NGI Open Calls

Through an agile and flexible process, following the Horizon 2020 cascade funding mechanism, ongoing NGI Research and Innovation Actions (RIAs) provide support to projects from outstanding academic researchers, hi-tech startups and SMEs.

Funding is allocated to projects using short research cycles targeting the most promising ideas. Each of the selected projects pursue their own objectives, while the NGI RIAs provide the programme logic and vision, technical support, coaching and mentoring, to ensure that projects contribute towards a significant advancement of research and innovation in the NGI initiative.

The focus is on advanced concepts and technologies that link to relevant use cases and that can have an impact on the market and society over all. Applications and services that innovate without a research component are not covered by this model.



Opening date: Continuous submission with the following cut-off dates:

  • 13 July 2021

Closing date: Cut-off submission dates every two weeks (with few exceptions):

  • 7 September 2021

Short description: Fed4FIRE+ is the largest federation worldwide of NGI testbeds, which provides open, accessible and reliable facilities supporting a variety of different research and innovation communities and initiatives in Europe.

The goal of the Continuous Call is to make the federated infrastructure directly available for the execution of innovative projects from SMEs or from other parties (also not restricted to SMEs) who have successfully completed an experiment or project in the framework of one of the Open calls of any of the other NGI-projects: NGI Pointer, NGI Assure, NGI0 Discovery, NGI ESSIF-Lab, NGI Atlantic.EU, LEDGER, NGI DAPSI, NGI TRUST, NGI ZERO, NGI EXPLORERS, NGI0-PET, Ontochain and TREBLO. The submission requires a very limited-sized proposal for a short-duration experiment.

Target participants: Proposals will only be accepted from a single party eligible for participation in EC H2020-projects. Proposals can only be accepted from:

  • SMEs;
  • Parties who have successfully participated in one of the Open Calls of an H2020 NGI project.

Opening date: 19 May 2021

Closing date: Feasibility check: 31 August 2021, 17:00 CET  // Final submission: 07 September 2021, 17:00 CET

Short description: Fed4FIRE+ is the largest federation worldwide of NGI testbeds, which provides open, accessible and reliable facilities supporting a variety of different research and innovation communities and initiatives in Europe.

The major objective of this Call is to make Fed4FIRE+’s federated infrastructure directly available for execution of innovative experiments by experimenters at both industrial (including SMEs) and research organisations. Examples of such experiments may include but are not limited to testing of new protocols or algorithms, performance measurements or scalability testing. These Calls envisage experiments by which existing products or services are tested, implemented or optimized on the Fed4FIRE+ testbeds rather than proposing or developing new ideas from scratch.

Target participants: Proposals will only be accepted from a single party eligible for participation in EC H2020-projects (no consortia are allowed).

NGI ASSURE 4th Open Call

Opening date: 1 June 2021, 12:00 PM CET (Brussels time) (next 1 August 2021)

Closing date: 1 August 2021, 12:00 PM CET (Brussels time) (next 1 October 2021)

Short description: TThe goal of NGI Assure is to support projects that design and engineer reusable building blocks for the Next Generation Internet as part of a complete, strong chain of assurances for all stakeholders regarding the source and integrity of identities, identifiers, data, cyberphysical systems, service components and processes. Furthermore contributions can be made to address underlying real-world challenges in deploying and validating such building blocks, such as energy efficiency and sustainability, scalability and throughput, security, privacy/confidentiality, plausible deniability, robustness and crypto-agility, side-channel resistance, interoperability, governance and compliance to regulatory frameworks – where
needed to turn the above into reproducible and trustworthy end-to-end solutions that can withstand the hostile battle grounds of the modern internet.

We are looking for projects that have research and development as primary objective and that commit to generate open knowledge and open source building blocks relevant to developers, operators and users across all kinds of public and private application domains that have standardization potential.

Target participants: Anyone that can bring a relevant contribution to the topics of NGI Assure can apply, whether you are a natural person or an organisation of any type that wants to improve and further
develop Distributed Ledger Technologies, advanced blockchain technologies and related enabling technologies.

NGI Zero Discovery 16th call

Opening date: 1 June 2021 (next 1 August 2021)

Closing date: 1 August 2021 (next 1 October 2021)

Short description: NGI Zero Discovery will support new ideas and core technologies improving search and discovery. We are seeking project proposals between € 5.000 and € 50.000 – with the potential to scale them up if there is proven potential. Search and discovery are basic human needs for humans of all ages, and we would like to put powerful new technology in the hands of future generations as building blocks for a fair and democratic society and an open economy that benefits all.

Target participants: Projects are judged on their technical merits, strategic relevance to the Next Generation Internet and overall value for money. The key objective is to deliver potential break-through contributions to the open internet. All scientific outcomes must be published as open access, and any software and software must be published under a recognised open source license in its entirety. More information on eligibility:
