Method and Plant for Converting Solid Biomass into Electricity

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent discloses an integrated system and method for converting solid biomass into electricity. The invention combines biomass gasification, advanced particulate and tar removal, desulfurization, and a high-temperature solid oxide fuel cell (SOFC) in a thermally and process-optimized configuration. By integrating these units into a single, self-contained plant, the system achieves superior efficiency, flexibility, and control compared to previous separate or loosely coupled biomass-to-power approaches.

Use CasesContent extracted from patent full text and abstract with AI.

• Decentralized power generation in rural or off-grid areas using locally available biomass (e.g., wood chips, agricultural residues).
• Industrial facilities seeking to convert their biomass waste into electricity and heat (combined heat and power applications).
• Municipal solid waste management with energy recovery from the organic fraction.
• Sustainable energy generation for remote communities, reducing reliance on fossil fuels.
• Grid-tied renewable power plants supplying green electricity from biomass sources.

BenefitsContent extracted from patent full text and abstract with AI.

• Higher overall efficiency than traditional biomass power plants due to optimal heat and process integration, especially by combining gasification and solid oxide fuel cells.
• Ability to use a wide range of solid biomass types, including those with varying moisture and contaminant content.
• Substantial reduction of tar, sulfur, and particulates in the product gas, leading to cleaner operation with less maintenance and fewer emissions.
• Modular and scalable system design, suitable for applications from small communities to industrial scale.
• Improved operational flexibility and control, allowing adaptation to different biomass feedstocks and changing load demands.
• Lower greenhouse gas and pollutant emissions compared to conventional combustion-based biomass power plants.

Patent Abstract

A self-contained system for generation of electrical energy (92) from biomass (61) by gasification is disclosed, which combines several process units (1, 2, 3, 4, 17) in one self-contained system, such that the global properties are greater than the sum of the individual properties of the process units (1, 2, 3, 4, 17).
