Tässä vielä kiinnostuneille äärimmäisen hyvä ja ytimekäs lausunto asiantuntijan suusta biopolttoaineiden ja e-fuelin tulevaisuudesta.
TL&DR Summary: we’ll need biofuels for shipping and aviation, which need rather than merely want liquid fuels. We’ll also potentially need biofuels to serve as our reservoir of stored fuels to serve periods of renewable electricity drought and to respond to other emergencies. While these fuels are absolutely possible to produce in the quantities required, they will at scale represent quite a high cost per tonne of net CO2e emissions averted. They are with certainty going to be cheaper at scale than any fuel made from its combustion products using electricity. While some hydrogen will be needed to deoxygenate biofuels, so-called e-fuels are thermodynamic and hence economic nonsense, so we’d better hope we don’t need them.
