Hydrogen will play a key role in addressing the challenges of climate change. Most developed countries around the world have set targets for net carbon neutrality by 2050 and are actively developing strategies and policies to achieve these goals. To date, the Australian government has resisted calls to set a target date for achieving carbon neutrality, however, it recently announced a funding injection to accelerate development of the Australian hydrogen industry.
This is a step in the right direction and includes $275.5 million to develop regional hydrogen hubs including money to implement a clean hydrogen certification scheme, and $263.7 million to develop carbon capture and storage technology. The aim is to drive down the cost of hydrogen production to less than $2/kg so it can compete against fossil fuels
International demand for renewable hydrogen is growing rapidly as countries commit to reducing greenhouse gas emissions, and Australia is well placed to produce renewable hydrogen for domestic use and to become a major exporter to countries such as Japan and South Korea. International markets want renewable hydrogen to replace natural gas and this represents a massive new market opportunity for Australia. It has been estimated that the renewable hydrogen sector could potentially be worth up to $26 billion per year and generate nearly 17,000 new jobs by 2050.
Prime Minister Scott Morrison said this additional $539.2 million investment in the 2021-22 budget will create 2500 jobs, however, some critics have questioned the funding of carbon capture and storage technology.
The Prime Minister also announced the Australian Government will invest a further $565.8 million into establishing low emissions technology partnerships and initiatives with key trading and strategic partners. Dr Alan Finkel has been appointed as Australia’s Special Adviser on Low Emissions Technology and will play a key role in brokering new international partnerships.
The Hydrogen Energy Supply Chain (HESC) Pilot Project is an example of what can be achieved through international partnerships. The HESC Pilot is developing a world-first hydrogen supply chain to overseas markets by creating hydrogen from gasification of Victoria’s Latrobe Valley coal, transporting hydrogen to the Port of Hastings on Victoria’s Westernport Bay by road in high pressure tube trailers for liquefaction. The facility at the Port of Hastings will liquefy hydrogen gas by cooling it to -253oC and reducing it to 1/800th its volume and storing it in a multi-layer vacuum insulated cryogenic containers. Approximately once every three months the stored hydrogen will be loaded onto a the world’s first purpose-built liquefied hydrogen carrier, the Suiso Frontier for shipment to Japan.
The HESC Pilot is being delivered by a consortium of industry partners from Japan and Australia including Kawasaki Heavy Industries, J-Power, Iwatani Corporation, Marubeni Corporation, AGL and Sumitomo Corporation, supported by the Victorian, Australian and Japanese Governments. The next major HESC Pilot development will be the first shipment of hydrogen between Australia and Japan later this year aboard the Suiso Frontier. A commercial-scale HESC project could produce 225,000 tonnes of clean hydrogen annually with carbon capture and storage.
The Victorian and Commonwealth Governments’ CarbonNet Project is developing in parallel with HESC and is essential for the hydrogen pilot’s commercialisation. If both projects are commercialised, CO2 captured during hydrogen production would transported and stored by CarbonNet using carbon capture and storage (CCS) technology. Rather than entering the atmosphere, CO2 emissions will be stored in rocks 1.5 km beneath Bass Strait, similar to the way oil and gas was been trapped naturally.
These along with many other initiatives herald a very exciting future for Australia’s hydrogen industry and will help to deliver the strategic infrastructure required to support the production, distribution and utilisation of hydrogen.
Since the launch of the AGA Listed Gas Fitter Scheme on the 1st September 2020, we have received positive support from our industry. We would like to thank the licensed gas fitters nationwide who have signed up and are now members of AGA.
The AGA Listed Gas Fitter Scheme runs national safety campaigns to promote public awareness that only licensed gas fitters should be engaged to install gas appliances, and the need for regular gas appliance servicing by licensed gas fitters. The Scheme is assisting with consumer awareness of the need for gas appliances to be serviced regularly.
Gas fitters who sign up become members of AGA, are licensed to use the AGA logo and are listed on the AGA Gas Fitter Directory.
The recent publication of AS/NZS 5263.1.3: 2021 incorporates significant changes in relation to Energy labelling with the objective to improve transparency and reproducibility and also to consider installation conditions i.e. room ventilation.
The previous version of the Standard did not consider the heat loss due to room ventilation requirements and this has resulted in additional factors within the energy label calculations. These factors now include:
* Daily heat load – The sum of the daily ambient heat load plus the daily ventilation load
* Ambient heat load – Heat load due to temperature difference between inside (deemed to be 21oC) and outside (deemed to be 7oC)
Maximum ambient heat load – 0.15 MJ/h/m3
Average ambient heat load – 0.075 MJ/h/m3
* Ventilation load – This varies depending on the heater type and is not applicable to room sealed heaters due to all air required for combustion taken from outside.
* Calculated room size – Based on the heater output and the maximum ambient heat load.
* Heater output rate at high / turndown / standby – This factor includes 50% of the room fan electrical energy consumption (recognizing the poor efficiency in conversion of electrical consumption to heat).
* Heater on time – The time that the heater is required to be on to deliver sufficient heat to satisfy the calculated daily heat load.
* Daily energy input – Calculated from measured gas rate and electrical energy consumption at high, turndown, and standby and calculated on times.
* Task efficiency – Calculated from the daily ambient heat load divided by the daily energy input.
* Red band angle and stars -Calculated from the task efficiency. The calculation achieves similar star ratings as for current flued and room sealed heater, but lower star rating for flueless heaters due to the added ventilation load.
* Annual energy consumption – Calculated from the daily energy input for 100 days.
* Maximum heater output – Calculated from the measured high gas rate, fan electrical energy consumption and thermal efficiency.
All gas space heating appliances will require re-assessments to account for these changes and for more information, Appendix CC / DD of the new Standard also includes background and derivation information for reference purposes.
AS/NZS 5601.1 (Gas installations – Part 1: General installations ) is open for public comment until the 10/06/2021
