The conversation on climate change and decarbonisation is heating up in New Zealand and around the world. Some are wondering if there is a future for gas in New Zealand. We say yes.

100% renewable energy is an aspirational goal. When you look at the big picture, we believe a balanced approach to our energy mix is needed. Ultimately, we want Kiwis to feel confident in choosing gas for their home and confident they are contributing to a cleaner, greener Aotearoa.

 We share our vision for future energy in tomorrow's home

Gas is part of a sustainable NZ

Natural gas and future gases have a role in ensuring NZ has a reliable, affordable and resilient energy supply as we move to a low-emissions economy.

Natural gas is the cleanest burning fossil fuel, with CO2 emissions at less than half those of coal. Exciting new technologies are helping us move to even cleaner alternatives, when used along side natural gas, they could reduce net carbon emissions to near zero levels. 
We are exploring if zero carbon emission options like hydrogen gas, which may be delivered through our existing pipelines; along with biogas, which is generated from converting decomposing organic material like landfill or agricultural and forestry waste. Carbon capture and storage (CCS), captures CO2 emissions from natural gas to stop them from entering the atmosphere. 
Innovative technologies are all part of our transition to a lower carbon future and a sustainable energy choices.

NZ has plenty of natural gas

There’s plenty of natural gas available to power Kiwi homes and businesses well into the future. 

Residential homes directly use only a very small amount of all the natural gas produced in New Zealand – less than 3.6%. The rest is used by business and industry, and you may be surprised to learn around one-third of natural gas is used to generate electricity – some of which you’ll use in your home. There is plenty of natural gas energy available to supply our residential homes, for decades to come.

With around 15 producing gas fields and 31 active exploration permits across New Zealand, we’re confident that the gas you use to power your heating, hot water and cooking appliances isn’t running out anytime soon.

Kiwi homes use only 3.6% of NZ's natural gas

Almost all the natural gas produced in NZ is used by business and industry and to generate electricity too! 

Many industries like the petrochemical industry to make methanol and fertilisers, industrial heat processing including paper and pulp mills, and food and processing plants, including dairy; deliver significant economic benefits to New Zealand. They either need a reliable energy supply or to use natural gas in its raw form for processing. Using natural gas directly in your home - not indirectly through electricity generated using natural gas - you’re helping to ease some of the increasing demand on electricity and contributing to a more sustainable future.

1% of NZ's total greenhouse gas emissions

Collectively Kiwis use of natural gas to directly power the heating, hot water and cooking in their homes produces less than 1% of New Zealand’s total greenhouse gas emissions.  

There are around 270,000 households and businesses enjoying the benefits of natural gas piped directly into their homes, contributing less than 1% of New Zealand’s total greenhouse gas emissions. In other parts of the world, less advanced in their journey to using renewable energies, natural gas is also helping to reduce emissions by replacing coal in the generation of electricity or as a direct energy source. With the potential for emerging technologies like hydrogen, and biofuels to decarbonise gas, the level of emissions could reduce even more on New Zealand’s path to a net zero carbon emission future.

Natural gas is used to generate electricity

It might be surprising, but when we don’t have enough electricity from renewables to meet demand. 

Everyone agrees that renewable energies are great for the planet. Today, around 80% of NZ’s electricity is generated from renewables – mostly water and geothermal. At peak times, like winter, or when lake or wind levels are low, we can’t generate enough to keep up with demand. Renewable electricity can’t easily be stored, so when it’s generated, it is a ‘use it or lose it’ situation. To meet the shortfall, natural gas or coal is used to generate electricity.

The case for 100% renewable energy isn’t clear-cut. The infrastructure and investment needed to provide enough renewable electricity to meet peak demand is significant, and at times of regular demand, it would be wasted. For NZ to achieve 100% renewable energy, the amount electricity generation required would be double in order to meet the demand. The impact for Kiwi households could be an additional $225 per month [1].

A balanced approach seems best - switching to greener energy options where it is practical and affordable. 

Retaining options for better outcomes

Energy in NZ is a delicate balance between affordability, reliability and environmental sustainability. 

Like many things in life, when it comes to our energy system, a balanced approach makes good sense. Too much focus on any one of the three key things means over compromising on the others. Generating 100% renewable energy requires a huge investment and would significantly increase energy costs to consumers. To be fully renewable, while also being affordable, risks not having enough electricity to meet demand at peak times.

The key is balance, and natural gas has an important role to play in helping reduce overall demand for electricity and keeping energy affordable for everyday Kiwis. Emerging energy technologies will also reduce, or even eliminate, net carbon emissions and provide alternative clean energy gas sources.

The beauty of energising your home with gas is that you can connect one system now and easily retrofit others in later.  Gas is ready to transform as we move towards a carbon-zero future. It really is the ultimate, affordable, comfort upgrade for your family. Take your home into the future and enjoy better living.
