Meet Unit45, a leading Rotterdam-based company specializing in developing and delivering 45ft palletwide containers tailored to customer-specific requirements. These containers are key to future logistics challenges and are fully compliant with European standards. As an “Intermodal Innovator” and market leader, Unit45 is distinguished by innovation and the use of quality materials for their 45ft container concept.

Unit45 serves an impressive customer portfolio, including A2B-online, P&O Ferrymasters, Bulk Logistic Solutions BLS, DSV, ECS European Containers, JSV Logistic, CLdN Cargo, Containerships and GVT. Their approach is a direct response to the EU need for harmonization and standardization in transport, as highlighted in the 2001 Transport White Paper. Traditional 20 and 40ft containers lack optimal payload capacity for ISO pallets and do not fully utilize the maximum dimensions allowed for land transport, while swap bodies are limited in strength and seaworthiness.

Unit45’s highcube palletwide containers combine the advantages of both containers and swap bodies and are a perfect solution for intermodal transportation. These containers, which can also be loaded sideways, are ideal for current and future infrastructure needs, offering an efficient, sustainable alternative to conventional transport. Unit45 continues to innovate and pave the way for a more efficient and sustainable transportation industry.

We’d like to introduce you to Sunsynk Mobile, a revolutionary new division of Sunsynk focused on providing high-quality, mobile energy solutions. Sunsynk Mobile is a game-changer in the world of compact power supply, ideal for a wide range of applications, from small remote devices to large industrial facilities. Their systems guarantee reliable and continuous power regardless of your location.

For places such as construction sites, temporary housing, portocabins and construction offices, where there has traditionally been high consumption of electricity from fossil fuels, Sunsynk Mobile offers a sustainable alternative. Their efficient inverters, renewable lithium phosphate battery systems, and solar or wind power generators are not only more environmentally friendly, but also help reduce both air and noise pollution. This helps reduce dependence on expensive fuels and provides an economically advantageous solution.

The Mission of Sunsynk Mobile
Their goal is to design solutions that perform reliably and continuously in diverse environments, with sustainability and efficiency at the forefront. Sunsynk Mobile is dedicated to providing energy solutions that are not only powerful and versatile, but also support a greener future.

Power grid imbalance

A battery container is vital for managing grid imbalance by storing energy and releasing it when needed, enabling peak smoothing, demand cutting and energy arbitrage. This allows companies to take advantage of price fluctuations.

FCR delivery requires a frequency meter on the equipment, which continuously measures the grid frequency. When deviating from the standard frequency of 50 Hz, the equipment adjusts the power output: an increasing frequency reduces the power supply or charges the battery, and a decreasing frequency increases the power output or injects energy into the grid.

Battery containers can thus offer their flexible power as backup for grid stabilization and receive compensation for it, regardless of whether the battery container is actually deployed by TenneT. In this way, one can earn without degrading the battery. During this period, the battery owner cannot trade with price fluctuations. Participation in a pool is most interesting when there is little grid imbalance.

However, with significant imbalance, using battery containers for trading in the FCR market may be more advantageous. Indeed, in this market, with 4-hour blocks, price differences can range from €200 to €500 per MWh or even more. This can lead to faster payback and fewer charge cycles per year compared to a dynamic energy contract. In the FCR market, the greater the storage capacity, the higher the potential returns.

As of July 1, 2024, employers with more than 100 employees must track the CO2 emissions of their workforce, as part of the goal to reduce 1.5 megatonnes of CO2 by 2030. In this context, battery storage systems play a crucial role in helping companies reduce their carbon footprint. This is critical given the upcoming tax on carbon emissions.

Furthermore, the versatility and flexibility of our EMS enables accurate energy monitoring, which can be used for utility bill verification, carbon audits and both energy and carbon trading. This technology can be deeply integrated into energy systems, where it measures and evaluates energy profiles of process equipment and machinery. This allows further energy efficiency and reduction measures to be integrated into the system, contributing to the overall reduction of the carbon footprint and meeting climate goals.

Energy hubs can be a solution if you cannot fully utilize your maximum connection capacity. Several companies can join a centrally located battery storage system, also called an energy hub. Each company has its own maximum contracted capacity for offtake and injection. Thanks to our smart software, electricity is distributed as optimally as possible to all connected parties. This means that even if you experience limitations in, for example, power injection to the grid, you can still achieve more independence and be more efficient with your power in cooperation with your neighbor. For example, you can sell your generated solar power to your neighbor at a more favorable rate than to the grid, while your neighbor pays less for this power than he would when buying from the grid.

This graph provides a complete overview of your daily energy consumption and injection, as well as the charging and discharging process of your battery.

This graph illustrates frequent charge cycles in which the battery is ideally fully charged to 100% and then discharged to 10-20%. This promotes payback and increases battery container yields.

This graph shows energy withdrawal and injection into the power grid, taking into account the maximum connection capacity and contracted power. The model reflects the practical limits of energy use and return, providing a realistic picture of energy flows.

This diagram clearly shows the times when the battery is full (indicated in green) and empty (indicated in red). Ideally, one aims for a balanced 50/50 split between full and empty, indicating full charge and discharge of the battery container. This has a favorable impact on both payback time and yields. Furthermore, it can be seen that battery performance decreases in the winter months, which is related to the lower solar yield during this period.

At a load of ≤ 30%, the efficiency is ≥ 98%, and at a load of > 50%, the efficiency is ≥ 99%.

Currently, there are no specific subsidies available for large-scale energy storage. However, you may be able to take advantage of the Energy Investment Allowance (EIA) for home batteries at businesses.

You can use up to 5 parallel machines.

The TL DC-500/0.4 model is designed to operate with an AC input voltage of AC380V (ranging from -10% to +10%).

The noise level during operation is less than 65 dB.

The battery container quickly switches to controlled voltage source mode to ensure uninterrupted power to the equipment.

In case of a load higher than 1.5 times the rated load, battery container immediately switches to bypass mode to protect the equipment.

There are currently no specific subsidies available for the purchase of battery containers in the Netherlands for individuals.

Perhaps, take the test at the link below.

The Energy Investment Allowance (EIA) is a Dutch tax scheme that offers companies tax benefits for investments in energy-efficient and sustainable technologies. Up to 45.5% of investment costs can be deducted from taxable profit. This will encourage sustainable investments and reduce tax burdens.

New subsidies or incentives may be introduced in the future. We always strive to keep you as informed as possible.
