About 247 Energy - 247 energy storage

Innovations

We focus on innovative products! Tackling the issues of lithium batteries : safety (potential fires) and extending life cycles (10 to 45 years) is groundbreaking.

Long Life

A battery that lasts 50.000 cycles! 100% recyclable, a green non-chemical product.

Safety first

Lithium batteries are not safe, they burn and the fires are very hard to kill. Therefore we offer non chemical batteries that are safe to install in homes, cars, industrial applications (hospitals, planes, trains).

Engineering

We design and assemble our products in-house to deliver top quality and answer to every need of our professional customers.

Why is energy storage so important

Clean, renewable energy sources are needed to create a sustainable society. They need to displace our current dependence on more problematic energy sources such as oil, natural gas and uranium. The problem with such renewable energy sources is that they may not be produced when they are needed most – at times of greatest energy demand. The production of energy from such sources depends on environmental conditions. Wind energy is used when it is windy, and solar energy production depends on solar radiation.

Such challenges require a storage solution such as batteries. They allow renewable energy generation to be stored until it is needed.

A bright future for energy storage.

Energy storage offer a viable solution for storing intermittent energy supply in conjunction with renewable energy. Costs are falling while production is rising, and they offer hope for a future tied to clean renewable energy.

Is lithium-ion future-proof and sustainable? We firmly believe that it is not. That is why we are introducing a new technology that is far more sustainable and solves other important problems with lithium-ion batteries: safety and life cycles.

Inadequate grid infrastructure

A remodeled grid will be needed to facilitate the balancing of associated intermittent flows on the system when the wind isn’t blowing and the sun isn’t shining. Unlike renewable generating facilities, transmission projects can take up to 10 years to complete, from conception through regional planning processes, to national approvals and then ultimately to the construction phase.

The disadvantages of the Li-ion battery

Protection required: Li-ion cells and batteries are not as robust as some other rechargeable technologies. They need to be protected from overcharging and excessive discharging. In addition, they need to keep the current within safe limits. Accordingly, a disadvantage of lithium-ion batteries is that they require built-in protection circuitry to ensure that they are kept within their safe operating limits. The protection circuit monitors the cell temperature to avoid temperature extremes. The maximum charge and discharge current is limited to a temperature between 1°C and 2°C for most batteries. Nevertheless, some batteries do occasionally get a little warm during fast charging.
Aging: One of the biggest disadvantages of lithium-ion batteries for consumer electronics is that lithium-ion batteries suffer from aging. This is not only time or calendar dependent but also depends on the number of charge-discharge cycles the battery has undergone. Often, batteries can only withstand 500 – 1000 charge-discharge cycles before their capacity starts to deteriorate. With the development of Li-ion technology, this number is increasing, but after a certain amount of time the batteries need to be replaced and this can be a problem if they are built into the devices. Lithium-ion batteries also age when they are in use or not. Despite use, there is also a time-dependent element to the reduction of capacity.
