University of West Attica - UNIWA ( Former T.E.I. of PIRAEUS – TEIP) ranks among the top five technical universities of Greece, offering excellent academic, social and cultural infrastructure to over 26,500 students, while also actively engaging into research activities through participation and coordination of various EU-funded and national projects.

Grasping the trend towards the development of new structures that foster sustainability principles, UNIWA (Former TEIP) and the Mechanical Engineers Department (led by the Soft Energy Applications & Environmental Protection Lab-SEALAB) have during the recent years made a commitment to build a greener profile through e.g., the renovation of the university buildings and the installation of novel, demonstration technologies that serve the purposes of energy efficiency and renewable energy integration.

SEALAB (http://www.sealab.gr/), representing UNIWA (Former TEIP) in TILOS project, has long experience in the field of RES, with its ongoing research activities focusing on:

  • Novel Strategies for Increasing RES Integration
  • Policy Development & Economics of Energy Storage
  • Implementation of the Green Island Concept
  • Simulation Tools for Energy Storage (Battery Storage, PHS, CAES, H2)
  • Integrated Energy & Water Production-Supply
