In a fossil-free global energy future, renewables must be supported by large-scale contributions from other sustainable energy sources. Fusion, reactions between light atomic nuclei, offers safe, economic and environmentally benign energy, using abundant and widely available fuel without production of neither greenhouse gases nor long-lived waste. If politically and economically supported, the fast track of fusion leads to commercial electricity production by the middle of the century.
To receive sufficient funding for development in due time, both nationally and internationally. To further reduce turbulence of the hot fusion fuel, the plasma, that leads to energy leakage. To develop wall materials that better withstand the heat surface loading and strong neutron flows. To develop innovative magnetic confinement schemes that will provide smaller and more economic power stations.
These are the research groups in KTH's school organisation performing research related to fusion.
