Introduction to Energy Storage

Introduction to Energy Storage

Electricity is rarely stored but instead is usually converted to another energy form, such as electrochemical, potential or thermal. As a result, energy demand and supply need to be carefully balanced. This was more achievable with the traditional grid system using predictable fuel sources such as fossil fuels and nuclear fuel than it is with […]

The Global Hydro Industry

The Global Hydro Industry

Water has been used as a source of energy for millennia. All of the civilisations of antiquity used water extensively, employing water wheels and other devices to raise water to higher levels for irrigation.  Hydroelectric generation originated with the invention of the hydro turbine in France in the 1830s. The transmission of hydroelectric power was […]

Electricity Transmission and Distribution

Electricity Transmission and Distribution

The half century from 1880 to 1930 constituted the formative years of the history of electric power systems. The three components of the total system (generation, transmission and distribution) evolved in three separate stages. The first stage, in the earliest days of the supply industry, was the development of small local generators, initially providing power […]

Smart Grid Security

Smart Grid Security

One of the biggest concerns for smart grid developers is cyber security due to the reliance on IT communication networks. While the current grid is not immune to energy theft, fraud and malicious cyber attacks, the smart grid poses new security issues. It is more likely now that theft, malicious attack and fraud will be […]

Energy Efficiency

Energy Efficiency

Energy efficiency is often referred to as the third fuel type, the other two being fossil fuels and renewable energy. No one definition or measure of energy efficiency is available. However, it is generally agreed that energy efficiency refers to changes that decrease the amount of energy used to produce a unit of a certain […]

The GE Coup

The GE Coup

 It’s no coincidence that the phrase ‘coup d’etat’ is a French one, however, with an American multinational looking to secure a major French industrialist; the outcome is rather surprisingly in favor of l’Americain . The GE, Alstom tie-up is of major impact to GE’s footprint in Europe. In what looks like what will be a […]

Undergrounding, A Continuing Trend in The Transmission & Distribution Sectors

Undergrounding, A Continuing Trend in The Transmission & Distribution Sectors

With increased urbanisation and infrastructure replacement, the benefits of undergrounding are starting to outweigh the costs. NRG Expert takes a look at some of the advantages and disadvantages to this process and answers the question, ‘will it continue?’ Electrical energy worldwide is mainly transmitted with High Voltage Alternating Current (HVAC), overhead line technology. 96% of […]

Electric Vehicle Battery Market Wide Open

Electric Vehicle Battery Market Wide Open

The electric vehicle market is now wide open as Better Place, have declared bankruptcy after failing to pull off their ambitious ‘electric battery swapping station’ concept. Learning from Better Place’s mistakes, Battery Fueling are entering the electric vehicle battery market with their ‘US patent-pending Battery Fueling’ concept. Battery Fueling have designed a new concept for […]

Massive Wyoming Lithium Deposit ould mean Implications for Battery Industry, NRG Expert Analyst Reports

Massive Wyoming Lithium Deposit ould mean Implications for Battery Industry, NRG Expert Analyst Reports

Researchers at the University of Wyoming have uncovered a massive deposit of lithium in the south western region of the state while investigating the possibility of storing CO2. Experts estimate that the area could contain up to 18 million tons, or the equivalent of 720 years of total worldwide production. As lithium-ion batteries increasingly become […]
