Low-Head Hydropower for Energy Recovery in Wastewater Systems

Optimal Sizing of Low Head Hydropower Plant- A Case Study of Hydropower Project at Head of UCC (Lower) at Bambanwala

Pakistan is facing serious shortfall of electricity for few decades. Small hydropower projects can alleviate the worsening situation. The sizing of a low head hydropower plant plays a vital role in establishing the feasibility of the project. The plant needs to be optimized for energy produced, efficiencies of the plant components, number of units and its financial/economic parameters. This pap...

Modeling California’s high-elevation hydropower systems in energy units

[1] This paper presents a novel approach for modeling high-elevation hydropower systems. Conservation of energy and energy flows (rather than water volume or mass flows) is used as the basis for modeling more than 135 high-elevation high-head hydropower sites throughout California. The unusual energy basis for reservoir modeling allows for development of hydropower operations models for a large...

Energy Recovery Design for Low-Power ASICs

Three decades ago, theoretical physicists suggested that the controlled recovery of charges could result in electronic circuitry whose power dissipation approaches thermodynamic limits, growing at a significantly slower pace than the fCV 2 rate for CMOS switching power. Early engineering research in this field, which became generally known as adiabatic computing, focused on the asymptotic energ...

Improvement of Overall Efficiency in the Gas Transmission Networks: Employing Energy Recovery Systems

This study mainly focuses on enhancing the overall efficiency of gas transmission networks. The authors developed a model with detailed characteristics of compressor and pressure reduction stations. Following this, they suggested three different systems with gas turbine including: organic rankine cycle (ORC), air bottoming cycle (ABC), and ABC along with steam injection (SI-ABC). In addition, u...
