Recharge Wrap-up: Porsche buys stake in carbon fiber partsmaker, Formula E runs on solar

The US Department of Energy is providing $35 million in new funding for fuel cell and hydrogen technologies. The money will fund projects to advance technology and speed up adoption of fuel cell applications like light-duty vehicles. Categories for possible projects include deployment of fuel-cell electric hybrid vehicles, mobile refueling and one called "Crosscutting: America's Climate Communities of Excellence." Other possible projects include research and development for hydrogen production, delivery and fuel cell manufacturing. Read more from the DOE. Porsche will buy a 25.1-percent stake in carbon fiber parts manufacturer Capricorn Composite GmbH. Capricorn has provided parts for Porsche's LMP1 racecar and 918 Spyder. The deal will give the automaker better access to the lightweight material going forward, and will "build on joint work over many years in the motor-sports industry and secure the future," according to Porsche. Porsche's parent company Volkswagen owns almost 10 percent of Capricorn's competitor SGL Carbon SE, but an expansion of that ownership could be thwarted by BMW, which controls more of SGL's stock.

Florida Power & Light (FPL) will provide the electricity the cars will be using for the race on March 14, and its Martin Next Generation Solar Energy Center provided the electricity the cars used during the announcement event. "Our partnership with Formula E and the Miami ePrix is another example of our commitment to advancing zero-emissions solar energy and the use of electric vehicles in Florida," says FPL President and CEO Eric Silagy. FPL currently operates two other solar plants, with plans to install 1 million solar panels at three more power plants by the end of next year. Read more at Domestic Fuel.

Porsche 919 Hybrid revives Porsche's factory Le Mans efforts

After months of teasing with camouflaged testers, Porsche has finally unveiled its prototype entry for the 2014 World Endurance Championship, the 919 Hybrid. Porsche, you may recall, hasn't had campaigned a factory team at Le Mans in years, so the 919 is nothing less than their recommitment to endurance racing.
Combining a 2.0-liter V4 (yes, a V4) that revs to 9,000 rpm, the 919 produces around 500 horsepower with a pair of energy recovery systems. The first system recovers the heat energy from exhaust gasses as they pass through an electrical generator, while the second system is a bit more familiar. Using a setup similar to what is found on the production 918 Spyder, a generator on the front axle recovers kinetic energy from the brakes, which is subsequently stored in a battery system. That power can then be sent to the front wheels at the driver's command, effectively turning the 919 into an all-wheel-drive racecar.
Despite these various forms of motivation, Porsche doesn't claim to be seeking outright power supremacy, with Chairman Matthias Müller saying, "In 2014, it will not be the fastest car that wins the World Endurance Championship series and the 24 hours of Le Mans, rather it will be the car that goes the furthest with a defined amount of energy. And it is precisely this challenge that carmakers must overcome. The 919 Hybrid is our fastest mobile research laboratory and the most complex race car that Porsche has ever built."

2015 24 Hours of Le Mans live race report

Check back regularly for more race updates every few hours. No, you don't need to stay up for the entire 24 Hours of Le Mans, but if you want to catch any of the action, Autoblog friend Reilly Brennan has a handy guide. And to keep you up to speed on the latest race events, we'll be posting live from Le Mans with regular race reports.Hour 1: Five laps in, Audi breaks up the three Porsches at the front, with the #19 919 Hybrid, driven by Nico Hulkenburg, passed by all three R18s. Hulkenburg eventually took back fifth position only to fall back again after the first pit stop. Meanwhile, clutch trouble kept the #23 Nissan GTR-LM in the pits until 15 minutes into the race. The other two Nissans were forced to start at the back of the grid after failing to the meet the 110 percent qualifying speed regulation. At the end of the first hour, just 7.5 seconds separated the first six cars. Then the factory team #92 Porsche GTE car caught fire, with the the #13 Rebellion P1 car taking frontal damage in the ensuing carnage. With the safety car out, the field is once again bunched up.Hour 2: The slugfest between Audi and Porsche continues, with neither side backing off. Halfway through the second hour the #7 R18 passes both leading Porsches for the top position. After another round of pits stops Porsche regains the lead until lap 30, when the Audi overtake once again and quickly pulls out a three-second gap. Nico Hulkenburg passes the other two Audis to join his Porsche teammates. At the beginning of the third hour it's Audi #7, Porsche #17, #18, and #19, followed by Audi #8 and #9. 33 seconds separates this group, with Toyota a minute back from the front car.Hour 3: On track the action refuses to stop. Although it's early, Audi is looking strong with the overall lead in the #7. What's more is that the Audis run four stints per set of tires, while the Porsche cars have to change rubber every third stop. But after a quick refueling, the lead R18 gets a tire puncture and comes back in 3 laps later, allowing Porsche to take over the top two spots. Then as the hour closes out a yellow flag causes traffic to bunch up and the #8 Audi gets stuck with nowhere to slow down. Driver Loic Duval dives for the side of the road but hits the guard rail and careens across the track, damaging the front and rear bodywork. The rest of the car is still intact, though, and once in the pits Audi replaces the entire front and rear of that in only three minutes.
