The Inside Story Of The World's Biggest 'Battery' And The Future Of Renewable Energy | CleanTechnica

The Inside Story Of The World's Biggest 'Battery' And The Future Of Renewable Energy | CleanTechnica | Hydropower | Scoop.it

The largest battery in the world has sat quietly in George Washington National Forest along the Virginia-West Virginia border for nearly 30 years. A five-hour drive from the nation’s capital, it sits in the middle of the Appalachians, tucked behind the Blue Ridge Mountains.

 

Very few people in the urban areas that benefit from its power know of its existence, let alone its purpose. Talk to people that live and work a few miles away in Warm Springs, Virginia, and some will have a vague awareness but will readily admit that they don’t spare a thought for how electricity gets to their outlets. Dan Gessler, who works for Dominion Power, the company that operates the facility, put it simply: “I think the vast majority of the public doesn’t even know it exists, it’s up here in the middle of nowhere out in the mountains.”

 

The Bath County Hydro Pumped Storage Facility is not really a battery in the common sense of the term, but it is the largest pumped storage facility in the world. It stores a lot of energy, which helps 60 million people in 13 states (and DC) served by the regional transmission organization, PJM Interconnection. Quite often when someone in that huge area comes home from work and turns on the lights or switches on the TV, some of those electrons flowing down the power lines are coming from two lakes on a mountain in rural Virginia.

 

When Sean Fridley, the facility’s Station Manager, looks at the Upper Reservoir perched a thousand feet above his office, he doesn’t see drops of water. He sees a thousands-of-megawatts-deep block of power, a huge amount of stored potential energy — with more output than the Hoover Dam — that he can turn on with a flick of a switch.

 

“It’s one of the biggest engineering projects, ever,” Fridley said. “The machinery is huge.”

 

But can such a massive “battery” be drained by climate-fueled drought?

European Investment Bank invests £230 million in Central American renewables

European Investment Bank invests £230 million in Central American renewables | Hydropower | Scoop.it

The joint programme with the Central American Bank for Economic Integration will enable more than $500 million of investment in projects in six central American countries: Honduras, Nicaragua, El Salvador, Guatemala, Costa Rica and Panama.

 

EIB vice president Magdalena Álvarez Arza said: "Considerable investment is needed to harness the potential of renewable energy and more efficient energy use to reduce carbon emissions and provide energy essential for economic growth.

 

"The EIB is committed to supporting long-term investment in sustainable energy around the world and enabling low-carbon energy investment in Central America."

 

The new programme follows a similar initiative launched in 2011 between the two investment banks which is supporting hydropower investment in Costa Rica.

 

Of the countries set to receive the cash, Honduras, Nicaragua and Costa Rica currently have installed wind capacity, with Costa Rica leading the way, with 152MW in place.

Michael Mazo's curator insight, December 13, 2014 8:38 PM

It always good to read about regions of the world that adopt green energy, better yet help push others to do so. Central America isn't as highly developed as other parts of the globe, although it has had several project in which alternate energy has been created through various ways. To see a super power like Europe invest money in creating sustainable energy in Central America is a choice made in the right direction. In addition it also paints a good image for others across the world to see and hopefully go green as well. When it comes to reducing emissions and cleaning up the environment, something can always be done

Tajik President Emomali Rahmon sees country's future in hydropower | UPI.com

Tajik President Emomali Rahmon sees country's future in hydropower | UPI.com | Hydropower | Scoop.it

Resource poor, water-rich Tajikistan sees hydropower as a future asset.

Tajik President Emomali Rahmon Wednesday inaugurated a $33.2 million, 220 kilowatt substation upgrade at the Nurek hydroelectric station on the Vakhsh River.

 

The Nurek hydroelectric cascade currently provides energy to about 80 percent of the country's consumers, as well as provides irrigation water to downstream neighbors Uzbekistan, Kazakhstan and Turkmenistan.

 

Tajikistan's hydroelectric ambitions have unsettled Tajikistan's downstream neighbors. Alone amongst the post-Soviet Central Asian states, Tajikistan endured a brutal civil war that began in 1992.

When the conflict ended five years later, the nation's economy was in ruins, with nearly 50,000 dead and what little was left of the Soviet infrastructure largely in shambles.

