“…Through various bonuses such as the manure bonus or the bonuses for upgrading biogas to biomethane, plants can be classified as biogas or biomethane plants. According to Scheftelowitz et al [11], the bioenergy carriers were assigned to the master-and transaction data. In recent years, the construction of biogas plants and the expansion of capacity have been slowed down distinctively compared to the preceding years.…”

This paper presents the results of a status quo analysis of biogas production in Germany. It provides detailed information regarding the biogas plant portfolio and distribution, applied technologies, types of substrates und the contribution of biogas to the electricity, heat and transport sector. The evaluations regarding biogas and biomethane are based on data from annually surveys of biogas plant operators, Federal Network Agency regarding electricity generation, German transmission grid operators regarding direct marketing of electricity, and the current plant register regarding flexibility premium.

“…The flexibility premium payment was introduced alongside the market premium in the EEG 2012 and continued-in slightly adjusted form-in the EEG 2014 [70] The goal of the flexibility premium is to encourage investments in components which are necessary for demandoriented electricity generation. For existing plants, these components are primarily new or additional CHP and gas storage capacities for biogas plants.…”

Background: With wind power and photovoltaics, volatile renewables have emerged as central pillars of the energy transition. This increases the demand for flexibility options to compensate fluctuations in power generation. Focussing on the role of bioenergy as a renewable flexibility option, this article seeks to address two questions. The first is whether there is an option value of bioenergy as a provider of low-carbon flexibility in a future power system, which might justify continued technology-specific deployment support. The second question is whether existing market and policy incentives are effective in activating flexibility potentials, and what perspectives exist for increasing flexibility incentives. Methods: The article follows an interdisciplinary approach. First, technical potentials for flexible bioenergy plants and potential systemic contributions are examined. This is followed by an economic assessment of what flexibility incentives are provided by relevant market and policy framework conditions. Findings: Power from biomass can be well suited to provide flexible generation for grid stabilisation and residual load balancing. Biogas plants require an increase of nominal power over rated power, whereas the technical flexibilisation potential of solid biomass plants depends on specific technologies. Particularly, small-scale combined heat and power systems can deliver fast responses. For existing biogas plants, the Renewable Energy Sources Act's (EEG) flexibility premium and balancing market revenues have incentivised some changes in the production behaviour and investments in plant flexibilisation. However, decreasing spot market price levels and decreasing price variance reduce incentive strength. This also limits flexibilisation incentives for solid biomass plants. For new biogas plants, the EEG's remuneration rules set effective flexibility incentives, but 2014 reductions in remuneration rates have significantly slowed down the expansion. Conclusions: Given high technical potentials for flexibility provision, there is an option value of keeping bioelectricity in the technology mix until more is known about its future competitiveness with other low-carbon flexibility options. To maintain this option value, there is a case for setting policy incentives in a way that continued technological development remains possible. A stringent climate policy could accelerate structural change in the electricity sector, to allow for market price signals which incentivise low-carbon flexibility provision.

“…. Therefore, data from different sources concerning the current use of different bioenergy carriers (liquid, gaseous, and solid biofuels) in the different sectors (transport, electricity, and heat) were combined (data for 2015 taken from , ). Based on these energy flows and published information on the resources used and the efficiencies of the production and conversation processes, including losses, residues, and by‐products, the energy flow from the resources to the energy carriers was calculated , .…”

Bioenergy carriers are used in different energy sectors. While the bioenergy supply from energy crops is limited, there is still reasonable unused potential from residues and waste. Improved qualities are necessary with regard to energy density, storability, energy content, flexible application, and related emissions. Especially solid and gaseous biofuels can be generated with reasonable effort and are suitable for utilizing the available waste and residual streams. These advanced bioenergy carriers can support the energy transition significantly, but need support for market introduction.
