New space-efficient battery storage from Saft
Saft, a subsidiary of TotalEnergies, has developed a new high-energy density storage system (ESS) optimised for time-shifting applications, a key enabler for the large scale integration of low- carbon renewable energy on power grids.
Designated Modular Intensium Shift (I-Shift) the 3 MWh containers are scalable building blocks and can be installed in combination with power conversion equipment with a 50% smaller system footprint, while reducing 50% of site- related activities, allowing a faster deployment of utility-scale storage plants.
The new unit is said to provide for easy sea and road transportation, standardisation, and plug-and-play installation to speed up project delivery. For instance, says Saft, four groups of twin line-ups with 48 I-Shift containers can provide a reliable 32MW/128 MWh four- hour energy storage system with lower land requirements and civil works’ needs. Hervé Amossé, Saft’s executive vice president for energy storage commented: “I-Shift’s
‘Tomorrow ready’ digital MV circuit breaker
ABB has evolved its VD4 medium voltage circuit breaker design to be ‘safer, smarter and more sustainable, with advanced digital features’. It is claimed to help reduce the risk of power outages by 30 % and increases operations and maintenance efficiencies by as much as 60 %. The new ‘VD4 evo’ design is said to incorporate Industry 4.0 level sensor enhancements for all thermal, mechanical and electrical parameters along with an advanced Central Monitoring Unit for 24/7, real-time analytics. Key information is delivered via a simple, intuitive dashboard, enabling ‘unparalleled’ visibility of equipment data, status and condition from anywhere in the world. This is completed with diagnostics reports
and alarm notifications based on ABB’s in house experience base.
The result is said to be a series of significant operational and financial benefits for users, such as panel builders and original equipment manufacturers (OEMs), thanks to the ability to detect and address issues ahead of time. Alongside this, it becomes easier to predict wear and tear and increase overall lifespan and output. Sustainability is also said to be enhanced by the unit’s ultra-compact design and energy efficient operation, which is fully Environmental Product Declaration (EPD) certified. It is 15 % smaller compared to traditional MV breakers and also plays its part in helping to save CO2
emissions over the 30 year lifetime of a 14-panel unit – up to 150 tons.
The new CB is now available, is fully compatible with existing VD4 breakers, and has a simple, ‘plug and play’ design. It is available as a standalone solution, but can also be used with the ABB Ability Asset Manager platform.
‘Climbing crane’ to be developed
Vattenfall has teamed up with heavy lift specialist Mammoet to develop a new design of wind farm crane that it believes will reduce the carbon footprint of its operations.
The ‘climbing crane’ concept uses the turbine tower instead of the ground for support as it adds more sections in stages, with no limit on how high it can go. Although it is still on the drawing board, progress to date has been encouraging and a Vattenfall team from its business unit Onshore Wind is now working with Mammoet to take the development of the concept forward with a realistic hope that the new technology could be seen on sites within the next few years. For programme manager Jelmer Boukes and his team at Vattenfall, it would represent ‘one of the biggest step-changes seen in wind farm construction for years, offering multiple benefits

www.modernpowersystems.com in terms of CO2 reduction, minimised impact on
local communities and cost benefits.’ “The climbing crane would be much smaller and easier to get to site, as well as to move to another location when it has completed a turbine,” Boukes says. Also, the climbing crane would be able to reach greater heights and operate in locations with up to 80 % more wind, unlocking new complex and remote wind farm sites.
The reduction in transport activity around the building site due to the new crane, should reduce the carbon footprint of construction and impact on the local community. There also expected benefits in the operation of the crane itself. Owing to its much smaller engine and capacity requirement, the crane could be powered by electricity instead of fossil fuels.
innovative design, covered by eight new patents, includes improvements on thermal efficiency and ruggedness, with 30% more storage capacity.” Available from mid-2023, Intensium Shift (I-Shift) is based on lithium iron phosphate (LFP) technology. It is said to be suited to energy time- shifting, peaking and capacity support applications on transmission and distribution grids. Customers can use these individual 20-foot 3.0 MWh containers to handle the output of multi-megawatt sites for between two and eight hours, either co- located on renewable farms, or as standalone sites. I-Shift containers are fully populated in Saft’s factories and use a modular approach embedding batteries, thermal systems and digital control interfaces connecting to Saft’s cloud- based data platform ‘I-Sight’.
