In the global GX context
This case study on Bangladesh's green hydrogen potential provides a model for developing economies transitioning from fossil fuels. The cost analysis and policy recommendations (subsidies, carbon pricing) contribute to the global hydrogen discourse, especially relevant for IRENA and IEA frameworks.

📄 Abstract（原文）
"ELEMENT 81:Green Hydrogen as a Replacement of Fossil Fuel" is a research-based clean energy project focused on replacing fossil fuels in Bangladesh using Green Hydrogen technology. The project demonstrates how renewable energy sources like solar power can produce hydrogen fuel through electrolysis of water. Unlike fossil fuels, Green Hydrogen produces almost zero carbon emissions, making it an environmentally friendly and sustainable energy solution. Bangladesh faces a deepening energy crisis from declining gas reserves, high fuel imports, and growing demand. Green hydrogen-produced by splitting water with renewable power-offers a net-zero-carbon alternative. This paper analyzes the technical, economic, environmental, and policy dimensions of replacing fossil fuels with solar-derived hydrogen in Bangladesh. We review Bangladesh-specific research (e.g. Mazumder et al. 2021[1], Islam et al. 2026[2]) and global data (IEA, IRENA). Key findings include: Bangladesh's strong solar potential supports competitive hydrogen costs (e.g. LCOH ~ BDT 3.41/kg in a DU study[1], ~USD 2.6-4.2/kg in techno-economic models[2]). PEM and alkaline electrolysers are mature; AEM and SOEC are emerging (see Table 1). Small pilot plants (100 W-5 kW) can serve research, while mid (3-5 kW) and large (20-100+ kW) systems can supply industry (see Tables 2-4 from user models). Hydrogen storage options include high-pressure tanks, liquid H₂ (LH₂), and chemical carriers; each has trade-offs. A green hydrogen economy would cut GHG emissions by avoiding CO₂ from gas, and supply valuable O₂ byproduct to industries and hospitals. Economically, high CAPEX (currently ~$600-2500/kW[3][4]) is the main barrier. Financing schemes, carbon pricing, and auctions are needed. Our recommended roadmap (Figure 1) starts with R&D and pilot projects (2024-2027), then policy frameworks and infrastructure (2025-2030), leading to commercial scale-up by 2030. With proper policies (subsidies, feed-in tariffs, standards) and workforce training, Bangladesh can build local supply chains. The project supports SDG 7 (clean energy), 9 (industry/innovation), and 13 (climate action). Detailed assumptions, cost models, and design parameters are provided in the appendix.
