Trees and power lines

by Leave a Comment

Trees are an important part of our lives; they add aesthetic value to the surrounding environment, improve air and water quality, reduce soil erosion, and provide shade during the scorching summer months.

Likewise, power lines serve the machinery and equipment we interact with every day, adding luxury and efficacy to our lives.

While these two provide amazing benefits, when trees and power lines are in close proximity to roads, they become a potential hazard to motorists and can cause extreme vehicle damages and bodily injuries if they fall over or motorists accidentally run into them.

Read on to find out how to stay safe while driving on roads with trees and power lines. [Read more…] about Trees and power lines

Hanwha Energy celebrates completion of ‘world’s first and largest’ hydrogen fuel cell power plant

by Leave a Comment

Hanwha Energy hosted an event at its Daesan Industrial Complex in Seosan, Korea to celebrated the completion of a hydrogen-fuel-cell power plant that only uses recycled hydrogen.

At the event, Hanwha Energy CEO In-Sub Jung was joined by South Korea’s Prime Minister Sye-kyun Chung, Vice Minister of Trade, Industry and Energy Seung-il Chung, Chungcheongnam-do Governor Seung-jo Yang, Member of the National Assembly Myung-sun Kim, and Seosan Mayor Jeong-ho Maeng.

Built by Hanwha Engineering & Construction, the new byproduct-hydrogen-fuel-cell power plant cost $212 million. It occupies 20,000 sq m of the Daesan Industrial Complex. [Read more…] about Hanwha Energy celebrates completion of ‘world’s first and largest’ hydrogen fuel cell power plant

Michigan university scientists’ new solar panels could eventually lead to self-powering skyscrapers

by Leave a Comment

Imagine if all the glass we see on the sides of skyscrapers and other buildings were actually solar cells in disguise, collecting energy from the sun and helping to power the building and reducing our reliance on fossil fuels. 

That is the dream of many scientists who are working on the technology. Essentially, they want to replace the silicon material that glass is made out of with material that is more suitable for capturing solar energy.

While green energy has made great strides in recent years – with Germans as a nation recently using more electricity from alternative sources than traditional gas- and oil-based power – there’s still a long way to go.

Difference Between Three-Phase and Single-Phase Power

by Leave a Comment

In today’s advanced and technological upbringings, the power of electricity has become more than a human necessity. People use electricity for heating, cooling, refrigerating, using a computer, and many more.

Similar to your mobile and home appliances, you cannot function and be productive without plugging in your devices or charging your mobile phones in a day. Hence, electricity has recalibrated our lives since the day of its discovery.

Today, the United States accounts for one of the economic leaders in the $6 trillion global energy market. [Read more…] about Difference Between Three-Phase and Single-Phase Power

Amsterdam launches ‘largest smart electric vehicle charging network’

by

A consortium of public-private companies and organisations in Amsterdam has launched what it claims is the “largest smart electric vehicle charging network” in the city.

Vattenfall and the City of Amsterdam, together with grid owner Liander, the infrastructure competence center Elaad, and the Amsterdam University of Applied Sciences, launched what they call “Flexpower”.

They say it is the largest public smart charging network for electric vehicles in Amsterdam, and add that the innovative solution enables faster charging, maximal use of renewable electricity and more efficient use of the electric grid in Amsterdam.

Toyota introduces station for the production and supply of hydrogen from renewable energy

by

Toyota Motor Corporation (Toyota) has newly introduced ‘SimpleFuel’ to its Motomachi Plant in Toyota City, Aichi Prefecture, Japan.

SimpleFuel is a small water electrolysis-based machine for hydrogen generation and filling that can produce, store, and supply hydrogen by making use of electricity generated from solar power.

It uses electricity from solar panels at the plant site to produce low-carbon hydrogen from the electrolysis of water, which is then supplied to fuel-cell (FC) forklifts after it is compressed and pressurised.

Power grid: Integrating large-scale battery energy into the electricity network

by

One of the most challenging issues for power grids is energy storage. The ability to store energy would enable the supply of uninterrupted electricity to customers, but battery technology has been too expensive or not good enough – until now, with all the electric cars on the roads. Claude Olsen, of Gemini.no, explains

Batteries have become so cheap that they can be used for more than just smartphones and electric cars. Now, national electricity network companies will use them to stabilize the power grid.

In the Norwegian city of Skien, the Odds football stadium Skagerak Arena will, next year, be almost self-sufficient with electricity from 5,000 square meters of solar cells on the roof.

However, since the big peak in power consumption is on the day of the match, the energy produced on the other weekdays must be stored in large batteries.  [Read more…] about Power grid: Integrating large-scale battery energy into the electricity network

Electric power: Clean energy infrastructure driving switch from AC to DC

Nikola Tesla was a famous scientist who developed alternating current, the means of distribution for electricity for the vast majority of devices, appliances and machines in households and factories and just about every other electrified thing in the world today. 

But even as Tesla was inventing much of the technology used in the alternating current electricity supply system, another famous inventor, Thomas Edison argued that direct current was the best way to distribute electricity.

By the time Tesla tech came onstream, DC had already been in use for a decade, but within a relatively small area, and Edison lost that argument mostly because the components of an alternating current grid enabled electricity to be carried far and wide beyond the power generating facility.  [Read more…] about Electric power: Clean energy infrastructure driving switch from AC to DC

Siemens offers its employees free charging for their electric vehicles

Free “refuelling” at up to 100 Siemens locations in Germany, with charging stations “internationally linked”

Beginning in 2017, Siemens employees at as many as 100 of the company’s locations in Germany can “fill up” their electric vehicles free of charge. This will apply not only to all-electric vehicles but also to plug-in hybrid electric vehicles.

For this service, Siemens will use its existing network of charging stations, which it is expanding with normal and high-speed charging stations.

To reduce their carbon footprint, the charging points will supply electricity only from renewable energy sources. The electricity and the use of the charging stations are likely to be free for the duration of 2017.  [Read more…] about Siemens offers its employees free charging for their electric vehicles
