中文导读
Real Engineering 审视了氢能作为能量载体的实际效率，全面盘点了制氢、储存到燃料电池转换各阶段的能量损失，并直观对比了氢能源车与纯电动车。
为什么 HN 推它
HN 社区常在氢能讨论中引用此片，作为阐释多重损耗叠加为何导致氢能不适合乘用车的一流拆解（虽有评论指出部分数据略显陈旧）。
「这部视频非常清晰地拆解了氢燃料电池车各项效率损失是如何层层叠加起来的。」HN 网友原话：This video gives a good breakdown on how the inefficiencies in hydrogen fuel cell based cars add up.
英文原摘要（HackerTube / Claude 整理）
Real Engineering examines the efficiency of hydrogen as an energy carrier. It follows production, storage and fuel cell conversion losses and compares hydrogen cars with battery electric vehicles.
HN links it in hydrogen threads as a clear breakdown of why compounded inefficiencies make hydrogen a poor fit for cars, though one commenter calls it outdated.
HN 上的提及
Storing energy as hydrogen is much less efficient than storing energy in batteries.
This is a good video on the subject
It's a nonsense youtube video, citing claims that are a decade out of date.
this video had a good overview of the various production methods, including on-site at the fuel station
Nice summary as for cars fuel application here
