Abstract:
A pump as turbine (PAT) can be a cost-effective and versatile solution to recover energy in several fields of application. However, its optimal exploitation requires a reliable and general methodology for selecting the optimal turbomachine. To this purpose, this paper presents and validates a comprehensive methodology that identifies the best turbomachine (i.e., the one that maximizes the recovered energy) by considering two hydraulic sites and forty-five PATs. In both sites, the methodology correctly identifies the best PAT, which allows for the recovery of up to 45% of the available hydrauli

Abstract:
Water distribution networks (WDNs) are considered a potential renewable energy source, as they have more than enough pressure energy to deliver water to users. To control excessive pressure, WDNs are commonly divided into district metered areas (DMAs) with pressure-reducing valves (PRVs). The energy wasted by PRVs can be recovered using pumps as turbines (PATs). However, selecting the appropriate pump remains a challenge, as it must account for daily pressure and flow variations from consumers (off-design conditions). In this article, a combination of models was validated and applied to select

The use of Pumps-as-Turbines (PaTs) to replace hydraulic turbines as energy-recovery units in industrial and civil applications is widening the penetration of hydropower in small-scale plants.

Power generation is becoming an increasing problem in South Africa. South Africa produces approximately 90% of its electricity from coal-fired power stations and only 5% from hydroelectric power stations and pumped storage. Durban has a very steep topography, which results in high pressure in certain parts of the water distribution network (WDN). Leakage is costly and contributes to a large extent to non-revenue water (NRW) in the network. Pressure reducing valves (PRVs) are used in WDNs to control the pressure in the pipework to reduce leakage. This excess pressure can be used to generate ele

Sustainable development has been an idea raised in recent years. The results are related to the improvement and the use of new technologies to maximize efficiency in water management. However, energy consumption has been increasing as a consequence of new management and uses of water. Especially in pressurized water distribution systems, the use of pressure reduction valves (PRVs) increases the water usage efficiency but it decreases the energy consumption efficiency, since the valves dissipate energy that could be recovered.

The vast majority of energy-generating systems are heat engines, which depend on the combustion of the fuel, and the recovery of the heat of combustion. The fossil fuels are coal, oil, and natural gas; and they may be directly combusted, or converted prior to combustion. The conversion of coal may be to a liquid fuel, or, more commonly, to a gaseous fuel; the crude oil may be converted to a lower molecular weight liquid, or again to a gaseous fuel. The natural gas may be converted, in some cases, to a liquid fuel.

Abstract:
Abstract A key consideration in the design of walking machines is the minimization of energy consumption. Two main avenues of research have been pursued in the past (a) finding an optimal gait which reduces energy consumption or (b) the employment of energy storage devices to recover energy from one step to the next. This study follows the latter approach, which has hitherto concentrated on hopping machines. Several practical design considerations for energy recovery in multi-legged walking machines, where a stance phase prevents the immediate recovery of energy from one step to the next, are

Abstract:
Integrated coal gasification combined cycle systems offer a very efficient and environmentally superior method for converting coal or petroleum coke to electric power. The high efficiency is derived from effective utilization of high level energy in all parts of the IGCC system. Entrained flow gasification represents one of the cleanest and most efficient technologies for converting coal or coke to syngas, and also produces significant quantities of high level sensible heat in the raw syngas exiting the gasifier. This heat can be recovered as high pressure steam through the use of syngas coole

Abstract:
Summary In recent years, the Flemish Pass Basin has been gaining momentum as an area of potential high-volume resources on the frontier of remote, deep-water offshore oil development. This simulation study utilizes three sector models representing regional, discovered reservoirs, and two tuned fluid models representing oil sampled from wells in the Flemish Pass Basin. Generally speaking, WAG is considered a late-life enhanced oil recovery (EOR) technique, while implementing WAG immediately upon first oil for secondary recovery is less common; however, may be equally or more valuable.

Abstract Objectives/Scope As one of the largest emitters in the world, the oil and gas industry needs more efforts on greenhouse gas reduction. Methane, as a potent greenhouse gas, could largely determine whether natural gas could serve as a bridging energy towards a sustainable future.

Abstract:
Two important and current topics of interest for gas machinery operators are emissions and energy efficiency. Current climate change legislation is leaning towards reduced emissions and improvements in energy utilization efficiency, which has renewed the interest in Waste Heat Recovery (WHR) at pipeline stations. In the past, the focus of WHR has been on large-scale applications, with little attention paid to small-scale WHR systems. Many of the concepts discussed in this report have been used in other applications or part of the concept has been implemented before, but not while using waste h

Abstract:
Italian BIPV experienced a strong innovation period with the past FiT Law (around 2.5 GW of BIPV capacity installed), followed by a decrease and then a recovery from 2017. TIS analysis shows a niche BIPV market today with significant potential from the past FiT Law and for the new challenges of the Italian National Energy and Climate Plan, with some difficulties to overcome such as costs, performance, lack of BIPV associations, and permitting in historical cities.

1.1 Macroeconomic summary Economic recovery has consistently outperformed the technical staff’s expectations following a steep decline in activity in the second quarter of 2020. At the same time, total and core inflation rates have fallen and remain at low levels, suggesting that a significant element of the reactivation of Colombia’s economy has been related to recovery in potential GDP. This would support the technical staff’s diagnosis of weak aggregate demand and ample excess capacity. The most recently available data on 2020 growth suggests a contraction in economic activity of 6.8%, lowe

Bridge closures can result in severe costs, not only in the form of repair or replacement, but also in the form of economic losses related to medium- and long-term interruption of businesses and disruption to surrounding communities. In addition, continuous functionality of bridges is very important after any seismic event for emergency response and recovery purposes.

Abstract:
While inflation fell significantly in 2024, it continues above the 3% target. However, monetary policy measures and corrections in particular factors that exert upward price pressures have helped direct inflation toward the objective. Economic activity continues to recover and is expected to continue growing. The monetary policy interest rate is compatible with the convergence of inflation to its 3% target and the gradual recovery of economic growth toward more sustainable levels. Inflation has fallen significantly, from 9.3% in 2023 to 5.2% in 2024. During this year and into the next, inflati

Inflation in major consumer price index (CPI) baskets has accelerated year-to-date, rising in March at an annual rate above 3%. Food prices (25.4%) continued to contribute most to rising inflation, mainly affected by a deterioration in external supply and rising costs of agricultural inputs.

Inflation continues to decline but remains well above 3%. It is anticipated to decrease significantly in 2024 and draw closer to the established target in the first half of 2025. The ongoing moderation in the economy's price levels is evidenced by the decline in headline inflation from 11% to 9.3% between September and December 2023. A noteworthy contributor to the decrease in inflation has been the reduction of food prices adjustments throughout 2023, complemented by favorable trends in the price of goods.
