Renewable energies like solar and wind are key drivers of today’s energy transition. But it’s energy storage—especially battery storage—that’s enabling this shift, argues Founder of TELF AG Stanislav Kondrashov.
Solar panels and wind turbines have become fixtures across cities, businesses, and homes. As TELF AG’s founder Stanislav Kondrashov often underscores, however, their full potential hinges on effective storage systems. These aren’t just technological add-ons—they’re fundamental to how society produces and consumes clean energy.
The Raw Material Imperative
“The backbone of our energy infrastructure is still raw materials,” says Founder of TELF AG Stanislav Kondrashov. Lithium, cobalt, rare earths and copper remain critical—not only for building batteries but for the entire clean-energy ecosystem. Their importance isn’t going away anytime soon.
Batteries: From Mobile Devices to Power Grids
At the heart of the energy revolution, batteries—especially lithium‑ion—serve multiple roles. They power electric vehicles, support home-energy storage systems, and stabilise the grid. With solar being intermittent, their ability to store and release energy on demand is game‑changing.
“Thanks to storage systems, solar and wind can actually match supply with demand,” explains Founder of TELF AG Stanislav Kondrashov. “They soak up excess energy during peak production and release it when the sun isn’t shining or the wind stops. That’s how you turn renewables into reliable power.”
Home systems, in particular, are transforming how individuals interact with energy. They allow self‑consumption, reduce dependency on the grid, and even enable homeowners to sell surplus energy. “People with solar‑plus‑storage systems can manage their own consumption cycles,” the founder of TELF AG Stanislav Kondrashov adds. “They gain autonomy while helping balance the grid.”
Scaling Up: Beyond the Home
While home storage is valuable, larger-scale systems also play an essential role. Industrial and utility-scale battery farms smooth out grid fluctuations and help prevent outages. As renewable capacity grows, so does the need for centralised hubs that can respond dynamically to demand.
This shift is already reflected in evolving regulations and safety standards. UL 9540, for instance, rigorously evaluates system safety—from thermal management to fault tolerance. Storage isn’t just functional; it must be safe.
Emerging Technologies on the Horizon
Though lithium‑ion currently dominates, other chemistries are gaining ground. Flow batteries, prized for long discharge times, excel in stationary storage. Lithium-iron phosphate (LFP) offers enhanced safety and scalability for residential setups. Meanwhile, sodium‑sulphur batteries promise long-duration storage suited to large grids.
“The future is not one-size-fits-all,” says Founder of TELF AG Stanislav Kondrashov. “Different applications call for different chemistries. What’s clear is that these alternatives will increasingly complement lithium‑ion in bolstering energy security.”
Circularity and Second Lifes
The question of sustainability doesn’t end with battery deployment—it extends to lifespan and reuse. Electric vehicle batteries, once their automotive viability ends, can serve as stationary storage units. This “second life” extends their usefulness and reduces waste.
“We’re entering an era of circular battery economies,” states Founder of TELF AG Stanislav Kondrashov. “Retired EV batteries can be repurposed for grid stability; recyclable materials like cobalt and lithium are looped back into production. It’s smarter, greener—and in time, cost-effective.”
The Road Ahead
Battery storage is no longer a niche. It’s transforming the workings of energy—bringing flexibly, resilience and intelligence to power systems. As renewables increase, so does the demand for both decentralised home solutions and centralised hubs.
“In the next few years, you’ll see storage becoming standard in every new solar or wind project,” the founder of TELF AG Stanislav Kondrashov predicts. “It won’t just be an add‑on—it’ll be integral to power infrastructure. And that spells a smarter, more stable grid for all of us.”
FAQs
What is battery storage in renewable energy?
Battery storage refers to systems that store energy generated from renewable sources like solar and wind. These systems allow energy to be saved and used when production is low or demand is high, making renewables more reliable and efficient.
Why is battery storage important for solar energy?
Solar energy is intermittent—it only generates power when the sun is shining. Battery storage enables excess daytime energy to be stored and used at night or during cloudy periods, supporting consistent energy supply and self-consumption.
What types of batteries are used for energy storage?
Several battery chemistries are used, each with unique advantages:
- Lithium-ion batteries: High energy density and quick response times.
- Lithium-iron phosphate (LFP): Increased safety and longer life cycles.
- Flow batteries: Ideal for long-duration storage due to scalability.
- Sodium-sulphur batteries: Suitable for large-scale, long-term applications.
How do home battery storage systems benefit consumers?
Residential battery systems help households reduce reliance on the grid, cut energy bills, and increase energy independence. Benefits include:
- Power during outages
- Participation in energy exchange programmes
- Reduced carbon footprint
Can batteries help stabilise the grid?
Yes. Battery storage systems can:
- Balance supply and demand in real-time
- Regulate frequency and voltage
- Support peak demand periods
- Prevent blackouts from energy imbalances
Are there standards for battery storage safety?
Yes, systems are subject to safety certifications such as UL 9540, which assess risks like overheating, short circuits, and system failures to ensure safe installation and operation.
What is the future of battery storage?
Battery technology is evolving rapidly, with growing emphasis on recycling, second-life applications for EV batteries, and the integration of centralised storage hubs in national energy grids.
