Nuclear power and water consumption
The UK Government is accelerating plans for homegrown power, and nuclear energy is a significant part of its strategy. The target is eight reactors by 2030, with a target of one nuclear reactor per year instead of one per decade. The government wants 24GW of nuclear energy by 2050, satisfying up to 25% of national energy demand. Nuclear power is safe and is the most reliable energy ...

Ellen Williams: The future of energy innovation
As director of the U.S. Advanced Research Projects Agency–Energy, Ellen Williams plays a pivotal role in cultivating and guiding energy technology discovery and development in the United States. Ensia recently invited Williams to share her views on what we should watch for in the wide world of energy innovation in the months and years to come. What in your mind is the most important ...

Optimizing Water Management in Hydraulic Fracturing for Shale Oil and Gas Production
Centralized treatment of wastewater is emerging as a viable solution for long-term efficiency in managing water sourcing and wastewater treatment in hydraulic fracturing. The number of hydraulic fracturing (fracking) shale oil and gas wells in the United States continues to increase. Within the Bakken Shale formation alone, in North Dakota and Montana, upwards of 15,000 hydraulic fracturing ...

Cold exergy recovery during LNG regasification through a closed Brayton cycle
The liquified natural gas (LNG) regasification process is a source of cold exergy capable of being recovered for the exploitation of energy conversion. This paper presents a novel power plant structure that makes use of the LNG regasification process to increase the energy and exergy efficiency. The power plant consists of a closed Brayton cycle (CBC) fuelled by the flue gas released by the ...

Wind turbines and health
The American Lung Association's agenda for the new administration, Protect the Air We Breathe: An Agenda for Clean Air, states: "Climate, energy and clean air are inexorably linked. Solutions that lead to cleaner air must be included in any approach to cleaner, more efficient energy use and reductions in global warming." 1 Wind energy is one such solution - a clean energy source that can ...

Performance enhancement of GT–ST power plant with inlet air cooling using lithium bromide/water vapour absorption refrigeration system
Performance improvement techniques in power generation systems especially in gas turbine–steam turbine (GT–ST) combined cycle (CC) power plants by compressor inlet air cooling prove to be much improvising. In this work, the performance enhancement of CC power plant by inlet air cooling method using lithium bromide–water (LiBr/H2O) absorption refrigeration system powered by waste heat from heat ...

New definition of fluid exergy in a gravitational field
This paper discusses the concept of working fluid exergy in an atmosphere stratified by a gravitational field, particularly the hot humid air in the atmosphere. A definition of exergy, different from that recently proposed by Petela (2008), is presented. Thermodynamic diagrams illustrate its elements and its technically feasible part in a transparent way. Reference papers are given for ...
