If hybrid cars can cut CO2 emissions on the road, can hybrid-electric planes do the same in the air? 

NASA is exploring that possibility, announcing this week two contracts to aviation startup Electra. The company claims it can meet NASA’s goal of reducing airliner fuel use by 60% to 80% by 2035 with a hybrid design that features generators powering motors to drive a large number of propellers. While this may sound like a convoluted way to power an airliner, the company claims it ultimately requires far less fuel than a traditional plane. 

Electra is already flying a two-seat test plane with this kind of system and will debut a nine-seater with a 380-mile range this week. It’s now partnering with American Airlines, Honeywell, Lockheed Martin, MIT, and the University of Michigan to guide the design and scale up the tech to airliners.

Electra’s grants, totaling about $3.5 million, are part of the $11.5 million, to four companies and one university for the first phase of its Advanced Aircraft for Sustainable Aviation (AACES) 2050 program. First announced in August 2023, AACES challenges companies to propose aircraft concepts that could help bring passenger and cargo plane emissions to zero by 2050.

The aviation industry has long touted zero-emission fuels (for example, jet fuel made from biomass, or hydrogen produced with green electricity) as the ultimate climate solution. It’s easier to make enough of these fuels if new planes need a lot less of them—hence NASA’s challenge to Electra and the other winners to develop radically more-efficient designs.

The case for electric-powered planes

A number of companies are developing electric airplanes, but most are for short-range air taxi services. Toyota-backed Joby Aviation, for example, promises to put a four-passenger plane into service as soon as 2025. Powered 100% by heavy batteries, packing about 1/40th as much energy per pound as jet fuel, Joby’s plane can fly 100 miles per charge.

Electra stands out as one of the few companies, alongside Sweden’s Heart Aerospace and Ampaire and Whisper Aero out of the U.S., testing different hybrid concepts to dramatically extend range. (NASA has also been testing hybrid tech with other companies.) Electra and its allies’ initial concept for NASA is a 114-seat airliner that can fly nearly 3,300 miles, says Electra’s vice president and general manager, JP Stewart. But he says the tech can scale to NASA’s largest target: carrying about 300 people up to around 8,600 miles.

Electra’s take on hybrid technology is called a “series hybrid.” On a traditional plane, each propeller (or jet engine) requires a big, expensive turbine that burns jet fuel. By using turbines to power generators instead, Electra can run more props using lightweight electric motors. Electra’s initial sketch has five propellers across each wing (plus three in the tail), which the company says can improve airflow and boost the wing’s ability to lift the plane—tech that’s already working on its two-seat prototype. For its NASA proposal, Electra envisions an airliner that uses this hybrid tech and a new design of the fuselage (the tube carrying passengers) to take off with smaller wings, which will produce less drag and save fuel in flight.

Another benefit of hooking a turbine to a generator, says Stewart, is that the turbine can run at its most-efficient speed throughout the flight. Airplane engines have to be very flexible, gunning it on takeoff and landing and running less intensely when the plane is cruising in the air. Turbines that power the propellers directly don’t have the flexibility to do both tasks efficiently; electric motors do. Finally, by adding batteries to the mix, the plane can use a smaller turbine that needs to produce just enough power for cruising, says Electra. For takeoff and landing, battery packs join in to provide the extra oomph only when needed.

Electra’s concept is just one of several ideas NASA has given the green light to. Another contract winner, JetZero, has proposed a liquid hydrogen-powered, “blended wing body” concept for a jetliner or cargo plane that ditches the traditional design of a metal tube with wings and a tail. Instead, it has a tail-less, triangular shape that looks a bit like a B2 Stealth Bomber and promises major fuel savings. 

Other winners include Georgia Institute of Technology, Pratt & Whitney (part of the RTX conglomerate), and Boeing-owned Aurora Flight Sciences, which are working on several engine and body technologies. (Aurora founder John Langford went on to found Electra in 2020.)

The task now for Electra, JetZero, and other winners is to produce a final airplane design in 18 months. Getting real planes in the air will take many more years.

Renew Home says they're building a "virtual power plant" in Texas by "enabling homes to easily reduce and shift the timing of energy use." Thursday they announced a 10-year project distributing hundreds of thousands of smart thermostats to customers of Texas-based power utility NRG Energy, starting next spring. (Bloomberg calls them "AI-enabled thermostats that use Alphabet Inc.'s Google Cloud technology.") The ultimate goal? "Create a nearly 1-gigawatt, AI-powered virtual power plant" — equivalent to 1.9 million solar panels, enough to power about 200,000 homes during peak demand. One NRG executive touted the move as "cutting-edge, AI-driven solutions that will bolster grid resilience and contribute to a more sustainable future." [Residential virtual power plants] work by aggregating numerous, small-scale distributed energy resources like HVAC systems controlled by smart thermostats and home batteries and coordinating them to balance supply and demand... NRG, in partnership with Renew Home, plans to offer Vivint and Nest smart thermostats, including professional installation, at no cost to eligible customers across NRG's retail electricity providers and plans. These advanced thermostats make subtle automatic HVAC adjustments to help customers shift their energy use to times when electricity is less constrained, less expensive, and cleaner... Over time, the parties expect to add devices like batteries and electric vehicles to the virtual power plant, expanding energy savings opportunities for customers... Through the use of Google Cloud's data, analytics, and AI technology, NRG will be able to do things like better predict weather conditions, forecast wind and solar generation output, and create predictive pricing models, allowing for more efficient production and ultimately ensuring the home energy experience is seamless for customers. Google Cloud will also offer "its AI and machine learning to determine the best time to cool or heat homes," reports Bloomberg, "based on a household's energy usage patterns and ambient temperatures." It was less than a year ago that Renew Home was formed when Google spun off the load-shifting service for its "Google Nest" thermostats, which merged with load-shift management startup OhmConnect. Bloomberg describes this week's announcement as "Three of the biggest names in US home energy automation... coming together to offer some relief to the beleaguered Texas electrical grid." But they point out that 1 gigawatt is roughly 1% of the record summer demand seen in Texas this year. Still, "The entire industry has been built to serve the peak load on the hottest day of the year," said Rasesh Patel, president of NRG's consumer unit. "This allows us to be a lot more smarter about demand in shaving the peak."
