Reseña del libro "The Carbon Battery. Long Term Green Energy Store (en Inglés)"
1. Why the Carbon Battery is Needed
1.1 The Problem
Countries pursuing Net Zero aim to eliminate greenhouse‑gas emissions, principally carbon dioxide and methane. Today these gases are released whenever fossil fuels are burned to power industry, homes, and transport. Renewable energy - wind, solar, hydro, tidal, geothermal - offers a clean alternative, yet in the UK and many other nations natural gas remains a dominant energy source and a major contributor to emissions.
Achieving Net Zero in the UK requires replacing this gas demand with low‑carbon electricity. On average, around 14% more power would be needed, and crucially it must be available as Firm Energy: supply that can be dispatched or withheld on demand. Nuclear cannot provide this flexibility, operating instead at a constant output. Wind and solar cannot guarantee availability, falling to very low levels during calm, dark winter periods. During these extended deficits, the system requires a dependable reserve.
Existing storage technologies - lithium batteries, hydrogen, compressed‑air and gravity systems - can bridge short gaps of hours, but not the multi‑day or multi‑week shortages that occur during prolonged low‑renewable periods.
A further challenge is curtailment. Transmission constraints on the National Grid already force large volumes of wind generation to be switched off because power cannot be moved to where it is needed. As The Times highlighted on 10 January 2026 in "How wasted wind pushes up bills", this wasted energy raises costs for consumers. Curtailment will worsen as renewable capacity expands toward 2030.
The UK therefore faces a dual problem:surplus renewable electricity that cannot be used, andinsufficient long‑duration storage to cover periods up to a month without wind or sun. However many wind and solar farms are built, during calm or darkness there will be a power blackout. A strategic, seasonal‑scale energy store is required.
2. How the Carbon Battery Meets This Need
The Carbon Battery is a Long‑Term Green Energy Store (LT‑GES) that provides the UK with a seasonal, dispatchable, zero‑carbon energy reserve. It operates entirely on renewable electricity, salt‑cavern methane storage, and a fully circular carbon loop.
Unlike conventional carbon‑capture approaches, LT‑GES does not dispose of CO₂. Instead, the CO₂ produced during methane discharge is captured, frozen into dry ice, stored on site, and fully recycled into methane during the next charging cycle. Carbon becomes a strategic asset - a stable, inspectable, high‑purity feedstock essential to system operation - rather than a waste stream requiring geological disposal.
This makes LT‑GES the first closed‑loop, zero‑loss, carbon‑retention energy system, avoiding the environmental, regulatory, and public‑acceptance challenges associated with long‑term CO₂ burial.
