The future is geothermal
With community at heart , Star Energy Group fosters social and environmental responsibility
Historically , Star Energy Group ( Star Energy ) primarily focused on oil and gas extraction . But as time went on , the British energy company strategically shifted towards leveraging its highly complementary skill set to develop a significant geothermal business , thereby facilitating the transition to a renewable future . For more than three decades , Star Energy has been a pivotal player in onshore energy production in Britain , safely exploring , developing , and producing onshore oil and gas at its sites . The organization ’ s management and technical teams boast many years of experience in onshore energy production , with most of them living and working in the communities in which Star Energy operates .
While there remains an undeniable need for oil and gas in a net-zero environment , Star Energy has begun to diversify into renewable energy with the acquisition of GT Energy , a geothermal energy developer , in 2020 . This move marked the company ’ s expansion into the UK renewable energy sector , where there is a clear opportunity to decarbonize large-scale heat . Geothermal resources , characterized by hot water reservoirs at varying temperatures and depths beneath the Earth ’ s surface , offer a sustainable energy solution for use in heating and cooling .
Predictable and stable
A pair of wells , known as a doublet , from a few feet to several miles deep into these underground reservoirs , are filled with brine . One of the two wells is used to extract the geothermal resources by pumping the hot water to the surface . From there , the heat is transferred to the surface system through a heat exchanger . The brine is then returned to the reservoir through the second well . After being heated by passing through the heat exchanger , the water in the surface system can be utilized for district heating networks or connected directly to other customer networks . By embracing geothermal energy , Star Energy aims to decarbonize heating , reduce its reliance on imports , and help to safeguard Britain ’ s energy security . Indeed , as a non-extractive renewable energy source , geothermal heat can play a key role in cutting the UK ’ s carbon emissions . Moreover , unlike other forms of renewable energy like wind and solar , geothermal heat is constant , switchable , and unaffected by the weather , ensuring a
