Superconducting confined plasma energy storage

What is the key to magnetic confinement of plasma?

The key to magnetic confinement of plasma, and therefore, to controlled fusion, is to generate the adequate magnetic flux surfaces in the volume containing the plasma and to maintain these magnetic surfaces in the event of plasma instabilities or turbulences 2, 3, 6, 13, 14, 15, 16.

Can magnetically confined plasma generate net energy?

The fusion created by magnetically confined plasma is a promising clean and essentially unlimited future energy source. However, net energy generation has not been yet demonstrated in fusion experiments. Some of the main problems hindering controlled fusion are the imperfect magnetic confinement and the associated plasma instabilities.

Can a superconducting toroid create a fully confined magnetic field?

Some of the main problems hindering controlled fusion are the imperfect magnetic confinement and the associated plasma instabilities. Here, we theoretically demonstrate how to create a fully confined magnetic field with the precise three-dimensional shape required by fusion theory, using a bulk superconducting toroid with a toroidal cavity.

Can magnetically confined plasma fusion be controlled?

Scientific Reports 14, Article number: 3653 (2024) Cite this article The fusion created by magnetically confined plasma is a promising clean and essentially unlimited future energy source. However, there are important problems hindering controlled fusion like the imperfect magnetic confinement and the associated plasma instabilities.

Can high-temperature superconductors be used to construct a bulk superconducting toroid?

Current high-temperature superconductors can be employed to construct the bulk superconducting toroid. This can lead to optimized robust magnetic confinement and largely simplified configurations in future fusion experiments. One of the main challenges of our society is to produce clean energy in ways that do not damage the environment.

What is the plasma pressure in magnetic confinement D/T reactions?

The plasma pressure that can be achieved is limited by the magneto hydro dynamic instability limits, denoted as β, associated with the confining magnetic field pressure. In magnetic confinement D/T reactions, the output power density is proportional to β2 and B4, where B is the strength of the magnetic field.
