The objective of this project is to provide a means of renewable hydrogen based fuel utilization. The development of a high efficiency, low emissions electrical generator will lead to establishing a path for renewable hydrogen based fuel utilization. The electrical generator is based on developed internal combustion engine technology. It is able to operate on many hydrogen-containing fuels. The efficiency and emissions are comparable to fuel cells (50% fuel to electricity, ~ 0 NOx). This electrical generator is applicable to both stationary power and hybrid vehicles. It also allows specific markets to utilize hydrogen economically and painlessly. The incentives for a hydrogen economy are the emissions, the potentially CO-free use, the sustainability and the energy security. In this paper the focus is on the use of hydrogen in internal combustion engines (ICE), or more precisely, hydrogen fuelled spark ignition (SI) engines. Currently the hydrogen production is the cheapest through the steam reforming of methane, but CO2 emissions cannot be avoided. Renewable energy, e.g. solar power, hydroelectric, tidal etc., can give " CO2 free " electricity to electrolyze water to hydrogen. The downside is that these electricity costs are mostly expensive. Other possibilities are solar thermal, biomass, bacterial etc. Several solutions are possible for the hydrogen storage. Liquid storage gives a high mass density but asks a high energy demand. Mostly used is the compressed storage, vessels with a compression pressure of 350 bar are mentholated and up to 700 bar are demonstrated.
