Hydrogen peroxide to oxidize a liquid hydrocarbon isn’t new; it goes back near the beginning of liquid fuel rocketry. The Me163 Komet used a variant of this method.
Concentrated H2O2 is nasty stuff, but a lot less nasty than hydrazine or nitrogen tetroxide.
Good to see research and practical development along this line continuing.
Komet’s engine is on display at USAF Museum, Dayton, OH

H202 and methanol/hydrazine/water mix along with calcium permanganate / sodium permanganate / water. Placed in two separate containers.
The tank with peroxide was made of glass (since peroxide burns right through most anything else, people, cloth, metal esp. aluminum)
The tank with the permanganate was made of aluminum.
Read somewhere the supply tankers marked T (the peroxide) and C (the permanganate) were never allowed withing 800 feet of each other. When mixed they self ignite. Tanks onboard the craft meticulously filled. Still pilots got dissolved on board apparently.
