Sadly aircraft fires are not new both on the ground and in flight. I'm not sure that we will ever eradicate this risk. Thankfully: training, modern fire suppression equipment and evacuation procedures continue to save lives.

Algal fuels look promising. Currently high cost, but that should come down as investment scales up. Much more productive on a land-use basis than plant-based biofuels. Carbon neutral over its production / consumption cycle. Can reuse existing hydrocarbon infrastructure - distribution, engines - and all the R&D.

Fossil fuels are not dead. The post globalisation world will see to that. By the time legacy fossil fuels are getting difficult to extract there will be a range of synthetic liquid fuels on the market. Crude oil can be made from algae, or from thin air.
Yes, true. And at what prices? I ought to have stated "Fossil fuels are dead for use like today. They will be around where they are irreplaceable but at prices forbidding recreational use as it is today."

training, modern fire suppression equipment and evacuation procedures continue to save lives.
And all those still need to be developed/approved/documented/instructed for electric power.

What would peoples choice of powerplant/fuel be if building a new SEP right now in the 180HP area? Ive just started building an RV8 with an estimated completion date in 5 years. The availibity (and price) of Avgas for the next 30 years to enjoy the thing really worries me, I'm seriously considering looking at electric but the infrastucture isnt here to support it and the extra weight will make it rubbish for aeros...Not to mention the work to get an electric system approved by the LAA...

Is there a Jet A1 option or will that have the same issues as Avgas (espcially at the dwindling number of smaller airports in the UK...)

No crystal ball is thick or big enough for making a reliable forecast five years ahead. Some general tendencies I seem to discern - without claiming to be Jeremiah :
* diesel, or something like it, will need to be available for the sake of road transport; the first fossil fuel to disappear will be AvGas, other variants of gasoline to follow rapidly;
* five years from here, electric may have found solutions to safety issues, so that it can be applied with an acceptable degree of safety for circuit flying/training;
* for cross-country flying, all depends on infrastructure, indeed; and that will depend on state subsidies, and those will not go primarily to private aviation.

My reply to your query would be diesel - and plant a few acres of rapeseed. Except if you foresee to be happy with circling your local church spire, batteries might well develop fast enough for that.

Jet A-1 or Diesel would be my fuel to go because it's available everywhere and you need range. So maybe a RED engine or similar? Too powerful for your requirement.

The RED A03 is indeed a giant overkill for this requirement with its 500 HP - didn't we recently read here about its being certified or STD'd to a DHC Beaver? Even its A05 derivative would be too big with its 300 HP, and it seems to be only in the project phase as yet, in fact the company website doesn't even mention it any more.

The big A03 is FAA and EASA certified.

I expect to be test flying the RED03 on the Beaver in the next month or two, but it'll be a year before it's approved, lots of testing in different environments required for Canadian certification.

I think that for a new engine, your only choices will be a Lycoming 360/390, or the Austro E4 (if they're even available for such application). There is no turboprop that size, and if there were, the cost and fuel consumption would be high. Electric is the way of the future for some aviation applications, but flying will be different while we get used to not going very far with a heavy airplane.

There is a new 130 hp turbine for microlights (and drones?), the Turbotech TP-R90. It's currently being tested on the VL3 microlight replacing the Rotax engine.

Oh, one of those. Reminds me of the Zoche diesels, been announced for several decades now, still nothing really available. How many promising engines haven't been announced, without ever becoming effective, and practical? Visit Aero 2022 for this year's load.

Even in the experimental/ultralight environment - where formal certification isn't an absolute requirement - the venerable Rotax 912 is unbeatable.
