The future leaves
signals in time.

According to the article, China is tightening the rules of solar competition through cost accounting, mandatory efficiency standards, tax changes, and capacity controls. It argues the real test is not whether prices rise, but whether excess capacity is removed and the industry can return to sustainable profitability without losing its global cost and technology edge.

This piece asks what comes after lithium in energy storage: whether the future will be defined by one dominant technology or by a diverse mix of technologies designed for different applications. No conclusion is stated in the available context.

ITER published an item titled "Guiding the journal 'Nuclear Fusion' into a new era." The supplied context is sparse and does not describe what the new era involves or any specific actions or results.

On this episode of the This Week in Cleantech podcast, Benton Graham of Grist discusses the Massachusetts Bay Transportation Authority's plans to electrify Boston's Fairmount Line using battery-powered trains.

Jesse Pichel and Lev Seleznov of Roth Capital examine how significant 2026 changes to US trade and energy policy, their enforcement, and potential further changes could reshape the solar market again, covering polysilicon pricing and potential expansion.

University of Groningen researchers calculated green hydrogen production costs of €7.2/kg to €7.3/kg using renewable power purchase agreements and hybrid electricity supply configurations, versus €7.7/kg for wholesale electricity sourcing. The study found long-term revenue guarantees essential to making large-scale hydrogen projects financially viable.

A new study finds that Pakistan's net-metering solar capacity is concentrated in well-served, higher-income utility areas, while much of the country's solar sits unregistered, off-grid and behind the meter in areas with the worst power outages.

Spanish researchers have developed an optical cavity that reduces Boltzmann losses in organic solar cells by restricting photon emission angles. The approach could help push single-junction solar cell efficiencies beyond the Shockley-Queisser limit.

Jackery is entering the RV space with built-in 2 kW solar and 45 kWh storage. The report notes that all-electric trailers already embrace solar and storage, but the work is becoming more custom.

South Africa's government is pursuing 4.6GW of battery storage deployments in its Integrated Resource Plan, placing battery storage and power-to-gas technologies at the heart of the national long-term electricity supply and demand strategy. Further deployment details were not provided in the available information.

Romanian company PhotoVoltaic Windows SRL has found an intriguing application for photovoltaic glass in apartments: heating domestic water. The approach is presented as a case study from Bucharest, with limited further details provided.

Intilion has partnered with CATL for sodium-ion BESS deployments in Europe, following a similar move by Alfen in July. Merus Power is also in the process of integrating with the OEM’s new product.

EUPD Research analyst Ali Arfa told pv magazine that China's dominance of the global battery supply chain is unlikely to change significantly over the next two years. He expects rising inventories to put pressure on residential and C&I storage prices in Europe, while utility-scale battery prices should remain broadly stable.

PowerChina has completed grid connection of a 1 GW hybrid solar project in Qinghai province, China. The facility combines 900 MW of solar PV with a 100 MW concentrated solar power plant featuring eight hours of molten-salt thermal storage and a 20 MW electric heater to store surplus PV electricity.

Finland is currently the Nordic region's most-talked-about battery storage market, with project deals and other development activity from local and international players, according to the report. It rounds up acquisition, construction and optimisation news involving Usva Energia, Nala Renewables, Centrica and Olana Energy.

A recent IEA report said a 35% global electrification target by 2035 is in 'striking distance' thanks to commercial technologies like electric vehicles and battery storage, while electrification of heat-dependent industry sits outside that target. Thermal energy storage can deliver industrial heat and may also play a role in the broader grid system.

Mint Renewables has received planning approval for an 800MWh battery energy storage system (BESS) near Kojonup in Western Australia.
