This is about Titan Forge, making methanol fuel from solar power. See https://www.biofuelsdigest.com/bdigest/prometheus-fuels-reaches-trl-9-with-titan-forge-alpha-prototype/ https://www.biofuelsdigest.com/bdigest/prometheus-fuels-reac... for example. There are no information about cost, so I suspect it is quite high.
