Hydrogen Cement Kiln Trial Tests Fuel-Mix Economics
A two-day hydrogen co-firing trial at an Austrian clinker kiln shifts attention to fuel supply, operating control and cost.
氢能水泥窑试验进入燃料组合经济性验证阶段
奥地利熟料窑完成两天氢气协同燃烧试验，关注点转向燃料供应、运行控制与成本。
World Cement reported on 27 August 2026 that Rohrdorfer completed a two-day hydrogen co-firing test at its Gmunden clinker kiln. Hydrogen covered part of the heat demand and was reported as fundamentally suitable, while economics remain uncertain.
1. High-temperature process heat
Renewable hydrogen could reduce fuel-related kiln emissions, but not carbon dioxide from limestone calcination. Total benefit depends on hydrogen production and logistics.
2. Fuel logistics and cost
Linde supplied hydrogen by truck trailer and developed a mobile unloading station. Continuous production needs dependable volume, storage and safety systems.
3. Commercial proof still lies ahead
Rohrdorfer said current hydrogen cost remains many times too high. Longer operating data is needed before comparison with electrification, alternative fuels and clinker substitution.
Takeaway: The trial is useful operational evidence, not a commercial verdict. Source: the original World Cement report, 27 August 2026.
《World Cement》于 2026 年 8 月 27 日报道，Rohrdorfer 在 Gmunden 熟料窑完成两天氢气协同燃烧试验。氢气承担部分热负荷，技术上原则可行，但经济性仍不确定。
1. 高温工艺供热
可再生氢可能减少窑炉燃料排放，但不能消除石灰石煅烧产生的二氧化碳。整体效果取决于氢气生产和物流。
2. 燃料物流与成本
Linde 使用卡车拖车供应氢气，并开发移动卸气站。连续生产需要稳定货量、储存能力和安全系统。
3. 商业化仍需验证
Rohrdorfer 表示当前氢气成本仍高出许多倍。需要更长期运行数据，才能与电气化、替代燃料和熟料替代可靠比较。
结论：此次试验提供了运行证据，但尚非商业结论。成本、氢气供应、连续运行、安全与完整排放核算将决定其能否扩大。来源：《World Cement》2026 年 8 月 27 日原始报道。
