Bariery rozwoju rynku sprężonego gazu ziemnego do napędu pojazdów w Polsce
(2009) Kwaśniewski, Krzysztof; Sas, Jan
The forecast for 2020 for the main alternative gas for vehicles estimate the economic (market) potential of fuel produced of bio-mass at 15%, natural gas at 10%, LPG at 5% and hydrogen at a few percent. The development strategies of the NGV market in Europe and in the Asia-Pacific area are completely different. The substitution of fuel oil derivatives in Poland on the estimated level of 2% in 2010 and 5% in 2015 will not be possible to implementation (realization); thus the strategic aims in this area have to be corrected (adjusted). The implementing strategies and costs are the crucial issues at the present stage of the market development in Poland. The solutions of vehicles production and gas compression are the fully developed technology and do not create any operational risk. Based on the European countries experiences we can say that in order to reach the critical mass it is necessary to build in Poland a few hundred CNG gas stations, opened 24 hours. The analysis of operational costs of the best solutions in Poland shows that construction and exploitation of the gas stations can be effective at the 1,35 zł/Nm3 CNG price (for the prices of the first three months); so it guarantees the competitiveness toward the fuel oil derivatives. In that case PGNiG S.A. is obliged to reorientate its strategy of exploitation their CNG gas stations, to standardize the solutions of constructing and equiping as well as the CNG price policy.

Nowe technologie dostaw gazu ziemnego elementem jego dywersyfikacji
(2010) Piwowarski, Andrzej J; Rychlicki, Stanisław
With the present annual consumption of about 14 bm3, not negligible indigenous natural gas reserves (approx. 100 bm3) and long term natural gas supply contract with Gazprom, Poland is quite well endowed with natural gas resources. Nevertheless this apparently comfortable situation doesn't represent sufficient gas supply security especially in the future when the dependency on one main external gas supply source could have been increasing, and when the political factors can disturb the regular gas supply to the country. Since several years there is an intention and concern in Poland to diversify gas supply sources and routes in view of increasing not only gas supply security but also to improve the flexibility of gas transmission system, to deserve zones not supplied with gas, and to find less costly gas. Several options of gas supply diversification have been envisaged until now including off shore gas pipelines from Denmark and Norway but for various reasons political and economic couldn't be implemented until now. Some years ago LNG project has also arisen. Some troubles, but not really important in the Russian gas supplies throughout Belarus, and Ukraine occurred in the past, becoming an additional signal to intensify the search for a new solutions to enhance the gas supply security. Among several solutions the choice has been made for the shipping natural gas mainly from the North and Norwegian Sea Region to the Polish gas market using an innovative CNG sea transport technology developed in Norway, Canada, and in USA"," this solution is being perceived as the most feasible and most interesting from the point of view of the flexibility, security, relatively modest investment costs, rapidity (short time of implementation), and good gas price, especially for gas from so called mature areas. However, an alternative solution to diversify gas supply to Poland remains LNG, when we have started with the project of LNG receiving terminal in North-Western part of the country (near Szczecin), which is expected to be operational in the middle of 2014 year. Another solution, that we are envisaging, constitutes the use of the new technology of gas supply i.e. LNG regasified on the LNG tanker offshore or onshore or regasified on the Floating Storage Regasification Unit - FSRU, which can be a cheap, second hand LNG carrier or a barge. The Regas LNG can be sent directly to the high pressure gas pipeline onshore"," this solution is called alongside ship moored. We are taking into consideration two from four existing technologies of Regas LNG: (i) Energy Bridge Regasification Vessel - EBRV TM - owned by the American company, Energy Excelerate from Houston, and the Norwegian technology represented by Hoegh LNG company.

Technological and safety aspects of CNG home fast refueling units
(2016) Kuczyński, Szymon; Liszka, Krystian; Łaciak, Mariusz; Olìjnik, Andrìj; Strods, Robert; Szurlej, Adam
Despite all global economic shifts and the fact that natural gas is recognized worldwide as the main and the leading alternative to oil products in transportation sector, there is a huge barrier to switch passenger vehicle segment to natural gas – the lack of refueling infrastructure for natural gas vehicles. The key to solving that problem and providing barrier breaking refueling infrastructure solution for natural gas vehicles (NGV) is home fast refueling units. It operates using natural gas (methane), which is being provided through gas pipelines at client’s home, and electricity connection point. It enables an environmentally friendly NGV’s home refueling just in minutes. The underlying technology is one stage hydraulic compressor (instead of multistage mechanical compressor technology) which provides the possibility to compress low pressure gas from residential gas grid to 200 bar for its further usage as a fuel for NGVs. More than efficiency and convenience, the direct hydraulic compressor technology provides compelling cost and lifetime advantages as well as superior convenience over other solutions. Aims of this article is to compare technical, technological and safety aspects of home refueling units and estimate a perspectives of natural gas vehicles as an alternative for regular vehicles.
