In many cases a methane estimate will miss the real extent of emissions. Bluemethane provides solutions to precisely measure and monitor dissolved methane, facilitating accurate reporting of emissions.
Most gases are emitted through the degassing stage. Bluemethane technology consists of two stages, a degassing unit and a low vacuum system.
Having confidence in your dissolved methane data is vital for accurate reporting of emissions. This is why Bluemethane is offering a low-cost, continuous methane measuring service to ascertain cyclical methane emissions. Using this data, Bluemethane can determine the potential revenue that can be gained from mitigating these emissions, and asses the benefit in deploying recovery technology.
Bluemethane’s solutions seamlessly plug into industrial and municipal wastewater infrastructure, delivering operational and financial benefits alongside long-term climate impact.
Carbon dioxide has been well mapped. However, sources of methane are only starting to be fully understood. Below are some explanations to understand this area further.
Whether it is to know your emissions and report them or to understand how you can utilise the methane at different points, Bluemethane can scope these emissions in detail.
Our measurement system is based on UNESCO and IHA guidelines (2010). Our protocols are customisable. We formulate a sampling plan for each case based on the needs and site conditions. Our current approach includes high-resolution sampling and gas chromatography analysis in the laboratory. Finally, we obtain a mapping of methane and other gases if required, as well as seasonal variability. Our report contains the potential use of methane according to the results and recommendations.
There are very few points of methane emissions from the water line treatment of municipal sewage. The main sources of methane emissions is from anaerobic reactors, where methane is produced, but not always utilised.
For example, the Chemical Oxygen Demand (COD) in the feed to Upflow Anaerobic Sludge Blanket (UASB) varies between 2,000 and 10,000 mg/l. 2,000 mg/l as being the worst case. With an assumption that 70% of this is converted to methane – 1,400 mg/l of COD is converted to methane, which gives a total of 350 mg/l of methane produced. Thus about 8.5% of the methane produced is dissolved in the effluent. The dissolved methane in the effluent of a typical UASB will be than about 30 mg/l.
There is increasing evidence supporting the need to reduce methane emissions. President Biden has proposed the price per tonne of methane emissions to be $1,500 because “these emissions cause more warming, health impacts, and economic damage in the short term.”
We estimate the potential market for carbon offsets from reservoirs to be in excess of £20bn.
