Battery Circularity
…into the key issues for battery technologies, the report presents the very latest data as a guide to decision makers from the public and private sectors. It sheds light on the main locations of patenting, the leading patentors in the world and the technology categories receiving the most innovation attention.More than one in four cars sold globally in 2025 was an electric vehicle, reliant on lithium-ion or other modern batteries. But around 1.2 million electric vehicle batteries could reach the end of their lives in 2030 and 14 million in 2040, and today’s supply chains for…

Asset values
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores asset values. Why is energy efficiency important for asset values? Energy efficiency can increase the value of assets, such as homes, buildings or equipment, and lead to lower vacancy rates and longer equipment lifespans. Key facts Energy efficient buildings can command a premium on sale and rental price in both the residential and commercial sectors. Studies show that sale price premiums for energy efficient buildings range from 3% to 15% in residential buildings and 13 to 20% in commercial buildings. Key analysis Studies show that individuals…

Financing CCUS at Scale
How to Mobilise Private Capital Carbon capture, utilisation and storage (CCUS) is an important area of attention for governments and financiers as both look to balance policy and investment goals. Recent financial investment decisions of major projects show promise in a sector that is gaining momentum, but its future success depends on viable business models and effective risk allocation across the value chain.In this context, Financing CCUS at Scale is the IEA’s latest report on what it takes to move CCUS projects from the drawing board to operation. Building on expert interviews with leading financial institutions, the report…

Multiple Benefits of Energy Efficiency for Business
Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone. However, the value of energy efficiency extends beyond energy savings.This report builds on the IEA’s work on the multiple benefits of energy efficiency and focusses on how these gains materialise in businesses. Key benefits range from productivity and product quality improvements to brand image or health benefits for employees and…

Responding to Satellite Notifications from the Methane Alert and Response System
…potentially reducing gas waste, boosting sales by domestic companies and improving national energy security while simultaneously decreasing air pollution, minimising local health impacts and increasing productivity. More broadly, it may allow governments to achieve national emissions reduction objectives. While the response rate to MARS notifications has increased since the system’s introduction in 2023, overall engagement remains low: globally, only around 12% of MARS notifications received a response in 2025. This suggests that further support mechanisms may be needed to ensure satellite alerts translate into effective mitigation responses.This technical guidance document is designed to assist governments seeking to improve…

Vehicle-to-grid technology
…EV batteries become flexible assets for energy storage rather than mere loads to the grid. There are varying degrees of flexibility. With unidirectional smart charging (V1G), the charging power can be modulated to align electricity demand with generation profiles or to alleviate grid congestion. With vehicle-to-building (V2H/V2B), the EV can additionally discharge energy for use in a home or building, either to serve as a backup during power outages or to lower electricity bills by leveraging dynamic tariffs and increasing self-consumption of rooftop solar. Finally, V2G technology can push energy from the EV battery into the…

Autonomous vehicles
…architectures, pioneered by EV makers, provide a clear edge. The mutually reinforcing trends of software‑defined vehicles and automated driving are therefore consolidating the technological leadership of EVs. Partially automated driving is becoming mainstream while autonomous vehicles are starting to gain traction Over the past 10 years, ADAS have become much more widespread. In 2025, around half of new cars sold globally featured systems that can automate steering and speed control (Level 2 automation), whereas 10 years earlier this was limited to very few high-end models, accounting for less than 1% of sales. However, the most commonly deployed systems, like…

Heat Pump Taxonomy
A common framework for heat pumps classification and data Heat pumps are a cornerstone technology for achieving secure, affordable and sustainable heating. They have become one of the most common heating technologies and have the potential to impact significantly future trends for energy consumption in buildings and beyond.Tracking and analysing the pace of heat pump deployment compared to that of conventional heating technologies is essential for understanding future needs with regards to energy demand, investments in electricity infrastructure and fuel supply.Despite their growing importance, data on heat pump installations, as well as on their performance and cost, remain…

Ultra-fast charging batteries
GEVO 2026 - Chapter 8 New power‑electronics materials, battery cell technologies and battery pack architectures are enabling more efficient, higher‑voltage – and therefore faster – charging systems. Advances in batteries and power electronics are improving EV performance Over the past decade, average EV battery pack energy density (Wh/kg) has increased by around 60%, while prices have fallen by roughly 75%. Moreover, in 2023, battery-related patents accounted for 40% of all energy-sector patents, suggesting that more developments are still to come. At the same time, new power‑electronics materials, battery cell technologies and battery pack architectures are enabling more efficient, higher‑voltage – and…
