Two Australian companies that are developing hydrogen-powered aircraft have successfully registered a family of liquid hydrogen tanks, which will be used for refueling, enabling zero-emission flights across the country.<\/span><\/p>

AMSL Aero<\/strong>\u00a0and Stralis Aircraft<\/strong>\u00a0have registered the tanks, known as \u201cDewar vessels\u201d, in collaboration with BOC Australia<\/strong>. Dewar vessels operate like supersized thermos flasks; they contain a vacuum that insulates super-cold liquid hydrogen. BOC Australia, a Linde company, has led the registration process, laying the foundation for Australia’s first liquid hydrogen flight test programs.<\/span><\/p>

The tanks are crucial for the transportation and storage of liquid hydrogen, and for aircraft refueling. Using the 30 kg capacity Dewars, which are the first of this capacity to arrive in Australia, AMSL Aero and Stralis Aircraft will transport liquid hydrogen from production plants to their aircraft.<\/span><\/p>

Simon Coburn, a Hydrogen Systems Engineer at AMSL Aero<\/strong>, which designs and manufactures the zero-emission aircraft Vertiia<\/strong>\u00a0(pictured above) said: \u201cThere is now a strong global consensus about liquid hydrogen as an aviation fuel. AMSL Aero is delighted to help build another link in a liquid hydrogen supply chain for Australian aviation alongside BOC and Stralis.\u201d<\/span><\/p>

Stuart Johnstone, CTO and Cofounder of Stralis Aircraft<\/strong>, said: \u201cThis is a key step forward for hydrogen-electric aircraft in Australia, enabling liquid hydrogen refueling for ground and flying demonstrator aircraft, and supporting development of a liquid hydrogen supply chain in Australia for future commercial flights.\u201d<\/span><\/p>

Chris Dolman, Business Development Manager, Clean Energy at BOC Region South Pacific<\/strong>, said: \u201cBOC has a long history of working with hydrogen in Australia. It\u2019s always exciting to see innovation and new applications emerge, and we\u2019re pleased to be able to support efforts like these to unlock new opportunities.\u201d<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Stralis Aircraft
<\/strong>Stralis was founded on a singular idea\u2014to\u00a0be the world’s\u00a0leading emission-free aircraft company producing high-performance, low-operating cost, hydrogen-electric propulsion systems and aircraft. The propulsion system incorporates their proprietary high-temperature next-generation fuel cell system that is six times lighter than the current state of the art. Their hydrogen-electric aircraft will travel ten times further than battery-electric alternatives and will be 50% cheaper\u00a0to\u00a0operate than fossil fuel-powered aircraft. Stralis has letters of intent\u00a0to\u00a0buy the aircraft from 11 airlines across Australia, New Zealand, Asia, the USA, and Europe.<\/span>

NASA has been using liquid hydrogen to power spacecraft for decades. Powering aircraft with liquid hydrogen is not a new concept either – the first successful flight took place in 1957. The interest in liquid hydrogen aviation surged during the Oil Crisis in 1973 when there were concerns oil would run out within decades. In the last five years, the aviation sector has turned to liquid hydrogen as a future fuel to reduce emissions, costs and noise.<\/span><\/p>

Many hydrogen-electric aircraft are now in development across the world, both retrofit and clean sheet designs, ranging from two to 100 seats, with ranges up to 4,000 km. Australia is home to two of these clean-tech companies that are leading the way by developing hydrogen-electric aircraft:<\/span> AMSL Aero<\/a><\/u> \u00a0and<\/span> Stralis Aircraft<\/a><\/u> \u00a0and<\/span> .<\/p>

Both companies are part of the Hydrogen Flight Alliance, an organization in Australia dedicated to liquid hydrogen flight. BOC, a Linde company (also a member of the HFA), develops safe, sustainable and innovative solutions for customers in many specialty sectors, heavy industry and medical environments. BOC has been producing, storing, and transporting hydrogen in Australia for more than 80 years.<\/span><\/p>

Why hydrogen?<\/strong><\/span><\/p>

Hydrogen has three times more energy per kilogram than kerosene-based jet fuel and 60 times more energy per kilogram than batteries. Aircraft can be refueled quickly with liquid hydrogen, and it can be produced on site from water and electricity rather than relying on oil shipped across the world. Liquid hydrogen is seriously cold (-253\u00b0 C) and storing it requires specially insulated tanks so that it can be transported from the production facility to the aircraft without boiling away.<\/span><\/p>

