Abstract
Over the past decades, global efforts have been made to address climate change and improve the well-being of our planet. The European Union (EU) has set ambitious greenhouse gas (GHG) emission reduction targets and strategies to combat climate change. Bio-energy, specifically biofuels produced from biomass, has gained significant attention as a crucial component in decarbonizing energy and production systems. While renewable energy sources like solar and wind are primarily used for electricity generation, bio-based processes focus on producing biofuels for heat, power, transportation, and biochemistry sectors. Therefore, biomass can play a crucial role in decarbonizing hard-to-abate industries that are challenging to electrify, such as the chemical industry, heavy road transport, and marine and aviation sectors. However, the chemical industry, a major energy consumer and emitter of CO2, relies heavily on fossil fuels as feedstock and energy sources, necessitating a shift to carbon-free alternatives.
The biomass-to-syngas pathway, which involves converting biomass into bio-based syngas through gasification, has emerged as a promising solution for a more sustainable chemical industry. However, the development of this value chain faces technical and commercial challenges. Technical challenges include tar formation and product impurities, while commercial challenges include financing limitations, low market maturity, and sustainable feedstock availability. Moreover, handling and using biomass as a feedstock itself present constraints such as transportation limitations, variable composition and properties, low energy density, and high moisture and oxygen content. These challenges hinder the competitiveness of bio-based syngas production against fossil fuel alternatives and impede the development of the biomass-to-syngas value chain.
To address these challenges, the integration of torrefaction technology into the value chain has been proposed as a promising approach. Torrefaction enhances biomass densification, reduces moisture content, and improves the overall viability of the biomass-to-syngas value chain. However, the commercial implementation and economic feasibility of torrefaction remain uncertain. Additionally, research primarily focuses on technological improvements and lacks a deeper understanding of system integration, practical implementations, and stakeholder perspectives.
This research aims to bridge these knowledge gaps by actively engaging with stakeholders across the value chain to address the challenges of developing the biomass-to-syngas value chain and propose comprehensive solutions through stakeholder involvement. It explores the system integration of torrefaction technology, considering industry stakeholders' perspectives. The research employs a step-wise approach, focusing on an in-depth case study of the Dutch chemical industry. Data is collected through an exploratory literature review, semi-structured interviews with stakeholders, a questionnaire, and a webinar serving as a panel discussion platform.
The research identifies 44 barriers hindering the development of the biomass-to-syngas value chain and the integration of torrefaction technology. These barriers primarily stem from deficiencies in innovation-specific institutions, network formation and coordination, and the production system. Stakeholders and experts agree that technological and logistical challenges can be overcome. However, addressing failures in innovation-specific institutions, such as the lack of economic and policy incentives and an unfavorable regulatory environment, is crucial for driving the development of the value chain. Based on these findings and insights obtained through expert reflection the research develops comprehensive solution statements and formulates five strategies to address the identified barriers, including cohesive policies, industry-tailored subsidies, standardized certifications and regulations, enhanced network formation, and decentralized torrefaction technology integration.
In conclusion, this research underscores the significance of the biomass-to-syngas pathway as a key driver for a sustainable chemical industry. By addressing technical and commercial challenges and the integration of torrefaction technology, comprehensive strategies have been formulated to overcome barriers and unlock the value chain's full potential. These findings thereby provide actionable insights for policymakers and industry stakeholders to drive the sustainable development of the biomass-to-syngas value chain.
