Have your say on adoption of 13 international hydrogen-related equipment safety standards

We invite you to review 13 draft international hydrogen-related standards proposed for adoption.

In 2023 we released the Hydrogen standards review report, a thorough review of technical standards governing the production, distribution, and utilisation of hydrogen that might enable the safe integration of hydrogen across New Zealand’s energy landscape.

Hydrogen standards review report

The review led to a recommendation to directly adopt relevant international standards that would allow New Zealand to draw upon international good practice and tried and tested solutions. This represented an economical and efficient way to pave the path for hydrogen integration and safety.

Now, we invite you to review the 13 draft international hydrogen-related standards proposed for adoption. Hydrogen integration impacts many industries – from those working with storage facilities, to transport and decentralised distribution and piping – we encourage you to have your say on how these would work for you and your industry.

The committee have reviewed the standards and will consider all feedback to ensure the adoptions are fit for the New Zealand energy landscape.

Why hydrogen

Hydrogen adoption is part of New Zealand’s largest energy transition in more than 100 years. The government has a legislated target of net zero greenhouse gas (GHG) emissions – other than from biogenic methane – by 2050, and a target under the Paris Agreement to reduce net GHG emissions to 50% below gross 2005 levels by 2030.

Considerable renewable energy resources exist that could be harnessed to sustainably produced hydrogen as a next-generation green fuel source, and industrial feedstock.

This project forms a part of a greater concerted effort by multiple organisations leading the way in hydrogen use – you can learn more about other projects on the Hydrogen New Zealand website:
