美国能源部发布清洁氢生产标准指南 设4.0千克二氧化碳当量/千克氢门槛

美国能源部依据《基础设施投资与就业法》(IIJA, Public Law 117-58)第40315条发布更新版《清洁氢生产标准(CHPS)指南》,文件标注为2023年6月。草案曾于2022年9月21日公开征求意见、11月14日截止,共收到约120份意见;更新版据此采纳well-to-gate(从井口到厂门)核算边界,并确立清洁氢生产全生命周期温室气体排放目标不高于4.0 kgCO₂e/kgH₂,与《通胀削减法案》45V条款「合格清洁氢」的法定定义保持一致。

指南说明,该目标可由采用高捕集率碳捕集的化石路线、主要使用清洁能源的电解水制氢、以及部分生物质路线达到;DOE并表示未来可能随产业成熟下调该门槛。作为DOE的提案性指南,其本身不构成税收抵免规则——45V最终规则由财政部/IRS发布。

与绿色氢氨醇的关系:该门槛是美国绿氢及其下游绿氨、绿色甲醇项目判断原料碳强度的基础口径;指南在引述法条所要求「支持多种来源的清洁氢生产」时,明确把「氢载体燃料(包括乙醇和甲醇)」列入法定来源范围,是甲醇作为氢载体进入美国政策文本的正式表述。

英文原文摘录:"Based on the BIL’s statutory factors and stakeholder feedback, the CHPS establishes a target for well-to-gate lifecycle greenhouse gas emissions of ≤4.0 kgCO2e/kgH2."

英文原文摘录:"This target is also consistent with the IRA’s definition of “qualified clean hydrogen.”"

英文原文摘录(法条引述):"...“support clean hydrogen production from each source described [42 U.S.C. § 16154(e)(2)],” (e.g., including but not limited to fossil fuels with carbon capture, utilization, and sequestration (CCUS); hydrogen-carrier fuels (including ethanol and methanol); renewable energy resources, including biomass; nuclear energy)."

英文原文摘录(DOE官网说明):"This updated guidance establishes a target of 4.0 kgCO2e/kgH2 for life cycle (defined here as 'well-to-gate') greenhouse emissions associated with hydrogen production."
