Capture and transform CO2 into renewable e-methane
Landfill gas (LFG) consists of approx. 50% carbon dioxide and accounts for around 2% of global greenhouse gas emissions. As pressure intensifies to mitigate climate change by reducing emissions across all sectors, landfill operators can substantially reduce their carbon footprint by converting the CO2 emitted at landfills into clean, renewable e-methane gas.
As LFG accumulates, it can be stored and processed via carbon capture utilization (CCU) equipment, which prevents it being released into the atmosphere. This CO2 is then fed into a bioreactor, along with green hydrogen. Electrochaea’s patented methanogenic archaea then synthesizes e-methane from the feed gases to generate grid-quality e-methane.
Landfills can use this e-methane to power on-site operations (in either gas or liquid form), store e-methane on site, transport it to third-party sites or inject it into the grid. As well as reducing CO2 emissions, integrating CCU and biomethanation enables landfill operators to maximize revenue by incorporating additional value streams and producing much-needed renewable energy.
Converting waste into energy can accelerate the energy transition – but W2E plants still generate a significant amount of CO2. To minimize their environmental footprint, W2E plants can convert emitted CO2 into renewable e-methane gas, which can be used to power on-site operations, stored, transported or injected into the grid.
While organic matter can be converted into biogas, biomethane and e-methane, other types of waste, such as biomass, industrial and municipal solid waste (MSW) can also be used to generate energy at dedicated plants. What’s more – integrating Electrochaea’s biomethanation technology at W2E plants reduces carbon emissions and increases clean energy outputs.
Incorporating a Power-to-Gas (P2G) system at W2E plants enables CO2 emissions from the waste combustion process to be fed into a bioreactor along with green hydrogen. Here, Electrochaea’s proprietary methanogenic archaea synthesizes e-methane from the feed gases with a CO2 conversion efficiency rate of 98.5%.
