Greek technology SME specialising in nanotechnology applications for energy storage materials and smart lightweight composites.
Pleione Energy is a Greek technology SME (whose name translates to "innovative energy applications") working at the intersection of advanced materials, nanotechnology, and energy technology. In practice, they contribute applied industrial expertise to research consortia tackling nano-enabled materials — from lightweight smart composites to the characterisation of battery electrolyte interfaces at the nanoscale. Their role in H2020 has been as a technology partner bringing real-world application context to more research-heavy consortia, helping bridge laboratory discoveries toward industrial use. Their work spans GHz-range dielectric measurement techniques, nano-composite material performance, and open innovation infrastructure for materials scale-up.
In NanoBat (2020-2023), Pleione contributed to GHz nanoscale electrical and dielectric measurements of solid-electrolyte interfaces in batteries, indicating direct expertise in nanoscale energy material characterisation.
In OASIS (2019-2022), they worked on scale-up of nano-enabled, lightweight, multifunctional smart composite materials through an open innovation test bed structure.
OASIS was specifically structured as an Open Access Single Entry Point for SMEs scaling up advanced materials, a model Pleione actively participated in as an industrial partner.
NanoBat keywords include microscopy, microwaves, and GHz technology, pointing to specialised high-frequency characterisation techniques applied to nanomaterials.
Pleione's two-project trajectory shows a deliberate move from broad nano-composite materials toward a focused energy storage niche. Their first project (OASIS, 2019) was about open innovation infrastructure and the general scale-up of smart lightweight composites — the keywords reflect a wide materials platform. By their second project (NanoBat, 2020), the focus had narrowed sharply to battery electrolyte characterisation using GHz nanotechnology, microscopy, and dielectric measurement. The direction is clear: they are moving from general advanced materials toward energy storage materials specifically, which aligns with their company name and likely their core commercial interest.
Pleione appears to be narrowing toward battery material science and nanoscale measurement, making them a relevant partner for projects in solid-state batteries, electrolyte interface engineering, or energy storage diagnostics.
Pleione has participated exclusively as a consortium partner — never as a coordinator — across both projects. Their engagement in large consortia (32 unique partners across 10 countries from just 2 projects) suggests they are comfortable operating within complex multi-partner structures rather than driving them. This profile is consistent with an industrial SME that brings domain-specific application expertise to consortia where research institutes and universities provide the academic core.
Despite only two projects, Pleione has built a surprisingly broad network of 32 unique partners spanning 10 countries — suggesting both projects were large, multi-partner initiatives. Their reach is firmly European, with no indication of partnerships beyond the EU context.
Pleione is a rare example of a small Greek private company active in high-precision nanotechnology and advanced energy materials — a niche that Greek SMEs rarely occupy in H2020 data. Their combination of composite materials experience (OASIS) and battery electrolyte characterisation (NanoBat) makes them a credible industrial bridge partner for materials-to-energy-storage pathways. For a consortium that needs an SME voice from Southern Europe with hands-on nanotechnology application background, Pleione fills a gap that most participants cannot.
