Résumé

The author elaborated recently the Mother & Father Hybrid Compression Technology, M&FHC. So far, a power cycle plant produced mechanical work exclusively by having the ambient temperature heat source as sink source and a higher temperature than the sink source as heat source. Such a plant named (super-) ambient power plant or AP plant, e.g. Rankine and Rankine-Gas Turbine plants. Unlike AP, M&FHC emphasizes a new concept of power plants, capable to produce mechanical work by using the ambient temperature source as heat source and an artificially created source, of temperature below that of the ambient temperature, as sink source. Such plant named sub-ambient power plant, or SAP plant. Except the hydro-power, wind-and wave-farms and possibly other few small clean power technologies, all the AP plants producing world major power base on operation of (bottoming) steam Rankine cycle (SRC), supplied by fossil or non-pollutant fuels. Roughly, the SRC plants condensers evacuate to ambient sink a huge quantity of heat, equal approximately to the power produced. Most people involved in energy consider planet global warming is the result of CO2 pollution caused by SRC plants burning fossil fuels. This picture is not realistic to a good extent. Indeed, a large plant category are considered “nonpolluting” because do not burn hydrocarbon fuels. To this category belong e.g. the actual Rankine plants powered by nuclear, biomass burning, or future fusion technology. However, they pollute the planet simply by rejecting in the atmosphere the condensing heat we mentioned earlier. The energy involved people attempt to solve the global warming replacing CO2 polluting plants with as much as more power plants belonging to the “nonpolluting” category, but this is far from being the solution. Indeed, first, because the hydrocarbon burning plants are most efficient and second, these plants are replaced by less efficient plants, which heat rejection of in the ambient could be even more pollutant, because CO2 is blocking in global warming all the Earth natural cooling channels. Because the global warming evolves quickly, we must find rapidly a realistic solution. The solution could come from the introduction of the SAP technology. The author proposed lately for the first time an AP & SAP energetic coupling. The AP can be either of “nonpolluting” or polluting type. The AP & SAP coupling applies until SAP replaces the AP in most possible applications. In the AP & SAP synergy, SAP recovers as heat source the condensing heat rejected by AP to ambient sink, of ambient temperature. The work presents theoretical considerations and model outputs of AP&SAP synergy for M&FHC, M&FHC-MORROW and M&FHC-CBS based SAP’s and four SRC based AP plants powered by nuclear, biomass and fuel of hydrocarbon nature, or coming from the future fusion. Ranking AP&SAP synergies efficiency, the first place occupies that using the M&FHC-MORROW SAP with highest efficiency, followed by that using the M&FHC SAP and in the last place that using the M&FHC-CBS SAP. Concerning the synergy complexity, the synergy using the M&FHC SAP occupies the first place, with most reduced complexity, followed by M&FHC-CBS SAP and M&FHC-MORROW SAP in the last place.
