Greenhouse Gases (GHG) Fugitive Emissions

GHG Monitoring

The principal supplier of water, wastewater & drainage servicing to over 2 million people throughout Australia, awarded AquaGas Pty Ltd for the supply of 2 SmartCEMS GHG for their wastewater treatment facilities.

Broadly, wastewater systems contribute to GHG emissions not only through their significant consumption of grid electricity in most cases, but also through direct emissions of nitrous oxide (N2O) and methane (CH4). These are often called ‘fugitive’ gases because they escape from the collection and treatment systems.

For this project AquaGas scope includes the provision, installation, and commissioning of 2 stand alone monitoring systems designed to monitor continuously and simultaneously N2O, CH4, CO2 and O2. Equipped with multistream sampling system, these analysers are used to check multiple sources across a wide range of locations in the client’s production facilities.

AquaGas online analysers are suited to a large range of applications related to Greenhouse Gas fugitive emissions such as emissions and process monitoring at

  • WTP Ponds (with sampling hood)
  • OCS odour control systems (inlet & discharge)
  • Biogas plants (digesters, engine feed, engine emissions…)
  • And Landfills (fenceline, landfill gas…)

When used to their full extent, the expanded capabilities offered by accurate and reliable analysers can bring real benefits by providing fast access to detailed GHG emissions data and an accurate real time overview of operating conditions at urban utilities and industrial sites.

SmartCEMS® GHG

GHG emissions from wastewater handling

Broadly, wastewater systems contribute to Greenhouses gases (GHG) emissions not only through their significant consumption of grid electricity in most cases, but also through direct emissions of nitrous oxide (N2O) and methane (CH4). These are often called ‘fugitive’ gases because they escape from the collection and treatment systems.

CH4 emission: Wastewater contains organics, which can be biologically converted to CH4 in the absence of oxygen (i.e., under anaerobic conditions). In some parts of wastewater collection and treatment systems, anaerobic conditions prevail, leading to the formation of CH4 and its subsequent emission into the atmosphere.

N2O emission: Wastewater contains nitrogen, which needs to be removed to avoid nutrient enrichment of receiving waters. Biological nitrogen removal has been implemented at most large wastewater treatment plants in Australia. N2O is either an intermediate reaction or a by-product of the key biological reactions involved. Therefore, N2O is formed in, and could be emitted from, wastewater treatment plants.

The indirect emissions are expected to decrease substantially in the coming decade, due to both the increased recovery of energy from wastewater (biogas from anaerobic digestion) and improved efficiency of electrical energy use for wastewater treatment.

Furthermore, the current trend is towards increasing renewable energy supply, with resultant lower emission factors. Therefore, it is foreseeable that direct emissions might in future dominate the GHG profile of many wastewater treatment plants. Indeed, for some treatment plant in Australia, this may already be true.

Actual methane and nitrous oxide emissions associated with wastewater handling vary significantly, depending on the type of system and a range of operating factors.

Emissions can make up a substantial portion of direct GHG emissions reported as part of the total for water utilities that serve urban areas. The existing GHG reporting (NGER) system in Australia does not make provision for measurements or estimates of actual direct emissions of nitrous oxide and methane emissions from wastewater handling.

Understanding of greenhouse gas emissions related to wastewater handling has improved a lot in the last ten years, thanks to the efforts of researchers and the water industry, including significant contributions from Australia.

Committed to a better environment, AquaGas Pty Ltd is proud to supply and support a broad product range featuring a line of analysers tailored to the measurement of Greenhouse Gases emissions in the environment or directly at the source. Already selected by councils and water agencies, AquaGas analysers offer exclusive features implemented to fulfil the needs of today’s urban utilities and waste recycling facilities.

PROCEAS® in GH2 Plants

Process Control and Purity in GH2 Plants

The realization of the importance of shifting from fossil fuels, both for environmental and energy security reasons, makes the use of green hydrogen extremely pertinent, as one of several potential low-carbon fuels that could take the place of fossil hydrocarbons in GH2 Plants.

To maintain safe operation, optimise the power to hydrogen conversion, and maximize the quality and purity of the produced hydrogen; the green hydrogen production process relies on measuring multiple parameters as extensively as possible and using the resulting data to inform GH2 Plants Operators.

AquaGas online analysers are suited to a large range of applications within the GH2 Plants providing real time gas stream composition at key locations:

  • Upstream or downstream of the electrolyser
  • At mixing stations or injection points
  • Along the natural gas pipeline
  • At customer sites just upstream of burners

When used to their full extent, the expanded capabilities offered by accurate and reliable analysers can bring real benefits by optimising efficiency and safety, and providing fast access to detailed data and an accurate real time overview of the operating conditions.

Committed to a better environment, AquaGas Pty Ltd is proud to supply and support a broad product range featuring a line of analysers and gas detection systems tailored to the GH2 industry. Already selected by several of the main actors in the green hydrogen industry, AquaGas analysers offer exclusive features implemented to fullfil the needs of today’s Green Hydrogen production.

The ProCeas® multigas analyser for GH2 applications

For process control and purity assessment at GH2 Plants, the ProCeas® uses the patented OFCEAS technology, based on extractive absorption spectroscopy. This laser-based technology is able to measure gases down to sub-ppb levels of concentration, with an unforeseen quality of measurement in terms of accuracy and repeatability. The ProCeas® samples the gas at low pressure, with an internal pressure below 100 mbar absolute. This dilution reduces the volume needed to get a correct measurement and optimizes the response time of the analyser. In the end the system requires small samples of hydrogen.

