TY - JOUR N2 - Increasing the share of energy production from renewable sources (RES) plays a key role in the sustainable and more competitive development of the energy sector. Among the renewable energy sources, the greatest increase can be observed in the case of solar and wind power generation. It should be noted that RES are an increasingly important elements of the power systems and that their share in energy production will continue to rise. On the other hand the development of variable generation sources (wind and solar energy) poses a serious challenge for power systems as operators of unconventional power plants are unable to provide information about the forecasted production level and the energy generated in a given period is sometimes higher than the demand for energy in all of the power systems. Therefore, with the development of RES, a considerable amount of the generated energy is wasted. The solution is energy storage, which makes it possible to improve the management of power systems. The objective of this article is to present the concept of electricity storage in the form of the chemical energy of hydrogen (Power to Gas) in order to improve the functioning of the power system in Poland. The expected growth in the installed capacity of wind power plants will result in more periods in which excess energy will be produced. In order to avoid wasting large amounts of energy, the introduction of storage systems is necessary. An analysis of the development of wind power plants demonstrates that the Power to Gas concept can be developed in Poland, as indicated by the estimated installed capacity and the potential amount of energy to be generated. In view of the above, the excess electricity will be available for storage in the form of chemical energy of hydrogen, which L1 - http://journals.pan.pl/Content/108653/PDF/03-Komorowska-Gawlik.pdf L2 - http://journals.pan.pl/Content/108653 PY - 2018 IS - No 4 EP - 43–64 DO - 10.24425/124511 KW - wind energy KW - Power to Gas technology KW - energy storage A1 - Komorowska, Aleksandra A1 - Gawlik, Lidia PB - Instytut Gospodarki Surowcami Mineralnymi i Energią PAN VL - vol. 21 DA - 2018.12.20 T1 - Management of surplus electricity production from unstable renewable energy sources using Power to Gas technology SP - 43–64 UR - http://journals.pan.pl/dlibra/publication/edition/108653 T2 - Polityka Energetyczna - Energy Policy Journal ER -
