Landmark hydrogen hub supports Ark Energy green zinc ambitions

Investing in a thriving hydrogen economy in Queensland

Ark Energy is developing the SunHQ H2 hydrogen hub in Townsville, which will include a 1 MW hydrogen electrolyser, compressors, storage and refuelling infrastructure.  With a production capacity of up to 155 tonnes of green hydrogen a year, the hub is a key part of plans to enable the Sun Metals zinc refinery to become the first in the world to produce green zinc.

to green zinc production

Ark Energy is to be congratulated on its leadership in the hydrogen sector with SunHQ contributing to reducing emissions and supporting the reduction of carbon in the zinc supply chain.

Our investment

The CEFC has committed up to $12.5 million to Ark Energy Corporation to finance the production of green hydrogen at the Townsville SunHQ H2 hydrogen hub, through the Advancing Hydrogen Fund.

The investment will support the construction of hydrogen production and refuelling infrastructure for the Sun Metals zinc refinery, with green hydrogen produced from a 1 MW polymer electrolyte membrane (PEM) electrolyser powered by the 121 MWac Sun Metals Solar Farm.

Ark Energy will use this green hydrogen to advance the uptake of hydrogen-powered vehicles in the heavy-haulage industry. Affiliated company Townsville Logistics is expected to use the green hydrogen to decarbonise its heavy vehicle fleet operating between the Sun Metals Zinc Refinery and the Port of Townsville.  

Ark Energy is in the process of finalising SunHQ’s offtake solution and has the capacity to supply green hydrogen for a range of other customers. SunHQ will kickstart a thriving hydrogen economy in Queensland and facilitate further decarbonisation.  

The electric trucks will deliver zinc ore from Townsville Port to the Sun Metals zinc refinery where they will refuel with green hydrogen before transporting the refined zinc ingots to port in a 30 kilometre clean energy round trip.

TAFE Queensland will deliver hydrogen and renewables training to the Ark Energy workforce and affiliated companies under a Memorandum of Understanding signed in July 2022. A $10.6 million training facility at Bohle TAFE in Townsville will deliver the training to ensure safe production, handling and use of hydrogen across various applications.

The start of SunHQ construction was officially marked on 1 November 2023.

our impact

The SunHQ hydrogen hub is located within a major industrial precinct at the Sun Metals zinc refinery, with excess green hydrogen available to third-party customers.

Ark Energy may expand the SunHQ electrolyser capacity in time, and is also considering opportunities to build additional hydrogen hubs in Queensland, with production and refuelling stations close to demand clusters.

The Sun Metals Refinery is aiming to be the first refinery in the world to produce green zinc. In addition to the use of green hydrogen, the refinery plans to power its entire operations with 100 per cent renewable electricity by 2040, with an interim target of 80 per cent by 2030.

The CEFC investment will deliver multiple benefits, including:

  • Demonstrating the benefits of hydrogen
  • Accelerating the development of a Queensland-based hydrogen industry
  • Contributing to the achievement of the ambitious green zinc plans of Sun Metals.

In its role as a steel protector, zinc is an essential material for public and private infrastructure development, prolonging the useful life of steel goods and structures and reducing the cost of their maintenance. Zinc is also 100 per cent recyclable.

Ark Energy and Sun Metals are both subsidiaries of Korea Zinc, the world’s largest zinc, lead and silver producer. Sun Metals produces 230,000MT of zinc annually, of which 170,000MT is exported to China, Southeast Asia, the Middle East, Africa and North America.
