While troubleshooting gas appliances can be complicated, new diagnostic computer systems, electronic controls and remote monitoring capabilities make the process much easier. Therefore, enlist the help of qualified professionals without delay when needed.
There is a major global push to transition from fossil fuel-derived natural gas towards renewable alternatives like green hydrogen or biomethane.
Hydrogen natural gas can be produced through electrolysis, a cycle air process powered by renewable energy sources.
The gas utilities sector is already taking proactive steps to enable this transition. Modern gas stoves, hot water heaters and space heaters are designed and certified to be compatible with hydrogen blends and bio-methane. Some models can operate on 100 renewable gas without any modifications.
For consumers in an existing home, transitioning gas systems to renewable fuels may require upgrades like nozzle adjustments and control system recalibrations. Professional technicians can manage this seamlessly. The costs for this transition are competitive with, or slightly higher than, those of traditional natural gas.
As energy networks gradually integrate renewables like green hydrogen into their pipelines, homes and businesses will be able to effortlessly switch over to sustainable energy for gas appliances. This supports emissions reductions targets as well as provides longevity to gas infrastructure investments.
Hydrogen has enormous potential as a renewable gas alternative which can significantly reduce emissions. When used in fuel cells or burned for energy, Unlike fossil fuels, hydrogen combustion only yields water vapour, not greenhouse gases.
Current pioneering initiatives are exploring the integration of hydrogen into existing Australian gas networks. Trials by Australian Gas Infrastructure Group and Australian Gas Networks aim to establish the feasibility of eventually transitioning to 100% renewable hydrogen gas.
Utilising hydrogen has the potential to render gas appliances nearly emission-free, yet maintaining instant heating and recognised functionality within a connected gas infrastructure. For consumers, the switch would be invisible, with existing pipes and appliances remaining compatible.
However, Green hydrogen production hinges upon a plentiful supply of renewable electricity. Expanding solar and wind capacity is key to making hydrogen an economically and environmentally sound fuel option. We need supportive policies that will be vital to scale up hydrogen and make the transition affordable.
As renewable energy costs decrease and government investments target this area, a hydrogen-powered future for residential and industrial sectors might be on the horizon sooner than expected.
Biomethane, also known as renewable natural gas, is a sustainable alternative produced from organic waste materials. As bacteria breaks down waste in an anaerobic digester, Biomethane is harvested and refined to match conventional natural gas in quality.
Biomethane, once stored existing, can be directly injected into gas networks without any modifications required. Gas appliances running on biomethane provide the same instant heating and functionality while reducing emissions by up to 125kg CO2-e per MWh - eliminating the need to fully electrify systems.
Other leading renewable gas options include synthetic methane produced through combining renewable hydrogen with carbon dioxide, or upgrading landfill gas capture systems into higher purity fuels. Such alternatives are projected to supply much more than 10% of eastern Australia’s annual gas needs by 2040.
Renewable gases like biomethane allow households and businesses to reduce their carbon footprint while retaining the convenience of gas appliances. As production scales up locally, they will become more cost competitive with fossil fuel gas, further accelerating adoption.
An accelerating shift worldwide from gas appliances to electrification, powered by renewable energy, is underway.
