The principle is to use solar energy, collected on home roofs, which is then used to electrolyze water in order to produce hydrogen and oxygen. These gases are compressed and stored locally to match the gap between supply and demand. Hydrogen and oxygen are filled in adhoc car reservoirs, and subsequently transposed to electricity for fuel cell driven cars. Such a demonstrator system can already be built today; however the economic viability of the project depends on disruptive innovation based upon our capacity to face and resolve very demanding scientific and technical challenges in the years to follow. One of the main issues in this coherent effort is the optimization of the hydrogen production and usage chain. Several major steps, both in science and engineering, are needed to achieve the commercial exploitation of the overall concept.
