It is I'm afraid looking a little bleak. Not much research, if any, is going into providing a long-term solution.
Just down the road from me, at Cotswold A/P, (the former RAF Kemble) a number of projects are underway based around hydrogen and battery technology - but neither are compatible with vintage pistons.
Most modern jet engines can be operated on SAF. Indeed in the last year, or so, we have seen trans-Atlantic flights operate with SAF. As well as the RAF operating an A330 on 100% SAF.
Whilst on Jury service, about 6 years ago, I read an Institution of Engineering and Technology (IET) article on H4O. H4O is basically very fizzy water. The article went onto describe how the product could be used in internal combustion engines (as per motor vehicles). When used it does not produce any gas waste. Indeed an exhaust system is not required. Further, it has the advantage of almost no modification to the engine. However, a modified fuel tank is required - not beyond the wit of man!! Also, the delivery infrastructure (storage tank, bowser etc) would need some modification - also not beyond the wit of man.
Could that provide a solution?

I read recently about the forthcoming demise of DDA Classic Airlines and their DC-3 at the end of this season. One of the contributing factors was that 100LL Avgas used for the Dak will be prohibited in Europe soon. This sounds very worrying for the future of at least some piston classics, especially regarding 'green' issues, climate change, etc. Unless some other 'climate friendly' fuel can be developed?
Is this the beginning of the end for most of our beloved piston 'warbirds'?
