NEWS CeraPhi Drilling Solutions is born 21  November 2023 CeraPhi Energy has launched its Drilling Solutions business, providing the perfect platform to install CeraPhiWell systems. The CeraPhi Drilling Solutions business plans to target deeper well drilling from around 500 metres to 2000 meters. The plan is to access better quality temperatures for next generation ambient loop heat networks. By increasing the recoverable temperature, it reduces the temperature differential. This increases the coefficient of performance of the system, reducing cost and increasing operational margins and system performance.CeraPhi Drilling Solutions Director Paul Fowler said: “This is a great opportunity to provide a scalable solution to maximise the abundance of thermal energy from the heat beneath our feet. The deeper we go, the hotter it gets and drilling to a higher quality heat provides significant benefits for the future of heat networks and the resilience of those systems we install. The interest from the MOD, developers on residential projects, individuals looking to decarbonise private estates, distilleries, football stadiums, schools and leisure centres has been incredible, we already have more than 5 projects in the pipeline which will be delivered within the next 6 months.” CEO of CeraPhi Energy Karl Farrow said: “It’s a natural go-to market strategy for the deployment of our CeraPhiWell solution. It will manage drilling risk and provide an integrated delivery solution taking the heat directly to our customer interconnections and offtakes. It will enable them to connect their heat pumps directly to a higher quality and more efficient source of energy”. CeraPhi has started drilling on projects within the UK. Over the coming months they will invest extensively in their capacity to install fully integrated heat network systems through their Drilling Solutions Business for the USA market within the first quarter of 2024. By the end of 2024, they hope to be providing fully integrated system networks to projects around Massachusetts, Connecticut, and New York State.

ANNOUNCEMENT Loss of our dear friend and colleague Glen Falco   14  November 2023 Glynn Roy Falco (Glen) 08.09.1961 – 20.10.2023 It is with a heavy heart that we have to announce we have sadly lost one of our team. Glen Falco supported CeraPhi Energy since the journey began. He was one of our original shareholders and came on board as a valued member of our team to take up the role of HSEQ manager. Glen brought with him decades of experience in managing situations and procedures safely and he steered us through the vast amounts of paperwork to get us approved to ISO 9001/14001/45001 and to ensure we maintained these standards. He was one of the most vigilant HSEQ managers we’ve ever worked with. However he did this in a way that got everyone on board, he didn’t shout or moan, he encouraged and helped and used his calm approach to steer people into doing the right things. Glen believed with all of his heart in the CeraPhi mission and I am so pleased he managed to get to site to see all of our hard work come to fruition at the proof of concept demo project in Yorkshire. It was soon after this visit when he took ill and began the battle to fight off the cancer that had returned, which was sadly one fight too much for him. Glen was very much a family man and he leaves behind his beloved partner, Ness, his daughter Leah and his parents Ernie and Rose.  Glen had a personality, warmth and gentleness that touched everyone he met. He was a true gentleman. To lose him so suddenly after this last illness was a shock for all of us, but especially his family to whom our hearts go out unconditionally. He will be missed more than we can say, he will stay in our hearts and will always be part of the team.

NEWS Geoconvention 2023 – Nahanni Butte, NWT – Right Sizing Geothermal Development 23 May 2022 CeraPhi’s Andy Wood credited in a technical paper presented in GeoConvention in Calgary. ‘Nahanni Butte is a small community of under 100 people in the south-west corner of Northwest Territories. Presently, the electricity needs of the community are powered by a diesel generator. The heat for the community is provided by oil fired furnaces, oil fired hydronic systems in larger buildings (c.f., Band office and gym), and combustion of wood in individual residences. To increase the community’s energy stability and reduce their carbon emissions, geothermal energy was evaluated for both heat and power generation. Conventional geothermal energy was evaluated for the community, however, the upfront capital cost on a per person for this small community made this solution un-fundable at this point in time. As an alternative, a deep, closed loop, borehole heat exchanger was evaluated for heat production. CeraPhi Energy’s proprietary closed loop CeraPhiWell™ (monobore) system was evaluated. The advantages of this system is it can be deployed in a single, small diameter borehole. Locally available diamond drill rigs running relatively inexpensive HQ drill bit (63.5 mm) sizes can be used. While this solution has better per person economics for the community, it would involve extensive retrofitting of existing heat infrastructure, due to the lower temperatures of the produced fluids than the existing hydronic systems. This limits the applicability of this technology within this community to new residential and commercial buildings, where the heating systems can be designed for the lower temperature fluids circulated by the district heating system. While this area of the NWT has good geothermal potential, the technology implemented needs to consider the community’s needs and future development plans in order to find the best application of renewal energy solutions whether it be geothermal technology, or hybrid systems such as waste heat recovery from existing diesel generation, thermal-solar and/or wind generation coupled with heat storage.’ To view the full poster click here.

