Project

Challenges addressed

HFC technology will first be commercialised for applications where it is market-ready due to superior value and/or comparative competitiveness: backup power supply, portable power generation, powering of materials handling vehicles, etc. These early markets are also strategically important to build up and sustain a manufacturing and supply base for longer term applications.

These applications involving the commercial use of hydrogen as an energy carrier imply very different environments from the existing, mostly industrial, applications. The new applications generally require, by nature or for security reasons, that hydrogen systems be used indoors. Yet existing Regulations, Codes and Standards are very incomplete regarding the practical specification of safety requirements indoors.

Hyindoor addresses the issue of safe indoor use of HFC systems for early markets: it aims to provide scientific and engineering knowledge for the specification of cost-effective means to control hazards, and to develop state-of-the-art guidelines.

Technical approach

The aim of the work is to develop the capability to specify practical means and strategies that will prevent or mitigate the potential consequences of a hydrogen release indoors. This will be implemented with a risk-based approach: the higher the expected frequency of the release, the more stringent the acceptance criteria.

The Hyindoor programme is split into technical 7 work packages

Socio and economic impact

HFC technology is expected to constitute a major contribution for environmental protection and rational use of energy. However, hydrogen as an energy carrier requires a sound safety framework of harmonized RCS to reach commercialisation.

The generated knowledge will feed into safety guidelines. The experimental work will significantly enhance our understanding of hydrogen dispersion and combustion; the increased predictive ability of CFD modelling will enable its applicability to particular settings without experimental information — particularly useful given the variety of potential applications.

Recommendations for normative / regulatory requirements are expected to lead to the adoption of the results by the wider stakeholder community, and their introduction into RCS. A unique initiative, this can give Europe a leading position.

The benefits of optimised design and RCS upgrade are expected to significantly improve the prospects of hydrogen as an energy carrier. Additionally, the IP developed in HyIndoor will benefit European industry and research.
