As I write in The New York Times on Friday, it’s spring cleaning at three renewable energy firms as top executives depart SolarReserve, Clipper Windpower and Aurora Biofuels:

The past week has brought a spate of executive departures at renewable energy startups, with the president of SolarReserve, a power plant builder, and the chief executives of Clipper Windpower and Aurora Biofuels stepping down.

Terry Murphy, a rocket scientist who co-founded SolarReserve after a career at United Technologies’ Rocketdyne division, has started a new venture called Advanced Rocket Technologies in Commercial Applications, or ARTiCA. The firm will evaluate green technologies for entrepreneurs and investors, according to Mr. Murphy.

Mr. Murphy and SolarReserve both said the departure was voluntary. “With the company solidly executing on its business strategies, Mr. Murphy has transitioned to an external role in providing developmental expertise to other early stage clean energy companies,” wrote Debra Hotaling, a spokeswoman for SolarReserve, in an e-mail message.

When Mr. Murphy left Rocketdyne to start SolarReserve, the startup licensed Rocketdyne’s molten salt technology so that its solar power plants could store solar energy for use after the sun sets or on cloudy days.

“SolarReserve, in my opinion, is up and running on all four cylinders,” said Mr. Murphy.

“What I did at Rocketdyne and what I did at SolarReserve and what I’m looking at doing in the future is to sift through technologies to find those that can be commercialized.”

Mr. Murphy’s new firm will focus on technologies involving renewable energy, desalinization and sustainability, he said.

In The New York Times on Saturday, I write about utilities NV Energy and PG&E signing power purchase agreements to buy electricity from SolarReserve’s solar farms, which store the sun’s energy in molten salt to generate power at night:

Solar farms that would serve two Western utilities are planning to use technology that will generate electricity after the sun goes down, a move that could be a potential game-changer for the industry.

The two farms being planned by SolarReserve of Santa Monica, Calif., would store the sun’s energy in molten salt, releasing the heat at night when it could be used to drive a turbine and generate electricity. Two utilities, NV Energy in Nevada and Pacific Gas and Electric, Northern California’s biggest utility, would buy the power.

The sun’s intermittent nature has made large-scale solar farms most useful as so-called peaker plants that supply electricity when demand spikes, typically in the late afternoon on hot days. But the ability of SolarReserve to store the sun’s energy for use at night would be a step forward in technology.

“The energy storage characteristics were a key factor in our selection of the Tonopah solar energy project,” NV Energy’s chief executive, Michael Yackira, said in a statement. The utility will be able to draw electricity from the solar farm more or less on demand, which makes it easier to balance the load on the power grid.

NV Energy would buy power from the 100-megawatt Crescent Dunes Solar Energy Project being planned on federal land near Tonopah, Nev., about 215 miles northwest of Las Vegas.

“We’re expecting to put in 12 hours of storage, which allows us to move power within the day to meet peak requirements as well as to operate at full load,” SolarReserve’s chief executive, Kevin Smith, said of the Tonopah plant.

Ok, I’m exaggerating a bit in the headline above but we’re getting closer to solar farms that will provide baseload power, operating at night and under cloudy conditions. As I write on Tuesday in The New York Times:

The holy grail of renewable energy is a solar power plant that continues producing electricity after the sun goes down.

A Santa Monica, Calif., company called SolarReserve has taken a step toward making that a reality, filing an application with California regulators to build a 150-megawatt solar farm that will store seven hours’ worth of the sun’s energy in the form of molten salt.

Heat from the salt can be released when it’s cloudy or at night to create steam that drives an electricity-generating turbine.

The Rice Solar Energy Project, to be built in the Sonoran Desert east of Palm Springs, will “generate steady and uninterrupted power during hours of peak electricity demand,” according to SolarReserve’s license application.

So-called dispatchable solar farms would in theory allow utilities to avoid spending billions of dollars building fossil fuel power plants that are fired up only a few times a year when electricity demand spikes, like on a hot day.

SolarReserve is literally run by rocket scientists, many of whom formerly worked at Rocketdyne, a subsidiary of the technology giant United Technologies. Rocketdyne developed the solar salt technology, which was proven viable at the 10-megawatt Solar Two demonstration project near Barstow, Calif., in the 1990s.
