Renewable and Sustainable Energy Reviews | Year: 2017
In 2012 the Hungarian Government has decided to revise the country's National Renewable Action Plan, mostly due to the experienced changes of the economic environment and the continuously decreasing cost of renewable energy technologies. Present paper introduces the methodology and the most important results of this revision process, carried out by the Centre for Energy Research of the Hungarian Academy of Sciences. First the results of Hungarian initiatives, aiming the increase of the share of renewable, were examined, then by analysis of technological and economic trends of recent years, new scenarios were set to reach the targets set by adopting the 2009/28/EC directive.  A multiple-criteria decision analysis (MCDA) of all potential renewable technologies and their respective fuels served as a basis for the most competitive scenarios. The authors focused on five aspects: economy, environment, climate, job creation and innovation. Due to coverage constraints, present paper dominantly focuses on the review of the economical aspect, but in addition to those mentioned, further aspects may also be considered in the optimisation process. The results of the revision highlight that by 2020 Hungary will still mostly be using bioenergy in its renewable portfolio, which also allows the country to exploit its significant potential. © 2017 Elsevier Ltd

Giant incised canyons were recently recognized in Late-Miocene post-rift sediments in the central part of the Pannonian Basin. Though not connected to the world seas, Lake Pannon shows significant signs of relative lake level variations controlled by tectonics and climate changes. The incision surface of the Alpar canyon system is connected to SB Pa-4 (6.8 Ma sensu Vakarcs, 1997), earlier reported to represent a significant relative base-level fall in the basin, however, debated recently. Incised several hundred meters in the preexisting substrate, the individual canyon valleys of the Alpar canyon system are enormous in size and display a multi-story nature. They loose topographic expression headwards and basinward. Widths of individual valleys range from 5 to 10 km, with smaller tributaries. In the study area several adjacent canyon valleys can be seen on seismic profiles. The valley depth is greatest near their confluence, where a major trunk valley (600-700 m deep) was formed by eroding most of the Upper Miocene succession. The canyons are filled with clay marls. They are incised into an extremely thick aggrading deltaic complex and are overlain by fluvial sediments, suggesting a major transgression in between. The Late Miocene Alpár canyon system developed on the southern margin of the Mid-Hungarian Mobile Belt, the latter is characterized by NE-SW oriented fold axis and NE-SW oriented left lateral strike-slip faults. The canyon system coincides with a large releasing bend and/or extensional duplex of the Paks-Szolnok strike-slip system being active as sinistral during the Late Miocene. Presumably, the formation of the deep canyons was generated by the close interaction of several factors and events in space and time, among them tectonic uplift forced relative base-level fall, the reactivation and bending/duplexing of a strike-slip fault system located near the coeval zone of the lake shoreline and shelf edge, and the possible change of sediment supply carried by overfed rivers. © 2012 Elsevier B.V.

In Kurdistan Region of Iraq, the southern front of the Zagros fold belt is expressed by a series of folds trending NW-SE and E-W. Previously the existence of a main frontal thrust was suggested based on sharp topographic breaks along the frontal anticlines. Field mapping, structural analysis of seismic sections and wells revealed that these fold trains are affected by conjugate reverse faulting. Some minor portions of this thrusting can be mapped on the surface, sometimes combined with left-lateral strike slip movement. These thrusts link several detachments, some of which can be observed also on the surface. No expressed main boundary thrust was found, but such structures might be present at deep detachment level.

Two types of biodegradable hydraulic fluids (HEES and HEPR) with the mineral oil-based hydraulic fluid (HV) were compared. The tests were performed using a test bench. During the tests with a tractor hydraulic pump, the fluids were loaded by a cyclic pressure load. The tests of fluids were evaluated on the basis of wear of the pump. Evaluation parameters were the flow characteristics of the pump and the cleanliness level of tested fluids. The temperature of the fluid under which the test was performed was measured in real operating conditions of the Zetor Forterra 11441 tractor. It is possible to state upon the test results that the mineral oil-based fluid was classified in the first place, the biodegradable fluid of the HEPR type in the second place, and the biodegradable fluid of the HEES type received the last position.

The effect of CO2 enrichment on the rate of photosynthesis and the water use efficiency (WUE) of young pepper and tomato plants was studied in the phytotron. A CO2 level of 1000 ppm significantly increased the net assimilation rate in the upper foliage, while the increase was even more considerable in the lower layers of the canopy, with values of up to 100%. The 1500 ppm CO2 level caused a further substantial increase in CO2 assimilation and at least doubled (in tomato) or tripled (in pepper) the water use efficiency on a leaf area basis compared to the ambient values. Although the response in terms of photosynthesis and WUE was not variety-specific, there were differences between the pepper hybrids in the biomass components, exceeding 100% for the total biomass at the 1500 ppm CO2 level. In tomato, however, there was no significant variation in the total biomass of the three hybrids investigated in this early phase of development at either CO2 level.

BUDAPEST, 13-Feb-2017 — /EuropaWire/ — MOL Group expanded its exploration portfolio by acquiring new licenses in Hungary and Norway. MOL acquired 6 new licences in the 4th bid round in Hungary, doubling its exploration acreage in the country. MOL Norge participated in the latest APA licensing round and acquired 4 licences in the Norwegian Continental Shelf, one of which with operatorship. These successes significantly contribute to the implementation of the MOL 2030 strategy. MOL has won 6 new licences in the fourth Hungarian hydrocarbon exploration tender and the concession contracts have been signed by the representatives of the Ministry of National Development and MOL. As a result MOL can start hydrocarbon exploration on nearly 4,200 square kilometres in the area of Bázakerettye, Bucsa, Jászárokszállás, Mezőtúr, Okány-West and Zala-West in addition to the almost 4,200 square kilometres area covered by mining authority decisions and concessions already acquired. MOL is targeting both proven exploration plays in Hungary as well as new plays which are the result of our ongoing new Trans-Pannonian basin study. Separately, it was announced earlier that the Norwegian Ministry of Petroleum and Energy granted four licences to MOL Norge on the Norwegian Continental Shelf at the 2016 APA (Award in Pre-Defined Areas) licensing round, including one with operatorship. MOL has been granted operatorship in an additional position in the Mandal High Area, one of MOL Norge’s core areas in Norway. The partners in the new operated licence include Statoil and Petoro AS, the leading national oil and gas companies in Norway. MOL has also successfully joined three licenses operated by AkerBP. „We are very happy that we have successfully competed in the latest bid rounds in two of our core countries doubling our exploration footprint in Hungary and adding exciting prospects in Norway with worldclass partners. I am confident that the expansion of our Central Eastern European and Norwegian exploration portfolio will support the delivery of organic reserve replacement for the Group.”
