Fusion energy presents a promising pathway to achieving a sustainable and nearly inexhaustible energy supply. The deuterium–tritium (D–T) fusion reactions are considered a viable alternative to fossil fuels, significantly reducing their environmental impact while meeting global energy demands. In contrast to traditional nuclear energy, fusion generates much less long-lived radioactive waste and does not emit carbon dioxide, positioning it as a transformative clean energy source with an energy [...] with fission being avoided. The primary byproduct, helium, is inert and environmentally harmless. Additionally, fusion is considered sustainable, as abundant resources like deuterium from water and tritium, which can be bred from lithium, are utilized, ensuring a virtually limitless supply of fuel for the future. [...] .")]. Light atomic nuclei combine to produce fusion energy, which can replace nuclear fission and fossil fuels. Fusion, unlike fission, produces less radioactive waste and uses saltwater (deuterium) as a sustainable fuel source . Chemical energy sources exhibit significantly lower energy density than fusion [10:2458–68.

2. Abundant Fuel Supply: Fusion fuel sources, such as deuterium and tritium, can be extracted from seawater and are virtually inexhaustible. With an ample supply of fuel, fusion energy offers long-term energy security and relief from concerns over resource scarcity.
3. Safety and Waste Reduction: Fusion is self-limiting, making it inherently safe. Moreover, fusion machines are being tailored to not generate high level radioactive waste, making fusion a responsible and sustainable energy option. [...] Fusion energy is a natural phenomenon, the very process that powers the Sun and helps make life on the Earth possible. In a fusion reaction, two light nuclei merge to form a single heavier nucleus when the right temperature, density, and time length conditions are met. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy following the famous Einstein equation (E=mc2). [...] 1. Zero Carbon Emissions: Unlike fossil fuels, fusion energy emits no greenhouse gases during the fusion process. By transitioning to fusion power, we can significantly reduce our carbon footprint, preserve natural resources, and foster a cleaner environment for future generations.

A month later in the UK, scientists at the Joint European Torus laboratory (JET) announced they’d generated a record-breaking 59 megajoules of sustained fusion energy – double the previous record energy output and a further boost for their partners at the ITER project (for which it is acting as a prototype of sorts). [...] Additionally, nuclear fusion does not produce carbon dioxide or long-lived nuclear waste, making it a highly sustainable option. However, creating the right conditions in a fusion reactor has proven to be a challenging and costly process.
## International Collaboration [...] In China, in January 2022, the EAST reactor broke the record for the longest sustained nuclear fusion with temperatures of 126 million degrees Fahrenheit - roughly five times hotter than the sun – sustained for 17 minutes.
China’s EAST reactor is being used to test the technology for the ITER reactor in the south of France, with some estimates now forecasting it could begin working as soon as 2025.

# Fusion energy
Fusion takes place in the hearts of stars and provides the power that drives the universe. It promises to be a safe, low carbon and sustainable part of the world’s future energy supply.
A view of the Earth from space showing the blue glow of dawn on the sea and glowing city lights in the shadow of the night. [...] UKAEA leads the world in fusion energy research. We have a wide range of programmes covering plasma science, robotics, materials testing and development, and tritium science.
Our scientists and engineers are working with partners in the UK and around the globe. They are developing the technology to sustain this process on Earth to create a new source of sustainable energy.
## Fusion energy in brief [...] We worked with the Sustainable Markets Initiative Fusion Task Force and the Energy Institute to produce this guide to fusion energy.

FUSION ENERGY
# Advantages of fusion
## A new large-scale, sustainable and carbon-free form of energy is urgently needed.
The next decades are crucially important to putting the world on a path of reduced greenhouse gas emissions. [...] By the end of the century, demand for energy will have tripled under the combined pressure of population growth, increased urbanization and expanding access to electricity in developing countries. The fossil fuels that shaped 19th and 20th century civilization can only be relied on at the cost of greenhouse gases and pollution.
A new large-scale, sustainable and carbon-free form of energy is urgently needed. The following advantages make fusion worth pursuing. [...] The ideal future energy mix for the planet would be based on a variety of generation methods instead of a large reliance on one source. 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.

Scientists are working to replicate fusion on Earth as a means to generate electricity for the power grid. Fusion energy would provide the benefit of a lasting power source that doesn't produce greenhouse gases or significant amounts of long-lived radioactive waste.

The MIT Plasma Fusion Center in 1980. [...] Fusion reactions take place in a state of matter called plasma, a super-hot, charged gas made of atomic nuclei and free-moving electrons. Because all nuclei are positively charged, they repel each other, preventing fusion under most conditions. However, the extreme heat of plasma causes the nuclei to move so fast that they overcome this repulsion, collide and then fuse. A confined plasma housing millions of these reactions every second can generate vast amounts of energy from very little fuel. [...] By Ariela Haber
The U.S. National Science Foundation invests in an array of projects and programs that advance fusion research and development, which are bringing society closer to conquering one of its biggest science and engineering challenges.
Nuclear fusion is the energy source of stars, including our sun. It occurs when two atomic nuclei, such as hydrogen isotopes, combine to form a new nucleus, which releases energy.

[edit]
Fusion power promises to provide more energy for a given weight of fuel than any fuel-consuming energy source currently in use. The fuel (primarily deuterium) exists abundantly in the ocean: about 1 in 6500 hydrogen atoms in seawater is deuterium. Although this is only about 0.015%, seawater is plentiful and easy to access, implying that fusion could supply the world's energy needs for millions of years. [...] Retrieved from ""

ITER represents an investment of over twenty billion dollars, and possibly tens of billions more, including in kind contributions. Under the European Union's Sixth Framework Programme, nuclear fusion research received €750 million (in addition to ITER funding), compared with €810 million for sustainable energy research, putting research into fusion power well ahead of that of any single rival technology.

For many decades, fusion has been touted as the ultimate source of abundant, clean electricity. Now, as the world faces the need to reduce carbon emissions to prevent catastrophic climate change, making commercial fusion power a reality takes on new importance. In a power system dominated by low-carbon variable renewable energy sources (VREs) such as solar and wind, “firm” electricity sources are needed to kick in whenever demand exceeds supply — for example, when the sun isn’t shining or the [...] 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.” [...] Overall, the analyses showed that — while the technology demands of harnessing fusion energy are formidable — so are the potential economic and environmental payoffs of adding this firm, low-carbon technology to the world’s portfolio of energy options.
