Bulgarian scientists work on a hybrid trolleybus that can be independent of the contact network, traveling up to 100 kilometers of electricity from its own sources, developing advanced batteries and supercapacitors, seeking new technologies for storing and converting renewable energy and experimenting with ways to capture and atmospheric carbon dioxide conversion. These are just part of the projects, part of the National Science Program “Low Carbon Energy for Transport and Households – E +”. The hybrid trolleybus will be based on a 13-foot-tall, older 13-foot-tall Icarus, which will house a fuel cell and battery. Their role is to provide electricity to the motor, which makes the trolley independent of the contact network.
