Though the EGR system and regeneration of the catalytic converter are not directly linked in function, it was the introduction of the EGR system that required regeneration so actually, the EGR has everything to do with regeneration.
Because of the inefficient design of the internal combustion engine and the related fuel systems, the
government decided that the EGR system should be developed to introduce exhaust gas back in to the engine in an attempt to re-burn more of the fuel that wasn't burned the first time around. The first problem with the EGR system is that it's a government mandate with no science behind it. The second problem is that when you reintroduce the exhaust to the engine, your reducing the amount of air going in to the engine causing it to require many other components to compensate, all of which provide the combined result of poor mileage and the need to regenerate a catalytic converter on a diesel engine to remove the resulting soot.
To get a truly cleaner burning engine you need to modify the fuel to burn more efficiently. This can be accomplished in a number of ways. Hydrogen boot causes the fuel to burn longer in the cylinder providing more complete combustion which translates to better mileage and improved performance. Another method would be to vaporize the fuel before introducing it to the engine. Fuel injection systems atomize the fuel which is better then carburetion by far but not nearly as good a vaporization. If you combine vaporization and hydrogen boost along with the proper tune of the engine you can get some very serious mileage improvements. In some cases a 50% improvement.
I worked on a project with my father-in-law back in the early 80's where we modified a Ford 3/4 ton 4WD pickup with a 400M engine, automatic transmission and 4:10 gears, to run on vaporized fuel. On a trip from Minnesota to Arkansas, we got a little over 26MPG. Prior to the modification the truck was lucky to get 14MPG. Thats almost a 100% improvement and we did that with a backyard system. Admittedly we had problems not the least of which was frequent backfire that eventually caught the carb on fire but we're not engineers so I wonder what would have happened if some automotive engineers tackled the project. We later learned that vaporized fuel burns faster then atomized fuel so we would have had to reduce the camshaft overlap to eliminate the backfires but that was beyond our capabilities. The same is true to run a vehicle on 100% hydrogen.
