Abundant Element

Hydrogen, accounting for 75% of ordinary matter by mass and over 90% by atomic number, is the third most abundant element on the Earth's surface, mainly in the form of chemical compounds such as water and hydrocarbons. When burned, hydrogen gas (H2) produces heat and water without causing environmental pollution, thus it is expected to be one of the clean energy sources for the future. Industrial hydrogen has so far been mainly produced by thermochemical processes of fossil fuels such as coal and natural gas, and insignificantly by electrolysis of water. Recent natural hydrogen discoveries recorded in the world, especially the exploration and discovery of relatively pure underground hydrogen which was extracted and used as fuel for a local power generator in Bourakebougou (Mali), show the possibility of prospecting for underground natural hydrogen. The article provides an overview of natural hydrogen discoveries over the world and gives recommendations on the prospecting for underground natural hydrogen in Vietnam.

And Performance

While our planet is rapidly approaching an environmental crisis under the dominant use of depleting fossil fuels, the need for exploiting all forms of new, small carbon foot-print, renewable, and clean energy resources are increasing in the same proportion. Therefore, the need for exploring all types of clean energy resources that the world has- some of which might have not attracted sufficient attention before- is essential in order to implement sufficient, efficient, and widely use all them. In this respect, operational effectiveness of the wind and hydrokinetic turbines depend on the performance of the airfoils chosen. Using double-blade airfoils in the wind and hydrokinetic turbines, minimum wind and hydrokinetic flow velocities to produce meaningful and practical mechanical power reduces to 3- 4 m /s for wind turbines and 1-1.5 m/s or less for hydrokinetic turbines. Consequently, double-blade hydrofoils may re-define the potentials of wind power and hydrokinetic power of the countries in positive manner.

The Impact

Access to energy is crucial in tackling many of the current global development challenges that impact on people’s economic, health and social well-being as well as the ability to meet the commitments of reducing carbon emissions through clean energy use. Despite increased attention from multiple governments and agencies, energy poverty remains a serious sustainable development issue in many developing countries. To date, most research have focused on general access to electricity and the generation of clean energy to replace fossil fuels, failing to address the lack of basic access to clean energy for cooking and heating. More people in the world lack access to clean cooking fuels than to electricity. This issue is one aspect of a broader research which investigates the impacts of optimized energy policy and energy business models on sustainable development in developing countries.

The discovery of oil in Pennsylvania in 1859 was a relatively inconspicuous precursor to what would become an epic shift into the modern age of energy. At the time, the search for “rock oil” was driven by a perception that lighting fuel was running out. Advances in petrochemical refining and internal combustion engines had yet to occur, and oil was more expensive than coal. In less than 100 years, oil gained worldwide prominence as an energy source and traded commodity. Along similar lines, electricity in the early 1900s powered less than 10% of the homes in the United States. Yet, in under a half a century, billions of homes around the world were equipped to utilize the refined form of energy. Estimates indicate that roughly 85% of the world’s population had access to electricity in 2014 (World Bank, n.d.b). For both petroleum and electricity, significant changes in energy use and associated technologies were closely linked to evolutions in infrastructure, institutions, investment, and practices. Today, countless decision-makers are focusing on transforming energy systems from fossil fuels to low carbon energy which is widely deemed to be a cleaner, more sustainable form of energy. As of 2016, 176 countries have renewable energy targets in place, compared to 43 in 2005 (Renewable Energy Policy Network for the 21st Century [REN21], 2017). Many jurisdictions are also setting increasingly ambitious targets for 100% renewable energy or electricity (Bloomberg New Energy Finance [BNEF], 2016). In 2015, the G7 and G20 committed to accelerate the provision of access to renewables and efficiency (REN21, 2016). In conjunction with all of the above priorities, clean energy investment surged in 2015 to a new record of $329 billion, despite low, fossil fuel prices. A significant “decoupling” of economic and carbon dioxide (CO2) growth was also evident, due in part to China’s increased use of renewable energy and efforts by member countries of the Organization for Economic Cooperation and Development (OECD) to foster greater use of renewables and efficiency (REN21, 2016).

The Future

As we enter the new century, new fuels may be required for both stationary power and transportation to ameliorate the triple threats of local air pollution, global climate change and dependence on unstable nations for imported oil. Shifting away from fossil fuels may be essential within decades if citizens in the developing world achieve even a significant fraction of the per capita energy consumption enjoyed by the industrial nations. Business-as-usual or evolutionary shifts in energy consumption patterns may not be adequate. New paradigms and new energy initiatives may be required to protect the environment while providing the energy services we have come to expect. Hydrogen could play a significant role as a clean energy carrier in the future for both stationary and transportation markets. Produced from renewable energy or nuclear power, hydrogen could become the backbone of a truly sustainable energy future – an energy system that consumes no non-renewable resources and creates no pollution or greenhouse gases of any type during operation. However, to achieve this potential, hydrogen must overcome serious economic, technological and safety perception barriers before it can displace fossil fuels as the primary energy carrier throughout the world. In this paper we explore the current status of hydrogen and fuel cell systems compared to other fuel options for reducing pollution, greenhouse gas emissions and suggest the introduction of hydrogen into the energy economy.

Nuclear power is a young technology that has developed within a political environment of ever-changing priorities. In the United Kingdom, Government-led central planning of electricity supply has given way to market forces and the future of nuclear power depends on its ability to compete in this competitive environment as well as its wider public acceptance. In only three years, the disciplines of private sector competition have transformed the economics of United Kingdom nuclear operations and the new generation of pressurized water reactor (PWR) at Sizewell is set to lead the world in safety and performance. Taken together with the growing recognition of the need to protect the local and global environment from the products of the combustion of fossil fuels, the prospects for the future of nuclear power as the major clean energy source for the twenty-first century have never been better.

Biofuels are viewed as a possible fuel of the future. Concerning energy for cars there is intense “competition” stemming from electricity and rising in popularity due to modern research is also hydrogen. In general, biofuels are nowadays strongly supported in the European Union as well as in the United States of America and many other regions of the world. Active management in the oil and gas industry needs to take in account knowledge not only about fossil fuels but also various types of alternative fuels like biofuels. This thesis goal is to analyze the economics of producing Bio-Crude oil from a plant called Jatrophae curcadis, (or also known as “purging nut”). It is nowadays growing around subtropical regions of the North American continent, especially in Mexico, and southern Asia, and with lower yield can grow even in arid wastelands of Central Asia (in arid Mali it is grown to hold wildlife from plants). It is the very undemanding plant so the biofuel produced from it can be very cheap compared to other biofuels. The oil produced from this plant is not being traded on commodities markets yet but is viewed as biofuel of the future as currently sold soybean oil and palm oil are according to my analysis more expensive in many areas of the world. Production of the plant seeds (nuts) when pressed leads to bio-crude oil which can be processed to biocrude. Economic analysis showed that given irrigation and good genetic selection of the plants to give higher production of seeds (price of the kg would be determining factor), the biocrude produced from the seeds has the potential to successfully compete with alternative fuels made from soybean or palm oils.
