Nameworth has it at $14,500 - registered at 3 inactive (.info, .net, .xyz), one active barebones site (.uk)
Did some searching and found two more inactive (.nl, .ca) and another active (.eu redirects to https://fuelcelltrucks.eu). The .eu seems like a good outbound prospect.
Looks like it may be closer to $xxxx but the .eu may be willing to go higher.
Edit: I just checked the .eu more closely, and it's more of an informational site, rather than an operating business. So less likely chance for a high sale, especially since they're using it as redirect.
you have a domain that shouldn't even be listed for sale renew for 5 more years and put up a landing page
don't actively reach out to buyers this niche need time to mature (i don't usually throw numbers around but this one in few years i see it going for high xxxx
good luck