There are four hydrogen liquefaction plants in Australia but no vessels to transport the liquid hydrogen from the plant to an aircraft. The standard vessel is known as a Dewar \u2013 essentially a thermos flask \u2013 which has a vacuum to insulate the super cold liquid hydrogen from the outside environment. In order to conduct flight testing, it became imperative to get their hands on a Dewar to enable storage, transport and refueling of fuel. Working together, these companies identified a suitable product in the United States. With BOC leading, they have now registered a family of three Dewars, setting the foundation for their flight test programs and for any other Australian liquid hydrogen users.<\/span><\/p>

Hydrogen is central to the Future Made in Australia<\/em>\u00a0vision and since the release of Australia\u2019s National Hydrogen Strategy in 2019, there have been over 80 announced renewable hydrogen projects and 15 projects that have passed final investment decision. The Government has invested more than $500 million to support development of hydrogen hubs in regional Australia and is developing an internationally consistent Guarantee of Origin scheme with industry, to inform customers about the emissions and other attributes of the hydrogen they buy.<\/span><\/p>

The benefits<\/strong><\/span><\/p>

Australia\u2019s climate goals and international industry commitments require the aviation sector to achieve net zero emissions by 2050. This means that by the mid 2030\u2019s, the sector needs to be actively deploying zero emission technologies and solutions. One solution that can genuinely reduce CO2 and non-CO2 emissions is hydrogen-electric propulsion<\/span> [1]<\/a> . The only emission released from a hydrogen fuel cell is water.<\/span><\/p>

Globally, most domestic aviation services could be serviced by emerging battery electric (short range) and hydrogen-electric (medium range) technologies reducing an estimated<\/span> 50% of global air travel CO2 emissions that come from flights under 2200km<\/a><\/u> . Considering both emissions reduction and aircraft performance in terms of range and power, hydrogen-electric aircraft offer the greatest potential.<\/span><\/p>

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Zero Emissions<\/strong>: No CO2, SOx or NOx. 90% lower lifecycle emissions compared with turbines.<\/span><\/p>

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Useful Range & Payload<\/strong>: Unlike battery electric propulsion, hydrogen electric propulsion delivers commercially viable ranges and payloads.<\/span><\/p>

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Low Fuel Cost<\/strong>: 40-65% lower fuel costs compared with turbine engines.<\/span><\/p>

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Local Aircraft & Fuel Production<\/strong>: Australian made aircraft using Australian green hydrogen.<\/span><\/p>

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Reduced Maintenance Costs<\/strong>: 40-60% reduction in engine maintenance costs vs. turbines.<\/span><\/p><\/td><\/tr><\/tbody><\/table>

Hydrogen-electric propulsion systems are also simpler in comparison with existing aircraft engines. The onboard hydrogen powers a fuel cell that generates electricity to power the electric motor(s), that drives the propellor(s). They have fewer moving parts and operate at lower temperatures than turbine engines, with the potential to reduce engine maintenance costs by between 40-60%. This is similar to the maintenance cost reductions seen with electric cars.<\/span><\/p>

Studies also conclude that hydrogen could be as safe or even safer than kerosene. Handling liquid hydrogen still presents unique challenges and hazards. Specialized equipment and procedures are required to address the risks of leakages, spills and fires [9]. These changes in airport operations are addressed in recent international guidance:<\/span> IATA\/ACI\/Airbus Concept of Operations of Battery and Hydrogen Powered Aircraft at Aerodromes<\/a><\/u> .<\/p>

The Aviation Green Paper states, \u201cAustralia uses around 10 billion liters of jet fuel per year, which amounts to $8.3 billion spend \u2013 90% of which goes offshore\u201d.<\/em><\/span><\/p>

Generating green hydrogen in Australia to fuel emission free aircraft could provide an opportunity to build sovereign resilience of the aviation fuel industry and the aviation sector more broadly. Australia has an abundance of natural resources to make low-emission hydrogen for domestic use and to supply the world, with the largest pipeline of hydrogen projects of any country and an estimated value over $225 billion (DCCEEW). Australia has the ambition to become a renewable energy superpower, and this will be the foundation for commercially viable local hydrogen production.<\/span><\/p>

Australia is well placed and has a unique opportunity to be a leader in the development and production of hydrogen-electric propulsion technologies, aircraft and liquid hydrogen for aviation fuel.<\/span><\/p>

Australia’s transport sector is the third largest source of Australia’s greenhouse gas emissions, amounting to 21% of national emissions in 2023. Since 2005, transport sector greenhouse gas emissions have increased by 19% and are currently projected to be the largest in Australia by 2030.<\/span><\/p>

In 2023, domestic aviation emissions were 9 Mt CO2-e<\/span> [i]<\/a> . Domestic aviation emissions account for 9% of transport emissions. Although emissions from international aviation are not included in Australia\u2019s domestic aviation emissions, international flights departing from Australia in 2019 produced 14 Mt CO\u2082-e.<\/span> [ii]<\/a><\/p>
