O-CEI’s second Open Call

All the information about O-CEI 1st Open Call is now available. Access it via the link below.

Get up to €200,000 to replicate and deploy O-CEI Horizon Cloud-Edge-IoT technologies

O-CEI is a Horizon Europe Innovation Action advancing open, interoperable, and secure Cloud-Edge-IoT solutions through 8 Large-Scale Pilots across real-world sectors. O-CEI Horizon invites technology providers and end users to take these solutions further. Through the 2nd Open Call, selected consortia will replicate the O-CEI methodology, adopt its technologies, and demonstrate how they can be applied in new settings.

Who can apply?

We are looking for consortia of two entities combining:

A technology or service provider: an eligible SME, including startups.
An end user: any type of legal entity.

Both partners must be established in an EU Member State, including eligible Overseas Countries and Territories, or a Horizon Europe Associated Country.

What will selected projects receive?

Up to 8 projects selected
Up to €200,000 per project, shared between consortium partners
An 11-month support programme covering three stages:

Requirements & Design
Implementation
Demonstration

The opportunity to replicate O-CEI Horizon’s methodology and adopt its Cloud-Edge-IoT technologies
Support to develop a blueprint and configure a layout at proposal stage for later deployment using O-CEI Horizon platform tools and techniques

Key dates

Call opens: 12 November 2026, at 13:00 Brussels time
Application deadline: 14 January 2027, at 17:00 Brussels time

Advanced Microturbines

Can you briefly introduce your company and what you do?

Advanced Microturbines Srl is an Italian deep-tech SME specialised in the development of compact microturbine technologies for energy recovery and self-powered monitoring systems. The company designs and manufactures high-efficiency microturbines from 50 W to 50 kW capable of converting pressure drops in gas and water networks into electricity, enabling autonomous power supply for IoT sensors and digital infrastructure. Its solutions support the digitalisation and sustainability of energy and industrial systems by transforming unused pressure energy into a reliable source of power for remote monitoring applications. By combining microturbine technology with smart IoT systems, we deliver innovative solutions that support smart infrastructure, improve energy efficiency, and enable decentralised energy systems.

What challenge are you addressing under the O-CEI Horizon’s first Open Call, and how is your proposal relevant to the challenge?

Our proposal addresses the challenge of enabling transparent, secure, and real-time management of energy flows in decentralised energy systems, particularly in emerging smart microgrids. As renewable generation becomes increasingly distributed, local energy communities require reliable mechanisms to measure, validate, and share energy data between multiple actors. However, current infrastructures often rely on centralised systems, not distributed ones.

The ENTRUST solution tackles this challenge by developing an edge-validated blockchain platform for energy transactions. The system integrates IoT metering, edge computing, and blockchain notarisation to create a distributed architecture capable of securely validating energy data close to where it is generated. This approach enables real-time, low-latency processing while ensuring data integrity and transparency through blockchain mechanisms.

By combining edge processing with blockchain-based verification, the proposed platform allows microgrid participants, including households, local producers, and community operators, to securely record and validate energy exchanges. This contributes directly to the goals of the O-CEI Horizon’s Open Call by supporting decentralised, trustworthy, and scalable digital infrastructures for energy communities and smart grids.

What is the expected impact of your proposal?

The expected impact of the proposal is the development of a secure and transparent operational layer for decentralised energy systems, enabling more efficient management of renewable energy within local microgrids.

Through the integration of IoT metering, edge computing, and blockchain notarisation, the ENTRUST platform allows energy transactions and operational data to be securely recorded, validated, and shared in real time. This improves transparency and trust among microgrid participants while ensuring the integrity of energy data used for operational decisions and potential energy trading mechanisms.

The project will demonstrate the solution in the Krk Island pilot, showing how local communities can manage renewable energy generation and consumption more effectively. By enabling tamper-proof data validation and automated smart-contract processes, the platform supports fair and auditable energy exchanges between producers, consumers, and community operators.

Beyond the pilot, the modular and scalable architecture of ENTRUST allows the platform to be replicated in other energy communities and distributed energy systems across Europe. In this way, the project contributes to the broader objectives of the European energy transition, supporting the integration of renewable energy, strengthening local energy resilience, and enabling new models of transparent and decentralised energy management aligned with EU climate and energy policies.
