The Thesis examines the role of incentives, as means of promotion, with regards to their connection with Battery-Electric-Vehicles sales and electric-Mobility growth worldwide. Economic incentives, such as exemptions from purchase tax and VAT among others are discussed and considered strong encouragements and crucial for promoting the purchase and ownership of BEVs. Apart from fiscal and non-fiscal incentives that are typically introduced by countries and are mostly related to purchase incentives such as subsidies, tax benefits and exemptions, infrastructure promotion measures, traffic regulations and other benefits such as free parking, the Thesis evaluates the revolutionary Vehicle-To-Grid technology and its concept applications with the possibility of becoming a motivating factor which could increase the share of BEVs in transportation sector. The V2G concept allows BEV owners to make a profit from owning a BEV while it is connected to the power grid. A sociotechnical analysis of e-Mobility and V2G technology along with a SWOT analysis of e-Mobility in Attica, Greece are performed. The Thesis concludes that the V2G concept, already applied by several countries, apart from the technological challenges it has to overcome, comprises an incentive that could assist in the rapid growth of BEVs, create new business and employment opportunities, promote innovation and partnerships, benefit public health and the environment.