NEWS Greenvale Partners with CeraPhi Energy for Ground-breaking Geothermal Feasibility Study 23 May 2023 Greenvale Energy Limited (ASX: GRV, “Greenvale” or “the Company”) is pleased to advise that it has executed a binding Heads of Agreement (HOA) with prominent geothermal development company, CeraPhi Energy, to deliver a feasibility study to unlock the potential of Greenvale’s Longreach Geothermal Project in North Queensland. In addition to outlining the key terms of the feasibility study engagement, the HOA between the two companies gives Greenvale a non-exclusive option to utilise CeraPhi’s CeraPhiWellTM proprietary patents for its ground-breaking closed-loop geothermal technology.   Greenvale’s technical team sees the CeraPhiWellTM proprietary patents as integral to unlocking the immense geothermal potential of its geothermal exploration permit application areas, specifically those in Longreach and the exciting Millungera Basin region. CeraPhiWell™’s proprietary patents pertain to the unique design and installation of a down-hole heat exchanger system that innovatively employs existing technologies. This system offers remarkable versatility, enabling the recovery of commercially viable heat energy from the sub-surface in a wide range of locations. Furthermore, the CeraPhiWell™ serves as a dependable contingency for wells that do not meet production expectations. Commenting about the engagement of CeraPhi Energy, Greenvale CEO, Mr Mark Turner, said: “We are very excited to be working with the CeraPhi Energy team. Not only will their skills and experience be of great benefit in advancing Greenvale’s geothermal project areas, but the option to utilise their proprietary patents will undoubtedly prove invaluable as our geothermal strategy advances.” Karl Farrow, Founder and Chief Executive Officer of CeraPhi Energy, said: “Mining companies face significant challenges in decarbonisation due to the remote locations that many of these activities are carried out in. The ability to produce energy from closed loop geothermal virtually anywhere, enables us to place the energy where it is needed reducing the requirement of significant transmission and distribution systems which are not always possible and extremely costly to install. The opportunity to work with Greenvale Energy on this project demonstrates the versatility of our closed loop geothermal approach and its ability to become an anywhere solution for everyone.” Greenvale is taking bold steps to explore new sustainable energy technologies and opportunities, in parallel with the advancement of its flagship Alpha Torbanite Project (QLD). The Company’s commitment to finding an appropriate renewable energy source, is integral to unlocking the immense potential of Alpha.   In line with this commitment, Greenvale has chosen Longreach as the pilot area for its geothermal energy strategy and will partner with CeraPhi Energy to assess the effectiveness of its proprietary patents for the CeraPhiWellTM down-hole heat exchanger system. Greenvale is continuing to make significant inroads with its renewable energy strategy, with EPG 2029 close to being awarded and plans to build Australia’s first geothermal power station in Longreach using CeraPhi Energy’s closed-loop technology. This technology will enable Greenvale to produce 24/7 baseload renewable energy with no groundwater usage, making it an environmentally friendly and sustainable option. Moreover, the Queensland State Government’s recent takeover of the CopperString Project is a positive development for Greenvale. The Project runs through Greenvale’s EPG applications in the Millungera Basin, putting the Company in a favourable position to pursue geothermal opportunities in the area. The successful implementation of the Longreach Project is expected to pave the way for a larger-scale geothermal energy plant in the Millungera Basin, in line with the advancement of the CopperString Transmission Project. Greenvale’s innovative approach and the adoption of new technologies position it as a significant challenger in the sustainable energy industry, with the potential to drive real change. About CeraPhi Energy CeraPhi Energy was established with a clear mission to harness the power of geothermal energy and use it to create a meaningful impact in the global effort to reduce carbon emissions and combat climate change. The company boasts a unique blend of innovation, technology development, and has extensive experience in delivering successful energy infrastructure projects. This expertise is brought to bear on the development, delivery, and operation of projects that maximise returns and benefits for all stakeholders involved. Through its commitment to sustainability and cutting-edge technology, CeraPhi Energy is a key player in the drive to create a more sustainable and eco-friendly energy landscape. About CeraPhiWell™ The CeraPhiWell™ technology represents a breakthrough in closed-loop geothermal well systems, utilising a specially selected fluid circulated down a closed-loop well via proprietary systems that act as a down-hole heat exchanger. Using proven oil and gas techniques and equipment to drill wells up to 5 kilometres deep, higher temperatures can be accessed and brought to the surface. The required heat output and the ground temperature gradient at the site determine the depth of the well. Once installed and operational, the CeraPhiWell™ system requires minimal maintenance and no further interventions. Notably, the system is fully sealed, with no interaction with below-ground aquifers or permeable formations – and poses no potential hazard for unwanted pollution. Unlike conventional geothermal projects, there is no need for fracking techniques, which significantly reduces the risk of seismic events. These features of the CeraPhiWell™ technology greatly reduce the risk profile for geothermal projects and increase confidence in their successful development and operation. Geothermal Closed Loop Technology Fluid is circulated through the system (blue) down to the heat exchanger (1) where temperatures at the bottom of the well results in the conduction of thermal energy (red), which is returned to the surface heat exchanger (2). The thermal energy, in a controlled combination of pressure and temperature, is then routed through the surface heat exchanger to another medium within the Organic Rankine Cycle (ORC) plant. This energy expands into the ORC turbine (3), internally turning the generator to produce electricity (4). The hot fluid is then directed to the coolers (5), condensing into a cooler state and returning to the surface heat exchanger (2), where the well circulation reheats it. Power is sent to the substation (6) for transmission to the end user. Advantages of Geothermal Closed-Loop Technology Geothermal closed-loop technology offers several significant environmental advantages over
