Solar-hydrogen energy storage for enabling Qatar solar-grid integration and eco-friendly transportation.

Qatar has drawn up an ambitious plan to install 1.8 GW of solar capacity by 2020. In the transport sector, green hydrogen produced from solar PV offers one of the best opportunities to reduce greenhouse gas emissions and significantly reduce dependence on fossil fuels. Use of zero carbon or ‘green’ hydrogen derived from renewable sources in Fuel Cell Electric Vehicles (FCEV) is expected to lead to a 90%-95% reduction in well-to-wheel emissions by 2020 when compared to existing internal combustion engines. In addition, from 2015, forecasts suggest 57,000 FCEVs will be sold annually with sales volume progressively increasing to 390,000 vehicles annually by 2020
