by MS Khan · 2025 · Cited by 3 — Fusion promises inherent advantages over conventional sources, including abundant fuel supply, the absence of greenhouse gas emissions
**CLICK HERE** to register for the 3rd Public-Private Fusion Workshop at ITER (28-29 April 2026). # Advantages of fusion. **Millions of years**: Fusion in ITER will require two elements: deuterium and tritium. (Terrestrial reserves of lithium would permit the operation of fusion power plants for more than 1,000 years, while sea-based reserves of lithium, used in a fusion reactor in its Li-6 isotope form, would fulfil needs for millions of years.) A critical challenge is how to breed and recover tritium reliably in a fusion device. (Radioactive tritium is neither a fissile nor a fissionable material.) There are no enriched materials in a fusion reactor like ITER that could be exploited to make nuclear weapons. As a new source of carbon-free baseload electricity, producing no long-lived radioactive waste, fusion could make a positive contribution to the challenges of resource availability, reduced carbon emissions, and fission waste disposal and safety issues. ### What is Fusion? ITER is charting new territory in fusion research.
# Op-ed: Fusion power is a strong alternative energy source. While yet to be commercialized, it is clear that fusion has the potential to be a great alternative even to renewable energy sources due to its lack of harmful emissions and of radioactive waste, its abundant fuel stores and consistency (Whyte, 2016). Finally, unlike renewables such as solar and wind, nuclear fusion is not at the mercy of environmental conditions meaning it can be controlled to always meet energy demand. So far, they have been able to produce some fusion energy but it requires many times more energy to power the facility than what they get from the fusion reaction. This heat and magnetic force essentially cause the fusion of the atoms and the release of energy. Christopher is interested in advancing fusion power as an alternative energy source. Op-ed: Fusion power is a strong alternative energy source was originally published in Berkeley Master of Engineering on Medium, where people are continuing the conversation by highlighting and responding to this story.
Unlike coal or natural gas power plants, fusion does not emit harmful pollutants like sulfur dioxide or nitrogen oxides, which cause acid rain
# Why Fusion? Capable of operating 24 hours a day and 7 days a week, a fusion power plant would complement renewable energy sources while meeting the growing global need for energy. Amid increasing demand and limited land area, fusion will deliver clean energy to more people while taking up less space than other power sources. Fusion is inherently safe because it only occurs under precise conditions. The fuel for a fusion power plant can easily be extracted from seawater. Because fusion creates so much energy and can operate anywhere in the world using readily available fuel, it has the potential to power the world cleanly and equitably, indefinitely. ### What is Fusion? ### Fusion in the United States. Illustration: Fusion in the United States. ### Approaches to Fusion. Four broad categories define how to produce fusion energy. ### A History of Fusion. Nearly a century of fusion energy progress.
Fusion promises no long lived radioactive waste, an abundant and self-sufficient fuel cycle, the creation of helium (a scarce element) and
