Kraftblock entwickelt, berechnet und baut Anlagen für klimaneutrale Prozesswärme in Industrie, Fernwärme und Stromerzeugungsanlagen. Kern der Anlagen ist ein eigens entwickelter thermischer Energiespeicher, der bis zu 1,300°C in nachhaltigem Material speichert. Das Hauptaugenmerk ist die Dekarbonisierung von Energie in Industrien wie Stahl, Glas, Chemie, Keramik und Zement. In Verbindung mit Elektrifizierung und Speicher können fossile Brennstoffe in Industrien wie Lebensmittel und Getränke, Papier, Gummi, Bergbau und viele weitere mit dem Kraftblock-System ersetzt werden. Kraftblock wurde 2014 von Chemiker und Materialwissenschaftler Dr. Martin Schichtel und Ökonomin Dr. Susanne König gegründet.
