Brazil receives request for 392.4 MW of PV
21. May 2013 | Applications & Installations, Global PV markets, Markets & Trends | By: Vladimir Pekic

Thirteen requests for regulatory authorization to develop and operate photovoltaic plants worth a total of 392.4 MW have been received last week, according to Brazil's national electricity regulator.

The notices about the received requests were published in Brazil’s state gazette Diário Oficial da União (DOU).

Solar energy developer Arigó Solar Energia SPE submitted a request for the registration of one photovoltaic project totaling 30 MW. The plant is to be developed in Pocinhos municipality, in Brazil’s northeast Paraíba state. The announcement was published by the Agencia Nacional de Energia Elétrica (ANEEL) in DOU on May 7.

In the same issue, ANEEL revealed that developer Solyes Geradora de Energia Ltda applied for registration for two photovoltaic plants: 30 MW Sol do Sertão XV and 30 MW Sol do Sertão XVIII, in Cônego Marinho municipality, in Minas Gerais state.

On May 9, the Brazilian regulator disclosed that Renova Energia, also submitted a request for registration for its 30.24 MW Caetité V photovoltaic plant, slated for construction in Bahía's Caetité municipality.

Finally, in the same DOU issue, ANEEL announced that CPFL Energias Renováveis, the third largest Brazilian electric utility, submitted requests for regulatory authorization for 10 new photovoltaic plants with a combined capacity of 302.4 MW. The plants will be developed in Ourolândia municipality, in the northeastern state of Bahia.

Lux Research sees doubling of PV market up to 2018
21. May 2013 | Applications & Installations, Industry & Suppliers, Markets & Trends | By: Shamsiah Ali-Oettinger

Lux Research has announced that the solar sector is on the recovery path, set to reach US$155 billion in 2018. The industry is expected to ramp up rapidly to 61.7 GW in 2018 after modest growth to 35 GW in 2013. This is according to the "most-likely scenario" put forth by the analysts. China is set to leapfrog to become the largest market.

The Lux Research report "Market size update 2013: Return to equilibrium" states that market forces will enable a turnabout in the photovoltaic sector to see a "healthy 10.5% compound annual growth rate (CAGR)". Lux Research sees this situation as a "rising from the ashes" for the sector that has been in the doldrums since 2011.

The analysts at Lux Research used a detailed levelized cost of energy (LCOE) analysis in 156 separate geographies to determine the viability and competitiveness of solar in each market.

U.S., China, Japan and India will take over where Germany and Italy have left off, driving global demand from 31 GW in 2012 to 62 GW in 2018. The U.S. is predicted to become the world's second largest market with an 18% CAGR to reach 10.8 GW of installations in 2018. China will lead the pack with an over 15% annual growth to reach 12.4 GW in 2018. The consolidation is already reducing global capacity and low prices will thus weed out uncompetitive manufacturers. With demand rising and warehouses emptying, the industry is likely to return to the state of equilibrium, within 12% of each other in 2015, says Lux Research.

Utility-scale installations are expected to grow the fastest to hit 19.9 GW in 2018 as developing markets start taking note of photovoltaics. This segment is the smallest in 2012 at 8.6 GW according to Lux Research. Commercial applications will be the leading segment globally with U.S. and Japanese markets going heavy on large rooftop installations.

Liquefied Air Could Power Cars and Store Energy from Sun and Wind
A 19th-century idea might lead to cleaner cars, larger-scale renewable energy.

By Kevin Bullis on May 20, 2013

Some engineers are dusting off an old idea for storing energy—using electricity to liquefy air by cooling it down to nearly 200 °C below zero. When power is needed, the liquefied air is allowed to warm up and expand to drive a steam turbine and generator.

The concept is being evaluated by a handful of companies that produce liquefied nitrogen as a way to store energy from intermittent renewable energy sources. Liquefied air might also be used to drive pistons in the engines of low-emission vehicles.

One company, Highview Power Storage of London, has raised $18 million and built a pilot plant that will use liquid air to store power from the grid. Highview has teamed up with Messer, the large industrial gas company, to help develop the technology. If all goes well, the U.K. government may fund the development of a larger plant that could establish its commercial viability. Meanwhile, the engineering consultancy Ricardo is developing two types of engines that could use liquid nitrogen, based on technology from a Highview Power spinoff called Dearman Engine.

Storage for the power grid is becoming more important as use of renewable energy increases. In the near term, natural-gas power plants and fast-responding storage technologies such as batteries can keep the grid stable (see “Wind Turbines, Battery Included, Can Keep Power Supplies Stable”). But if renewables are to reach a very large scale, or if we want to reduce the use of fossil-fuel backup power plants, technologies that can store hours’ or days’ worth of power will be needed.
