“…Policy coherence across multiple departments is essential; supportive policies in one sector could become ineffective when combined with policies in other sectors. Hence, policymakers must take a holistic view to create coherence between policies and instruments across different sectors (Zhu et al, 2019). We observed Sweden and Denmark using biogas sector-specific policy mix strategies to create coherence and improve policy effectiveness across multiple sectors.…”

“…These environmental benefits are not factored into financial models; therefore, policies do not effectively monetize the biogas sector for its social and environmental value contributions (ADBA, 2020). The RED II (revised renewable energy directive) issued by the EU in 2018 recognizes the negative carbon potential of AD-based biogas production from waste (Zhu et al, 2019). Using a carbon tax on fossil fuels and natural gas, Sweden effectively addressed the negative externalities in the gas market (Zhu et al, 2019).…”

Using a carbon tax on fossil fuels and natural gas, Sweden effectively addressed the negative externalities in the gas market (Zhu et al, 2019). Although biogas producers in the UK are exempted from the energy tax, which is levied on fossil fuels, the effectiveness of this exemption depends on the carbon price floor (Kampman et al, 2017).…”

Over the last decade, demand-side policies are increasingly implemented to correct market failures and overcome the systemic problem in complex social-technical systems such as energy transition. This paradigm shift in policy approach results from realizing that relying solely on supply-side policy instruments to push innovative solutions into the market is insufficient. As part of the energy transition, many developed countries have considered Biogas from Waste (BfW) based on the Anaerobic Digestion (AD) process as a realistic renewable energy source and aim to create social, economic, and environmental benefits for their communities. Despite several policy instruments in the UK over the last ten years, the growth of BfW schemes remains subdued and faces market failures. This paper aims to evaluate elements of demand-side policies focused on addressing market failures to increase the diffusion of BfW schemes in the UK. We discussed effective demand-side policies related to the biogas sector in other European countries like Sweden, Denmark, and Italy. In the analysis, we observed UK’s policy instruments do not effectively address market externalities in the biogas sector. We also observed the biomethane market share in the UK is minimal; there is no market policy for green gas labeling towards demand articulation. The paper also made recommendations for policymakers in the UK to address market failures by proposing a push-pull policy model that combines demand-side policy interventions with supply-side policies.

“…The EU could be the leader in biomethane production integrated with other renewable because of the high presence of biomethane plants, i.e., 497 in 2017 [200], with sizes that vary from 150 to 750 m 3 , and the widespread use of solar and wind technologies. Recent policies about the reduction in the use of energy crops put a restraint on the development of biomethane plants in the EU, which have had an exponential growth in the last 20 years.…”

A Review of the State of the Art of Biomethane Production: Recent Advancements and Integration of Renewable Energies

et al. 2021

Anaerobic Digestion (AD) is a well-established process that is becoming increasingly popular, especially as a technology for organic waste treatment; the process produces biogas, which can be upgraded to biomethane, which can be used in the transport sector or injected into the natural gas grid. Considering the sensitivity of Anaerobic Digestion to several process parameters, mathematical modeling and numerical simulations can be useful to improve both design and control of the process. Therefore, several different modeling approaches were presented in the literature, aiming at providing suitable tools for the design and simulation of these systems. The purpose of this study is to analyze the recent advancements in the biomethane production from different points of view. Special attention is paid to the integration of this technology with additional renewable energy sources, such as solar, geothermal and wind, aimed at achieving a fully renewable biomethane production. In this case, auxiliary heat may be provided by solar thermal or geothermal energy, while wind or photovoltaic plants can provide auxiliary electricity. Recent advancements in plants design, biomethane production and mathematical modeling are shown in the paper, and the main challenges that these fields must face with are discussed. Considering the increasing interest of industries, public policy makers and researchers in this field, the efficiency and profitability such hybrid renewable solutions for biomethane production are expected to significantly improve in the next future, provided that suitable subsidies and funding policies are implemented to support their development.

“…The production of energy from renewable sources is not only a choice resulting from the policy of environmental protection or care of the environment but is also an obligation imposed by the European Union in the form of numerous ordinances and international agreements [ 1 ]. Therefore, more and more EU countries are focusing their attention on managing waste materials from various industries for the production of biogas [ 2 , 3 , 4 , 5 ]. This approach is consistent with the theory of sustainable development.…”

Removal of Siloxanes from Model Biogas by Means of Deep Eutectic Solvents in Absorption Process

The paper presents the screening of 20 deep eutectic solvents (DESs) composed of tetrapropylammonium bromide (TPABr) and glycols in various molar ratios, and 6 conventional solvents as absorbents for removal of siloxanes from model biogas stream. The screening was achieved using the conductor-like screening model for real solvents (COSMO-RS) based on the comparison of siloxane solubility in DESs. For the DES which was characterized by the highest solubility of siloxanes, studies of physicochemical properties, i.e., viscosity, density, and melting point, were performed. DES composed of tetrapropylammonium bromide (TPABr) and tetraethylene glycol (TEG) in a 1:3 molar ratio was used as an absorbent in experimental studies in which several parameters were optimized, i.e., the temperature, absorbent volume, and model biogas flow rate. The mechanism of siloxanes removal was evaluated by means of an experimental FT-IR analysis as well as by theoretical studies based on σ-profile and σ-potential. On the basis of the obtained results, it can be concluded that TPABr:TEG (1:3) is a very effective absorption solvent for the removal of siloxanes from model biogas, and the main driving force of the absorption process is the formation of the hydrogen bonds between DES and siloxanes.
