"One of the most promising compositions features *hydrogen peroxide,
ethanolamine and special additives*. In addition to being hypergolic and
non-toxic, this combination is also environmentally-friendly and fulfills
the goals of "green" propellants. Its feasibility has been proven in past
lab-scale tests at Sandia National Labs and other organizations.
However, because its performance is generally considered lower than
conventional hypergolic propellants, it has never been adopted
commercially. Operating at higher pressures and novel mass flow rates,
Aphelion Orbitals’ design overcomes this shortcoming and achieves specific
impulse (power efficiency) approaching that of the most commonly used
rocket propellant, liquid oxygen and RP-1."

My favorite part was the "novel mass flow rates".

Interesting plan, but a crowded field.
Any idea what their non-toxic storable propellant combination was?
