Thanks to extensive research and close monitoring of international efforts, we’re planning our route towards distributing cleaner, more energy efficient renewable gas including green hydrogen, biogas and bioLPG.
Gas is changing
Clarus believes renewable gas has a big part to play in New Zealand’s energy future and we're right behind it.
At Clarus, we want New Zealanders to continue enjoying the benefits of gas while keeping New Zealand clean and green.
Biogas
Food waste accounts for a large portion of global greenhouse gas emissions. When we discard food waste through unsustainable methods, we also compromise our water resources, intensify pollution, accelerate soil erosion, and threaten biodiversity.
Anaerobic digestion provides a sustainable solution for diverting food waste from landfills. In doing so, methane emissions are reduced, and soil health is restored.
Working towards a Net Zero Emissions by 2050
Working towards a Net Zero Emissions by 2050
At Clarus we are 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.
The future of bioLPG
BioLPG is chemically identical to Liquefied Petroleum Gas (LPG), but with a lower carbon footprint.
Liquified petroleum gas, or LPG, is used in thousands of homes and businesses across New Zealand and particularly in the South Island. Many homes use 45kg LPG bottles to fuel their gas fires and hot water cylinders – providing instant heat all year round- as well as 9kg bottles to fuel the barbie.
New Zealand uses around 185,000 tonnes of LPG annually. While LPG is only meeting a tiny fraction of our total energy requirements and emits much less carbon dioxide than other fossil fuels, it still contributes to our national greenhouse gas emissions. By switching to bioLPG (also known as renewable LPG or rLPG) we can reduce our emissions which helps New Zealand transition to a future with net zero carbon emissions.
The development of bioLPG is an exciting area for research and development, and one that Clarus continues to support. As a member of GasNZ, Clarus is supporting studies into bioLPG across the industry. We’re also looking into bioLPG as an alternative low carbon product for our customers.
We’re planning NZ’s first Hydrogen blend trial
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.
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.

Big oil moves into biogas
Big oil companies aren’t in the business of losing money. That’s why it’s fascinating to see Shell and BP investing billions of dollars into biogas, a renewable energy source that could eventually replace natural gas and help reduce global carbon emissions.
