ENEA’s commitment to hydrogen and fuel cells: COMETHY, a new European project %A %B %e%q, %YIn the field of renewable ENEA focuses its research on the following technologies: solar thermodynamic solar photovoltaics Biomass and biofuels Solar heating at low and medium temperature Hydrogen, fuel cells and energy storage systems. ENEA activities in Hydrogen, fuel cells and energy storage systems field are generally aimed at contributing to the development of energy vectors and electrochemical systems for energy conversion and storage. Such systems can reduce energy consumption and emissions in the distributed energy and transport sectors, thus encouraging the latter to benefit from the use of renewables. Compact & Multi-Energy Hydrogen To converter (COMETHY) is one of the projects (started 12.01.2011) FCH-JU-funded under the seventh Framework Programme, ENEA (in collaboration with Israel, Germany, Greece, Netherlands) has conducted. The two years project aims at developing a compact steam reformer to convert reformable fuels (methane, bioethanol, glycerol, etc.) to pure hydrogen, adaptable to several heat sources (solar, biomass, fossil, refuse derived fuels, etc.) depending on the locally available energy mix. The following systems and components will be developed: a structured open-celled catalyst for the low-temperature (< 550°C) steam reforming processes - Reducing reforming temperatures below 550°C by itself will significantly reduce material costs. a membrane reactor to separate hydrogen from the gas mixture the use of an intermediate low-cost and environmentally friendly liquid heat transfer fluid (molten nitrates) to supply process heat from a multi fuel system. The process [...]
