The fuel and energy crisis and the increasing pollution of the environment are one of the pressing problems facing humanity today. In this regard, the question of finding new alternative energy sources is urgent. Today there is an increasing interest in solid biofuels and new methods for improving the properties of biofuels are being developed and improved, such as grinding, drying, pressing, and more recently, heat treatment. Thermal methods of impact on biomass require special attention of researchers, because while their consumption consumes some energy, it leads to an increase in the cost of production. But at the same time, they allow not only to increase the specific energy characteristics of biofuels by removing moisture and ballast components, but also to obtain fuel with new useful features (such as hydrophobicity, low greenhouse gas emissions, diminishing smoke and odours, no corrosive substances). Depending on the biomass heat treatment modes, a different end product can be obtained, and changes in it can be estimated by the weight loss. Investigations of this process were carried out in the educational scientific laboratory "DAK GPS" of the State Agrarian and Engineering University in Podilya at the plant for the torrefaction of tape-type biomass with passive interaction with the material. Control automatics allow to adjust and maintain the temperature in the thermal chamber, as well as the speed of movement of the tape, which determines the residence time of the biomass under the influence of thermal action. During each 10-minute heat treatment cycle in 20 ℃ increments, mass loss was determined, and additional factors were recorded that could indicate the beginning of internal changes in the material being studied (smoke, odour, etc.). As a result, the conducted research proved that the torrefaction process of different raw materials meets its own temperature range, in which there are active changes of material, namely converts raw biomass into torrefied product. This range for the studied samples is 40-50 ºC, in particular for barley and soybeans the process of torrefaction begins at 185-195 ºC and ends at 230-240 ºC, for poplar, willow and miscanthus these figures are respectively 235-245 ºC and 280-300 ºC. As shown by the studies, for most biomaterials of plant origin we can distinguish the beginning of intensive transformation and its end, after which there is a sharp slowdown in the weight loss, and accordingly, in the energy density of the samples.

“…Based on the research, it is established that the forecasted increase in the biohydrogen production projects, and the related technologies, will reduce the total biohydrogen production costs. Starting in 2030, 80% of biohydrogen production from agricultural raw materials (Tryhuba et al, 2021b). Now in Ukraine it is economically profitable to use "green" hydrogen.…”

Over the last few years, hydrogen energy has shifted from a little-studied field to the main one with which leading western countries associate the prospects of their national economies. The reasons are the unprecedented pace of development of hydrogen technologies. It turned out that they are able to provide significant reductions in greenhouse gas emissions, and thus bring closer the solution to the problem of global climate change. The first and foremost purpose of our investigation is to reveal that our country has ample opportunities to become the main supplier of hydrogen to the EU market, overtaking North Africa in the competition. Using the methods, authors studied the targets of the European funds towards development of energy production from biohydrogen, studied the potential for the implementation of hydrogen projects, possibilities of financing them and a potential ability of Ukraine to form internal and external markets for hydrogen energy. One of the main issues of Ukraine's possible participation in Europe's hydrogen energy program as a supplier and producer of renewable hydrogen is the possibility of its technically safe and cost-effective transportation to EU countries. As a conclusion to the authors’ research, the path of the hydrogen industry development in Ukraine will help to receive additional investments in the Ukrainian economy for creation of new capacities for "green" hydrogen production. In return, Europe will receive research and evolution of the bioenergy component of the economy, which will permit the safe transition of Europeans to an affordable, competitive, and stable energy system.

“…Waste generated in one production sector can be input material in the production of other goods. Waste materials can be used both directly as raw materials and through the use of the elements contained in them as a source of plant nutrients [ 4 , 5 , 6 , 7 ]. The re-use of plant nutrients contained in rainfall allows the biogeochemical cycle of elements to be limited to a single farm or economic region.…”

The utilization of municipal waste and sewage sludge as a source of energy is technically very difficult due to high variability of their physical and chemical properties. The aim of this study was to evaluate the efficiency of the conversion of biomass contained in the whitewater fraction of municipal waste and sewage sludge by means of methanogenesis. The second objective was to assess the chemical composition of the digestate in the context of its use for fertilizer purposes. The whitewater fraction of municipal waste and sewage sludge was subjected to methanogenesis under static experimental conditions, according to DIM DIN 38414 methodology. The methanogenesis of concentrated substrates used in agricultural biogas plants was taken as a reference to evaluate the efficiency of the process. The organic fraction of the municipal waste was characterized by approximately 30% lower value of the soluble COD, with a comparable level of total COD compared to other materials. The total biogas yield, i.e., 404 dm3 per 1 kg of dry weight of the batch, was measured in the facility with sewage sludge. In COD value, this is 0.232 dm3·g O2 COD. In the case of corn, these values were, respectively, 324 dm3 and 0.193, and for the organic sub-sieve fraction of municipal waste, 287 dm3·kg−1 dw or 0.178 dm3·g O2 COD, respectively. The type of fermented material did not affect the intensity of biogas production. The maximum level of biogas production occurred between the 13th and 15th day of the process. The digestate obtained in the process of methanogenesis of corn silage and the organic fraction of municipal waste was characterized by good parameters in terms of possible use for fertilization purposes.
