Safety is Critical For Public Acceptance Safety is critical to protect “nascent technologies at a critical time in their emergence into the wider consciousness” (Gammon, 2004) “ …we don’t know much about it at all, other than we used to make bombs out of this stuff.” -Local Hornchurch resident, Mike Dyer Romford Recorder May 2003. “My feelings are rather strong on this, I think it must be dangerous.” -Local Hornchurch resident, Stephen Kelly, Romford Recorder May Practical Implementation of Renewable Hydrogen & Fuel Cell Installations in the Built Environment Gavin D.

PURE Energy Centre, Baltasound, Unst •The PURE Energy Centre is a venture on the northernost Shetland Island of Unst. Established originally as a community venture, the project has since grown into a world-leading consultancy on clean hydrogen. •Island community •Highest Oil Prices in UK •‘Energy Isolation’ – North Sea Oil currently generates revenue. •Lack of “highly skilled” jobs •Problems retaining young people on the island Two Proven Wind Turbines Produce Renewable Power This feeds an electrolyser which produces hydrogen. This hydrogen can be stored, for later use. An onsite hydrogen fuel cell provides heat and power. A small fuel cell vehicle can be refuelled using H2

There is not yet a standard for hydrogen installations in the same way that there is the GasSafe (Formerly CORGI) quality mark for domestic and commercial gas installations. The United Kingdom Hydrogen Association is working to address this. Present guidance is taken from the statutory industrial regulations listed below and manufacturers standards, and projects are assessed on a case-by-case basis, this adds significant expense to hydrogen installations due to the extra work of performing due-diligence.
Need to move towards a standard that can

Companies such as BOC have a long experience of working safely with Hydrogen as an industrial gas. HAZOP Analysis – Hazard and operability studies; are a useful tool in refining process and procedure to ensure safe-working practise. Also consider: Strong alkali which is used in electrolyser systems, its storage and use should be done in accordance with the COSHH regulations. •ATEX (Explosive Atmospheres) Practical Implementation of Renewable Hydrogen & Fuel Cell Installations in the Built Environment Gavin•D.

Points to Note • Individual components work well… “Systems Integration” is the challenge for services engineers. • “Packaged” solutions may be an easy route to turn-key adoption (off-site fabrication) • More space for servicing may need to be allowed whilst hydrogen technologies are developing. • In common with other CHP, size fuel cell to maximum heat demand.

Points to Note • Sub 100kW Fuel Cells Accommodated in 19” Racks. • High temperature systems in excess of 200kW will fill a 20’ container with auxiliary devices, safety systems and balance of plant. • Clearance at front and rear for access. • Consider siting: – Electrical cables flowing to and from the fuel cell. – Hydrogen supply pipework supplying the fuel cell. – An exhaust pipe which will be large diameter and take a similar form to a gas boiler flue. – A waste water drain for the exhaust water from

Points to Note • Dry hydrogen through pipes can build up static charge (equipotential bonding as with gas) • Consider careful siting of flue to prevent creating an “ATEX Zone” remove sources of ignition. • Waste water (very clean can be recycled) • Fuel cell outputs D.C. power.
