Investment in next-generation geothermal is surging. Policies are key to further growth
Next-generation geothermal readies for take-off Next-generation geothermal is seeing a burst of financing, innovation and new supply agreements Geothermal energy harnesses naturally occurring heat found beneath the Earth’s surface to provide heating and cooling, electricity and energy storage. As global electricity demand rises and power systems place a growing premium on firm supply, geothermal energy’s ability to provide an around-the-clock, low-emissions source of power is attracting renewed attention. However, easy-to-access conventional geothermal resources are relatively rare and mostly confined to a small number of shallow geothermal hotspots globally, accounting for…

Wired for water: How electrification is transforming desalination
Wired for water: how electrification is transforming desalination The water-energy nexus Pressure on water resources is increasing worldwide and can be very acute at the local level. Rising consumption across sectors combined with population growth in already water-stressed regions is intensifying water scarcity. Desalination has long been developed to supply fresh water in the most affected areas, with significant implications for the energy system: energy use ranges from under 0.1% to as much as 15% of total final consumption, depending on national reliance. However, a shift is underway from thermal desalination technologies to electricity-driven systems as…

Sodium-ion battery momentum grows, but challenges remain
batteries commentary sodium batteries Recent technological advances and investment announcements suggest dynamics are shifting for sodium-ion batteries Sodium-ion batteries are emerging as a new player in battery markets, offering opportunities to diversify battery chemistries and supply chains at a time of rising global demand for electric vehicles and energy storage. Developed in laboratories since the early 1980s, sodium-ion batteries operate on the same fundamental principles as lithium‑ion batteries – which currently dominate the market – yet their path to commercialisation has been markedly slower.While lithium-ion batteries entered commercial use in the 1990s – with the first electric vehicles…

What it would take to unlock the next phase of hydrogen growth
Can hydrogen scale up successfully Global hydrogen demand reached 100 Mt in 2024, mainly from refineries, the production of chemicals and the iron and steel sector. Demand grew by almost 2% from 2023, in line with overall energy demand growth. This consumption was almost completely met with hydrogen produced from unabated fossil fuels, using 290 billion cubic metres of natural gas and 90 million tonnes of coal equivalent. However, alternative technologies that can produce low-emissions hydrogen have attracted a lot of interest from governments given their potential to reduce greenhouse gas emissions and diversify energy supply, particularly in countries that have a…

Policy and financing momentum sustain CCUS progress despite setbacks
CCUS Projects Database 2026 commentary Efforts to expand carbon capture, utilisation and storage (CCUS) took some important steps forward in 2025. Despite delays and cancellations in some areas, projects reached notable milestones in key markets, while growing financing provided further momentum.CCUS deployment in Europe saw a step-change as the world’s first dedicated carbon dioxide CO2 storage hub began operating in Norway. Major projects were also commissioned in China and North America, and the construction of new facilities began in eight countries worldwide. The newest annual update to the IEA’s CCUS Project Database – which incorporates developments between…

India’s electricity demand grows at night: Managing rising cooling demand
India cooling commentary As India’s cooling demand surges alongside solar power capacity, ensuring sufficient nighttime power capacity is key Power consumption in India is on the rise amid economic and population growth, as well as the growing use of air conditioning as more households purchase units and temperatures increase. Since 2019, the country’s electricity demand has increased by 5% per year. While electricity supply has kept pace, solar PV has accounted for two-thirds of power capacity additions in India since 2019. Against this backdrop, ensuring adequate power generation capacity during periods of peak demand is emerging as…

Battery storage is scaling up and taking on a larger system role
Commentary As the result of falling costs and greater flexibility needs, battery storage is playing a growing role in power systems worldwide, acting as a “multi-tool” that can provide a range of critical system services at once. According to the latest data, the deployment of batteries expanded strongly in 2025 and broadened across markets – with rapid growth in countries such as Australia and Saudi Arabia, where storage is increasingly being used to support the integration of rising shares of variable renewables.In regions that have been at the forefront of renewable integration and battery deployment, batteries now play an…

Delivering on the EU’s electrification ambitions
EU paper The EU has ambitious goals for electrification Electrification is a key pillar of the EU’s energy security, industrial competitiveness, and climate strategy. Today, imported fuels account for around 60% of the EU’s total energy demand and cost the bloc EUR 380 billion in 2024. The risks associated with the EU’s reliance on fuel imports have been highlighted by recent market disruptions linked to the near-closure of the Strait of Hormuz amid the conflict in the Middle East, bringing renewed attention to the EU’s target of increasing electrification from 24% today to 32% of…

Global battery markets are growing strongly – and so are the supply risks
part 1- lithium-ion batteries Batteries’ importance is increasing across key sectors including autos, power, data centres and beyond The global lithium-ion battery market exceeded USD 150 billion in 2025, an increase of over 20% from 2024, but its economic and strategic significance extends far beyond market size. Batteries are becoming a cornerstone of the automotive sector, a critical source of flexibility for power systems, and an increasingly important source of back-up power for digital infrastructure, including data centres and artificial intelligence.Beyond energy, batteries remain indispensable for a wide range of industrial and strategic applications, from portable…

Why the growth of energy service companies is uneven globally
ESCO The global annual ESCO market growth rate has more than doubled over the past five years Energy efficiency is one of the most cost-effective tools for enhancing energy security, reducing household energy bills and supporting countries’ efforts to reduce emissions. Energy service companies (ESCOs) – firms that develop and implement energy efficiency projects typically financed through verified energy savings – are playing a growing role in delivering energy efficiency improvements across buildings, industry and transport infrastructure worldwide. By integrating project development, financing and performance guarantees, ESCOs can offer a proven way to reduce upfront investment barriers and shift technical and…
