He said Chief Minister Abang Johari Openg must reveal the economic feasibility study and cost-effectiveness analysis of the proposed venture, including the construction of the multi-fuel refuelling stations and hydrogen buses.

“Abang Johari must be transparent and avoid wasteful and unnecessary government spending on megaprojects which do not benefit the people,” he said.

Yii was commenting on the Sarawak Economic Development Corporation’s plan to build six multi-fuel refuelling stations in the state.

The stations will be operating under the brand name Petros, the state-owned petroleum and gas company, which will offer conventional fuels, electric charging and hydrogen refuelling.

Yii said the cost of hydrogen cars is most likely beyond the reach of most ordinary Sarawakians.

“The government should look into investing into battery electric vehicles instead as 70% of our power comes from hydropower, which is renewable energy,” he said.

He said an electric vehicle could be charged using the power grid anywhere anytime, without investing in a costly hydrogen infrastructure and distribution network.
