Kochi Airport To Deploy Hydrogen Buses First

(MENAFN- The Arabian Post)

Cochin International Airport Ltd has begun the procurement process for hydrogen fuel cell electric buses, positioning the Kochi hub to operate what is being described by officials as the country's first airport-based fleet powered entirely by hydrogen. The move places ground transport at the airport within a wider transition to low-emission mobility and aligns with Kerala's push to build a hydrogen ecosystem tied to national climate and energy goals.

The plan covers the purchase and operation of three hydrogen fuel cell buses to handle airside passenger movement, a segment traditionally dominated by diesel vehicles. Airport authorities say the buses will be deployed on routes linking terminals and remote aircraft bays, where stop-start driving and idling make emissions reductions particularly challenging. The project is being executed by Cochin International Airport through its airport operating company, which has already gained global attention for running entirely on solar power.

The initiative forms part of the Kerala Hydrogen Valley programme, a state-led framework intended to aggregate demand, anchor pilot projects and attract private investment into hydrogen production, storage and end-use. State officials describe the airport deployment as a visible demonstration use case that can validate hydrogen technology in public transport settings and reduce perceived risk for other operators. The hydrogen valley concept is designed to link generation from renewable sources with consumers such as mobility providers, ports and industrial users, building scale over time rather than relying on isolated pilots.

At the national level, the project sits under the National Green Hydrogen Mission, which targets the creation of a domestic hydrogen market and seeks to lower the cost of green hydrogen through incentives, demand aggregation and infrastructure support. The mission, backed by the Government of India, prioritises applications where hydrogen can displace fossil fuels in hard-to-abate sectors, including transport, fertilisers and refining. Aviation ground operations have emerged as a promising niche because fleets are centrally managed and refuelling can be controlled within secure perimeters.

Airport officials say the buses under procurement will be fuel cell electric vehicles, generating electricity onboard through a chemical reaction between hydrogen and oxygen, with water vapour as the only tailpipe emission. Compared with battery-electric buses, hydrogen vehicles offer faster refuelling and longer range, features considered important for continuous airport operations. The buses will require dedicated refuelling infrastructure within the airport campus, and plans include on-site safety systems and training for personnel handling hydrogen.

Industry analysts note that hydrogen mobility in the country remains at an early stage, with high vehicle costs and limited refuelling networks acting as constraints. Fuel cell buses can cost several times more than diesel equivalents, and the economics depend heavily on access to competitively priced green hydrogen. Kerala's approach has been to pair demand-side pilots with efforts to scale renewable-powered hydrogen production, reducing reliance on imported fossil fuels while addressing local air quality concerns.

Kochi airport's history of renewable adoption has been cited by policymakers as a reason it was selected for the hydrogen bus deployment. The airport became the first fully solar-powered airport in the world and has since expanded its renewable portfolio, including battery storage and electric vehicle charging for landside transport. By extending decarbonisation to airside mobility, the airport is attempting to address a segment that contributes to operational emissions but often receives less public scrutiny than aircraft themselves.

Transport experts caution that the success of the hydrogen buses will depend on operational reliability and lifecycle emissions, not just tailpipe performance. Green hydrogen must be produced using renewable electricity to deliver meaningful climate benefits, and storage and distribution losses need to be minimised. Safety protocols will also be closely watched, given hydrogen's flammability, although proponents point out that fuel cell vehicles have been operating in several countries under stringent standards.

The Kochi deployment is being monitored by other airports and urban transport authorities exploring alternatives to diesel. Several metropolitan transport agencies have trialled electric buses, while hydrogen has so far been limited to a handful of demonstration projects in public transport. If the airport fleet performs as expected, officials believe it could accelerate adoption in other controlled environments such as ports, logistics hubs and industrial campuses.
