Wrightbus is a bus manufacturer based in Northern Ireland. The company has a long history and is known for producing a variety of buses, including single-deck, double-deck, and articulated buses. Wrightbus has significantly contributed to the public transportation industry, particularly in the United Kingdom and other parts of the world.

Wrightbus has been a pioneer in the development of zero-emission buses. In 2018, the company unveiled the world's first hydrogen double-decker bus, the StreetDeck Hydroliner. It is equipped with a Hydrogen Fuel Cell power train and its battery pack can store up to 48KWh which allows the bus to travel up to 450km. It was designed to meet the demands of both bus drivers and passengers. The bus has been developed as part of the JIVE project funded by the European Union.

The StreetDeck Hydroliner is a significant step forward in developing zero-emission buses. It is a clean, efficient, and practical solution for urban transport. Its long range and fast refueling times make it well-suited for use on busy city routes.
