Contributed to both SDN-microSENSE (microgrid resilience) and EnergyShield (vulnerability assessment and DDoS mitigation for critical energy infrastructure).
DIL DIEL
Bulgarian SME specializing in energy grid cybersecurity and sodium-ion battery technology for stationary storage applications.
Their core work
DIL DIEL is a Bulgarian SME that works at the intersection of energy systems and cybersecurity. They contribute to EU projects focused on protecting critical energy infrastructure — specifically microgrids and electrical power systems — from cyber threats, as well as developing next-generation sodium-ion battery technology for stationary applications. Their project portfolio suggests expertise in integrating IT security solutions into energy system architectures and supporting lifecycle assessment of emerging battery technologies.
What they specialise in
SDN-microSENSE focused on resilient electrical energy systems, and EnergyShield on monitoring and protecting critical energy infrastructure.
Participated in NAIMA, developing cost-effective Na-ion cells for stationary (non-automotive) energy storage applications.
NAIMA project included lifecycle assessment and lifecycle cost analysis of sodium-ion battery materials and cells.
How they've shifted over time
All three of DIL DIEL's H2020 projects started in 2019, making it difficult to identify a long-term evolution. However, the data shows two parallel tracks emerging simultaneously: securing critical energy infrastructure (two projects) and next-generation battery materials (one project). The common thread is energy systems — they appear to be positioning themselves where cybersecurity meets the energy transition.
DIL DIEL is building dual competencies in energy cybersecurity and battery technology — both areas with growing EU funding and industry demand as energy systems become more digital and distributed.
How they like to work
DIL DIEL operates exclusively as a participant, never leading projects, which is typical for a specialist SME contributing focused technical input to larger consortia. With 74 unique partners across just 3 projects, they work in large, diverse consortia (averaging ~25 partners per project). This suggests they are comfortable integrating into complex multi-partner environments and can work across many institutional cultures.
Despite only three projects, DIL DIEL has collaborated with 74 distinct partners across 18 countries, giving them a remarkably broad European network for an SME of their size. This pan-European reach makes them well-connected for a Bulgarian company in the energy-security space.
What sets them apart
DIL DIEL occupies an unusual niche combining energy system cybersecurity with battery technology knowledge — a rare combination for a Bulgarian SME. For consortium builders, they offer a cost-effective partner from an EU-13 country (useful for widening participation requirements) with genuine technical contributions in both energy security and energy storage. Their experience in large consortia across 18 countries means low onboarding friction for new partnerships.
Highlights from their portfolio
- EnergyShieldTheir largest funded project (EUR 116,812), addressing cybersecurity for critical energy infrastructure with SIEM, anomaly detection, and DDoS mitigation — highly relevant topics as energy grids digitalize.
- NAIMAA departure from their cybersecurity focus into sodium-ion battery materials for stationary storage, signaling diversification into the energy storage value chain.
