educing human Carbon (CO2) Emissions is a worldwide. Therefore there is a lot of interest for the use of advanced low
CO2 emission fuels such as biofuels and for the introduction of battery powered electrical vehicles charged by renewable
energy such as solar, wind, hydro or geothermal power. Lesser known is the concept of converting the power generated
by renewable energy directly into zero carbon emissions fuels, also sometimes called “electrical-fuels”. It appears that
this option may become the fastest and lowest cost transition path to Zero Carbon emissions. The technology to do so is
already available and in fact state-of-the art except for the step to economically harvest CO2 (and water) directly from the
air. Direct Air Capture (DAC) of CO2 will be necessary as in many cases no secure CO2 point sources are present or will be
present in the future at the locations where the lowest cost electricity (to produce Hydrogen) is available. Furthermore it
may be prudent not to rely too much on CO2 point sources of fossil origin to produce zero carbon emissions fuels. ANTECY
has developed the crucial technology which still was the missing link to making this possible. Carbon dioxide (CO2) is
captured from Air and/or existing CO2 containing gas streams and concentrated to high purity and pressure in order to be
converted into liquid hydrocarbons with Hydrogen (H2) produced by water-splitting making use of renewable electricity.
The unique enabling features of this technology are that it is low cost, requires a low amount of low value heat and above
all that it makes use of an environmentally friendly and robust non-toxic solid sorbent system based on Carbonates.
