Fusion energy releases no greenhouse gasses, and a power plant could be built anywhere. The main fuel source, hydrogen, is readily found in
Controlled fusion reactors could generate high levels of power with uninterrupted delivery and no greenhouse gas emissions. The fusion process produces far
The statistics reflect an even more dire condition for the Arab world with some countries almost fully relying on fossil fuels for energy production as shown in Fig. 1. Fossil fuels are the leading cause of global climate change, responsible for more than 75% of global greenhouse gas emissions and almost 90% of all carbon dioxide emissions [3]. To counteract the aforementioned effects of fossil fuels, it is essential to recognize that nuclear energy is the largest source of carbon-emission-free electricity production where continuous and reliable supply is needed, as shown in Fig. 2. The deuterium-tritium (D-T) reaction is the most promising for fusion power, releasing energy as a result of the mass difference between the initial reactants and the produced helium-4 and neutron. The energy produced from just 1 gram of deuterium-tritium fuel in a fusion reaction is equivalent to the energy generated by burning about 2,400 gallons of oil [7].

# Potential contribution of fusion power generation to low-carbon development under the Paris Agreement and associated uncertainties. This paper assessed the potential contribution of fusion power generation to low-carbon development, which is prescribed in the Paris Agreement, under the combination of different uncertainties of future socioeconomic development, probability of the 2 °C target, and development of commercial fusion power plants. Global negative CO2 emission in 2100 by drastic decarbonization of energy systems was required to achieve the 2 °C target, and fusion power plants were expected to be installed in the latter half of the 21st century mainly in countries with limited potentials of zero-emission energy sources, such as Japan, Korea, and Turkey, for cost-efficient climate change mitigation. If inexpensive power plants could be developed by enhanced R&D and advanced design in DEMO projects or if the establishment of fission plants in the future is low, fusion power generation will also be deployed in the EU28, India, and China.
The global energy landscape is increasingly challenged by rising demands and the urgent need for sustainable solutions, highlighting the importance of exploring alternative energy sources like fusion. This study reviews recent advancements in fusion technology, demonstrating its potential to provide a clean, virtually limitless energy source while addressing significant environmental concerns and contributing to global carbon reduction goals. Fusion technology can conserve more energy than both fossil fuels and renewable sources. This review paper examines the advancements in fusion energy research and the challenges facing its potential as a global energy source. A significant challenge in fusion energy research is achieving the “breakeven” point, where the energy generated from fusion reactions equals or surpasses the energy input required to sustain them [19:1851–64. Global fusion research receives support from initiatives like the EU’s Horizon 2020, the U.S. Department of Energy’s ARPA-E, and private investments from companies like CFS and TAE Technologies [33:1–15.
What is the potential role and value of fusion power plants (FPPs) in such a future electric power system — a system that is not only free of carbon emissions but also capable of meeting the dramatically increased global electricity demand expected in the coming decades? The value of having FPPs available on an electric grid will depend on what other options are available, so to perform their analyses, the researchers needed estimates of the future cost and performance of those options, including conventional fossil fuel generators, nuclear fission power plants, VRE generators, and energy storage technologies, as well as electricity demand for specific regions of the world. And for companies developing fusion technologies, the study’s message is clearly stated in the report: “If the cost and performance targets identified in this report can be achieved, our analysis shows that fusion energy can play a major role in meeting future electricity needs and achieving global net-zero carbon goals.”.
# Will nuclear fusion help solve our future energy needs? 👉 **In this article, we’ll explore nuclear fusion, its benefits and technological challenges, and its potential to address our future energy needs while combating climate change.**. While nuclear fusion has been achieved in experimental settings, sustaining a controlled fusion reaction that produces more energy than it consumes remains a challenge. However, scientists are making exciting advances toward this goal, and if successful, nuclear fusion could revolutionise our energy landscape by providing a powerful, sustainable alternative to fossil fuels. Nuclear fusion research has seen significant advancements over the past few decades, bringing us closer to achieving practical fusion energy. ## When can we expect nuclear fusion to become a viable energy source? Sustained investment and international cooperation are critical to the success of nuclear fusion as a viable energy source. **The achievement of commercial-scale nuclear fusion and its integration into the energy mix would mark a significant milestone in the global effort to mitigate climate change.
**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.
