Deliverables

Documents, reports (7)

Management Guidelines

The Management Guidelines set out the project’s rules and structure, and summarize the partner’s re-sponsibilities according to the Grant Agreement

Definition of testing protocols

definition of the detailed testing phases, fingerprint, short term release and long-term testing, to allow comparison of the different stack technologies considered in the benchmark

Report on CO2 emission avoidance for chemical industry

Evaluation of the benefit of replacing fossil hydrogen by renewable hydrogen produced by HTE and extrapolation impact on the whole EU chemical industry sector

Dissemination and Communication Action Plan (update)

Updated document with follow up and review of the initial planning and actions reviewed target audiences and appropriate channels and tools announcement of major planned and upcoming events linked to dissemination

Long-term testing report

reporting and comparing the long-term testing results, and identification of opportunities offered by the most promising technologies for subsequent upscaling

Assessment of hydrogen certification while using waste-heat and steam from industrial applications

The assessment includes the existing green hydrogen certification as defined within the CertifHy project Phase 2 and analyses possibilities and methodologies to apply this on an integrated HTE utilizing steam and heat sources from industry The investigation will reveal if and how the CertifHy methodology can be applied for integrated HTE systems and identifies barriers for potential market penetration in order to derive suggestions for decision makers

Dissemination and Communication Action Plan

Presentation of the strategy (including targets and tools, and budgeted actions) and planning and re-view of the main communication and dissemination events.
