The topic investigated in this article is a comparison contrast and integration effort of European strategies for sustainable development with the evolving market initiatives that are beginning to fuel the fourth industrial revolution. Several regulatory initiatives from continental bodies come into effect to radically change access to finances for business development based on sustainability goals and an analysis of the legislation and trends becomes essential Read More

Taking into account the international policies in the field of environmental protection in the world in general and in the European Union in particular the reduction of greenhouse gas (GHG) emissions and primarily of carbon dioxide has become one of the most important objectives. This can be obtained through various renewable energy sources and non-polluting technologies such as the mixing of hydrogen and natural gas. Combining hydrogen w Read More

Hydrogen (H2 ) is the most abundant element in the universe and it is also a neutral energy carrier meaning the environmental effects of using it are strictly related to the effects of creating the means of producing of that amount of Hydrogen. So far the H2 generation by water electrolysis research field did not manage to break the efficiency barrier in order to consider H2 production as a technology that sustains financially its self-development. However Read More

The increase in greenhouse gas emissions as well as the risk of fossil fuel depletion has prompted a transition to electric transportation. The European Union aims to substantially reduce pollutant emissions by 2035 through the use of renewable energies. In aviation this transition is particularly challenging mainly due to the weight of onboard equipment. Traditional electric motors with radial magnetic flux have been replaced by axial magnetic flux motors wi Read More

During the last few years electric and hydrogen vehicles have become an alternative to cars that use internal combustion engines. The number of electric and hydrogen vehicles sold has increased due to support from local governments and because car manufacturers will stop the production of internal combustion engines in the near future. The emissions of these vehicles while being driven are zero but they still have an impact on the environme Read More

In Spain the institutional framework for photovoltaic energy production has experienced distinct stages. From 2007 to 2012 the feed-in-tariff system led to high annual growth rates of this renewable energy but after the suppression of the policy of public subsidies the sector stagnated. In recent years green hydrogen an innocuous gas in the atmosphere has become a driving force that stimulates photovoltaic energy production. Since 2020 encourage Read More

The increase in demand and thus the need to lower its price has kept C-based fuels as the main source. In this context the use of oil and gas has led to increased climate change resulting in greenhouse gases. The high percentage of emissions over 40% is due to the production of electricity heat or/and energy transport. This is the main reason for global warming and the extreme and increasingly common climate change occurrences with all of n Read More

The analysis aims to determine the most efficient and cost-effective way of providing power to a remote site. The two primary sources of power being considered are photovoltaics and small wind turbines while the two potential storage media are a battery bank and a hydrogen storage fuel cell system. Subsequently the hydrogen is stored within a reservoir and employed as required by the fuel cell. This strategy offers a solution for retaining surpl Read More

Green hydrogen has become a central topic in discussions about the global energy transition seen as a promising solution for decarbonizing economies and meeting climate goals. As part of the process of decarbonization green hydrogen can replace fossil fuels currently in use helping to reduce emissions in sectors vital to the global economy such as industry and transport as well as in the power and heat sectors. Whilst there is significant potential for Read More

The article examines the role of green hydrogen in reducing CO2 emissions in the transition to climate neutrality highlighting both its benefits and challenges. It starts by discussing the production of green hydrogen from renewable sources and provides a brief analysis of primary resource structures for energy production in European countries including Romania. Despite progress there remains a significant reliance on fossil fuels in some countries. Econo Read More
