New world record set for energy from nuclear fusion

The European Fusion Program (EUROFusion), which includes the fusion experiment facility JET located near Oxford, England, made a statement regarding the record.

Accordingly, scientists using JET, known as tokamak, achieved a record fusion energy of approximately 69.3 megajoules for 5 seconds using 0.21 milligrams of fuel. The team’s previous world record was 59 megajoules of fusion energy in 2022.

Scientists fed the tokamak with deuterium and tritium, variants of hydrogen.

The team raised temperatures in the machine to 150 million degrees Celsius to generate fusion energy, and this extreme heat allowed deuterium and tritium to combine to form helium and release a huge amount of heat.

“This experiment is the latest of its kind for JET, which has been operating for more than 40 years, and is promising news for new fusion projects,” said Ambrogio Fasoli, EUROfusion’s Chief Executive Officer.

“By using the same fuel mix used in commercial fusion power plants, we are able to reliably create fusion plasmas and demonstrate the advanced expertise developed over time,” said Dr. Fernanda Rimini, JET Senior Utilization Manager and JET Scientific Operations Leader.

Nuclear fusion is defined as the fusion of two lighter elements (hydrogen) into a heavier element (helium), releasing tremendously high energy.

Nuclear fusion, which is seen as an endless source of clean energy because it does not emit carbon and does not emit radiation, requires an environment of high heat, energy and density to take place.

In the center of the sun, high gravitational pressure allows fusion to take place at 10 million degrees Celsius, while on Earth, fusion is possible at least at 100 million degrees Celsius due to the low pressure.
