Module 1 integrates the existing experimental base on topics with which each partner is involved in NI ESHER. It is designed to support developments at Technology Readiness Level (TRL) 1-3.  Module 1 brings together ten thematic laboratories, each administratively managed by an institute or university partner in NSI ESHER. The ten thematic laboratories are grouped into two integrated thematic laboratories at the partner level:

• Integrated thematic laboratory "Research and testing of batteries for energy storage systems
• • Integrated thematic laboratory “Hydrogen energy with renewable energy”

Module 2 aims to establish an experimental foundation for developing demonstration projects with industry (NTG developments over 4). This module will establish an experimental platform that is not included in other national infrastructure projects.

• Technological platform “Technological development of a new generation of batteries”. This platform will address the country's lack of an experimental base for scaling up laboratory prototypes, which requires new technological solutions and equipment.

Module 3 complements the infrastructure's functionality by organizing scientific events, such as thematic seminars, workshops, training sessions, demonstrations, and conferences, to support knowledge exchange and build an active scientific community.

Additionally, Module 3 includes reporting and monitoring activities related to the implementation and impact of the infrastructure. It ensures the systematic collection and analysis of data on resource usage, scientific activity results, and the degree of external user involvement.

The laboratory brings together existing equipment and long-standing expertise in a wide range of activities related both to the development of new materials and to innovative electrochemical and physical methodologies for their characterization. At the core of its activities are the "Electrode materials for batteries and supercapacitors" and "Battery testing" laboratories, which have the potential to conduct fundamental and applied scientific research on high-efficiency energy storage systems. The laboratory possesses expertise at both national and international levels and has well-established connections with the Bulgarian industry.

The laboratory carries out coordinated activities in the preparation, characterization, and testing of a wide range of objects with specific applications using the integrated material base and expertise of partner laboratories located in several scientific institutions. By establishing a national research space with modernized and upgraded equipment, the integrated thematic laboratory supports the implementation of complex fundamental and applied research, as well as the deployment of innovative technologies for renewable energy storage and its efficient use in households and industry.

The platform addresses the infrastructural gap for scaling up cutting-edge laboratory developments (with technology readiness levels above 4) in several national and European projects. It provides opportunities to advance to the demonstration and deployment phases. It is organized as a single laboratory that enables the scaling up of battery innovations.
