Optical 'nanocavity' to boost light absorption in semiconductors; improve solar cells, cameras and more

Put simply, an optical cavity is an arrangement of mirrors that allows beams of light to circulate in closed paths. These cavities help us build things like lasers and optical fibers used for communications. Now, an international research team pushed the concept further by developing an optical "nanocavity" that boosts the amount of light that ultrathin semiconductors absorb. The advancement could lead to, among other things, more powerful photovoltaic cells and faster video cameras; it also could be useful for splitting water using energy from light, which could aid in the development of hydrogen fuel.

Rail Projects Boosting Oil Flow to California Refineries

cotton98_159940170259California, the third-biggest refining state in the U.S., is about to see a flood of oil by rail from places such as Canada andNorth Dakota as suppliers seek to tap a market isolated from the rest of the country. The Western U.S. may bring 500,000 barrels of light oil by rail a day in 2015 as the region’s refiners seek to replace shrinking output in California and Alaskaand more costly foreign imports,Mark Smith, Tesoro Corp. (TSO)’s vice president of development, supply and logistics, said at a conference yesterday in Glendale, California. California refineries can run 1.63 million barrels a day, the most in the U.S. after Texas and Louisiana, government data show.

Is Utility 2.0 A Forecast Or A Post-Mortem?

For the last six months, the energy news sphere (perhaps led by the Edison Electric Institute) has been rife with a discussion about the threat to the utility business from distributed energy like local solar, as their customers shift to getting their own power from nearby renewable resources.  Reports and news stories – e.g. “Adapt or Die” – suggest changes to the electric utility business model are imminent as power generation shifts from massive to medium scale and from remote to local. For some utilities, this discussion is not a forecast, but a post-mortem.

How The US Is Driving Down Utility-Scale Solar Costs (CHART)

The US government has announced that the US solar industry is more than 60 per cent of the way to achieving cost-competitive utility-scale solar photovoltaic (PV) electricity, an achievement it credits partly to support from the Energy Department’s SunShot Initiative. SunShot was set up in 2011 to re-establish US leadership in the solar marketplace by partnering with industry, universities, local communities and the Department’s National Laboratories to aggressively drive down the cost of generation. To achieve this goal, says the DoE, SunShot aimed for a price of $0.06 per kilowatt-hour (KWh) – a target that would make solar-generated power fully cost-competitive with traditional energy sources by the end of the decade.

WTI Crude Rises on Cushing Supplies

West Texas Intermediate crude rose for a second time this week, narrowing its discount to Brent, as inventories dropped at Cushing, Oklahoma. Prices advanced 0.7 percent. Stockpiles at the futures’ delivery point slid 1.08 million barrels last week, the Energy Information Administration said. Supplies have shrunk since TransCanada Corp. (TRP) said in January that it began using the southern leg of the Keystone XL pipeline to move oil to Texas from Cushing. Total crude stocks increased less than forecast.

National Renewable Energy Subsidy Schemes Nearing An End In The EU

clowds-on-the-horizon-photo-by-Sigfrid-LundbergThe national renewable support schemes in the EU are on the verge of a major overhaul. National governments will soon not be allowed anymore to limit renewables subsidies to domestic producers: they will have to treat all EU-based producers alike. This at any rate is the very likely outcome of a court case now before the EU Court of Justice, says Peter Niermeijer, Secretary-General of RECS International, an organisation that promotes pan-European trade in renewable energy, in an interview with Energy Post. According to Niermeijer, the court decision, expected in a matter of months, will have far-reaching political consequences: it will force an end to the fragmentation of national energy policies in the EU and give a big push to the integration of the EU energy market. It will also radically undermine existing support schemes, including the laws which form the basis of the German Energiewende.

Riversimple Fuel Cell Car Project Continues to Plod Along

Riversimple Fuel Cell CarPeople are getting more and more excited about green automobiles, so it was kind of surprising to see such a neutral reaction to the Fuel Cell Car by Riversimple. While this project has a very interesting slant from other cars that we have seen in this niche, it was met with a very lukewarm reception and things have not really heated up on in yet. However, the Riversimple Fuel Cell Car continues on and will hopefully be available for release in the next few years.
