You might think it's splitting hairs, but there's an important distinction here. The pyrolysis of natural gas (as is intended for the Canadian plant) to produce hydrogen, is classified as "turquoise hydrogen" because natural gas from fossil fuel can contain up to around 30% CO2 and the fugitive emissions are considerable. Using pyrolysis of methane derived from biogas removes carbon that's already in the system, thereby essentially removing carbon from the atmosphere. This was the key reason Hazer have designed the CDP to use the methane from the water treatment plant and what makes the Hazer process "carbon negative", theoretically even better than green hydrogen via the electrolysis of water.

Having the facility to produce hydrogen from either natural gas or methane from the water treatment plant would be an ideal demonstration of the versatility of the Hazer process.
The comment on LinkedIn is just that, a comment, it was not an announcement. We don't know who who wrote it, so its accuracy cannot be relied on like a company announcement to the market. So its clarification is still required.