Additionally, ProCeas® has an integrated auto calibration of the measurement system, allowing no drift under normal use of the instrument. ProCeas® can analyse a large range of impurities with limited service and maintenance costs.

The ProCeas® Hydrogen key features include:

  • Highly sensitive
  • Low detection level (sub-ppb)
  • Complete pre-calibrated laser infra-red spectrometer
  • No Zero drift and no Span drift – No daily calibration required
  • No nitrogen, zero air, purge or other carrier gas
  • ProCeas® H2 Purity for ISO compliance monitoring (H2S, CO, CO2, CH4, O2, NH3, H2O, HCHO, etc.)
  • Process control ProCeas® H2 trace analyser (H2 and O2)
  • Limited volume of sample needed for an analysis

The field of application for fast and precise online analysers in the GH2 Plants is considerably exhaustive. Here below are two cases where online measurement of H2 and O2 is critical.

The ProCeas® H2 trace gas analyser

Ensure safe Electrolyse with the ProCeas® H2

At their simplest level, electrolysers produce oxygen at the anode and hydrogen at the cathode. However, many reactions in the electrolyser can cause small concentrations of oxygen to build up in the hydrogen stream and hydrogen to build up in the oxygen. This is a fault condition and must be detected by appropriate instruments that can be used as part of an automated safety system that can initiate actions in the event of an oxy-fuel gas mixing alarm being activated.

With a detection limit down to 3ppm for the H2 and 1ppm for the O2, The ProCeas® hydrogen is perfectly suited to O2 and H2 trace gas monitoring and consequently can be used to measure both traces of hydrogen in the oxygen stream and traces of oxygen in the hydrogen stream.

The ProCeas® H2 Purity

Keeping production up to standard with the ProCeas® H2 Purity

As a multi-stage process, green hydrogen production requires accurate measurement of a variety of parameters to ensure safe and efficient operation. ISO14687-2 stipulates the impurities that need to be measured and their respective limits throughout the various stages of the production process to help maintain control and avoid potential issues that could affect efficiency or safety.

GREEN HYDROGEN [GH2]

Green hydrogen (GH2) is hydrogen that is  generated by renewable energy or from low-carbon power. One of the paths to near-total decarbonization is supplying the whole energy system using clean renewable power combined with low-carbon fuels. Hydrogen is an important component of global efforts around the world to de-carbonise the energy sector.

The realization of the importance of shifting from fossil fuels, both for environmental and energy security reasons, makes the use of green hydrogen extremely pertinent, as one of several potential low-carbon fuels that could take the place of fossil hydrocarbons.

The affordability of renewable energy resources as well as the developments in electrolysis technology increase the potential of “green hydrogen” as a clean and sustainable form of fuel production. The global hydrogen production is set to more than double in the decade between 2020 and 2030, from 70 million tons to 170 tons. Projections beyond 2030 point to a further increase as production technologies become more efficient and production costs fall.

GH2 is a versatile form of energy

Green hydrogen produced by the electrolysis of water may be used to decarbonize sectors which are hard to power from any energy other than fossil fuels, such as steel and cement production, and thus help to limit climate change.

Green hydrogen can be blended into existing natural gas pipelines, and used to produce green ammonia, the main constituent of fertilizer production. Green hydrogen can transform into many different types of energy, including electric and synthetic gas for heating, powering electronics, fuelling vehicles. Right now, the most common uses of green hydrogen energy are oil refining, steel manufacturing, ammonia production and food processing.

Hydrogen is abundant, it’s easier to store and provides a better efficiency than other energy sources.

Producing GH2

Key to the production of green hydrogen is the use of an electrolyser to split water into hydrogen and oxygen while renewable sources such as wind, solar or hydroelectric power generate the necessary power for the electrolysis process. Carrying out large scale electrolysis as needed to provide the quantities of hydrogen to overcome the growing energy demand presents several challenges.

It is obviously imperative that the entire production chain is monitored continuously for process control and safety. That includes maintaining optimal electrolyser performance, as well as avoiding potentially explosive leaks. Hydrogen affects the BTU value of the natural gas, therefore measuring the amount of hydrogen present in natural gas is critical for utility companies, industrials, pipeline distribution network, and of course the end user.

GH2 process monitoring and control

Plant performance, energy consumption, production rates, purity and storage are among the key performance indicators (KPI) for hydrogen production which require visibility to ensure efficient production.

To maintain safe operation, optimise the power to hydrogen conversion, and maximize the quality and purity of the produced hydrogen; the green hydrogen production process relies on measuring multiple parameters as extensively as possible and using the resulting data to inform Plant Operators.

Today’s online measurement technologies provide greater accuracy, range and depth of information that can be used to assess both process performance and the status of the plant, especially important in preventing unexpected problems such as faults or failures in safety-critical applications.

The MAMOS SmartCEMS® is an online monitoring system designed by MADUR and integrated by AquaGas for the ANZ market which responds to industrials and environmental authorities today’s demand for a large range of industrial applications including small to large combustion plants (power station, paper mill, cement plant…), WTE (waste to Energy) installations as well as biogas, syngas and biomass generators.

Thanks to its modular and adaptive design the Mamos allows combining multiple sensors (PID, low and high range NDIR, Electrochemical, Thermal Conductivity) with applications specific sampling systems (Direct extractive heated and standard sampling train, Peltier cooler, Nafion membrane…). All system components are field replaceable and comes with a 24 months warranty.

Available as standalone unit, single analyser or redundant systems (fully backed up with manual and automatic redundancy) the Mamos SmartCEMS® is offered as a complete stationary CEMS for permanent installation or long term rental.
