In Wolfenstein: Youngblood, last title of the Wolfenstein saga, produced by Bethesda, there are three different types of Kraftwerk doors: each of these requires a different weapon to be unlocked, thanks to the skills needed to open the grids. While not crucial to the title, the Kraftwerks contain many of the game's collectibles.
The weapons you will need are: Laserkraftwerk, Dieselkraftwerk and Elektrokraftwerk. For the Laserkraftwerk, (which you will find in Brother 1), Go to the underground section of the prison and find the sealed office. You can go down inside the office through the ventilation duct and then take the weapon from the nearby armory. Thanks to the Laserkraftwerk, you can open sealed doors which, however, can also be passed through using the Lasergewehr.
To get the Dieselkraftwerk in Brother 2, you have to go to the yellow door with the keypad and look behind it. There will be another room under the garage. where you will see a robot. Destroy the anchors holding the stairs in place and you will find the Dieselkraftwerk. Use it to open the doors with the orange marks.
The Elektrokraftwerk is located in Brother 3. After reaching the workshop with the super soldiers, look up to notice a gap. Climb up and through it to get to a test room which contains the Elektrokraftwerk. You will need to use this weapon when you are near energy groups to get through the doors connected to them.
To open the Kraftwerk grids in Wolfenstein Youngblood, you will need the "Crush" ability., obtainable for the cost of 5 skill points. Try to unlock it as soon as possible so as not to preclude you from any alternative way throughout the game.
