高能燃料是一种添加了硼烷添加剂的航空煤油。高能燃料可以大幅提高军用飞行器的航程，被用于诸如XB-70战神侍婢式轰炸机，XF-108轻剑战斗机，CIM-10飞弹等项目上。硼烷的能量密度非常高，可以当燃料添加剂。

高能燃料的缺点是容易累积在引擎内部、废气有毒及高成本；因此只在后燃器上燃烧高能燃料，这样可以完全避免堆积问题，后燃器很少开启的特性，也让有毒废气排放大幅减少。

Zip fuel, also known as high energy fuel (HEF), is any member of a family of jet fuels containing additives in the form of hydro-boron compounds, or boranes. Zip fuels offered higher energy density than conventional fuels, helping extend the range of jet aircraft, a major problem for the military planners in the 1950s. A number of aircraft were designed to make use of zip, including the XB-70 Valkyrie, XF-108 Rapier, as well as the BOMARC, and even the nuclear-powered aircraft program. In testing, the fuels proved to have several serious problems and the entire effort was eventually canceled in 1959. It was later claimed that the Blackstar spaceplane uses zip fuel, but Blackstar is almost certainly mythical.
