Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

Pure gold-copper alloys are known to be difficult to electrodeposit because of a strong variation in composition after a few microns have been deposited. Commissariat à l’Energie Atomique (CEA) studied the phenomenon and showed that the decrease in gold’s content is accompanied by an evolution of the microstructure that could be attributed to the free cyanide released near the cathode. During electrolysis, free cyanides provoke a decrease of the copper overpotential (until copper reduction is stopped) and promote the formation of Cu(CN)43− that conduct to an instantaneous three-dimensional nucleation of copper. This phenomenological model well explains why the growth mechanism changes and why only gold is deposited for thick deposits. On the basis of this model, CEA has developed a specific process using ultrasonic waves in order to remove the free cyanides from the cathode. This process allows CEA to perform thick gold-copper deposits with a constant concentration in copper through all the thickness. By controlling the applied potential, different thick alloys with a concentration of copper between 0 wt% up to 40 wt% can be deposited.
