Quaise, Inc was founded in 2018 to develop a drilling system for converting existing power stations to use superdeep . The system would repurpose existing technology to drill 20 kilometers beneath the surface, where temperatures exceed 400°C. No fracking would be required, avoiding the potential for in other geothermal systems. Drilling using this technique is hoped to be fast, with boreholes aime. [pdf]

United Arab Emirates-based clean energy company Masdar has completed the acquisition of Terna Energy in a €3.2bn ($3.3bn) deal.. United Arab Emirates-based clean energy company Masdar has completed the acquisition of Terna Energy in a €3.2bn ($3.3bn) deal.. Abu Dhabi-based Masdar has taken a majority stake in Greek renewable energy company Terna Energy, with plans to launch an all-cash mandatory tender offer to acquire the outstanding shares. [pdf]
With a strong portfolio of projects in Greece and Europe, TERNA ENERGY is the largest investor in the renewables energy sector in Greece. The proposed acquisition is expected to play an important role in growing Masdar’s portfolio in Europe as it targets 100GW global capacity by 2030.
TERNA ENERGY will play an important role in enhancing Masdar's portfolio across Europeas it targets 100GW global capacity by 2030 in support of the energy transition. Mohamed Jameel Al Ramahi, Chief Executive Officer of Masdar, commented: "Masdar is proud to become the majority shareholder of TERNA ENERGY, bringing together two energy champions.
Our agreement with Masdar is a recognition of the great value of TERNA ENERGY and the result of the hard work of hundreds of people for more than 25 years. At the same time, it marks the beginning of a new era of even greater growth for GEK TERNA Group. It is also a strong vote of confidence for Greece and its prospects.
Established in 1997, TERNA ENERGY is a leading European clean energy platform, with a track record of more than 25 years of delivering innovative and sustainable projects. The company specializes in financing, developing, constructing and operating renewable energy facilities, focused on wind, solar, hydroelectric and pumped storage projects.
Demonstrating continuity in leadership, TERNA ENERGY’s Executive Chairman, Georgios Peristeris, and Chief Executive Officer, Emmanuel Maragoudakis, will continue in their current roles following completion of the transaction and support Masdar in leading the company in its next phase of growth.
"Masdar's acquisition strategy has focused on acquiring not just assets, but investing in exceptional teams.

With a power output of 30 megawatts, China’s Dinglun flywheel energy storage facility is now the biggest power station of its kind.. With a power output of 30 megawatts, China’s Dinglun flywheel energy storage facility is now the biggest power station of its kind.. The Dinglun Flywheel Energy Storage Power Station, with a capacity of 30 MW, is now the world’s largest flywheel energy storage project which is operational, surpassing previous records set by simi. . The world's largest compressed air energy storage station, the second phase of the Jintan Salt Cavern Compressed Air Energy Storage Project, officially broke ground on December 18, 2024 in Changzho. . In October 2021, Huawei and SEPCOIII, a subsidiary of PowerChina, were awarded the Saudi Red Sea New City Energy Storage project, the world’s largest energy storage project signed in 2022.. A compressed air energy storage (CAES) project in Hubei, China, has come online, with 300MW/1,500MWh of capacity. [pdf]
From ESS News China has connected to the grid its first large-scale standalone flywheel energy storage project in Shanxi Province’s city of Changzhi. The Dinglun Flywheel Energy Storage Power Station broke ground in July last year.
Developing energy storage is an important step in China's transition from fossil fuels to renewable energy, while mitigating the effect of new energy's randomness, volatility and intermittence on the grid and managing power supply and demand, he said.
According to Shu Yinbiao, an academician at the Chinese Academy of Engineering, the utilization rate of new energy storage in China is not high, with the average utilization rate indexes for grid-side, user-side, and mandatory allocation of new energy storage projects reaching 38 percent, 65 percent and 17 percent, respectively.
The skyrocketing demand for energy storage solutions, driven by the need to integrate intermittent renewable energy sources such as wind and solar into the power grid effectively, has led to a flurry of investments in energy storage projects across the country, the NEA said.
New energy storage, or energy storage using new technologies such as lithium-ion batteries, liquid flow batteries, compressed air and mechanical energy, is an important foundation for building a new power system in China, enjoying the advantages of quick response, flexible configuration and short construction periods.
It is the largest grid-connected CAES project of its size in the world, engineering firm China Energy Engineering Corporation claimed in its announcement of the project (or specifically, the first in the world of that scale). The project is owned by China Energy Construction Digital Group and State Grid Hubei Integrated Energy Services Co.
