This study evaluates two sustainable alternatives to natural gas (NG) for ceramic and glass tableware kilns. Case Study I explores direct gasification of residual forest biomass (RFB) using a circulating fluidized bed (CFB) gasifier, processing 3.68 million tons annually with 75.0% efficiency. Case Study II investigates hydrogen (H₂) production via Proton Exchange Membrane (PEM) electrolysis, producing 38.91 t/h of H₂ with 70.0% efficiency. Both configurations underwent energy and economic analyses, including capital expenditure (CAPEX), levelized cost of energy (LCO), specific cost of hydrogen production (SCHP), and financial indicators like net present value (NPV), internal rate of return (IRR), and payback period (PBP). Case Study I shows a CAPEX of 1405.32 €/kW, LCO of 64.01 €/MWh, NPV of 2300.29 M€, IRR of 16.24%, and PBP of 8.76 years, outperforming Case Study II, which has a CAPEX of 1171.28 €/kW, SCHP of 3.82 €/kg, NPV of 714.08 M€, IRR of 11.83%, and PBP of 14.93 years. Case Study I aligns better with World Bank guidelines for biomass projects, which recommend a PBP under 10 years and IRR above 10%. Sensitivity analyses highlight the impact of feedstock availability and energy pricing on feasibility. Additionally, Case Study I demonstrates significant potential for carbon emissions reduction, making it a more sustainable option for industrial decarbonization. Overall, the findings demonstrate that both configurations are viable, but Case Study I offers a more cost-effective and efficient solution, supporting the transition to clean energy in energy-intensive industries.

摘要

This study evaluates two sustainable alternatives to natural gas (NG) for ceramic and glass tableware kilns. Case Study I explores direct gasification of residual forest biomass (RFB) using a circulating fluidized bed (CFB) gasifier, processing 3.68 million tons annually with 75.0% efficiency. Case Study II investigates hydrogen (H₂) production via Proton Exchange Membrane (PEM) electrolysis, producing 38.91 t/h of H₂ with 70.0% efficiency. Both configurations underwent energy and economic analyses, including capital expenditure (CAPEX), levelized cost of energy (LCO), specific cost of hydrogen production (SCHP), and financial indicators like net present value (NPV), internal rate of return (IRR), and payback period (PBP). Case Study I shows a CAPEX of 1405.32 €/kW, LCO of 64.01 €/MWh, NPV of 2300.29 M€, IRR of 16.24%, and PBP of 8.76 years, outperforming Case Study II, which has a CAPEX of 1171.28 €/kW, SCHP of 3.82 €/kg, NPV of 714.08 M€, IRR of 11.83%, and PBP of 14.93 years. Case Study I aligns better with World Bank guidelines for biomass projects, which recommend a PBP under 10 years and IRR above 10%. Sensitivity analyses highlight the impact of feedstock availability and energy pricing on feasibility. Additionally, Case Study I demonstrates significant potential for carbon emissions reduction, making it a more sustainable option for industrial decarbonization. Overall, the findings demonstrate that both configurations are viable, but Case Study I offers a more cost-effective and efficient solution, supporting the transition to clean energy in energy-intensive industries.
