Emissions of Green house gases by humankind are one of the key reasons for the raising temperature on the surface leading to climate change. According to Intergovernmental Panel on Climate Change (IPCC) report, the temperature of earth will be raising to at least 1.5 degrees centigrade in the next two decades, and possibly hotter. The main important greenhouse gases are Carbon dioxide, Methane, Nitrous Oxides, and water vapour. While World Metrological Organisation (WMO) has given that Carbon dioxide has reached 149% from the preindustrial level in 2021, Methane has increasing 15 – 18 ppb per year which is an even more effective contributor for the climate Change, given its livespan in the atmosphere. To minimise these greenhouse gas concentrations in the atmosphere, pyrolytic carbon capture and storage (PYCCS) process is possible, but another product is the so called wood gas which is the topic here. While the sequestration of solid carbon in bio char could contribute to a lessening CO2 concentration, wood gas could render this process more attractive. In this way it would be possible to reduce the CO2 concentration, while generating a storable form of energy. While hydrogen is not trivial to store, this study concentrates on methane CH4, which is already in widespread use.

Pyrolysis of biomass lignin, cellulose and hemicellulose can be described as the thermal disintegration of the material into char, liquids - pyrolysis oil and wood gases. According to the literature, wood - gas consists of Methane, Carbon dioxide, Carbon monoxide and Hydrogen. The focus of this research paper is idea to optimize Biomass pyrolysis for the methane gas output. The gas composition during the pyrolysis process of biomass waste is measured by a syn-gas analyser in a laboratory environment with controlled temperatures ranging from 300 and 700°C and thus measuring the composition and the methane quantity. Based on these results, the discussion of possible storage solutions for methane follows with an estimation of the costs that are attached.
