We are fighting climate change by permanently removing methane from water.
Our technology will reduce global warming and support the energy transition by unlocking a new source of bioenergy.
We are starting with hydropower reservoirs and wastewater treatment and will scale to non-hydropower reservoirs, rice cultivation and ultimately, natural bodies of water.
Methane (CH₄) is also a potent greenhouse gas, meaning it affects climate change by contributing to increased warming.
Methane accounts for about 30 percent of the increase in the global temperature since industrialisation.
The most commonly used metric to quantify greenhouse gas emissions is known as GWP100. This metric looks at the Global Warming Potential (GWP) of the greenhouse gases over 100 years. For example, methane has a GWP of 34 over 100 years. This means 1 tonne of methane is equal to 34 tonnes of CO2 over 100 years and therefore holds 34 times more heat per molecule compared to CO2.
However, methane has a short lifetime in the atmosphere – around 12 years. Over 20 years, its GWP is more like 84 compared to CO2.
Cutting methane emissions is the fastest opportunity we have to immediately slow the rate of global warming.
At the moment, we use a conservative GWP of 34 for our conversion.
We are starting with wastewater and hydropower reservoirs.
For each average wastewater plant processing 1 m3 of water per second, with 40g of methane per m3, at 80% methane removal efficiency, this would permanently prevent 1,009 tonnes of methane per year (34,300 tonnes of CO2e using GWP of 34).
For an average hydropower reservoir where our technology can process at least 50m3 of water per second, with 3g of methane per m3, at 80% methane removal efficiency, this will permanently remove 3,784 tonnes of methane per year (or 129,000 tonnes of CO2e using GWP of 34).
Bluemethane’s licencing model will generate four new revenue streams:
Wastewater and reservoir projects break even within average expected ranges for each of those sectors.
There are no relevant carbon methodologies for the removal of methane from water. We are partnering with a leading standard developer for this new standard.
Our market is global. This includes:
Wastewater utility companies with high methane in their process emissions who do not have a cost-effective way to reduce them.
Energy companies whose hydropower reservoirs have dissolved methane, making it challenging to meet emissions targets and access competitive finance when refurbishments are needed, or even to start new projects.
Owners of lakes, non-hydropower reservoirs, rice cultivation, wells – all with dissolved methane.
It is a huge unaddressed market opportunity.
Yes.
Regulatory and corporate pressures across wastewater and energy sectors are driving demand for solutions to mitigate methane emissions.
Hydropower and water treatment companies are both subject to external regulations and are accountable to meeting corporate emissions targets.
We submitted two patent applications ifor the removal of methane from water in different environments including wastewater, rice paddies, gas fields, wells as well as other sources of freshwater.
In a 2022 FTO analysis, no infringement issues were identified.
We continue to develop proprietary models and prioritise a strong protection strategy.
Compared to Bluemethane, alternative approaches to remove dissolved methane from water (membrane-based technologies, degassing towers) cannot be scaled for applications in large freshwaters. This stems from the fact that both membrane-based technologies and degassing towers require large energy inputs both initially and throughout their lifetimes. That’s why some of the largest water degassing plants can only process up to one cubic meter per second, an insignificant volume considering average flows in excess of 50m3 per second in some of the most productive hydroelectric reservoirs.
We are different because we:
Our latest prototype reached methane removal efficiencies of up to 80% in a lab in December 2022.
We are working towards our next prototype version to be deployed at Lake Kivu in Rwanda by Q2 2023. For this, we are partnering with an energy company, Shema Power Lake Kivu, to extract methane from the middle and upper layers of Lake Kivu. We expect to reach removal efficiency of at least 80% and reach TRL7.
The path to increased and predicable methane removal efficiency relies on further process optimisation. As there is no research or analysis focused on optimising methane removal from water using degassing, we are creating new models and knowledge.
Yes. We capture methane that would otherwise escape as a waste product into the atmosphere, and instead use it as a new source or renewable energy. Therefore, we convert a low value material to a higher value resource.
Hydropower is a low-carbon renewable energy source, with life time emissions similar to solar and wind. However, a small minority of reservoirs can emit large quantities of methane.
These outlier reservoirs can achieve lower carbon footprints with our solution to mitigate their methane emissions.
