An Israeli startup wants to store electricity at the bottom of the sea

The startup BaroMar has created a groundbreaking technology for underwater energy storage. Their innovation involves compressing air in a tank and releasing it to generate electricity, which is believed to be a more efficient solution than existing methods in this field.

In usual circumstances, technology like this would demand extensive reservoirs or geological structures, like depleted natural gas deposits, which are not readily accessible. However, the Israeli company has introduced an innovative solution: they suggest using the seabed as a storage site for compressed air. This approach offers a promising alternative in the absence of traditional storage options.

Simple and effective storage of electricity

As per the project’s core principles, any surplus electricity generated by renewable sources is directed towards powering the compressor. When there is a need for electricity, the compressed air is transported back to the shore, where it drives a generator to meet the demand.

The startup’s proposed solution is environmentally friendly, as it solely relies on surplus energy from renewable sources, ensuring emissions neutrality. Furthermore, the land infrastructure required for this technology is minimal, and the concrete tanks would be positioned at a depth of 500 meters, resulting in minimal disruption to marine life.

This technology aims to revolutionize energy storage by offering significantly longer storage durations compared to current solutions, potentially spanning many months.

Challenges facing a startup

The primary hurdles encountered are linked to the varying and often ambiguous legal regulations governing seabed construction. Additionally, there is a need to refine the engineering processes for establishing these facilities, all while ensuring stringent safety standards are met.

In contrast to many other electricity storage innovations that remain confined to the laboratory research stage, the startup’s technology has demonstrated real-world effectiveness. Yonadav Buber, the CEO of the Israeli company, highlights this as a significant advantage over competitors in the field.
