Official Data

Many studies, like the influential BP Statistical Review of World Energy 2004, notice a worlwide growth of oil-reserves. But there are many reasons to mistrust the official data: They use their own questionable definitions of "oil reserves", mixing conventional and unconventional reserves. Moreover the growth of oil-reserves, which is shown in the statistics, is based more or less on a reassesment of the existing but not on a discovery of new oil-fields. Due to these deceptive practices, the "Assosiation for the Study of Peak Oil" has published a new study with the result that it can find only 780 billion barrels of proved oil worldwide, instead of the 1147,7 billion barrels that BP claims in its statistics.

Timur Tengah merupakan penghasil minyak mentah yang sebagian besar pendistribusiannya dilakukan di benua Asia. Berdasarkan data dari BP Statistical Review Of World Energy 2018, konsumsi energi Indonesia meningkat sebesar 5,0%, yaitu 175,2 juta ton, yang merupakan peningkatan terbesar dalam lima tahun terakhir. Konsumsi energi berada di wilayah Jawa dan sekitarnya. PT. Unit Pengilangan Pertamina (RU) IV Cilacap memproses minyak mentah domestik dan impor minyak mentah sebagai bahan baku. Pemrosesan minyak mentah dipengaruhi oleh Gross Profit Worth (GPW) dalam minyak mentah yang diproduksi. GPW pada Agami -7,66 minyak mentah impor pada bulan Januari dan -6,45 pada bulan Februari. Margin diperoleh 1.046,04 pada bulan Januari. Sementara itu, berdasarkan harga minyak yang relatif mahal, maka hal tersebut diatasi dengan proses Blending dilakukan meningkatkan Octane Number (ON) dan mencari minyak mentah alternatif daripada minyak mentah impor. Dan masalah yang dialami pada realita di lapangan yakni kelebihan waktu bongkar muat yang disebut dengan Demurrage. Beberapa faktor di atas menunjukkan bahwa diperlukan  inovasi dalam hal rantai pasokan dan energi alternatif dari penggunaan minyak mentah impor.

Abstract Buildings consume around 40% of total world energy and are responsible for 30-35% greenhouse gas emissions globally. Latent heat thermal energy storage is one of the most promising techniques being investigated currently to reduce the thermal load of buildings. Different types of phase change materials (PCMs) i.e. organic, inorganic and eutectics with different thermophysical properties have been investigated for passive cooling of buildings showing great potential for saving energy. Due to their higher thermal conductivity and high heat storage capacity per unit volume, inorganic phase change materials take advantage over organic ones. They can be used as stand-alone heat storage systems for free cooling, embedded in building walls, windows, roofs and ceilings etc. Studies have shown that there are some drawbacks of inorganic PCMs as well like corrosion of container material, phase separation and supercooling which require solutions.

Nb, Ta and V are prototype substances for the study of the endothermic reactions of H with metals. Such metal-hydrogen reactions have gained increased importance due to the application of metal-hydrides in hydrogen- und heat storage devices. Electron microscopy and diffraction were demonstrated to be excellent methods in the study of hydride morphologies and structures (1). - Figures 1 and 2 show the NbH and TaH phase diagrams (2,3,4). EM techniques have contributed substantially to the elucidation of the structures and domain configurations of phases β, ζ and ε (1,4). Precision length measurement techniques of distances in reciprocal space (5) recently led to a detailed understanding of the distortions of the unit cells of phases ζ and ε (4). In the same work (4) the existence of the new phase η was shown. It is stable near -68 °C. The sequence of transitions is thus below 70 %.
