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.</p> 2021-12-28T00:00:00+00:00 Copyright (c) http://pvj.vn/index.php/TCDK/article/view/780 Hydrogen supply chain and production technology 2021-12-29T04:45:55+00:00 Thi Lan Oanh Nguyen oanhnl@vpi.pvn.vn <p>Hydrogen is forecasted as an energy solution for the future thanks to its advantages of cleanliness, abundance and high energy conversion efficiency. The paper briefly introduces the hydrogen supply chain, hydrogen production technologies prevailing or expected in the future, as well as challenges that need to be addressed for a successful transition to a hydrogen-based economy.</p> 2021-12-28T00:00:00+00:00 Copyright (c) http://pvj.vn/index.php/TCDK/article/view/781 Technologies for production of green hydrogen and hydrogen based synthetic fuels 2021-12-29T04:45:55+00:00 Van Nhu Nguyen nguyen3vannhu@yahoo.com Nhu Tung Truong tcdk@pvn.vn <p>Hydrogen is an essential material/fuel for industry and energy conversion. The processes for producing hydrogen depend on the raw materials and energy source used. In terms of climate impacts, the most promising hydrogen production method is water electrolysis. The regenerative electrolysis process depends on the carbon intensity of the electricity and the efficiency of converting that electricity into hydrogen. The development of technologies to extract hydrogen (from conventional and renewable resources) tends to optimise the water electrolysis process using renewable energies by extending material durability, increasing performance efficiency, and reducing precious metal contents in catalysts, thereby lowering the production costs. The article introduces the latest advances in green hydrogen production technologies using renewable energies, particularly focusing on water and seawater electrolysis, combining electrolysis and solar energy as well as hydrogen-based synthetic fuel production, hydrogen production from biomass and biogas.</p> 2021-12-28T00:00:00+00:00 Copyright (c) http://pvj.vn/index.php/TCDK/article/view/782 Potential market and impact of clean hydrogen development to 2050 in Vietnam 2021-12-29T04:45:55+00:00 Huu Luong Nguyen luongnh.pvpro@vpi.pvn.vn <p>Hydrogen plays an important role in the energy transition towards a zero-carbon economy. Blue hydrogen and green hydrogen are potential sources to replace fossil materials and fuels in the fields of refining - petrochemical, production of fertiliser, steel, cement, electricity, and transportation. The potential demand for clean hydrogen in these areas has been evaluated along with the impacts and benefits of hydrogen development. Accordingly, the potential hydrogen market can reach an output of 22 million tons/year by 2050. The development of hydrogen in the fields will create new markets with a total value of USD 100 billion in 2035 and USD 1,200 billion in 2050. In terms of the environment, replacing fossil materials and fuels with hydrogen reduces the total national CO2 emissions by 5.4%. In order to develop and complete the hydrogen value chain in Vietnam, it is necessary to set goals and roadmaps along with appropriate policies. Recognising the importance of hydrogen to the operation of the oil and gas and energy sectors in general, the Vietnam Oil and Gas Group (PVN) has developed a scientific research programme on the development of production, storage, transportation, distribution, and efficient use of hydrogen in Vietnam in the 2021 - 2025 period.</p> 2021-12-28T00:00:00+00:00 Copyright (c) http://pvj.vn/index.php/TCDK/article/view/783 Hydrogen application technologies and environmentally friendly smart energy system 2021-12-29T04:47:09+00:00 Van Nhu Nguyen nguyen3vannhu@yahoo.com Nhu Tung Truong tcdk@pvn.vn Van Thinh Dinh tcdk@pvn.vn Viet Anh Nguyen tcdk@pvn.vn <p>Climate change and fossil fuel depletion are the main reasons for many countries around the world to develop and implement energy transition strategies. Being a very clean burning fuel (generating steam only), hydrogen will play an important role in the transition from fossil energy to CO2-free energy. The paper introduces recent advances of hydrogen technology applied in transportation, industry, and power generation in the world; challenges regarding hydrogen safety and technology; barriers in social perception; and some recommendations for the development of hydrogen technology and environmentally friendly smart energy systems in Vietnam.</p> 2021-12-28T00:00:00+00:00 Copyright (c) http://pvj.vn/index.php/TCDK/article/view/784 Experiences in long-term operation of a green hydrogen production plant using wind power in Germany - a possible model for Vietnam 2021-12-29T04:45:55+00:00 Van Thinh Dinh tdinhvan@web.de <p>Hydrogen is considered as "the green fuel of the 21st century" and forecasted to play a leading role in the energy transition. The article introduces the processes of green hydrogen production in Energiepark Mainz, the first wind power hydrogen production plant with a capacity of 6 MW in Germany. The article describes the production, storage, transportation, and consumption (gas, fuel for bus and industries) of green hydrogen through the continuous operation of the plant. Based on that, the author analyses opportunities and challenges when applying Energiepark Mainz's model to the green hydrogen production strategy in Vietnam.</p> 2021-12-28T00:00:00+00:00 Copyright (c) http://pvj.vn/index.php/TCDK/article/view/785 Objective factors and policies of countries affecting hydrogen market development 2021-12-29T04:45:54+00:00 Ba Nam Pham nampb@vpi.pvn.vn Thi Ngoan Nghiem ngoannt@vpi.pvn.vn Minh Phuong Dao tcdk@pvn.vn Thi Lan Oanh Nguyen tcdk@pvn.vn Hien Trang Ta tcdk@pvn.vn Linh Chi Tran tcdk@pvn.vn <p>By 2050, blue hydrogen (produced by SMR method using CCS technology to capture CO2) will make up about 18% of hydrogen supply, whilst green hydrogen from solar power will account for 16%, from onshore wind power 16% and offshore wind power 9%.
