  The transition to a net zero energy system necessitates development in a
number of directions including developing advanced electricity trading markets.
Due to electricity markets being responsible for a large portion of carbon
emissions, improving the electricity markets' method for determining energy
transactions could have a significant impact on carbon reductions and thus
facilitate this transition. V2X technology can be applied to regulate different
energy markets, and thus reduce costs and carbon emissions by using the
batteries in electric vehicles to store energy during off-peak hours and export
it during peak hours.
  We develop a novel contract based on the VCG-mechanism, for exporting and
importing electricity effectively, and show how this mechanism can raise
efficiency, facilitate the development of a sustainable and efficient
electricity market, and bring us nearer to our Net Zero Goal.
