FAQ
On this page you will find everything you need to know about energy storage, our battery systems, and how Moola can optimize your energy flows.
A battery can store electricity through a chemical reaction. Most batteries consist of two electrodes (one positive and one negative) and an electrolyte, which separates the electrodes. The reaction between the materials in the electrodes and the battery's electrolyte allows energy to be stored in the form of a potential difference between the two electrodes.
When charging a battery, the added electrical energy causes electrons to flow from the positive to the negative electrode. The accumulation of electrons on the positive electrode creates a potential difference. This potential difference is maintained because the electrolyte separates the electrodes and prevents the electrons from flowing back. The battery can power devices by connecting the electrodes via an external circuit. This gradually decreases the potential difference between the electrodes until it eventually reaches zero, and the battery is fully discharged.
The most common battery types used in energy storage systems are:
An energy storage system (ESS) offers the possibility of storing generated energy for future use and plays a crucial role in the transition to sustainable energy. It helps to compensate for fluctuations in the production of renewable sources, such as solar and wind. Energy can be stored in various ways, for example, in batteries (chemical), as hydrogen via electrolysis, in flywheels (mechanical), or in heat storage tanks (thermal).
These systems allow for more efficient use of energy production, reduce peak loads on the electricity grid, and improve stability. They also contribute to lower emissions by utilizing surplus renewable energy, both at home and on a larger scale for the grid.
Our technological edge is defined byLead Ultra Carbon Batteries (LUCB) chemistry.
By incorporating Engineered Carbon Nanomaterials, we create a "supercapacitor effect" that traditional batteries lack. This results in an ultra-high efficiency of 90-92%, superior thermal resilience, and a non-flammable, non-toxic design that eliminates common plate sulfation.
Load shifting refers to shifting electricity consumption to different times. This strategy helps to use electricity during cheaper periods and avoid higher prices, leading to cost savings. This can be achieved, for example, by shifting energy-intensive processes in factories and businesses to times when demand is lower, or by scheduling household appliances to run at specific times.
Load shifting is often combined with battery systems. In this setup, electricity is stored during cheaper hours and used later during the more expensive peak hours. This means the total amount of energy you draw from the grid doesn't change, but the times at which you draw it do. This not only offers financial benefits but also helps relieve pressure on the electricity grid during peak hours.
Going off-grid and independent of the electricity grid sounds appealing in theory, but in practice it's a challenge, especially in the Netherlands. This is mainly due to the limited amount of sunshine during the winter months, which results in insufficient energy generation from solar panels and therefore a shortage of electricity. Therefore, we recommend staying connected to the grid at all times.
However, with an Energy Management System (EMS), you can ensure optimal use of your self-generated energy. This system helps you use your own energy as efficiently as possible and minimizes the amount of electricity you draw from the grid. This allows you to get the most out of your energy solutions, even while remaining connected to the grid.
Grid congestion occurs when the electricity grid lacks the capacity to transport all the electricity generated. This can occur when electricity generation exceeds the grid's capacity, or when insufficient infrastructure is available to transport the energy to end users. This problem is becoming increasingly urgent as demand for electricity increases due to the growth of renewable energy sources.
To address these issues, grid operators can implement various measures. They can expand grid capacity, reduce electricity demand during peak hours, and deploy smart grid technologies. Examples include energy storage systems and demand response systems, which help optimize the balance between energy consumption and generation.
Battery systems offer a solution by supplying additional electricity during peak hours, allowing companies to better respond to their energy needs.
In addition, grid congestion can prevent companies from feeding their sustainably generated energy back into the grid. This leads to wasted energy, which is both financially disadvantageous and hinders the progress of the energy transition. Energy storage systems can address this challenge by storing the generated energy for later use, allowing companies to optimally benefit from their sustainable energy production.
Battery systems not only help address grid congestion but also contribute to lowering energy costs and increasing the reliability of the energy supply. By intelligently managing stored energy, companies can improve their operational efficiency and reduce their reliance on the grid.
If a (heavier) grid connection is not possible at the business location, this can have direct consequences for business operations. It can even mean the company cannot expand or resume operations, which has significant financial consequences.
A solution to this problem is the installation of a battery system with sufficient power and capacity. This allows the company to continue growing even when grid connections are limited. The battery system can store electricity from the grid or a solar panel (PV) system and make this electricity available when demand is higher.
This ensures the company always has access to the necessary amount of electricity, even during peak hours when demand is highest. This not only expands operational capabilities but also ensures a more reliable energy supply, allowing the company to better respond to its growth ambitions.
Imagine a company that has installed electric car charging stations to support its employees in their transition to sustainable mobility. However, during the mornings when many employees arrive, there's a peak in demand for electricity to charge all these cars. By implementing a battery system, the company can store the necessary energy overnight, when demand is lower and electricity prices are often cheaper. This way, the battery system can provide the extra power needed to power the charging stations during busy mornings. This ensures that all electric vehicles are charged in time without the company having to rely on a larger grid connection, which not only increases operational efficiency but also helps reduce energy costs.
If feeding power back into the grid isn't possible, a battery system offers an excellent solution. Throughout the day, the system collects excess electricity generated by the solar panels that isn't consumed directly by the business.
This stored energy can later be used without needing electricity from the grid. This allows the company to fully utilize its self-generated energy, preventing valuable energy loss and increasing the overall efficiency and sustainability of its operations.
An energy management system (EMS) is designed to optimize energy consumption and production. It does this by monitoring, analyzing, and regulating energy flows. It collects data from various sensors, meters, and devices connected to the system.
Using this collected data, the EMS can efficiently manage energy flows by automatically switching devices on or off. This can be done, for example, by deactivating equipment when it's not needed or by scheduling its use for times when energy consumption is lower.
In addition, the EMS is able to manage energy storage systems and optimize the use of renewable energy sources, such as solar panels and wind turbines.
The primary goal of an EMS is to save energy, increase energy efficiency, and reduce energy costs. Furthermore, the system contributes to lowering CO2 emissions and promoting operational sustainability.
A energy management system (EMS) focuses
solely on monitoring energy flows. This provides insight into
the battery system's operation and charging and discharging
processes, but it cannot control external functions. Unlike a
basic EMS, an advanced EMS is capable of establishing smart
connections with external devices and can even operate in the
energy market.
Imagine a company has a simple energy management system (EMS)
that only monitors energy flows, providing insight into the
performance of its solar panels and battery system, but does
not allow for automatic adjustments (Insight).
Unlike this basic system, a smart EMS can not only track these energy flows but also actively respond to energy market conditions (Insight + Action). For example, when energy prices are low, the smart EMS can automatically charge the battery system with cheap energy and store it for use during peak hours when prices are higher. This allows the company to save costs and manage its energy consumption more efficiently.

The EMS provides smart control of the battery system and can also connect with other devices, such as solar panels and charging stations, to improve overall energy efficiency.
The payback period of a battery system varies depending on several factors, such as the purchase cost, the battery's storage capacity, energy prices and any available subsidies.
In general, the payback period is currently expected to be between 5 and 15 years, depending on specific circumstances.
