Conversion: Industrial process remodeling is well underway to replace grey hydrogen with eco-friendly clean hydrogen.
- Expanding Transport and Storage Infrastructure: Projects blending hydrogen into natural gas pipelines and maritime transport technologies utilizing hydroxide/ammonia forms are being implemented in line with international standards. However, large-scale water electrolysis facility investment to lower the unit cost of carbon-free “green hydrogen” remains a primary prerequisite.
Nuclear Fusion Energy: The Public-Private Commercialization Race
The world is aggressively locking in national roadmaps, significantly pulling forward the commercialization timeline of nuclear fusion to the mid-2030s. While maintaining cooperation on the International Thermonuclear Experimental Reactor (ITER), major countries are increasingly shaping their independent demonstration plans.
European Parliament – European Union
- United States: The Department of Energy (DOE) has finalized its national Fusion Science and Technology (FS&T) roadmap integrated with high-performance computing and artificial intelligence (AI), accelerating efforts to operate a pilot plant by the mid-2030s.
- European Union & United Kingdom: The EU has made massive additional investments under the Euratom program to form public-private partnerships. Meanwhile, the UK has confirmed the construction of its commercial fusion reactor (STEP) at the West Burton site, strengthening its supply chain.
- South Korea: Aiming to operate a demonstration reactor by 2035, the country is reinforcing its independent commercialization guidelines in magnetic confinement infrastructure and plasma control—the core technologies of fusion.
2. Global Climate Change & El Niño Forecasts
As the world, including Europe, experiences extreme heatwaves and climate anomalies, changes in Pacific sea surface temperatures hold the key to global climate trends.
Climate Outlook Summary
According to recent predictive data from the World Meteorological Organization (WMO) and other bodies, following a temporary lull, there is a high probability that the El Niño phenomenon will redevelop starting in the second half of 2026.
Assessment of Potential Improvement
Because climate phenomena alternate between El Niño and La Niña over multi-year cycles, temporary drops (improvements) in sea surface temperatures do occur. However, because the “underlying condition” of global warming caused by greenhouse gas emissions remains unresolved, the destructive power of El Niño hits record highs with every return.
- Upcoming Risks (2027 Warnings): Experts warn that 2027 could become the hottest year on record, as the full impact of the El Niño redeveloping in late 2026 hits the global atmosphere.
- Extreme weather events—such as widespread droughts and water shortages across Europe, alongside torrential rainfall in Asia and the Americas—are more likely to become entrenched rather than show short-term improvement. Consequently, establishing national-level infrastructure adaptation systems is an urgent priority.
