Abstract: Carbon-neutral liquid fuels offer the
possibility of decarbonising transport without the
paradigm shifts required by electrification of the
vehicle fleet or conversion to a hydrogen economy.
The paper describes the SOFT concept (Sustainable
Organic Fuels for Transport) in which carbon-neutral
liquid fuels provide a route to avoiding the climate
change and energy security concerns which
currently challenge the transport sector. The lowcarbon-
number alcohols, and, where necessary,
synthetic diesel and kerosene, offer the prospect of
continued high levels of affordable mobility through
the gradual evolution of the vehicle fleet and fuel
distribution infrastructure to one which is broadly
compatible with that which pervades today. Vehicle
technology to support this transition is described.
The production of liquid fuels from air and water are
reviewed in which fully-closed carbon cycles are
theoretically possible with the development of largescale
renewable energy generation and CO2 capture
from the atmosphere. To expedite air capture,
developments in CO2 concentration and release
based on bipolar membrane electrodialysis are
described and initial results from a laboratory-scale
device are reported.
