Overview
The Australian Renewable Energy Agency (ARENA) has awarded a $15 million grant to clean technology company Hadean Energy to fund half the $30 million capital cost of a pilot green hydrogen production facility at the Port of Hastings in Victoria. RenewEconomy reported the funding on 5 November 2026. The pilot will use tubular solid oxide electrolysis (SOE) technology developed by CSIRO. It will be built at BOC’s industrial gas facility at Hastings, next to BlueScope Steel’s Western Port operations. RFC Ambrian Funds Management, Amarna Energy and private investors are funding the remainder of the project.
Electricity cost is the main constraint on green hydrogen economics, and that is why this project matters. Hadean claims its system needs up to 30% less electricity per kilogram of hydrogen than conventional low-temperature electrolysers. It achieves this by using high-temperature steam and industrial waste heat to supply part of the energy needed to split water. The project also has a defined customer. The hydrogen will go into steel annealing at the neighbouring BlueScope operations, which makes it a test of direct industrial off-take in a hard-to-abate sector.
The project is also relevant to Australian environmental professionals, developers, lawyers and councils for a practical reason. It shows hydrogen production moving into established port and heavy industrial precincts. These sites bring legacy land condition, water supply, dangerous goods and sensitive receiving environment issues into the approvals pathway. Western Port is a Ramsar-listed wetland, and the source article identifies the Port of Hastings as the site of a proposed offshore wind hub. Both points add weight to environmental assessment of new industrial plant in the precinct.
Key details
The main technical difference in Hadean’s system is cell geometry. Conventional high-temperature electrolysers use planar, flat-plate ceramic stacks that are sealed along their long edges. Thermal cycling puts stress on those seals, which leads to cracking, performance degradation and gas leaks. Hadean’s tubular ceramic cells are sealed only at the tube ends. This design reduces the seal length exposed to thermal stress and targets one of the main durability problems that has held back solid oxide electrolysis at commercial scale.
The energy saving comes from the thermodynamics of high-temperature operation. Alkaline and proton exchange membrane (PEM) electrolysers typically use about 50 to 55 kWh of electricity per kilogram of hydrogen at system level. In a solid oxide system running on steam, heat provides part of the energy needed for the water-splitting reaction, so less electricity is required. Hadean’s claimed reduction of up to 30% would bring electricity demand to roughly 35 to 39 kWh/kg H2. This is our calculation from the published percentage, not a figure stated by the company. The pilot plant is rated at 200 to 300 kW and will produce up to 7 kg of hydrogen per hour. At that output, the calculated electrical load is about 245 to 270 kW, which sits within the stated plant rating. Operating data from the pilot will show whether the claimed efficiency holds outside the laboratory.
The off-take arrangement is the second notable feature. According to RenewEconomy, 7 kg/h is enough to supply about 85% of the hydrogen used in the high-temperature annealing process at BlueScope’s Western Port operations. Supplying an adjacent user removes the need for long-distance transport or large-scale storage, which are major cost and safety items in many hydrogen proposals. If the plant ran continuously at full output, it would produce a theoretical maximum of 168 kg of hydrogen per day. This figure shows that the facility is a pilot plant sized to a single process stream, not a merchant export project.
Water is a design input that receives less attention than electricity. On a stoichiometric basis, electrolysis consumes about 9 L of water per kilogram of hydrogen. At 7 kg/h, that is about 63 L/h before allowing for purification losses. Electrolysers need high-purity feed water, so any treatment system will also generate a reject stream. The volumes are small at pilot scale. They become material when a project is scaled up, particularly where the feed water source is constrained or the discharge pathway runs toward sensitive coastal waters.
Australian context
The project connects directly to the reformed Safeguard Mechanism under the National Greenhouse and Energy Reporting Act 2007 (Cth) and the National Greenhouse and Energy Reporting (Safeguard Mechanism) Rule 2015. Facilities emitting more than 100,000 t CO2-e of Scope 1 emissions a year are covered. Their baselines decline by 4.9% each year to 2030. Facilities that exceed their baselines must buy and surrender Australian Carbon Credit Units (ACCUs) or Safeguard Mechanism Credits (SMCs). Replacing fossil-derived hydrogen with electrolytic hydrogen in a thermal process such as annealing is physical abatement and can be verified. Whose emissions inventory benefits depends on ownership. If the user produces the hydrogen, the reduction appears in its Scope 1 emissions. If the user buys hydrogen from a third party, the benefit sits within its Scope 3 accounting. Supply contracts should be clear on this point before any emissions claims are made.
In Victoria, the Environment Protection Act 2017 sets the main state-level obligations. The General Environmental Duty under section 25 applies to anyone engaging in an activity that may pose risks of harm to human health or the environment from pollution or waste. It applies whether or not the activity needs a permission under the Environment Protection Regulations 2021. On port and industrial land, the duty to manage contaminated land under section 39 also applies to the person in management or control of the site. Hydrogen storage and handling is regulated separately under the Dangerous Goods Act 1985 (Vic) and the Dangerous Goods (Storage and Handling) Regulations 2022, which WorkSafe Victoria administers. Hydrogen is a Class 2.1 flammable gas, and the regulations set requirements for hazard identification, risk control, signage and emergency planning that increase with the quantities held on site.
New plant in the precinct will also need to be assessed under the Planning and Environment Act 1987 (Vic) and the relevant planning scheme. Because Western Port is a Ramsar site, a proposal with the potential to significantly affect its ecological character may also need referral under the Environment Protection and Biodiversity Conservation Act 1999 (Cth), as wetlands of international importance are a matter of national environmental significance. At pilot scale these triggers are less likely to be decisive. They will carry more weight if the technology moves to larger installations at Hastings or similar coastal industrial sites, where site history, wastewater discharge, dangerous goods storage and proximity to protected wetlands will be assessed alongside the energy and emissions case.
