		global energy demand and as a possible replacement of different conventional energy sources such as coal
		or oil. Knowledge of the fundamental concepts, the methods of analysis of the hydrate cage structures, the
		growing interest of researchers and scientists to find mechanisms of exploitation of these natural resources
		is of relevant importance. The present article shows a comprehensive review of the main concepts of natural
		gas hydrates. The three types of cage structures, sI, sII and sH are defined. A reference about the distribution
		of clathrate hydrates worldwide and the description of the main molecular dynamic simulation algorithms,
		FSICA, CHILL+, GRADE, ICO and HTR that hitherto have been developed is presented. Finally, applications in the fields of energy generation and oil and gas transportation are analyzed providing an overview of the
		trends in the present and future applications of clathrate hydrates. The conclusions of the present work
		emphasize the vast amount of natural gas hydrates worldwide, mentioning it as an advantage to consider

		keletkezik, szén-dioxid nem. Ezt a többletenergiát föld alatti gáztárolókban lehet tárolni, ahová földgázzal keverve szállítják. A gáz- és olajiparban a hidrátkristályok képződése jelentős károkat okozhat. Hatalmas mennyiségű hidrátkristály képződik, ami hidrátdugulásokat okozhat a csővezetékben. A földgázhoz hasonlóan földgáz-hidrogén keverék esetén hidrátképződés megy végbe. A hidrogén, amely vegyületeiben nagy mennyiségben fordul elő a Földön, a jövőben várhatóan ígéretes energiahordozó lesz. A hidrogén energiahordozóként való felhasználása jelentős környezeti előnyökkel jár, hiszen szén-dioxid-mentes energiaellátást ígér. A hidrogéntechnológia elterjedéséhez azonban megoldani kell annak problémás tárolási és szállítási kérdéseit. A hidrogén tárolása és felhasználása során felmerült a lehetőség, hogy a hidrogén földgázzal való keverésével, a meglévő földgázvezetékes tárolók és hálózatok felhasználásával a kevert keverék eljusson a végfelhasználókhoz, ezáltal teljesítménynövekedés érhető el. A cikkben a hidrogén hidrátosodásának egy lehetséges laboroatóriumi vizsgálatát mutatjuk be.},

	abstract = {The primary cause of global warming is the burning of fossil fuels. Therefore, we are looking for alternative solutions for electricity generation, such as the increased use of renewable energies such as solar, wind and hydropower. The main drawback of these energy generation methods is the high degree of weather dependence, highly unbalanced, so the creation of a complex energy storage system is of paramount importance. This system would store the excess energy as a buffer, balancing the periodicity between demand and supply. Hydrogen storage (hydrogen is produced by the electrolysis of water using renewable energy) in the form of clathrate can be one of the possible forms of energy storage. To facilitate hydrogen supply in a future with zero carbon emissions, it is necessary to examine the technical aspects and feasibility of adsorption of hydrogen in high surface area materials. The capturing of molecular hydrogen in a crystalline guest molecule, i.e., water, as a storage method is a relatively new technology. Hydrogen hydrate is a promising medium for hydrogen storage, with advantages such as low production cost, safety, lack of negative environmental effects. The aim of this study is to present the latest developments in hydrogen storage in the form of hydrates and to present the challenges of this research area.},

	abstract = {The lithological interpretation of well logs is a fundamental task in Earth science that can be accomplished with the application of various machine learning algorithms. The current investigation attempts to evaluate the performance of the K-nearest-neighbour Density Estimate (KNN) and K-means cluster analysis methods for predicting lithology in a dataset of logs measured in the siliciclastic reservoir of the Shushufindi Oilfield of Ecuador. The comparison of lithological interpretation is assembled using classical methods, such as qualitative interpretation and density-neutron cross plot. The lithological interpretation results showed that the supervised method KNN has a higher fitting level with the comparison interpretation data (87.3%, 1145 m predicted of 1311.1 m interpreted) than the results of the K-means method (71.6%, 939.7 m predicted of 1311.1 m interpreted). The geological nature of the reservoir creates a level of discrepancy because of the near geophysical responses between limestone and intermedia grain size rocks. The possibility of controlling this in the KNN algorithm makes it preferable for usage in these types of reservoir lithological interpretation},
