Freetown gravity energy storage

What is gravity energy storage?

Gravity energy storage is a new technology that stores energy using gravity. It has the potential to be a cornerstone of sustainable energy systems, with its capacity for long-term energy storage and low maintenance. It’s also cheaper than other alternatives, which positions it as a strong candidate for grid-scale applications. How it works

Is gravity energy storage viable in Malaysia?

Gravity energy storage offers a sustainable long-term option that can complement other storage systems and help balance supply and demand on the grid. Underground gravity storage systems in Malaysia are viable given the many abandoned mining sites including those in Tronoh, Batu Gajah, and Bestari Jaya.

How can government and private sector support gravity energy storage?

One way forward is for governments and private sector stakeholders to support pilot projects to showcase the practicality and scalability of gravity energy storage technology. These initiatives will provide valuable data on performance in real-world scenarios and help refine the technology for wider adoption.

How long do gravity energy storage systems last?

For one, gravity energy storage systems can last for decades with minimal maintenance, unlike batteries that degrade over time. Environment-wise, gravity energy systems avoid harmful chemical reactions, reducing environmental impact and disposal issues, an important consideration in the move towards a greener planet.

How can public-private partnerships improve gravity energy storage?

Focus areas include optimising the size and weight of the masses used in gravity energy storage systems and exploring alternative materials. Public-private partnerships can address the financial and technical challenges of deploying gravity energy storage at scale.

Is gravity energy storage better than battery energy storage?

Gravity energy storage can also be more cost-effective for large-scale applications, with lower-level costs of energy and storage. A recent study found that while gravity energy storage and battery energy storage increased solar energy penetration by up to 7.26%, the former outperforms the latter in lifetime costs and energy efficiency.
