Renewable gas and lower emission solutions are critical for enabling the global transition towards a sustainable energy system. Options like renewable natural gas, hydrogen and carbon capture provide cleaner alternatives.
Natural gas is a cornerstone of Australia’s energy landscape, delivering consistent and reliable power to homes and businesses. However, the combustion of gas emits greenhouse gases, which contribute to climate change and raise concerns about environmental sustainability. It’s crucial we adopt renewable energy sources to protect our planet and secure a sustainable future.
At Strathfield Plumbing, we recognise the immediacy of reducing our carbon footprint while maintaining service reliability with sustainable practices. We strive to lead the plumbing sector in Sydney in achieving lower carbon emissions, committed to meeting our targets promptly by providing efficient, low-emission plumbing and gas solutions.
This article explores renewable gas innovations, the rise of technologies such as renewable hydrogen and biomethane, and strategies for adopting more eco-friendly gas practices in line with net-zero emission targets.
There are several renewable gas alternatives that can provide carbon neutral solutions for replacing natural gas usage:
Biogas, produced from organic waste and capturing methane, presents a renewable option for reducing greenhouse gas emissions.
Sources for sustainable biogas production, such as landfills, wastewater plants, farms, and food waste, enable its use as a natural gas substitute. Biomethane, a purified form of biogas, integrates smoothly into our pipelines, fostering more sustainable energy practices. Through renewable gas technologies such as integrating biomethane, we aim to significantly slash carbon emissions and achieve net-zero by 2040.
Hydrogen, which yields only water vapour upon combustion, can be generated from renewable electricity and seamlessly merged into our current pipeline systems. International Energy Agency scenarios suggest that renewable hydrogen could be a foundational energy source by 2050.
Hydrogen Park South Australia has successfully trialled a 5% hydrogen blend, illustrating the potential for utilising hydrogen in our gas networks. Leveraging our inventive strategies, we can use our extensive expertise to generate lower carbon solutions and incorporate them into existing gas networks, advancing and achieving our goals of transitioning towards innovative gas energy solutions and significant decarbonisation.
Synthetic natural gas (SNG) is chemically akin to natural gas, allowing us to utilise our existing infrastructure for energy storage and consumption, integrating easily within our distribution networks. SNG, which can use our existing infrastructure in the same way as natural renewable gas, is generated by fusing hydrogen from electrolysis with carbon dioxide retrieved from industrial emissions or directly from the atmosphere, simplifying the continued use of gas appliances with reduced carbon effects.
These future gas alternatives offer the strategic innovations we need to create a lower carbon future, play key roles in diversifying the energy mix and permit homes businesses to maintain their autonomy in choosing energy solutions while upholding sustainability ideals. Strathfield’s endeavour towards our 2040 goal of no residual carbon emissions in our gas network could hasten carbon neutrality, especially with increased production of renewable gas.
Technological advancements have demonstrated that sustainable gases can make reliance on gas a more efficient and low-emission transition energy source.
Blending energy sources like biogas and hydrogen into our extensive existing distribution networks illustrates this potential. Innovations in injection and monitoring technologies empower our gas systems to accommodate a wider range of energy sources, with the potential to surpass the current 5% renewable mixes.
Environmentally conscious companies such as Eneraque have developed modular biogas solutions that convert waste sources into injectable biomethane for the grid. This distributed approach, which we need, is central to renewable gas projects, aids the circular economy by reducing methane emissions from waste, thereby achieving our aim to maintain access to sustainable energy, an aspect we can use our expertise on.
Projections from a Western Australian study indicate that by 2030, our networks could handle significant gas volumes, including a 10% hydrogen blend, potentially reaching over 60% by 2050. The shift towards renewable hydrogen production, leveraging clean energy from sources like wind and solar power, would substantially reduce emissions from gas consumption.
Innovations such as methane detection systems and zero-leak pipes minimize emissions during gas distribution. Collectively, energy technology is spearheading the merging of new gas options at scale to reduce emissions en route to net zero.
Transitioning from coal, oil, and other fossil fuels to renewable options poses several challenges:
There are currently higher infrastructure and production costs for most renewable gases compared to traditional natural gas. As technology advances and production scales, costs are expected to decrease, facilitating a more sustainable future. Government incentives and innovations can help accelerate the journey to cost parity for consumers.
Renewable gas can indeed be amalgamated; however, this requires improvements within the gas sector, specifically in distribution systems including pipelines and end-use appliances. Nonetheless, examples like the Hydrogen Park experiment validate that the gas sector can securely manage blends currently and are forging ahead towards assimilating renewable energy sources at the same time, progressing to renewable gas we can be ready for by 2050.
Current gas quality standards present obstacles for renewable blends, but continuing advancements are paving the way for integration. But regulators are conducting feasibility studies to support updating gas specifications. This progression will allow networks to channel increasing volumes of renewable gas, aligning with emission reduction mandates.
With renewable production ramping up globally, with almost half the battle won through infrastructure commitment and regulatory revision, these hurdles can be overcome. Strathfield can lead the transition towards sustainable gases, preserving their choice of energy for residences and enterprises, and achieve the target being net zero emissions on the gas network, with a stretch goal achievable by 2050.
Homeowners and businesses can implement various measures daily to increase the sustainability of their gas consumption:
An energy audit can uncover ways to boost energy efficiency and monitor usage more effectively, offering actionable insights directly to your email. Expert examinations by our much more experienced team of technicians at Strathfield Plumbing, after a thorough review of your energy needs and email address, can lead to evaluations of home or commercial energy systems, allowing for dynamic troubleshooting, retrofitting to reduce waste, and recommendations to switch to renewable gas when practicable.
Replacing old gas appliances like boilers, heaters and stoves with new energy-efficient models can reduce gas usage and utility bills. Look for ENERGY STAR rated appliances with smart controls that optimise performance.
Properly insulating walls, floors, attics and sealing gaps around windows/doors ensures heat stays inside, lowering gas heating requirements in winter.
Leveraging industry expertise through an audit and implementing efficiency upgrades paves the way towards more sustainable gas consumption aligned with net zero emissions goals.
In the battle against the potential GWP (Global Warming Potential) of fossil fuels, transitioning to sustainable gas solutions like renewable hydrogen and biomethane provides significant economic, environmental and social benefits compared to continued fossil fuel usage:
Local renewable gas production and strategic development ensure sustainability while keeping energy affordable and accessible within our existing infrastructure. With industry commitments and a collaborative approach, Strathfield can power data centers and other establishments through greener gas usage, bringing broad economic, environmental and social benefits.
On gas work sites, required safety gear usually includes eye protection, hearing protection, hand and foot protection, and flame-resistant clothing to protect against hazards. Proper protective equipment is essential to avoid injuries when working with flammable gases.
