“…Since the capture equipment requires energy (both steam and electricity), the net output of the site is reduced if the coal plant itself is used to power the capture equipment. The impact on net output is a reduction on the order of 17-25% of annual electricity generation [52][53][54]. Another option is to add a new combined cycle natural gas plant to an existing coal power plant specifically to run the capture equipment.…”

Out of 2 TWe of coal power plant capacity in operation globally today, more than half is less than 14 years old. Climate policy related to limiting CO2-emissions makes the longer-term operation of these plants untenable. In this study, we assess the spectrum of available options for the future of both equipment and jobs in the coal power sector by assessing the full scope of “retrofit decarbonization” options. Retrofit decarbonization is an umbrella term that includes adding carbon capture, fuel conversion, and the replacement of coal boilers with new low-carbon energy sources, in each case re-using as much of the existing equipment as economically practicable while reducing or eliminating emissions. This article explores this idea using the Polish coal power fleet as a case study. Retrofit decarbonization in Poland was shown to be most attractive using high-temperature small modular nuclear reactors (SMRs) to replace coal boilers, which can lower upfront capital costs by ~28–35% and levelized cost of electricity by 9–28% compared to a greenfield installation. If retrofit decarbonization is implemented globally by the late 2020s, up to 200 billion tons of otherwise-committed CO2-emissions could be avoided.

“…As with any different technology, the risks here are strictly specific. A number of authors Zaina et al 2011;Nyenno et al 2020;Bartela et al 2015) have made a risk assessment of various facilities, but there are none regarding the implementation of a biogas utilization plant from a livestock farm.…”

The introduction of increasingly strict rules related to the processing and storage of animal waste, the growing demand for energy and the creation of sustainable animal husbandry have led to an increased interest in the production of clean energy from animal waste. The production of biogas and its subsequent burning on the farm is among the most promising technologies. One of the possibilities for the utilization of biogas is through the use of small aggregates for the combined production of electricity and heat energy based on an internal combustion engine. Analysis of such facilities that have been put into operation show that alternative technologies using biogas as fuel are better than conventional options, both from an economic and an environmental point of view. In this sense, however, the introduction of such a technology into operation is always associated with a number of risks, since investments in new technologies are influenced by technical and economic uncertainty. When planning and preparing the plan for the construction of such a biogas facility, the investment costs, technical support and profitability of the project are essential. Introducing critical economic and technical parameters to inform the farmer of all possible investments, operational and unforeseen risks will allow him to accept the challenges and choose the best solution for his farm. In this publication, an analysis and assessment of the risk has been carried out based on the characteristics of the technology -the possible consequences of the risk are also presented. 124A risk matrix related to the specifics of the object and the technology is proposed, with the help of which, the type of risk is identified. Based on an analysis of the obtained results, a motivated proposal for reducing the risk is made.

Following the entry into force of the Regulation (EU) No 517/2014 of the European Parliament and of the Council of 16 April 2014 on fluorinated greenhouse gases and repealing Regulation (EC) No 842/2006, the scope of refrigerants, which have so far been commonly used is very limited. All preferred refrigerants are mostly flammable and explosive, and they include R32, R1234yf, R1234ze, R290 (propane), R600a (isobutane), R717 (ammonia). However, it should be noted that refrigerants such as R32, R1234yf, R1234ze are classified as mildly flammable and has been created for them, in accordance with ISO 817 standard, special group called A2L. It is also worth noting that the new classification moved ammonia to the group B2L - that means is toxic and mildly flammable. The article focuses on defining the conditions in which there is possible to build safely split installation in which the propane is a refrigerant. It turns out that small splits are devices which can be used safely with R290 in most cases.
