This sounds awesome and is really way above my head (took crystal chem in college, that's probably my highest chem level).

Some questions:

1. How many kW/kg required to create H2O2 (or another similar, meaningful ratio), and how much do the legacy processes require?

2. When you mention micromanufacturing, how small a scale are we talking about? Would I be able to buy a reactor and make H2O2 in my garage? Or open up a warehouse sized factory in my town?

these are some great questions! kW/kg is really the magic number but very difficult to extract precisely (we do have estimates though from energy balance calculations). A more qualitative way to look at energy cost comparisons is to look at downstream processing after H2O2 is synthesized. Today, they do liquid-liquid extraction, then distillation, then for high purity, they will do up to 5 sequential reverse osmosis operations. Because we do our processing in water rather than alkylated aromatics, we can use ultrapure water from the start...so we don't have to do much downstream processing to get an equivalent H2O2 purity

2. haha micromanufacturing here is relative. Today, an anthraquinone plant consumes the energy of a small city and is multiple football fields in size. They cost >$100m to make. Many of the customers that we talk to use $1-$5m per year of hydrogen peroxide but cannot justify investing in such infrastructure. Our units are modularly designed but will still be close to a football field in size. They address these medium-sized peroxide users that make up the vast majority of H2O2 end-use cases. Today, they pay as much in shipping as they do for the actual hydrogen peroxide. Our units seek to address this. How big is your garage though? Maybe we could make this work!

What is the minimum size you could make it (footprint and capacity)? How small are your laboratory-scale generators today? What would you say about minimum size while remaining economically viable, not simply theoretical?

Seems the process is simplified in terms of stages over the existing pipelines,lending itself to smaller scales.

Well our current facility takes up ca 2000 square feet and has sufficient capacity for our new consumer product launch, it really depends on what you want to do with the peroxide. If you want to compete on price against the current process though, it still has to be a lot bigger than our pilot facility.
