Overview

Generating renewable electricity is an important way to reduce carbon dioxide (CO2) emissions and many countries are installing wind and solar power plants to help meet targets for cutting CO2. One drawback of these energy sources is their variability: the wind tends to blow intermittently and solar power is only avail

A national electricity grid must always be able to meet the needs of its users. This requires it to be: stable, maintaining the required electrical frequency (50 Hz in the UK); balanced, continuously matching supply to demand; and adequate, ensuring total generation capacity is never outstripped by demand.

Grid supply is split into three tiers: base, intermed

Overview

Electrochemical processes, such as the industrial production of caustic soda and chlorine, use large quantities of electricity which contribute significantly to production costs, up to 70% in some cases. They also produce hydrogen as a waste product (see diagram), which is either combusted or vented to the atmosphere. Fuel ce

Overview
Events such as Hurricane Katrina in 2005 have focused attention on the availability and reliability of telecommunications services worldwide. Both wireless and wireline communications are expanding globally, so the provision of reliable, economical power is vital. Terrestrial Trunked Radio (TETRA) networks in use by emergency services, military personnel and government agencies require total system reliability during emergencies, when loss of communication would

Waste management is a necessity wherever people live, but traditionally waste is viewed as a problem, something that pollutes and needs reducing or mitigating. What if this mindset could be changed such that we value our waste as a source of bioenergy? Waste contains significant quantities of energy and, if we could harness this close to where the waste is generated and convert it to a useable form, it could provide both a distributed source of electricity and contribute to solving the global

A wide variety of technologies are available to provide heating and electricity to our homes. In countries with a stable electricity grid, lighting and heating are taken for granted; but the desire for cleaner energy is highlighting how dirty grid electricity is around the world, and concerns over the future of nuclear power are adding to the debate. Many countries also have a network that distributes natural gas, and off-grid options such as heating oil or LPG are available, but when burned

In an effort to gain maximum engine performance and stay within the local exhaust emission limits over a wide range of engine load and ambient conditions, operators at the County Sanitation Districts of Los Angeles County’s Joint Water Pollution Control Plant wastewater treatment plant near downtown Los Angeles have installed Continental Controls Corp. ECV5 air/fuel ratio control valves on five gas-fueled engines in an effluent pump station.

While California is the most populated state in the nation, it is also home to some of America’s most natural and pristine wilderness and recreation areas. One such venue is the Snow Summit Ski Resort in Big Bear Lake.  Situated just over two hours from Los Angeles, Snow Summit is a fullservice winter resort that opened in 1952 and operates an average of 142 days a year.

NOx Abatement is a Non-Selective Catalytic Reduction (NSCR) technology that has a long and proven track record for controlling NOx emissions from nitric acid manufacturing plants. It can be used to alter the NO to NO2 balance (decolourization) or to eliminate NOx through catalytic reaction with a fuel as a reductant.
