TL;DR: The Energy research Centre of the Netherlands (ECN) and Dahlman Industrial Group have developed a flexible tar removal process as discussed by the authors, which is currently applied within the Substitute Natural Gas (SNG) production process based on indirect gasification.
Abstract: The Energy research Centre of the Netherlands (ECN) and Dahlman Industrial Group have developed a flexible tar removal process. This oil-based gas washing process, OLGA, besides tars, also removes dust as well as contaminants like thiophenes and dioxins from the product gas of a (biomass) gasifier. At ECN, the OLGA technology is currently applied within the Substitute Natural Gas (SNG) production process based on indirect gasification. As OLGA removes tars, but not the valuable lighter hydrocarbons like methane (CH 4 ), acetylene (C 2 H 2 ), and ethylene (C 2 H 4 ), it plays a crucial role in high-efficient SNG production processes. The OLGA in the past has been demonstrated successfully upstream Fischer-Tropsch diesel (FT) synthesis and in Combined Heat and Power (CHP) line ups as well though, where in the latter case besides the crucial tar removal it showed also to remove dioxins present in the product gas. As such, OLGA plays a crucial role in the production of clean heat and power.

TL;DR: In this paper, the authors compared the well-to-wheel (WtW) emissions from the use of bio-methane in heavy duty engines with those from currently used fossil alternatives: CNG, LNG, and diesel.

TL;DR: In this article, the authors compared and evaluated two distinct process configurations and their implementation with power-to-gas technology in Aspen Plus v.8 and found that the two cases proved to have similar efficiency; however, the integration of and carbon capture and storage technologies resulted in a negligible reduction in the efficiency of the system (approximately 1%).

TL;DR: In this paper, an original Power-to-SNG process combining high-temperature steam electrolysis and CO2 methanation is implemented and simulated, and the reference case allows to produce 67.5 Nm3/h of SNG with an electrical energy consumption of 14.4 kW h/Nm3.

TL;DR: In this article, the carbonaceous material is first pyrolyzed, then subjected to steam reforming to produce a syngas, which is then passed to several clean-up steps then to a methanation zone to produce synthetic natural gas.
Abstract: The production of synthetic natural gas from a carbonaceous material, preferably a biomass material, such as wood. The carbonaceous material is first pyrolyzed, then subjected to steam reforming to produce a syngas, which is then passed to several clean-up steps then to a methanation zone to produce synthetic natural gas.
