This questionnaire is part of the EU project TITAN. It aims to collect biogas project developers' and investors perspectives on technical feasibility, economic viability, integration challenges, business models, and regulatory needs. Results will feed into practical deployment guidelines and scale-up roadmaps, bridging the gap between TITAN's technology push and industry pull.
The estimated time to complete the questionnaire is 10–15 minutes. Your answers will be treated confidentially, and results will be presented in aggregated form only.
Introduction to the TITAN project
TITAN is a European Horizon project developing an innovative technology to convert biogas directly into renewable hydrogen (H₂) and solid carbon materials using microwave-heated catalytic processes. This offers biogas plant operators a new high-value revenue stream beyond traditional electricity generation or biomethane grid injection, particularly for large to very large biogas plants near hydrogen and/or carbon materials demanding areas.
Core process Biogas (primarily CH₄ + CO₂) is fed into a catalytic fluidized bed reactor where microwave heating provides rapid, localized energy transfer to the catalyst—avoiding combustion-based heating inefficiencies. Two key reactions occur simultaneously:
1. Methane cracking: CH₄ → 2H₂ + C(s)
2. Dry reforming: CH₄ + CO₂ → 2H₂ + 2CO
The reactor output gas (H₂ + CO + residual CO₂/CH₄) undergoes water-gas shift (CO + H₂O → H₂ + CO₂) to maximize hydrogen yield, followed by purification (e.g., PSA or membranes) to produce highpurity renewable H₂ suitable for fuel cells, industrial processes, or blending.
Unique Value Proposition
Solid carbon byproducts are recovered and valorized as soil amendment (improving soil structure/fertility). This integrated carbon capture provides negative or very low lifecycle emissions, enhancing sustainability credentials under EU taxonomies and RFNBO criteria.
Scale & Maturity
TITAN targets TRL 5, demonstrating the process at ~0.5 Nm³/h biogas scale and evaluating its technical and economical feasibility to up to 30000 Nm³/h biogas. The modular design of the TITAN prototype facilitates integration into existing plants with minimal downtime, standard utilities (electricity, steam), and reasonable space requirements
