PROBLEMATIC GERMAN BIOGAS SECTOR – RISKS AND OPPORTUNITIES Biogas allows multiple uses: electricity, heat, vehicle fuel and a substitute to natural gas
(Strzalka et al. 2017). Historic political support as an alternative to fossil and nuclear energy sources
(Markard et al. 2016). By 2013, Germany was the frontrunner in agricultural biogas (Markard et al. 2016): o around 7,700 installed plants, o 25 TWh electricity generated, o equivalent to 4.7% of the country’s electricity consumption. WORKSHOP - SOCIAL RESEARCH IN THE BIOECONOMY

PROBLEMATIC GERMAN BIOGAS SECTOR – RISKS AND OPPORTUNITIES Despite the growth in the sector, the technology is
accompaigned by strong criticism, linked with: o competition with food production, o causing corn monocultures, affecting soil quality
and biodiversity,
o increased rental prices for arable land, o odor and traffic nuisances in the surrounding
communities (Kabasci et al., 2012; Sperling, 2012; Emmann and Theuvsen, 2012). Additional negative image due to subsidies for
renewable energy, paid ultimately by consumers (Leprich et al., 2013).

PROBLEMATIC GERMAN BIOGAS SECTOR – RISKS AND OPPORTUNITIES Consequence: the government
has reduced previously favorable regulatory support for biogas production; This provokes a collapse in the
biogas market and leaves the technology with an uncertain future (Markard et al. 2016).

METHODOLOGY DATA COLLECTION AND ASSESSMENT Research questions Which risks do stakeholders of the German biogas
sector perceive when assessing biological methanation as part of the domestic biogas value chain? How relevant do they perceive these risks to be?
Which implications may these risks entail?
Which risk management options do they suggest? Who
do they expect should take action?
WORKSHOP - SOCIAL RESEARCH IN THE BIOECONOMY
Additionally What do they believe led to the current
situation of the biogas sector in Germany? and What future do they expect for the German
biogas industry?

METHODOLOGY DATA COLLECTION AND ASSESSMENT Risk categories
Risk indicators
Economic Aspects
(I2) Large transportation costs when large demand on manure and biowaste. (I3) Not profitable biomethane production from biogas plants fed only with manure and biowaste.
Table 1. List of indicators for the survey assessment. Assessment with a Likert Scale  Probability (Likelihood)  Severity (Relevance) 1= Not probable / Not severe 5= very probable / very severe
(I1) High investment costs for the establishment of electrolysis reactors.
(I4) Existence of technologies competing for the use of excess renewable electricity. (I5) Alternative and more profitable uses of hydrogen. Political Conditions
Technology Performance
Environmental Impact Social Issues
(I6) Insufficient economic incentives for the implementation of biological methanation. (I7) Missing incentives to support the use of biomethane in the chemical industry. (I8) Missing incentives for the environmental benefits of the biogas sector. (I9) Possible explosions by handling hydrogen in biogas facilities. (I10) Low conversion efficiency of CO2 and H2 into CH4 in biogas reactors. (I11) Unpractical management of pure cultures in upscaled installations. (I12) Not enough locally available feedstock (manure and biowaste). (I13) GHG emissions from long transportation distances of manure and biowaste. (I14) Persistent methane leakages in biogas plants. (I15) Impact on water bodies by not appropriate management of digestate. (I16) Intense odor emissions. 4/1/2017 (I17) Skeptical or negative public perception of this innovation as part of the biogas sector. Source: own elaboration.

METHODOLOGY DATA COLLECTION AND ASSESSMENT Criteria for the identification of stakeholders
A person who has been working with the biogas or biomethane technology for several years in science, industry or politics. Someone who has published or is currently researching on biogas, biomethane and the nexus with the bioeconomy or directly with the technology of biological methanation. A participant who works for an association or political organization in the field of biogas and the uses of biomethane (energy/fuel/chemical platform).
