Special Issue Information

Dear Colleagues,

We are glad to share the great success of our Special Issue “Sustainable Combustion Systems and Their Impact”.

We now continue to launch the second volume of this Special Issue: “Sustainable Combustion Systems and Their Impact II”.

As the world moves into the third decade of the 21st century, a change in landscape is expected regarding global energy demand and consumption. The transportation sector is one of the biggest consumers of energy, resulting in significant environmental effects. For example, even with the most optimistic projections for electric vehicles, the majority of vehicles sold in 2040 will still feature internal combustion engines. Thus, we must continue to consider all opportunities to minimize IC engine emissions and pathways to reduce the CO2 footprint of future vehicles. On the other hand, hydrogen, which can be used in internal combustion engines and fuel cells, is seen as one of the leading energy vectors of the future. However, this technology still faces several challenges in terms of both production/storage and usage. Thus, even though electrification offers substantial advantages for many transport applications in reducing CO2 and localized polluting emissions, it falls a long way short of fulfilling all of society's requirements for social and business mobility. This Special Issue aims to present original research articles as well as critical review articles that cover relevant, current topics related to laboratory research and in-vehicle test data of various sustainable combustion strategies, which aim to minimize the environmental burden. This Special Issue of the Energy and Environment section of Energies is dedicated to sharing ideas regarding energy and the environment, advancing the knowledge among practitioners, scientists, researchers, policymakers, and professionals toward nurturing innovative concepts required to solve problems and ensure sustainable development.

Thermoelectric generators are devices that harvest waste heat and convert it into useful power. They are considered as an additional power source in the domestic sector, but they can also be installed in off-grid objects. In addition, they are a promising solution for regions where there is a lack of electricity. Since biomass heating and cooking stoves are widely used, it is very appropriate to integrate thermoelectric generators with wood-fired stoves. This paper shows the experimental analysis of a micro-cogeneration system equipped with a wood-fired stove and two prototypical constructions of thermoelectric generators dedicated to mounting on the flue gas channel. The first version was equipped with one basic thermoelectric module and used to test various cooling methods, while the second construction integrated four basic thermoelectric modules and a water-cooling system. During the tests conducted, the electricity generated in the thermoelectric generators was measured by the electronic load, which allowed the simulation of various operating conditions. The results obtained confirm the possibility of using thermoelectric generators to generate power from waste heat resulting from the wood-fired stove. The maximum power obtained during the discussed combustion process was 15.4 W (if this value occurred during the entire main phase, the energy generated would be at a level of approximately 30 Wh), while the heat transferred to the water was ca. 750 Wh. Furthermore, two specially introduced factors (CPC and CPTC) allowed the comparison of developed generators, and the conclusion was drawn that both developed constructions were characterized by higher CPC values compared to available units in the market. By introducing thermoelectric modules characterized by higher performance, a higher amount of electricity generated may be provided, and sufficient levels of current and voltage may be achieved.
