Netherlands moves forward with plans to link residential PV to heating
The Netherlands will require building owners to adopt renewable energy, connect to local heating networks, or install heat pumps under its implementation of the European Energy Performance of Buildings Directive (EPBD IV).
BBDF 2025: Flexible grid access opens up new paths for battery storage in Germany
Flexible connections, better optimization, and theneed for better cooperation between parties for grid connections were all hot topics in the German-focused second session of the event.
The Hydrogen Stream: Thyssenkrupp Nucera electrolysis sales drop 20%
Thyssenkrupp Nucera reports a more than 20% drop in third-quarter electrolysis sales, with narrowing losses in green hydrogen and falling profits in the Chlor-Alkali segment.
BBDF 2025: Europe’s battery market is still immature
From the floor of the Battery Business & Development Forum 2025, the first session delivered insights around investment strategies in battery energy storage systems across Europe and the UK.
Solar energy to drive Indonesia’s transition away from coal, biofuels
The role of solar PV in Indonesia will extend beyond replacing coal-based electricity generation; it will also include the production of e-fuels for hard-to-abate segments, offering an alternative to land-intensive biofuel production. A recent study explores, through various scenarios, the cost-competitiveness of solar PV-based electrification in supporting Indonesia’s renewable energy transition.
Wireless EV charging based on PV, three-port DC–DC converter
Scientists have developed a wireless charging system for electric vehicles, with a three-port DC–DC converter at its core. They have simulated the system and tested a prototype in their lab and have found it achieved an improved efficiency of 88%.
Pilecom begins work on 106 MW of solar in Australia
Construction of the 106 MW Lancaster Solar Farm in Victoria, Australia, is gathering pace. Western Australian contractor Pilecom is now installing the first of the more than 23,000 piles that will be used in the project.
India achieves 50% clean power capacity five years ahead of target
India reached 484.82 GW of total installed power capacity as of June 30, 2025, with 242.8 GW from non-fossil fuel sources, including 8.8 GW nuclear, 49.4 GW hydro, and 184.6 GW from renewable energy.
What’s behind the aging mechanism of sodium-ion batteries
Researchers in China have used electrochemical impedance spectroscopy to analyze the state of health of sodium-ion batteries. Extracting four features from the measurements, they were able to create a machine learning model for a temperature-resistant state of health estimation method.
German court upholds grid connection charges for battery projects
Germany’s top court has ruled that distribution network operators may require battery storage projects to pay grid connection fees, calling the charges fair as they help prevent overbuilding and shield consumers from excess system costs.
