Masdar est une ville laboratoire, où sont développées et testées toutes les technologies de pointe qui nous aideront à nous passer de pétrole.

Elle deviendra un modèle pour le monde entier puisque chaque pays doit amorcer dès aujourd’hui sa transition énergétique, en plus elle contribuera de façon significative a préserver les ressources et a augmenter le PIB, il n'y a que les idiots qui resteront dans leurs villes dortoirs pollués et surpeuplés.

Energie… Comment ? Tout d’abord en faisant des cités pensées pour être radicalement beaucoup moins gourmandes en énergie - Par leur structure architecture globale -.

Puis par usage massif de l’énergie solaire avec un appoint du nucléaire.

Saudis Could Export Solar for the Next Twenty Centuries

Posted on April 12, 2012 by Susan Kraemer

Every square meter of Saudi Arabia produces an extraordinary 7 kilowatt hours of energy daily in each 12 hours of sun power. If the Saudis were to use up each days solar energy supply, or 12,425 TWh of electricity, it would be a 72 year supply.

Put another way, in just one day, enough solar energy hits Saudi sands to power the kingdom for 72 years, according to a study made by the World Academy of Science, Engineering and Technology.

That is an extraordinary resource. It is significantly more than the rest of the world. For example: as a Californian who used a typical 15 kilowatt hours of energy a day, this means my entire home could have been fully solar powered by just 2 square meters – or about 3 feet by 6 feet – of solar panels in Saudi Arabia!

And Saudi Arabia has about 2 trillion square meters able to produce 14 trillion kilowatt hours of solar energy every sunny day – that is enough to power the world.

But of course, no country wants to be entirely devoted to energy production, least of all one that is still making good money from digging up oil, but it is indicative of the kind of money the Kingdom could be earning from solar exports rather than oil exports.

Just as it earns its vast income from oil now, it could equally well earn a similarly vast income from solar in the future. And for vast eons of time.

Transitioning to solar from oil would take an initial investment in the infrastructure, and then would yield an income stream regardless of fuel depletion, because solar is there for the long run, unlike the oil which is getting harder and harder to get out of the ground.

But it is Saudi Arabia itself which is in the best position in the world to make that transition and invest in a replacement for oil. With oil prices at $102 a barrel at today’s market price, the Saudis have over $30 trillion in underground assets.

With that much money in huge (but depleting) assets in petroleum and natural gas reserves, now is the time that Saudi Arabia should invest and become the world’s largest producer of green solar energy.

Saudi Arabia could export solar for centuries either as electricity into the Desertec grid, or as hydrogen fuel, using its tankers and pipelines.

Desertec, which will be shipping billions of kilowatt hours of desert solar energy across to Europe in the near future is becoming a reality in more MENA region nations with the addition of Morocco, Tunisia and Egypt, but the Saudis are not members of the visionary project.

Even though; unlike its poorer neighbors, it has tremendous financial assets – enough to become a leader in the project along with the giant German energy companies RWE and E.On – because it could self-fund its own Desertec infrastructure investment.

With over 250 hours of sunshine each month, Saudi Arabia is ideally located to make the most of solar power.

It even has the infrastructure already in place to be a leader in the solar-powered hydrogen economy of the future. Increasingly hydrogen researchers are turning to sustainable long term sources – wind or solar – for hydrogen production.

Solar powered hydrogen could be transported in the same pipeline and tanker infrastructure that now moves our climate-destroying oil energy around the world.

Saudi Aramco – 100% owned by the Kingdom of Saudi Arabia – through its affiliate, Vela Marine International Ltd, owns and operates the world’s second largest tanker fleet to help transport its crude oil production, which amounted to 3 billion barrels a year. It is a world leader in exploration, producing, refining, distribution, shipping and marketing.

Most of this infrastructure and expertise could be repurposed to transform Saudi Arabia into a solar hydrogen economy.

This infrastructure could be re-engineered to become a gigantic carrier fleet for hydrogen made with sustainable solar energy and shipped worldwide. New solar infrastructure could be added, as it has begun to do in making polysilicon from its sand.

It is Saudi Arabia that holds the key, with its unique combination of natural and financial resources, to creating a huge long-term future for the world that is based on a sustainable permanent source of energy: our sun.

UAE, KSA evolving into solar powerhouses

by Utilities ME Staff on Sep 3, 2013

The UAE and Saudi Arabia have emerged as the biggest markets among GCC states for the deployment of solar power, accounting for most of the projects. The six GCC countries altogether have sanctioned solar power installation projects worth approximately US $155bn, which will generate more than 84 GW of power when complete in 2017.

The Gulf countries will be addressing some of the main challenges related to the deployment of energy projects in desert terrain, at a high-level industry summit, called Gulf Sol 2013, taking place at the Dubai International Exhibition Centre from September 3 to 5. The event will feature government and private sector companies discussing ways of effective deployment of solar projects while also showcasing some of the latest international technologies.

At a press conference in Dubai, Derek Burston, director of the UK-based Bowmedia, organisers of Gulf Sol 2013, summarised the growth of the GCC photo-voltaic market as 'phenomenal'. "Over the years, solar power has been acknowledged as the most promising source of renewable energy and GCC governments have demonstrated their keenness to shift from traditional energy sources to these low-cost and abundant alternatives," he said.

