The future of gas is changing and we're right behind it

Gas is changing

New Zealand's gas is heading in the right direction

As Kiwis, we love the benefits gas brings. Summer barbies, instant heat, endless hot water, and cooking with a flame. But we also love our clean, green environment – and we want to see New Zealand reach its goal of zero carbon by 2050.

So, can we have both? We think so. But it means we all need to make some changes.

At Firstgas Group, we’re 100% behind Aotearoa’s zero carbon future.

The gas used in Kiwi homes currently makes up less than 1% of the country’s total greenhouse gas emissions, while commercial and industrial gas users contribute 8%. It’s not much – but we think we can do better!

We’ve been investigating cleaner, low carbon gas options.

Natural gas and LPG are cleaner burning fuels, with lower CO2 emissions than coal or wood burners. But (along with the rest of New Zealand’s energy sector) we need to go a step further[1].

That’s why we’ve spent two years investigating the possibilities of low carbon gas–primarily hydrogen, biogas and bioLPG – some of which are already being tested in New Zealand and are well-advanced overseas.

With these potentially low carbon gas alternatives, we’ll be able to continue using our existing pipeline networks and distribution channels to distribute gas. It’s a pretty good way for us to help reach New Zealand’s zero carbon goal by 2050, while still enjoying a good ol’ fashioned Summer barbie.

Our goal? To help New Zealand be zero carbon 2050.

With the support of the government, we’re already looking at how we can use our existing gas pipelines to carry renewable gas to New Zealand homes and businesses, including leading part of a Hydrogen Pipeline Trial and being involved in a Biogas Industry Study. We’re also closely following the results of extensive hydrogen research and development in Australia and Europe – where some gas networks are already successfully blending up to 20% hydrogen.

As part of the World Energy Council’s Global Hydrogen Initiative, we’ve started planning to introduce hydrogen into our existing gas networks from 2030 – gradually increasing from 1% to 20% hydrogen by 2035. Our research shows that we can convert the Firstgas pipeline network to 100% hydrogen by 2050. This step would reduce New Zealand’s energy emissions by nearly 25%.

Already using natural gas or LPG in your home or business?

Most appliances will work on up to a 20% blend of hydrogen, and our network is already set up to deliver this. So, while we help change the future of gas to meet New Zealand’s zero carbon goal, you can continue enjoying the benefits of gas.

Firstgas Group target is delivering 20% blended hydrogen by 2035 with 100% by 2050

We’ve investigated what New Zealand’s hydrogen future could look like and how our network can play its part.

In 2019, Firstgas received $260,000 in government funding managed by the Provincial Development Unit to investigate how existing gas infrastructure could adapt to transporting hydrogen. The first phase of the work programme was a hydrogen pipeline trial study to investigate the role of hydrogen in decarbonisation and what we will need to do for our network to carry hydrogen.

This Hydrogen Pipeline Trial Study shows we have sufficient network capacity and a viable strategy for converting the networks to hydrogen blends and then 100% hydrogen. Our study findings confirm that our network could be delivering a blend of 20% hydrogen by 2035, with a move to 100% hydrogen by 2050. This would be supported by large scale storage of hydrogen in Taranaki to provide inter-seasonal and inter-year flexibility for the energy system.

Hydrogen can reduce Aotearoa's energy sector emissions by up to 25%.

Hydrogen is a cleaner alternative to natural gas. It can be produced by electrolysis, which is the process of using electricity to split water into hydrogen and oxygen. If the electricity is generated using renewable resources, like wind and solar, then the process creates no new carbon emissions, and the hydrogen produced is “green” hydrogen.

Based on our study, hydrogen could replace natural gas demand in most sectors by 2050. Hydrogen has the potential to displace a range of different fossil fuels currently used for high-temperature process heat, building heating, electricity generation and large-scale energy storage which goes a long way to supporting a 100% renewable electricity system.

Gas is getting even better

What do you need to do?

We’re right behind changing the future of gas to help reach New Zealand’s zero carbon goal by 2050. So while we continue working in the background, you are able to continue enjoying the benefits of gas.

Our path to low carbon gas

Graphic BBQ Clearcut

We believe gas has a big part to play in New Zealand’s energy future. Thanks to extensive research and close monitoring of international efforts, we’re heading in the right direction towards cleaner, more energy efficient gas – and to ultimately helping New Zealand reach its zero carbon goal by 2050.

The future of kerbside waste is changing too

We’re working on New Zealand’s first large-scale biogas project that will turn food scrap waste into biomethane, a valuable source of renewable gas for homes and businesses. Action that helps move New Zealand towards its target of net zero carbon emissions by 2050.

For Firstgas Group, the Hydrogen Pipeline Trial Study set the foundation for our ongoing delivery work on hydrogen. The results show we have sufficient network capacity and a viable strategy for converting our pipeline networks to a 20% hydrogen blend from 2030 and moving to 100% hydrogen by 2050.

Natural gas has been a reliable, efficient and affordable energy source for Kiwis for over 50 years[2][3]  – and we believe it has a crucial role to play in New Zealand’s journey to zero carbon emissions by 2050.
