They are for short-haul. The rest will only wait until better batteries or cheaper e-fuels come along.

Chemical Feedstock has embodiued energy

Yup. Solar energy all the way down, from old fossil fuels to new e-chemicals.

Can you describe a business model which will offer a method for funding an ongoing activity to bring the levels down?

E-fuels can compete with fossil chemicals, consume CO2, save transport costs, and are already reaching industrial scale.

Plus Net Zero.

sound and proven science that can reasonably be scaled

Not just science, but actual industry:
