Energy Digest

Battery technology is expected to play a crucial role in the future energy system, with a total demand of over 350 TWh by 2050. This is driven by a need for large capacities of stationary and mobile battery storage, driven in part by the need for high electrification and renewable energy systems. The development of alternative battery technologies, such as Sodium-ion batteries, is seen as a key solution to meet this demand.

European power purchase agreement (PPA) prices rose 5% in September, with countries like Great Britain, Italy, and Poland experiencing the largest monthly increases, while the Iberian Peninsula saw prices fall. PPA contracting activity recovered in September, with 25 agreements totaling 1.2 GW of announced capacity, led by corporate buyers accounting for 92% of the capacity. Onshore wind slightly exceeded solar PV in contracted capacity, with 281 MW and 276 MW, respectively.

Several major companies in the downstream battery storage market, including Neoen, BW ESS, and MN8, are joining an initiative to standardize BESS procurement through the formation of a new Energy Storage Contract Alliance. The alliance aims to simplify the process of buying energy storage systems, potentially reducing costs and increasing efficiency.

Wärtsilä's energy storage joint venture, Valo, is in discussions with US suppliers about increasing domestic content manufacturing, aiming to strengthen its supply chain in the US market.

Italy's solar capacity is expected to reach between 114 GW and 137 GW by 2040, with solar power generation increasing from 44 TWh in 2025 to 156 TWh and 185 TWh by 2030 and 2040, respectively. The country's renewable electricity generation is projected to account for over 52% of total electricity production by 2030, with a combined solar and wind capacity expected to reach approximately 103 GW by 2030. Italy aims to cover 63% of its electricity demand with renewables by 2030.

Qcells is planning to build a giant factory to produce next-generation tandem solar panels, which use layers of materials to increase efficiency. This new technology aims to convert sunlight to electricity with much higher efficiency than traditional silicon cells. The company is a prominent player in the US solar manufacturing industry.

Samsung C&T has referred an 800MWh battery energy storage system (BESS) in Victoria's Gippsland region to the Australian federal government under the EPBC Act. The BESS is located in Victoria's Gippsland region.

Battery energy storage systems in New South Wales earned an estimated AU$5.63 million in two hours, with wholesale electricity prices reaching a record AU$23,107/MWh on October 12. This extreme price event highlights the value of BESS in stabilizing the energy market and profiting from price volatility. The event underscores the significant economic potential of BESS in Australia's energy market.

Pebble is upgrading its 2027 Flow model to incorporate a microgrid system that can power both adventures and homes. The updated model features advanced lithium batteries, rooftop solar, and public EV chargers, transforming it into a self-sufficient living space. The upgrade aims to provide a reliable source of energy for outdoor enthusiasts and those looking for a sustainable living solution.

Fervo Energy has launched the first utility-scale enhanced geothermal plant, Cape Station, in Utah, producing 33 megawatts of carbon-free electricity. The project, valued at $2 billion, uses drilling techniques to create geothermal resources in hot, dry rocks, generating steam to produce electricity. The facility will eventually supply 500 MW of electricity to the grid.
