The paper presents an analysis of electricity generation technologies, as well as heat and electricity cogeneration technologies of the future for Polish power system. The analysis focuses on technologies used in three types of power plants: system large power plants, large and medium power CHP plants and small power CHP plants (distributed sources). Individual solutions are characterised by their specifi c CO2 emissions (kg CO2 /kWh) and specifi c electricity generation cost discounted for 2011 with the carbon emission cost included.

W pracy została przedstawiona analiza perspektywicznych technologii wytwarzania energii elektrycznej oraz skojarzonego wytwarzania energii elektrycznej i ciepła dla polskiej elektroenergetyki. Analizę wykonano dla technologii stosowanych w trzech rodzajach źródeł wytwórczych: elektrowni systemowych, elektrociepłowni dużej i średniej mocy oraz elektrowni i elektrociepłowni małej mocy (źródeł rozproszonych). Poszczególne technologie zostały scharakteryzowane przez emisję jednostkową CO2 (kgCO2 /kWh) oraz jednostkowe, zdyskontowane na rok 2011, koszty wytwarzania energii elektrycznej, z uwzględnieniem kosztów emisji CO2.

Purpose: The publication presented is a realistic, one of the practicable idea for a substitute to system power plants, consisting in the construction of combined heat and power plants using renewable resources of geo-plutonic energy. Design/methodology/approach: There are various methods of obtaining geothermal energy and various uses for it. The proposed GEO-PLUTONIC ENERGY represents an endless, renewable source of energy coming from nuclear reaction in the Earth’s nucleus, where the temperature reaches 6,000 Centigrade. Mass production of electricity from the Earth’s heat, possible in Iceland due to the volcanic nature of these resources and the shallow depth at which they occur, was difficult in other countries due to the high cost of drilling to greater depths. This barrier has been overcome by us through using a special horizontal drilling technique. Findings: In order to extract and collect the accumulated energy from the area of a large thermal field, a modified shaft/drilling system (called a Super Daisy System) equipped with a 3D grate of directional bore-holes called Jet-Stingers fitted with multi-functional heat exchangers is used. The emission-free concept of Geo-Plutonic Energy with the temperature of only over 250ºC, from which we can obtain about 30 MPa of pressure on the turbine. With increased the depth the temperature and heat transmissibility will be raised significantly, which can resulted the yield even to 7-10 MWe (of electricity) from one deep heat exchanger. Research limitations/implications: From the rock mass we can collect renewable resources of ,,dry” ascending energy from the paleo heat flow coming from the great atomic furnace – the magma. Originality/value: We are experienced in using the appropriate hydro-thermodynamic theory and its applications which allows us to almost precisely forecast and control the quantity of heat not exceeding 20% of the 100% regeneration capability in the same time range.
