Ampaire, a California startup developing hybrid-electric aircraft, has raised $19 million in Series B funding, according to AeroTime.

DiamondStream Partners led the round, which the report says brings Ampaire's total funding to $68 million. Investors include venture arms of International Airlines Group and Alaska Airlines. Ampaire plans to use the capital to advance commercial readiness of its AMP-H570 hybrid-electric propulsion system, which is being retrofitted into Cessna Grand Caravan aircraft.

The company says the resulting Eco Caravan is intended to halve fuel consumption.
