Absorbent Glass Mat (AGM) and Gel batteries are the latest advancements in lead-acid battery technology. . The lead-acid (PbA) battery was invented by Gaston Planté more than 160 years ago and it was the first ever rechargeable battery. In the charged state, the positive electrode is lead dioxide (PbO2) and the negative electrode is metallic lead (Pb); upon discharge in the sulfuric acid electrolyte. . The lead acid battery has been a dominant device in large-scale energy storage systems since its invention in 1859. It has been the most successful commercialized aqueous electrochemical energy storage system ever since. While they face competition from newer battery technologies such as lithium-ion, lead-acid. .

Spain has launched an ambitious €700 million (around $796 million) program to increase its energy storage capacity. This plan will add 2.5 to 3.5 gigawatts (GW) of storage. It includes pumped hydro, thermal energy storage, and battery systems.
For stakeholders in battery storage, thermal storage, and pumped hydro, this program offers not only financial backing but also long-term stability and political support. Spain has launched a €700 million energy storage program to support battery, thermal, and pumped hydro projects, aiming to deploy 2.5–3.5 GW of capacity.
Spain has taken a decisive step in strengthening its energy infrastructure with the launch of a €700 million support scheme aimed at expanding large-scale energy storage across the country.
Investing in energy storage helps Spain meet its climate goals. This includes achieving carbon neutrality by 2050. Storing renewable energy instead of wasting it helps the country rely less on fossil fuels. This also cuts down greenhouse gas emissions. Pumped hydro, thermal storage, and battery systems are effective technologies.
