Allasso Energy Ongoing Geothermal Projects
Karratha South
Located in the high demand Pilbara coastal area, Allasso Energy’s Karratha South permit provides a huge opportunity to deliver reliable green baseload power into the existing heavy power users of the Burrup Peninsula. As many of the areas users move forward with their decarbonisation strategies it presents opportunities for green power producers such as Allasso Energy to meet this demand. Current estimates for the area indicate green power requirements of over 1GW, a significant demand that reliable geothermal baseload can deliver as part of renewable power supply portfolio.
Existing high voltage transmission infrastructure allows for the immediate integration of Allasso Energy’s green baseload power into a network that supplies the iron ore mining districts of Tom Price, Paraburdoo and Newman along with other major Pilbara critical mineral mining provinces and the Port Hedland export hub. This region is currently predominantly gas supported and has a growing demand estimated at over 200MW.
A range of geothermal options are being developed to enable Allasso Energy to scale power generation to deliver the required demand. Adjacent recorded geothermal gradients of Mardie-2 (87.1°C/km) and Mangrove Island (106°C/km) indicate high potential deliverability of the basement at shallow depths. An exploration program focussed on identifying the highest grade deliverable geothermal energy within this play type is underway. Matching this structured approach to a disciplined cost focused execution team allows Allasso Energy to commercialise this resource efficiently, with an expedited timeline to market.
Carnarvon North
Home to a number of planned large scale renewable energy hubs and green hydrogen projects, the Gascoyne region represents an opportunity for Allasso Energy to be well placed in the growth of always on green energy within Western Australia.
Allasso Energy’s Carnarvon North GEP 51 permit straddles the Gascoyne and Ashburton areas in a highly strategic location for renewable energy.
The permit contains a number of offset wells and areas of good seismic coverage that are being used to direct the exploration program, primarily focused on the northern portion of the permit. Depth to basement as determined by seismic surveys indicate accessible geothermal deliverability that would support power generation.
Carnarvon Central
Carnarvon is recognised as a world class green energy location which has attracted significant global investment. Allasso Energy’s permit aims to solidify its presence in the region and provide geothermal energy as an always on renewable power source. With a number of green hydrogen projects under development in the southern Gascoyne region Allasso Energy’s Carnarvon South GEP 50 is well placed to support the sectors green energy baseload demands.
Allasso Energy also recognises the existing agricultural industry that is dominant within the southern Carnarvon region. With proven hot water flows from low cost shallow reservoirs the potential to support this sector with controlled environmental parameters is significant. Direct usage geothermal allows for the optimisation of crops and aquaculture through direct control and optimisation of the growth cycle. The ability to directly heat, cool and control humidity through automated management systems allows complete and accurate environmental control that significantly increases yield and allows for expansion into adjacent marginal areas.
Allasso Energy is also assessing industry options for land based aquaculture within its permit, particularly within areas with direct ocean access lending itself to industries such as fisheries, prawns and asparagopsis (red algae feed supplement).
The expansion of these industries can offer significant direct benefits to Carnarvon.
Onslow Central
The Ashburton region presents a huge growth opportunity for Allasso Energy’s Onslow Central Permit. With high quality geothermal deliverability existing within a few kilometres of existing and planned major demand infrastructure, this permit provides solutions to the area’s decarbonisation requirements. Current estimates for existing green power demand are 500MW with planned major project options driving this up to 1GW within a few years.
Several different play types exist within the permit allowing deliverability risk to be managed. Offset data within the permit supports very high geothermal gradients of consistently >60°C/km nearest to Onslow. Including Topaz –1 (74.2°C/km), Topaz – 2 (63.7°C/km) and Cane River – 2 (76.6°C/km). The permit contains the highest recorded geothermal gradients within Western Australia presenting the lowest cost deliverability potential to industry.
An exploration program focused on identifying the highest grade deliverable geothermal energy closest to existing infrastructure has been prioritised. Matching this structured approach to a disciplined cost focused execution team allows Allasso Energy to commercialise this resource efficiently, with an expedited timeline to market.
