A Potentially Cheap Way to Store Solar | MIT Technology Review

A Potentially Cheap Way to Store Solar | MIT Technology Review | Solar Energy projects & Energy Efficiency | Scoop.it
A simple, cheap device turns sunlight into hydrogen fuel.

If solar power is to become a primary source of electricity around the world, we’ll need cheap ways to store energy from the sun when it isn’t shining. A paper published in the journal Science this week reports a major step toward such a system. Researchers have developed a device that cheaply and efficiently converts the energy in sunlight into hydrogen, which can be used as a fuel and is easily stored.

Solar energy: a sunflower solution to electricity shortage

Solar energy: a sunflower solution to electricity shortage | Solar Energy projects & Energy Efficiency | Scoop.it

Computer giant IBM last week revealed the prototype of its advanced solar electricity generators: a 30ft-high concrete “sunflower” fitted with wafer-thin aluminium mirrors and a maze of tiny tubes for carrying coolant through the heart of each device. The machines, which will be built in conjunction with the Swiss company Airlight Energy, can convert 80% of the sun’s radiation into electricity and hot water, it is claimed, with each generating 12 kilowatts of electricity and 20kW of heat on a sunny day, enough to supply several homes.

Solar City and Tesla Hatch a Plan to Lower the Cost of Solar Power

Solar City and Tesla Hatch a Plan to Lower the Cost of Solar Power | Solar Energy projects & Energy Efficiency | Scoop.it
Tesla and Solar City say their vast manufacturing operations will make solar the cheapest source of electricity in the United States.

Both companies’ manufacturing plans are ambitious but also risky, given the recent track record of U.S. energy companies, and because unexpected technology advances could quickly render the components produced in those plants outmoded. In the case of solar panels, there is also the continued threat of heavily subsidized competition from China. For both companies, the bet is that rapidly growing demand will allow new economies of scale to lower the cost of manufacturing these components, which in turn will lower the cost of solar power.

Stephane Bilodeau's curator insight, September 23, 8:04 AM

At an event hosted in New York this week by Solar City, CEO Lyndon Rive and chairman Elon Musk announced that within five to 10 years every set of solar panels that Solar City installs will come with a battery pack to help deal with the intermittency of solar power—one of the key factors limiting its use. Musk says his company Tesla Motors will supply at least some of those batteries.

(...)

Rive and Musk, who are cousins, also said at the New York event that within the same time frame electricity from solar power would become cheaper in the U.S. than power produced from natural gas. To meet that target, the pair both plan to build two major manufacturing operations that will feed off each other. One of Musk’s other companies, Tesla Motors, announced plans earlier this month to build a vast factory for producing lithium-ion batteries in Nevada (see “Does Musk’s Gigafactory Make Sense?”). This factory will supply batteries for its electric vehicles as well as to Solar City. While some lithium-ion batteries and solar cells are made in the U.S. today, the vast majority are made in Asia.

China Surpasses EU in Per-Capita Pollution for First Time

China Surpasses EU in Per-Capita Pollution for First Time | Solar Energy projects & Energy Efficiency | Scoop.it

China surpassed the European Union in pollution levels per capita for the first time last year, propelling to a record the worldwide greenhouse-gas emissions that are blamed for climate change. 

The findings led by scientists at two British universities show the scale of the challenge of reining in emissions damaging the climate. They estimate that humans already have spewed into the atmosphere two-thirds of the fossil-fuel emissions allowable under scenarios that avoid irreversible changes to the planet.

The Untapped Power of Solar Data : Greentech Media

The Untapped Power of Solar Data : Greentech Media | Solar Energy projects & Energy Efficiency | Scoop.it

Why we need to leverage big data to grow solar. 

Last year, the global solar industry surpassed 100 gigawatts of cumulative installed capacity, and it is quickly approaching 100 gigawatts of annual deployment. While solar has rapidly scaled up in the past ten years, there are several hurdles to clear before solar can make its way into the mainstream. One of the industry’s biggest impediments is that its technology is still perceived as “new” and therefore risky by the more conservative financial community.

“One of the reasons why the private market isn’t doing much with clean energy now is that it doesn’t understand the technology and its potential,” said Douglass Sims

New molten salt solar plant starts operation | Solar Energy projects & Energy Efficiency | Scoop.it

Novatec Solar and BASF have commissioned a solar thermal demonstration plant based on a new type of molten salt technology, known as direct molten salt or DMS technology. The plant is located on the site of the solar thermal power plant PE1 in southern Spain. The plant uses inorganic molten salt as heat transfer fluid. Most solar thermal power plants currently use heat transfer oils, which have a limited qualification temperature near 400 °C. Using inorganic salts as heat transfer fluid allows temperatures above 500 °C, resulting in a significant increase in power yield.

It’s always interesting to attend conferences in far away places because of the change in perspectives. At the World Energy Security Forum (whose organizers I advised) in Johannesburg, there was the usual discussion of different energy sources and their roles, but also senior politicians with much experience in governing.

A very perceptive remark was made by former Prime Minister Odinga of Kenya, who, discussing NGO opposition to some energy projects in Africa, remarked, “You can’t have grandchildren if your daughter remains a virgin.” Similarly, he added that Africans wanted to conserve their environment, but not as a virgin environment.

Micropower now produces about one-fourth of the world’s total electricity. In a cover story and article 14 years ago about the emergent disruption of utilities, The Economist’s Vijay Vaitheeswaran coined the umbrella term “micropower” to mean sources of electricity that are relatively small, modular, mass-producible, quick-to-deploy, and hence rapidly scalable—the opposite of cathedral-like power plants that cost billions of dollars and take about a decade to license and build. His term combined two kinds of micropower: renewablesother than big hydroelectric dams, and cogeneration of electricity together with useful heat in factories or buildings (also known as combined-heat-and-power, or CHP).

Sun-powered desalination for villages in India

Sun-powered desalination for villages in India | Solar Energy projects & Energy Efficiency | Scoop.it
Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water -- and much of that area is not served by an electric grid that could run conventional reverse-osmosis desalination plants. Sun-powered desalination could deliver clean water for off-grid villages.

Now an analysis by MIT researchers shows that a different desalination technology called electrodialysis, powered by solar panels, could provide enough clean, palatable drinking water to supply the needs of a typical village.

PV plants in Germany are more profitable than expected

PV plants in Germany are more profitable than expected | Solar Energy projects & Energy Efficiency | Scoop.it

PV systems in Germany are regularly generating higher yields than expected. An investigation by Fraunhofer ISE links these higher yields to an upward trend in solar radiation, pointing out that the current radiation level in Germany is considerably higher than the average values of the last 30 years. As these average values have generally been used in yield predictions up to now, actual PV system yields are exceeding their forecasts by approximately five percent, making them more cost-effective than anticipated. To take this effect into account, Freiburg researchers have adapted their quality assurance services for PV systems and are now basing their yield predictions on solar radiation data from the last ten years.
