Report Substrate Materials for intersectoral biogas strategy

Foreword

In Climate Report (Meld. St. 21 (2011-2012)), the Government decided that it should develop a national, cross-sectoral strategy to increase the production and use of biogas in Norway. In November 2012 was Climate and Pollution Agency (CPA) in the Ministry of the Environment to prepare a support material to this strategy.

Biogas is a renewable source of energy that can be produced from resources that are seen as by-products or waste. This report briefly describes how biogas can be produced and applied to various purpose and how the residual product of biogas production - organic fertilizer - can be utilized. Furthermore, we provide a overview of the status of biogas production and use in Norway, before we look at the possibilities of increase production beyond current levels. Because it's remaining potential in the short term is utilization of organic waste and manure, it is these two raw materials we have looked at.

We compile cost and benefit effects for the production and use of biogas, focusing on use of biogas as fuel and feed into an existing natural gas network. Finally, we describe existing measures and barriers, before pointing to possible new instruments to trigger the various parts of the potential.

The report was prepared for the period November 2012-April 2013 by CPA with professional input from a reference group consisting of Transnova, Enova, the Norwegian Public Roads Administration (VD), Norwegian Agricultural Authority (SLF), Customs and Excise (TAD) and the Norwegian Water Resources and Energy Directorate (NVE). In addition conducted a survey to identify barriers and measures and to update cost figures, as well as a proposal meeting with about 50 participants from industry and individual meetings with several actors. Bioforsk v / Senior Tormod Briseid, Institute of Transport Economics (TOI) v / researcher RolfHagman and Waste Norway v / Henrik Lystad and Roy Ulvang has also provided technical input.

We thank everyone involved for valuable discussions and suggestions!

Summary

Biogas is a renewable energy source that can be produced by various organic materials and may

used for many different purposes such as electricity generation, heating and transport.

Production and use of biogas has many beneficial effects, such as reduction of

greenhouse gases and ammonia, recycling of nutrients, reduction of local air pollution and

production of biofuels without seizing arable land.



Potential

We estimate the realistic potential for biogas production in Norway to 2020 to be around 2.3

TWh. Only a small part of the potential has already triggered; currently produce around 0.5 TWh of

biogas. The remaining realistic potential for biogas production in the short term is dominated by

organic waste (less than 1 TWh) and manure (approximately 0.7 TWh). In the longer term,

other material such as forest waste, algae and sludge from aquaculture be appropriate for

biogas production and can increase the potential significantly. Improvements in the production process will increase

potential further.

The theoretical potential for biogas production in Norway is in earlier studies estimated to be

about 6 TWh. Not all the raw materials are available for biogas production, since some already applied for example, feed production or are very difficult to exploit for biogas production. We estimate the realistic potential for biogas production in the short term (to 2020) to be around 2.3 TWh. Only a small part of the potential is already triggered, currently produced around 0.5 TWh of biogas, see Figure 1 About half of the current production is collected landfill gas, of which an estimated half utilized for energy purposes and the remainder is flared. Production of biogas is now very common in treatment of sewage sludge where the majority of the potential is already exploited. This substrate is therefore not be discussed further in this report.

The remaining realistic potential for biogas production in the short term is therefore dominated by

organic waste (less than 1 TWh or 880 000 t of waste) and manure (approximately 0.7 TWh), see

Figure 2 Organic waste includes both food waste from households, large households and commerce,

as well as waste from commercial activities, such as waste from fish harvesting, bakeries, butchers etc.

assessment of the realistic potential is taken into account that part of the wet organic waste

already utilized for such feed production. As shown in Figure 2, the potential for

energy output divided almost equally between manure and waste, given that the potential is triggered

(880 000 tonnes of organic waste and 3.9 million tons of manure).

The potential for biogas production as we have assumed in this report are for biowaste

waste based on that 50% of food waste from households and 80% of food waste from

large households and commerce are separated and collected. Today's rejection rate for food waste from

households around 30%, which means that it requires a significant increase in sorting at source of

food waste to release all the realistic potential. The potential for manure implies that

30% of manure to be treated in biogas plants, cf. Report. 39 This is an ambitious

objective and it will require strong measures to trigger the supply of raw material to

biogas production by 2020. In the longer term, other feedstock such as forest waste, algae

and sludge from aquaculture be relevant for biogas production and thus increase the potential considerably.

Improvements in the manufacturing process could increase potential further.

Figure 1: Potential for biogas production in Norway 2020

Figure 2: Potential for biogas production in energy units based on manure and organic waste

Treatment of the entire realistic potential can be achieved by for example the following

combination of fixed size and number of plants:

 38 industrial facilities for manure at 110 000 tonnes / plant

 55 major public facilities for manure at 55 000 tonnes / plant

 16 plants for wet organic waste processing 55 000 tonnes / plant

We have used this as the basis for the calculations. However, also other combinations

be possible.
