World Energy Outlook

In this chapter, the correlation of growth in population, economic welfare, and increase in the energy demand is evaluated with examples. The biggest concern of mankind is which sources cover the immense energy demand. It is obvious that fossil fuels are the base energy source, and in order to supply developing energy needs, serious investments are needed in the energy sector. That is why the results of monetary aspects in energy prices and the conditions in leading supplier countries are also evaluated.

Legal Frameworks

This chapter investigates the concept of ‘energy security’, understood as the ‘uninterrupted availability of energy resources at an affordable price’. Importantly, according to this definition, the ‘availability’ of energy resources is measured against existing energy demand, and threats to energy security are therefore threats to the supply of enough energy to meet existing energy demand. Energy supply depends upon both domestic and international factors which are so interconnected that it is difficult to distinguish where one starts and the other ends. What is clear, however, is that international law plays a fundamental role in addressing many threats to energy security. The chapter looks at existing threats to energy security and the international legal frameworks that have been established in response. The challenges to energy security include an exponential increase in world energy demand, shortages of national oil and gas deposits, the need to reduce dependence on fossil fuel production in order to counteract climate change, as well as risks of geopolitical instability. The chapter then focuses on the mechanisms aimed to ensure that the flow of energy remains uninterrupted and at an affordable price, as well as on those mechanisms aimed at increasing access to energy resources.

The Impact

The study of the viability of hydrogen production as a sustainable energy source is a current challenge, to satisfy the great world energy demand. There are several techniques to produce hydrogen, either mature or under development. The election of the hydrogen production method will have a high impact on practical sustainability of the hydrogen economy. An important profile for the viability of a process is the calculation of energy and exergy efficiencies, as well as their overall integration into the circular economy. To carry out theoretical energy and exergy analyses we have estimated proposed hydrogen production using different software (DWSIM and MATLAB) and reference conditions. The analysis consolidates methane reforming or auto-thermal reforming as the viable technologies at the present state of the art, with reasonable energy and exergy efficiencies, but pending on the impact of environmental constraints as CO2 emission countermeasures. However, natural gas or electrolysis show very promising results, and should be advanced in their technological and maturity scaling. Electrolysis shows a very good exergy efficiency due to the fact that electricity itself is a high exergy source. Pyrolysis exergy loses are mostly in the form of solid carbon material, which has a very high integration potential into the hydrogen economy.

Biomass is one of the most promising renewable energy sources. Abundantly, the potential as an alternative source to meet the world energy demand has been widely acknowledged. Gasification is one of the most efficient processes concerning thermochemical conversion, having as objective the production of a gas with useful energy power, known as producer gas. In order to optimize thermochemical processes such as the combustion of gases and subsequent gas mixture, computer modeling is becoming an important tool. Aiming to improve the performance of a combustion chamber, previously coupled to a downdraft gasifier, a thermofluidynamic model was elaborated and validated, using the concepts of computational fluid dynamics (CFD). It was reported that temperature, pressure, and velocity distributions of the computational model showed good consistency with experimental data, which allows using this model to predict the performance of this type of combustion chambers.
