Advancing Heat Pumping Technologies: A Key To Europe’s Energy Transition
Characteristic newspapers represent the most advanced research with significant potential for high impact in this area. Characteristic work must be a considerable original item that includes some techniques or access, offers a perspective for future search guidelines and describes potential search applications.
Characteristic newspapers are presented with an individual invitation or recommendation from scientific editors and must receive positive reactions from reviewers.
The articles of the editor’s choice are based on recommendations from scientific editors from around the world. Editors choose a small number of articles recently published in the newspaper, which they believe they will be particularly interesting for readers, or important in the research field. The goal is to provide an image of some of the most interesting works published in various fields of journal research.

Innovation Needs In The Sustainable Development Scenario

Hydrogen fuel cells are successfully used to partially replace internal burning push systems. To this end, the article presents an operational analysis of the energy flow along with an analysis of individual energy transmission systems. Two generations of Toyota Mirai have been used for tests. Operational analysis was performed on the same route (in accordance with RDE -test requirements), assessing the operation of the system in three driving sections (urban, rural and highway). Both generations of the machine system with fuel cells are completely different, which affects the results of the operation of single systems obtained as well as the total flow of energy. The research was done in the flow of energy in the fuel cells, the FC Converter, the battery and the electric motor using a dedicated purchase system. The trials were conducted on the energy of the fuels, the battery energy and the recovered braking energy. It has been discovered that in the section of the second generation city machine (due to its much larger mass), a slightly higher value of energy consumption (with about 2%) was obtained. However, in the remaining stages of the test, the consumption was lower (the maximum difference was 18% in the rural phase). Overall energy consumption in the research test was 19.64 kWh/100 km for the first generation system compared to 18.53 kWh/100 km for the second -generation system. Considering the growth of the mass of the second -generation vehicle resulted in significantly higher benefits in the second -generation car (up to 37% in single sections of the car and about 28% across the car test).
Modern dismissal emission limits mean that new, alternative travel sources require. A dozen or more years ago, natural gas provided hope to reduce discharge emissions and reduce carbon dioxide emissions. However, fuel was made, which only reduces the emissions of carbon dioxide. Currently hydrogen fuel is fuel -technology faster with minimal emissions of discharge and low CO
Emissions [1]. Its use is now possible in both internal burning engines [2] and in fuel cells [3, 4]. Although internal burning engines have been on the market for many years, their overall efficiency remains lower than that of a burning cell stack [5]. However, technological costs are much higher for current generations of fuel cells. However, they are much more often perceived as vehicle push systems that will take place over the next few years (excluding electric vehicles).
Direct Thermochemical Liquefaction
Ongoing development of fuel cell drives requires their further analysis and development. Tree cells (proton exchange membrane) are used in such vehicles. However, the batteries already have a varied design (Nickel-Metal-Ni-MH or Lithium-Jon-Li-Jon) design. The electrical capacity depends on the type of storage systems used. The need to optimize them makes it necessary to test such disks in different operating conditions. Typical tests (homologous tests) are used very often, but the tests under typical real traffic conditions are even greater due to the greater durability with the driver’s directing style. Current work deals with the energy flow assessment in hydrogen push.
In recent years, they have made great progress in hydrogen in the economic and energy strategies of many countries around the world. Hydrogen’s growing interest as fuel should be associated with increasing demands due to climate change, setting high goals to minimize air pollution and its main advantage: zero emissions. Hydrogen is also a reversible energy carrier and can be used for energy conservation, which is particularly important when trying to create a distributed power grid, which depends much on renewable energy sources. For this – above reasons, it has the opportunity to play an important role in the transformation of energy and decrease many sectors – energy, heating, heavy industry and transportation.
However, one of the main challenges facing representatives of various industries is the maturity and availability of various hydrogen -based technologies as a means of achieving a neutral environmental impact. However, as the International Energy Agency estimates, currently only about 30% of the technologies in operation needed to achieve climate neutrality are mature and ready. The remaining 70% are a technology still in prototype or displaying stages, which have not yet been implemented to a considerable degree [6]. This is why it is interesting to look at the estimate of the readiness of hydrogen technologies, including their transportation applications.
It means that the so -called levels of learning will determine the convergent rhythm to highly effective technologies ready to serve the hydrogen economy. While the passenger car market is traditionally seen as an innovative industry, it can also promote many spreads in other industries. In this context, it would be worth rating what is the current level of technical readiness of hydrogen technologies in automotive transport and what the estimated level of learning for an integrated hydrogen -technology system, the hydrogen machine.
Progress In Hydrogen Technology Is Encouraging
Based on the original and unique research conducted as a backdrop of the Polish hydrogen strategy, we used TRL classifications (technology levels) and CRI (commercial index) to evaluate the level of development and implementation of hydrogen technologies. The first of them, developed in the 1970s by NASA, allows the evaluation of the maturity of technology for its commercial application, assessing its development of TRL 1, basic research, on TRL 9, technology demonstrated in actual conditions. The second classification method is about implementing technology in the market, considering the number and variety of its applications. CRI -Scale is extended between the value of CRI 1, which implies the possibility of hypothetical use of technology, and CRI 6, which means it the financial institution. The CRI classification has been applied by the Australian Renewable Energy Agency (Arena) to implement public support for specific technologies.
Both of these classifications, TRL and CRI, are increasingly used in literature as complementary methods of maturity and evaluating the distribution of technology, including low and zero emission technologies [7, 8, 9] – Figure 1.
An analysis that determines the basis of knowledge made for the Polish hydrogen strategy, provided the research results presented below. The research process was conducted in April and May 2021 and consisted of steps including extensive consultations with stakeholders in specialist experience panels. The study, in its field, covered all the elements of the hydrogen -economy chain – production, storage, transport, distribution and use of hydrogen. However, as this article focuses on transport and mobility problems, the results cited TRL and CRI have been selectively evaluated for the use of hydrogen in various transportation modes.
When asked about the total level of hydrogen technologies available in the world, experts have shown that among the solutions mentioned in the field of transportation applications, the highest level of TRL can be observed for solutions in passenger vehicles and city buses. The same happens for the results by the CRI level.

According to intuition, the lowest level of currently estimated readiness and trading is about the use of hydrogen in the field of commercial aviation and large marine vessels.
The aforementioned observations also refer to the perspective of implementing individual technologies
