Boeing is investing in Accion technologies , a Boston start - up that develops electric propulsion satellite technology . The investment will drive development of satellite propulsion for low and medium earth orbit and deep space . Accion has created a tiled ionic liquid electrospray ( TILE ) system , a propulsion system that boosts the efficiency and flexibility of satellites and vehicles in space . TILE uses an ionic liquid propellant and has been described by Accion as a lightweight , smaller and more cost - effective alternative to traditional ion engines .
