The use of plasma non-equilibrium in the mitigation of the enormous heat and particles fluxes in divertor sections of fusion reactors is probably the key to the success of fusion. Detailed studies on plasma detachment in combination with advanced control and the use of alternative divertor concepts are needed to provide answers to this fusion challenge. Some of the highlights in recent years investigated at the Plasma-Surface-Interaction facilities (Magnum-PSI and Pilot-PSI) will be discussed.
On the shorter term, sustainable energy generation by means of photovoltaics or wind will form a significant part of the energy mix. The intermittency as well as the temporal variation and the regional spread of this energy source, however, requires a means to store and transport energy on a large scale. Moreover, when fossil fuels resources dry up, ways of carbon dioxide re-use to provide platform molecules will be required. In this presentation, plasma chemistry as a means to convert renewable electricity into fuels and chemical feedstock will be discussed. Results on activation of CO2 by microwave generated plasma, attaining over 50% energy efficiency, will be discussed.
