“…The variation of the thermal losses that occur in the low and medium temperature networks throughout the year are represented in Figure 7. The evaluation of the investment associated to the different subsystems has been done according to [16,17], based on new construction systems. DH incomes will be the result of the energy sold by the sale price.…”

“…The sustainability of biomass district heating rural networks will depend on the local biomass availability. The price of biomass depends on the proximity between the energy resource and the location of use [10,16,17]. The compensations that could arise in the local economy must be identified to ensure a stable and balanced development of heating networks in rural areas, the sector and the entire value chain [18].…”

Biomass heating networks provide renewable heat using low carbon energy sources. They can be powerful tools for economy decarbonization. Heating networks can increase heating efficiency in districts and small size municipalities, using more efficient thermal generation technologies, with higher efficiencies and with more efficient emissions abatement technologies. This paper analyzes the application of a biomass fourth generation district heating, 4GDH (4th Generation Biomass District Heating), in a rural municipality. The heating network is designed to supply 77 residential buildings and eight public buildings, to replace the current individual diesel boilers and electrical heating systems. The development of the new fourth district heating generation implies the challenge of combining using low or very low temperatures in the distribution network pipes and delivery temperatures in existing facilities buildings. In this work biomass district heating designs based on third and fourth generation district heating network criteria are evaluated in terms of design conditions, operating ranges, effect of variable temperature operation, energy efficiency and investment and operating costs. The Internal Rate of Return of the different options ranges from 6.55% for a design based on the third generation network to 7.46% for a design based on the fourth generation network, with a 25 years investment horizon. The results and analyses of this work show the interest and challenges for the next low temperature DH generation for the rural area under analysis.

“…Recent research relating to district heating have mostly focused on alternative energy sources and technologies, such as waste heat [33,34], solar heat [35], biomass [36][37][38], heat pumps [39][40][41] and natural gas [42]. In order to handle the low energy efficiency and pollutant issues of coal-fired district heating, a low temperature air source heat pump was proposed as offering a more effective heating system to coal-fired district heating, to be used in Beijing [43].…”

Although district heating is an energy-effective solution for cold countries, the coal-fired district heating sector is still facing significant challenges as regards sustainable development, during its operational stage. In order to achieve better operational performance, public private partnerships (PPP) have been introduced in relation to managing clean coal district heating, as a value for money (VfM) solution. To date, however, studies of the application of clean coal in district heating operations are rare and the lack of an evaluation framework hinders the effectiveness test on this sustainable solution. This research aims to investigate the effectiveness of PPP as a VfM solution to the operation of clean coal district heating, by developing an assessment framework on the basis of three dimensions of sustainability: economic, social and environmental, and discussing the proposal, by means of a case study. The assessment results show that the PPP operation offers good VfM performance but with room for improvement, including more user engagement. This research contributes to the literature on clean coal district heating and PPP by providing a comprehensive assessment framework for evaluating VfM performance of the concept. The application of the framework can help the authorities with a robust PPP assessment and thus, improve the sustainable performance of the clean coal heating operation.

“…Biomass exists in a variety of different materials: wood, sawdust, straw, seed waste, manure, paper waste, household waste, wastewater, etc. [25]. The characteristics of some materials allow them to be used as fuels directly; however, others require a series of pretreatments, which require different technologies before they can be used.…”

Biomass as Renewable Energy: Worldwide Research Trends

The world’s population continues to grow at a high rate, such that today’s population is twice that of 1960, and is projected to increase further to 9 billion by 2050. This situation has brought about a situation in which the percentage of the global energy used in cities is increasing considerably. Biomass is a resource that is present in a variety of different materials: wood, sawdust, straw, seed waste, manure, paper waste, household waste, wastewater, etc. Biomass resources have traditionally been used, and their use is becoming increasingly important due to their economic potential, as there are significant annual volumes of agricultural production, whose by-products can be used as a source of energy and are even being promoted as so-called energy crops, specifically for this purpose. The main objective of this work was to analyze the state of research and trends in biomass for renewable energy from 1978 to 2018 to help the research community understand the current situation and future trends, as well as the situation of countries in the international context, all of which provides basic information to facilitate decision-making by those responsible for scientific policy. The main countries that are investigating the subject of biomass as a renewable energy, as measured by scientific production, are the United States, followed by China, India, Germany and Italy. The most productive institutions in this field are the Chinese Academy of Sciences, followed by the National Renewable Energy Laboratory, Danmarks Tekniske Universitet and the Ministry of Education in China. This study also identifies communities based on the keywords of the publications obtained from a bibliographic search. Six communities or clusters were found. The two most important are focused on obtaining liquid fuels from biomass. Finally, based on the collaboration between countries and biomass research, eight clusters were observed. All this is centered on three countries belonging to different clusters: USA, India and the UK.
