2022 roadmap on 3D printing for energy

Abstract The energy transition is one of the main challenges our society and therefore a major driver for scientific community. To ensure smart to sustainable future scenario different technologies such as harvesting using solar cells or windmills chemical storage in batteries, super-capacitors hydrogen have be developed ultimately deployed. New fabrication approaches based on additive manufacturing digitalization industrial processes increase potential achieve highly efficient required competitiveness clean against fossil fuels. In this frame, present roadmap highlights tremendous 3D printing new route fully automate devices designed digital files. This article gives numerous guidelines maximize performance efficiency next generation printed while reducing waste critical raw materials. particular, paper focused current status, expected advances most relevant fuel electrolysers, cells, super-capacitors, thermoelectric generators, reactors turbomachinery.