 

Since the end of the conflict the Tajik government has attempted to improve its economy by assiduously seeking foreign investment, but its marginal industrial base combined with rampant corruption has left the nation largely devoid of foreign direct investment, which in the last two decades has barely topped $1 billion. In contrast, Kazakhstan has received more than $140 billion and neighboring Uzbekistan $50 billion.

 

Dushanbe is accordingly pinning its hopes on hydroelectric power for both indigenous use and exports, generated by the country's alpine lakes and rivers, seeing a situation when its hydroelectric facilities could not only meet domestic demand but would also allow the nation to export electricity to neighboring energy-poor Afghanistan and Pakistan.

Can Tidal Energy Take Off? | The Energy Collective

Can Tidal Energy Take Off? | The Energy Collective | Hydropower | Scoop.it

The small French island of Mont Saint-Michel, a UNESCO World Heritage site, is famous for its fast and forcefully rising tides. The famous writer Victor Hugo once claimed them to be as fast as galloping horses. Tidal energy is all about capturing this energy of the sea. While large tidal projects have been proposed for centuries, actual progress has been slow.

 

The back and forth of the sea is caused by the attraction of celestial bodies, notably the sun and the moon. The understanding of these gravitational forces enables us to make quite accurate tide predictions today. Nevertheless, water levels are still influenced by factors such as the coastline’s shape, weather conditions or local currents. It is this very feature that distinguishes tidal energy from other renewable energy sources, such as wind, wave and solar energy. They are not only hard to predict, but also incredibly variable.

 

Although we can find tides on coastlines around the world, not all locations are suitable for tidal energy generation. Sites need to have substantial volumes of tidal water flow, typically found either in a narrow channel or a bay inlet, to qualify. Depth is another site selection criteria, since insufficient water depth can perturb the water flow and thus the productivity of the tidal project. An adequate sea bottom is essential to the design of tidal energy projects: For a tidal dam, for example, flat profiles are needed. Ideally, a site will be easy to access for maintenance and situated close to a location where repair can be performed as required. Like with any other offshore energy, the closer the site is located to a power distribution network, the better. Some people claim that it is this list of requirements that limits the amount of adequate sites and restrains the growth of tidal energy.

Wave, Tidal, Hydro Can Provide 15% of US Electricity by 2030

Wave, Tidal, Hydro Can Provide 15% of US Electricity by 2030 | Hydropower | Scoop.it

Two reports released today by the US Dept. of Energy (DOE) show that the nation’s conventional hydro, wave, tidal and other water power resources hold the potential to provide 15% of all the electricity the US needs by 2030. The DOE’s new wave and tidal resource assessment reports represent “the most rigorous analysis undertaken to date to accurately define the magnitude and location of America’s ocean energy resources,” according to a DOE press release.

 

US demand for electricity amounts to about 4,000 terawatt (TWh), or 4 quadrillion Watt-hours, of energy per year. Overall, renewable US hydropower resources account for 6%. The average lightning strike’s peak power is said to be about 1 TW. However, according to the DOE’s analysis, maximum theoretical generation from waves and tidal currents is 1,420 TWh, about 1/3 that total.

 

While the DOE acknowledges that not all these resources may be economically or technologically feasible to develop, the results demonstrate the vast potential that does exist, potential that if realized would spur investment, manufacturing, and commercial activity on a nationwide scale, not to mention the green job creation that would occur.

 

The two reports, entitled “‘Mapping and Assessment of the United States Ocean Wave Energy Resource‘ and ‘Assessment of Energy Production Potential from Tidal Streams in the United States,’ calculate the maximum kinetic energy available from waves and tides off U.S. coasts that could be used for future energy production. This represents “largely untapped opportunities for renewable energy development in the United States,” the DOE explains.

tidal energy will be very useful but i dont believe that the world we invest in it that long
Sam Ferris's comment, April 8, 2013 11:29 PM
The fact that this source of energy will be this useful is really good, but water is already an issue on our planet, and even if it is useful enough for that long will people really decide to use it? How much does it REALLY cost? Would the people who need it be able to afford it? The recourse itself is great and so is the outcome, but is the process going to have a positive or negative effect?
