Hawaii Gas is the sole gas utility in Hawaii and reports its own safety data. There's no independent monitoring body doing spot checks on their leak rates.
Same situation. No independent oversight.

Do you have access to a digital device? Good start.
Next step is to use something called a search engine. Google will work.

I'll tell you one thing hydrogen has been found to be. Expensive.
Do you like it when expensive things leak?

wait - so you're getting something of value from it? It appears to me that you are a wind dev consultant and my site is giving you insight for free? If I could provide some premium features, would you pay?

National Transmission System hydrogen blending: study
The project sets out analysis on the potential impacts of hydrogen blending in the national transmission system (NTS) at blend percentages of up to 2%, 5% and 20%.

Why?
Hydrogen has 1/3 the energy density of natural gas. Sites reported reduced power output, 2-6 year modification lead times, combustion instabilities, safety concerns from embrittlement/leakage, and increased NOx emissions.

This "breakthrough" appears to use a brand new hydrogen-specific turbine installed last year - not existing infrastructure.
A govt-commissioned Arup survey of existing UK gas stations tells a different story: Almost all reported significant challenges accepting blended hydrogen:
