4. Hydrogen Developments in Australia & around the world
Tokyo has the Hydrogen Olympics next year and will be showcasing many new applications
Power2Gas projects are world wide but Australia can lead due to abundant solar resources
CSIRO have developed a membrane to extract hydrogen from ammonia
Electrolysers can now be more than 80% efficient.
Fuel Cells are now viable and car manufacturers are releasing production models.
Hydrogen trucks and buses are likely to be in service by end 2020
ALP are proposing to spend $1B on increasing hydrogen for local consumption and export

6. Geo-locate Electrolyser sites using Enzen 3D mapping
Locate where points of electrical constraint intersect with gas lines and vehicle filling locations.
Modular design of smallest energy station to suit 500kW transformer which can be stacked up to 5MW.
Power2Gas as minimum provision for storage with options for:
H2 filling station
EV Fast charge
Batteries
Fuel Cell
Generator

7. Hydrogen – Use case for local hydrogen
There is huge untapped potential in Australia for Power2gas by converting surplus solar PV and wind energy to hydrogen using electrolysers.
By using our existing gas network infrastructure to store hydrogen we are providing a no cost base case for large energy storage.
By AGIG and Govt. investing in this storage solution, then half the cost of hydrogen for transport use is covered.
The economics of Power2gas can improve if combined with grid management revenues available from stabilising the grid.
Enzen has identified customer use cases for increasing the distribution volume with the biggest being residential VPPs (Virtual Power Plants) who need cheap local storage when they don’t want diesel gensets and batteries are too expensive.
Enzen would like to partner with organisations to enhance the commercial, residential, council, and transport use of hydrogen.

8. Mines currently using gas are potential sites for Hydrogen

9. McArthur River Operations
Natural Gas is Supporting Glencore Xstrata’s McArthur River mine expansion.
Glencore has operated existing the 24MW gas power station since 1995
The expansion programme has doubled the mine’s capacity to 68MW of power
The new 53MW Wärtsilä engine can take up to 30% hydrogen from an 30MW electrolyser from a 50MW solar farm

10. Yulara CNG Transport Project for Territory Generation
Add electrolyser for blending up to 20% into CNG supply to the gas generators
1MW electrolyser supplied by excess solar from the 1.8MW in the area (red)

12. AGIG has already invested in local hydrogen in SA
The $11.4 million AGIG hydrogen project at Tonsley will trial Power2Gas through Enwave which is part of the Brookfield services group using a 1.25MW Siemens electrolyser
In Port Lincoln, AGIG are investing $117m in a Hydrogen Utility (H2U)plant which includes a 30 MW water electrolysis plant, as well as a facility for ammonia production.
It will include a 10MW hydrogen-fired gas turbine, fuelled by local wind and solar power, and a 5MW hydrogen fuel cell.

13. Hydrogen use cases across value chain
Challenge
Commercial
Residential
Council Government
Transport
Mining plants can use hydrogen with CNG or LNG
Property developers using grid management electrolysers for managing solar export
Council depot H2 refuelling stations
CNG bus can use up to
15% hydrogen blend from electrolyser and local solar array.
Carbon Neutral city buildings
Other manufacturing plants in Top End
Local electrolysers for balancing street transformers in VPPs
H2 buses are available which can be used for peak electricity generation VPP back up
NT Govt. trials of Power2Gas and H2
Ammonia Chilling Plants for food and export industries
Local H2 filling stations for fuel cell vehicles added to energy station when cars available
Hydrogen school buses more feasibility than EV buses for country areas like Darwin
NT mining use
Power2 Gas
Upgrade of landfill and other waste biogases
Increased % of hydrogen for cooking appliances - trials with changing burner jets

14. Local Hydrogen Power2Gas Strategy
Gas Main
Grid balancing revenues from the electrolysers make hydrogen viable for Power2Gas

15. 60kW Electrolyser Design for local manufacture
This design is capable of load balancing a local street transformer.
Designed to be paralleled up to 5MW.
Energy station small container format can be packaged with H2 filling and other revenue generating options depending upon site requirements.
Future options like batteries and fuel cells are accommodated for in the energy station design.
Joint venture or partnership with Govt. funding to achieve <$1/watt production cost

16. Local Hydrogen Bus Strategy
Hydrogen buses can provide backup power at peak demand time.
Hydrogen is most suited to school buses which can support local VPPs in times of peak demand.
May be applicable to unstable networks like Yulara and Alice Springs

17. Local CNG Bus Strategy
CNG buses can support a 15% hydrogen blend through the existing CNG filling stations.

18. Darwin Virtual Gas Pipeline Project
Key Capacity Issues:
A capacity of 400 tons per day of LNG production is proposed, to be distributed to the wider expanses of the region via road and rail, and in specially constructed ISO Tanks.
These ISO tanks can be delivered in customer specified quantities and frequencies, and in tank sizes of either 22,000 litres or 44,000 litre capacity. In a process known as “virtual gas pipeline”.
Economic Benefits:
$250 million expenditure on the LNG production and distribution facility will generate:
 Tendering and supply opportunities to the region;
 375 construction positions;
 65 Administrative and ongoing operational positions;
 Forecast to create approximately 1,000 secondary employment positions.
LNG use as a diesel fuel replacement will:
 Reduce the operating fuel costs of participating industries by $51 million per annum, which represents fuel cost savings of approximately 25% over their existing fuel costs,
 Replace the daily consumption of 560,000 litres of diesel fuel;
 Reduce the need to import Diesel fuel by up to $160 million per annum
 Assist to reduce regional community living costs by reducing the transport costs component.
Environmental Benefits:
LNG use as a replacement fuel for Diesel will reduce greenhouse gas emissions by 25%
 Heavy vehicles in the road transport sector, (buses and Trucks)
 Rail Sector (Passenger and Freight)
 Electricity Generation ( Mining sector, Remote Communities)
 Mining Sector Machinery and Heavy Haulage Equipment
 Combined with up to 20% locally produced Hydrogen from on site electrolysis to reduce costs

19. Virtual Pipeline 9
• AAB series road trailer combination considered the best option
– Greter stability than traditional AAA road trains
– Greater pay load (~1.4 TJ)
• CNG tanks are 10 ft modular packages with LNG tanks similar to traditional bulk tanker haulage
