Technical standards for biomethane and natural gas

The Act of 8 January 2010 on amendments to the Energy Act and certain other acts (Journal of Laws No 21 item 104) made some important new provisions for biogas. The law defines as non-discriminatory access to the grid, moreover, the operator of the gas distribution system, in the area of his operation, is obliged to accept agricultural biogas when in line with the quality parameters. The law is limited to biogas from agricultural sources, from wastes from food industry and from forest biomass in the methane fermentation process. It is expected that landfill gas and sewage gas are restricted from the grid. By all means, the biomethane producer is obliged to prove the hygienic harmlessness of the injected biomethane before the delivery of biomethane to the distribution network, and again when changing the applied technology.

Requirements for gas quality

The requirements for biomethan quality in the grid are specified in the Regulation of the Minister of Economy of  August 24, 2011on detailed of obligation concerning data confirmation about produced agricultural biogas introduced into the gas distribution network (Dz.U.2011, no. 187,item 1117)

The requirements  for natural gas quality in the grid are specified : Polish Standards PN-C-04752:2011 and PN-C-04753:2011. 

There are two gas qualities in Poland, high-methane gas - with a minimal required calorific value of 34.0 MJ/m3 and nitrogen-rich gas with a minimal required calorific value 18.0 MJ/m³. 

Grid access restrictions

The law defines as non-discriminatory access to the grid, moreover, the operator of the gas distribution system, in the area of his operation, is obliged to accept agricultural biogas when in line with the quality parameters. The law is limited to biogas from agricultural sources, from wastes from food industry and from forest biomass in the methane fermentation process.

Barriers

The barrier for biomethane injection into the gas grid in Poland is high costs of biomethane production which are not cover with regulate price. Investor have to bears all the investment costs for biogas upgrading plant and grid connection.  The other barriers are insufficient and non-long approach support scheme. Also legal framework should be more restrictive. DSO operators may set unrealistic demands for grid access. There are also technical reasons concted with preasure and low amount of high pressure regulating station.
