Atlas Copco takes sustainability to new levels with hybrid power solutions

19 May, 2022

The new range of Energy Storage Systems from Atlas Copco maximises sustainability for operators by working in hybrid mode with efficient diesel-driven generators. This solution helps them cover power peaks and low loads – extending their lifespan and providing a rapid return on investment (ROI).

Energy storage solutions featuring long-life, low maintenance, and highdensity Lithium-ion (Li-on) batteries, working in hybrid mode with dieseldriven generators are the perfect solution for companies operating in demanding and noise-sensitive applications like metropolitan construction and events. These hybrid power solutions help them meet the toughest sustainability targets while achieving maximum levels of productivity and efficiency.

Ideal for high-demanding applications that require a continuous flow of clean and quiet energy, including residential, commercial, industrial, or public services, Atlas Copco’s range of Energy Storage Systems offers users 40,000 hours of uninterrupted operation and an overload capability of 150%. These units can operate autonomously for up to 12 hours and rapidly recharge in 1.5 hours. And its first-in-class Lithium-ion batteries are capable of working in temperatures between -20degC to 50degC.

Nearly 70% more compact and lightweight than traditional alternatives, these Energy Storage Systems can achieve a completely green solution while operating in island mode, registering zero CO2 emissions and zero noise. When working in hybrid mode, together with a generator, they optimise the solution, reducing noise levels and fuel consumption. This makes all the models of the ZenergiZe Energy Storage Systems range – ZBP45, ZBE45, ZBC 100-575, ZBC150-575, ZBC250-575, ZBC300-300, and ZBC500-250 – particularly suited to urban environments with noise level restrictions, events, telecoms, and rental applications. Operators can now work with minimum downtime for extended periods, including well into the night if required. Additionally, Atlas Copco’s Energy Storage Systems can store and deliver energy from renewable sources, like solar or wind.

Offering the most efficient hybrid alternative to using a large generator for variable loads is the combination of Atlas Copco’s Energy Storage Systems (ZBP and ZBC models) and the company’s latest QAS+ generators. Compared with a generator of 650 kVA, working as a standalone solution, a ZBC250-575 with a QAS+ 325 in hybrid mode can reduce daily fuel consumption by up to 80%. It is equivalent to approximately 200 CO2 tons during their working life. This has a significant impact on productivity, boosting it by 50% and keeping the solutions’ Total Cost of Ownership (TCO) to an absolute minimum.

Optimised performance

Atlas Copco’s Energy Storage Systems optimise the generator’s performance, extending its lifespan by up to 15% and cutting in half any maintenance and overhaul requirements. At the same time, the QAS+ features a built-in power management system that enables rapid and efficient paralleling, ensuring optimal fuel consumption levels and eliminating the need for generators to run with low load levels.

The generators QAS+ are Stage V compliant and Atlas Copco’s most efficient and sustainable diesel generators. Also, the QAS+ range is, on average, 5-8 dBA quieter than comparable generators and can reduce noise levels by up to six times, depending on the application and the load profile. With a footprint up to 25% smaller than its peers, the QAS+ is easy to transport and use on-site, offering straightforward plug-and-play connectivity. The generator also features a smart VSD (Variable Speed Drive) motordriven fan. It adjusts the cooling flow to the specific requirements of the engine. It minimises power loss to cool the engine and contributes to superior levels of fuel efficiency. Other features of the QAS+ generator include a user-friendly touchscreen and up to eight sockets, a terminal board, and optional power locks. While the hybrid solution offers optimal benefits to operators, an additional feature of Atlas Copco’s Energy Storage Systems is that they can run with any generator and a single generator can be used with multiple battery-driven units.

Barbara Gregorio, product marketing manager, innovative energies & digital solutions at Atlas Copco’s Power and Flow division, says: “Sustainability is more important than ever in an increasing number of highly demanding industry sectors. Our range of Lithium-ion Energy Storage Systems offers the perfect hybrid power delivery and management solution when used with our advanced QAS+ generators. Operators who have been looking to slash their carbon footprint while at the same time reducing their Total Cost of Ownership (TCO) and minimising their return on investment (ROI) periods now have just what they require.”
