Looks sound, but I'm not qualified to say if success will follow. It's certainly stable and also a low-grade fuel.

https://en.wikipedia.org/wiki/Sodium_formate

Upon heating (in the range from 253 C to 411 C), sodium formate decomposes into various compounds - either hydrogen and sodium oxalate, or hydrogen and sodium carbonate - so it's true that it can be used as a fuel without releasing the carbon. Shipping it somewhere where it gets converted back to sodium formate is the tricky part, because that seems unlikely to happen onsite (on a small site, anyway).
