PPorous Energy Technologies
Porous Energy Technologies is a deeptech spin-off of the Universidad Autónoma de Madrid developing next-generation supercapacitor electrodes based on the synergy between graphene and covalent organic frameworks (COFs). Its patented 3D microfluidic printing process produces customisable, low-cost and sustainable electrodes with reported capacitances of up to 233 F/g, targeting high-energy-density energy storage. The company was incorporated in Madrid in October 2025 and is based at the Fundación Parque Científico de Madrid; it is very early stage.
