The challenge is not the production of sustainable energy—we can generate enough. The problem lies in our inability to store it effectively to meet fluctuating demand.

Onshore or Offshore wind and solar

The company has developed an innovative, highly efficient solution for long-duration energy storage (LDES) that is both cost-effective and scalable. This system is fully costed, peer-reviewed, affordable, simple to construct, long-lasting, non-toxic, and free from reliance on rare earth metals.

It addresses renewable energy intermittency, eliminates constraint payments, and lowers system balancing costs. Additionally, the system can decentralise the power grid by enabling intelligent regional storage, helping to mitigate costly network upgrades, estimated at £65bn and strengthening the resilience of the Critical National Infrastructure (CNI) to avoid problems experienced by the EU recently.

This British-designed, UK-patented innovation has worldwide applicability and aligns perfectly with the UK Government's commitment to making Britain a zero-carbon energy superpower by 2030.

The standard LDES module stores 250MW and is easily adaptable to various applications, such as storing energy from offshore or onshore wind farms during periods of over-generation, reducing renewable energy intermittency, and providing regional storage to enhance the flexibility and capacity of the national power grid.

Backed by experienced engineers and lauded by industry leaders as "extraordinary and game-changing," Our LDES is scalable to gigawatt levels, has a round-trip efficiency comparable to the best available technologies, requires no rare earth materials, and offers a 40+ year operational lifespan. Crucially, our system is estimated to be up to 30 times more cost-effective than lithium-ion batteries, making it a practical solution to the intermittency of wind and solar energy. Looking at the UK market, the projected system balancing and constraint costs—estimated at £2.4 billion and £3.5 billion respectively by 2026—underscore the need for scalable LDES. Left unchecked, these costs could exceed £33.7 billion by 2030. A cost-effective, scalable storage solution such as ours offers a compelling opportunity to mitigate these expenses while accelerating the energy transition. Driven by a philosophy of continuous improvement, Improved Energy’s aim is not only to make an impact but to revolutionise the energy industry. With unwavering passion, persistence, and collaboration, we are at the forefront of advancing a cleaner, more sustainable future.
