“…The goal of ITER is to demonstrate sustainable deuterium-tritium plasma formation to create a 500 MW fusion power (Q = 10) for a duration of 300–500 s. 81 According to the roadmap of fusion energy development, the construction of demonstration power plants (DEMO) will be the last step before building a fusion power plant. China, 82 the EU, 83 and Japan 84 have carried out their studies on DEMO, and the engineering design of the Chinese Fusion Engineering Testing Reactor was completed in 2021.…”

Global development has been heavily reliant on the overexploitation of natural resources since the Industrial Revolution. With the extensive use of fossil fuels, deforestation, and other forms of land-use change, anthropogenic activities have contributed to the ever-increasing concentrations of greenhouse gases (GHGs) in the atmosphere, causing global climate change. In response to the worsening global climate change, achieving carbon neutrality by 2050 is the most pressing task on the planet. To this end, it is of utmost importance and a significant challenge to reform the current production systems to reduce GHG emissions and promote the capture of CO 2 from the atmosphere. Herein, we review innovative technologies that offer solutions achieving carbon (C) neutrality and sustainable development, including those for renewable energy production, food system transformation, waste valorization, C sink conservation, and C-negative manufacturing. The wealth of knowledge disseminated in this review could inspire the global community and drive the further development of innovative technologies to mitigate climate change and sustainably support human activities.

“…Currently, the EAST is becoming one of the key tokamaks in the world; it can provide high-performance, long-pulse operation scenarios for future devices, including the ITER, CFETR, and DEMO. The engineering design of the CFETR started in 2017, 13 which is about 10 years earlier than that of the EU-DEMO and Japan-DEMO, whose engineering designs are planned to commence in 2029 14 and 2025, 15 respectively.…”

“…For the next step devices, e.g., DEMO, [45,46,[48][49][50][51] or a future fusion reactor including Chinese experimental fusion test reactor, [52] the limits on power exhaust, availability, and lifetime are even more demanding, as conventional monoblocks are allowing for 10 MW m À2 , [20,21] and transmutation and radiation damage can quickly diminish the thermal conductivity to 50%. [53,54] Radiation effects including neutron embrittlement [55] do limit actively cooled W components in DEMO to about 3-5 MW m À2 due to the diminished thermal conductivity and the need to replace CuCrZr with steels with their low thermal conductivity.…”

Material issues pose a significant challenge for the design of future fusion reactors. From a historic point of view, the material mix used for the first wall of a fusion reactor has continually evolved, from original steel vessels to carbon and other low-Z materials such as beryllium to tungsten as the primary candidate for a reactor's first wall armor and divertor material. For materials considered for fusion applications, a highly integrated approach is necessary. Resilience against neutron damage, good power exhaust, and oxidation resistance during accidental air ingress are design relevant issues while deciding on new materials or improving upon baseline materials. Neutron-induced effects, e.g., transmutation adding to embrittlement, retention, and changes to thermomechanical properties, are crucial to material performance. In this contribution, the recent progress (2013-2019) in fusion materials development for current and future fusion devices, at Forschungszentrum Jülich GmbH, with activities focussing on advanced materials and their characterization is given. It is a continuation and extension of the work given by Coenen et al.
