The hydrogen blended gas must be approved by the Health & Safety Executive to be ‘as safe as natural gas’ for any potentially affected party. This means the blended gas should not pose a greater risk to buildings on or close to the live trial area than the normal gas supply.
Is there additional danger for buildings which are close to the trial area?
Safety