"Direct radiation in many Middle Eastern countries exceeds 6 kWh per square metre per day, making for excellent solar potential. In addition, recent decreases in the costs of solar technologies coupled with rising electricity demand in these growing nations, if coupled with the right policies, could make the region a hub for solar expansion," Burston added.

The Emirates Solar Industries Association (ESIA) estimates that the key MENA markets to adopt solar power will be Saudi Arabia, Jordan, the UAE, Kuwait as well as Morocco. All of these countries have potent economic reasons for adopting solar technologies, and none of these nations have been directly affected by recent unrest.

Speaking at the press conference, Marc Norman, director of Emirates Solar Industries Association, said: "The economics of switching to solar energy in the Middle East is ever more compelling. With oil prices increasing, and solar technology costs plummeting, it is time for governments in the Middle East to turn talk into action."

Gulf Sol 2013 assumes added significance given that Abu Dhabi has set a goal of generating 7 per cent of its electricity from renewable sources by 2020 and the state-owned renewable energy company, Masdar, has announced that it will invest up to US $1.63bn in alternative energy schemes alongside the UK's Green Investment Bank (GIB). Masdar is currently evaluating solar thermal technology at its Masdar City project and has installed a field of TVP solar thermal panels as a pilot project.

On the other hand, Saudi Arabia, the world's largest oil producer, hopes to double its installed electricity capacity by building 54GW of renewable energy (as well as 17.6 GW of nuclear power) by 2032, of which 41 GW will obtained from the sun. Riyadh in Saudi Arabia currently boasts the world's largest solar thermal plant at 36,300 square meters, with commissioning announced in April 2012. The plant provides hot water for an estimated 40,000 students at Princess Noura Bint Abdulrahman University for Women.

Another major project in the region is Dubai's Mohammed bin Rashid Al Maktoum Solar Park, which aims for 1GW of PV and CSP generation by 2030. The US $3.2bn, 48sqkm park is the personal project of His Highness Sheikh Mohammed Bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai.

Masdar Opens First Baseload Solar in Spain – Gemasolar

Posted on October 5, 2011 by Susan Kraemer

Now Masdar builds solar with a 75% capacity factor, almost as much as nuclear

Masdar, the holistic and progressive renewable energy company from the UAE’s capital Abu Dhabi, and SENER, a leading engineering and construction firm in Spain have formed a joint venture, Torresol Energy, that just inaugurated their Gemasolar Concentrated Solar Power (CSP) project; the first commercial plant in the world to use molten salt thermal storage in a central tower configuration using a heliostat, which will give it a capacity factor of 75%, which is almost on a par with nuclear plants.

Gemasolar is the first of three projects that the newly formed partnership has financed at $1.4 billion US. Raising this amount for first of its kind technology at commercial scale shows what Masdar and SENER are jointly capable of as leaders in strong, credible solar technology.

The first of the three plants, the 20 MW Gemasolar project in Fuentes Andalucía, Spain, will power 100 percent of 27,500 Spanish households’ electricity needs, all day and most of the night, under a 25-year regulated tariff by the Spanish Government.

Storing the heat produced by the solar reflectors will enable the plant to supply energy to the grid on demand for at least fifteen hours a day, because molten salt can retain 99% of the heat stored in it for up to 24 hours.

Gemasolar will be the first commercial plant in the world to use molten salt both as the transfer fluid and the thermal storage in a central tower configuration using a heliostat field of mirrors to reflect the sun. (Molten salt storage with parabolic trough CSP has been only very recently pioneered, too.)

It will produce a net total of over 110 gigawatt-hours a year operating for a total of 6,450 hours a year at full capacity, the equivalent of a coal plant burning 89,000 tons of lignite. The plant is expected to save more than 30,000 tonnes of CO2 emission a year, helping Spain contribute to Europe’s 2020 climate and energy targets which aim to reduce greenhouse gas emissions by 20%.

Two thousand six hundred and fifty two sun-tracking heliostats, that took seven months to build, are arranged in concentric rings around the tower, with the furthest away situated at a distance of about one kilometer. Each has a mirror surface of 120 square meters.

Because salt is the transfer fluid (rather than oil) it can reach operating temperatures of over 500°C, much hotter than plants with parabolic trough technology using oils. These higher temperatures in turn generate hotter, pressurized steam in the turbine, which significantly increases the plant’s efficiency. Its commercial operation is expected to lead the way for other central tower plants with molten salt receiver technology, an efficient system that improves the dispatchability of electric power from renewable sources.

Masdar CEO, Dr Sultan Ahmed Al Jaber, told Business News that the project represents another of its milestones in an endeavor to build bridges with like-minded nations to address climate change. “Abu Dhabi aims to build bridges with like-minded nations to address the world’s greatest challenges, such as energy security, climate change mitigation, and sustainable human development” he said.

“Today is an important milestone in this endeavor. Masdar is working with international partners to develop and deploy the most recent scientific and technological innovations, increasing the role of renewable energy as part of a diversified energy. In this way, we will build on the UAE’s existing international role as an energy exporter by also becoming a global provider of future energy knowledge and expertise.”

Understandably, given this achievement, Gemasolar won the ‘Commercialized Technology Innovation of the Year’ and the Ruban d’Honneur title in the prestigious European Business Awards.
