Disadvantages of nuclear fusion

Later, tritium could be produced in the nuclear fusion reactors themselves. This means that nuclear fusion could provide energy for centuries or even millennia. In theory, a fusion power plant of the future could generate one to two gigawatts of electricity. In comparison, the currently most powerful nuclear reactor generates around 1.6 gigawatts of electricity.

Despite its promising potential, nuclear fusion also has a number of disadvantages compared to renewable energy sources and nuclear energy.

Low technological maturity: Nuclear fusion is still in the research and development phase and is not yet a viable source of energy. Although scientists have made significant progress in understanding the physics of nuclear fusion, the technology to use this energy on a large scale has yet to be developed. A number of experimental reactors are currently germany consumer email list in operation or are still being built, such as the International Thermonuclear Experimental Reactor (ITER) in southern France. This is still in the test and demonstration phase. In contrast, technologies for using renewable energy are becoming increasingly efficient and more mature.
High initial input energy: Nuclear fusion reactors require a significant amount of energy to start and maintain the fusion reaction. This energy must come from an external source - such as a conventional power plant. This means that nuclear fusion power plants still require fossil fuels or other energy sources to start up. Renewable energy technologies, on the other hand, rely only on the energy of nature as an input.
High costs: The development, testing and construction of nuclear fusion power plants require investment costs of several billion euros. These expensive power plants are difficult for countries with limited resources to finance.
