Description

Location: CH - Switzerland
This datasets describes the production of methane from wood. The feedstock is first gasified and then methanised. This dataset describes methane production through a fluidised technology. Gas composition (% mol.) of the gas is 96% CH4 (min.). Density is 0.752 kg/Nm3. Lower heating value of the gas is 34.4 MJ/Nm3. Process heat is supplied by methane combustion. Inventory refers to the net production of 1 Nm3 syngas. Net methane yield is 0.270 Nm3/kg of wood (dry matter) with a conversion efficiency (lower heating value of the methane/lower heating value of the required wood) of around 50%.

[The full documentation of this dataset was originally provided in the corresponding ecoinvent report from the Swiss Centre for Life Cycle Inventories, which is accessible for free to guests and users of ecoinvent version 2 (https://www.ecoinvent.org/login-databases.html). The dataset may subsequently have been subjected to central changes to the database, as described in the respective change report for each new release.]
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.

Technology

Gasification technology is FICFB (fast internally circulating fluidized bed of the BCL type). Technology for methanation is developed by PSI.
