The H21 NIC will be delivered in 2020, followed by field trials. Phase One of the NIC project is being carried out in two parts:
Phase 1a – Background testing at the Health and Safety Laboratories, Buxton. These tests, on a huge variety of network assets including pipes, valves and joints, will confirm potential changes in background leakage levels.
Phase 1b – Consequence testing at the DNV-GL facility at RAF Spadeadam in Cumbria. This phase will involve tests to confirm any changes to safety risk under background conditions, failure and operational repair on a hydrogen gas network.
Following on from the evidence found in Phase 1a and 1b the project will move forward into Phase 2. Phase 2 will involve testing of operational procedures.
To enable the field trials to commence once Phase 1 is completed the project has secured Network Innovation Allowance funding to locate suitable test sites and develop the conceptual design, now underway. In line with BEIS’ Hy4Heat project, once the field trials have proven that it is safe to move forward there will be a live trial in 2021/2022.
