Biomethane roadmap for Austria BIOMETHANE WS: LONDON 16.12.2015 [Franz Kirchmeyr, Austrian Compost & Biogas Association]

Developement of biogas and biomethane in Austria CHP ~ 290 plants producing electricity and heat ~ 550 GWhel. + 300 GWhth. Biomethane production 12 plants have installed an upgrading system and connection to the gas grid ~ 2500 m³ installed capacity ~ 15 Mio Nm³ biomethane production capacity but not reached jet One new plant is running to treat spent grain and produce steam and heat

Currently used feed stock versus potential Biogas as key technology using the left overs from previous production steps as food, feed or chemistry production and organic waste

Fortunately we have two very good developed energy grids: Power and gas grid 2050 climate and energy targets without involving the gas grid would cause is a great mistake

Current situation - Challenges Change in used feedstock with a big potential from non food/feed sources We expect a further technology jump of the technique Current energy situation is not a driver for further development Good cooperation between biogas and natural gas stake holders Due to expected development of energy and climate targets 2050 without acting the natural gas grid would be the fasted loser withing fossil fuels ~ 180 methane filling stations ~ 10 000 methane cars „already“ running Big lack Political interest Market demand Only a few cities with methane busses Only few lorries CHP after grid injection is at the beginning We need an agreement on political level about the future part of the gas grid and biomethane in a 2050 target

Thank you for your attention!

Impact of landfill directive, waste frame work directive and circular economy Landfill directive (1999/31/EC) Article 5 point 2b: from 2009 on less than 50 % of biodegradable waste should be landfilled (in comparison to 1995 Article 5 point 2 c: from 2016 less than 35 % of biodegradable waste should be landfilled (in comparison to amount from 1995) Waste framework directive (2008/98/EC) Article 10 point 2: Member States shall take the necessary measures to ensure that waste undergoes recovery operations, in accordance with Articles 4 and 13. Circular economy

Impact of landfill directive, waste frame work directive and circular economy Waste framework directive (2008/98/EC) Article 10 paragraph 2: ensure that waste undergoes recovery operations Article 10 paragraph 3: to improve recovery, waste shall be collected separately if technically, environmentally and economically practicable and shall not be mixed with other waste or other material with different properties. Article 11 paragraph 1: promote high quality recycling and, to this end, shall set up separate collections of waste where technically, environmentally and economically practicable and appropriate to meet the necessary quality standards for the relevant recycling sectors. Article 22 paragraph 1: if possible: (a) the separate collection of bio-waste with a view to the composting and digestion of bio-waste; (b) the treatment of bio-waste in a way that fulfils a high level of environmental protection; (c) the use of environmentally safe materials produced from bio-waste.

Impact of landfill directive, waste frame work directive and circular economy Will be introduced and become a big driver for biogas/biomethane
