There is now more installed energy storage capacity than nuclear in Europe, yet ‘no country has reached its potential’

Curated by Shubham · TechCapsules · Jun 22, 2026

AI-summarised brief · reviewed before publication

Installed energy storage capacity in Europe has surpassed nuclear capacity, with a record 13.5GW/26.4GWh of new electrochemical energy storage deployed in 2025. Cumulative installs reached 102.7GW by the end of 2025, overtaking Europe's 105GW nuclear fleet in the second quarter of this year. Legacy pumped hydro energy storage accounts for around half of the installed capacity, while electrochemical storage, mostly lithium-ion batteries, makes up the rest. The European Market Monitor on Energy Storage report forecasts 153GW/485GWh of additional installs by 2030, revising its previous forecast upwards due to heightened market activity, with Germany, Italy, and the UK hosting over 10GW each.

💡 Why It Matters

· Energy storage's overtaking of nuclear capacity underscores a significant shift in Europe's energy landscape, driven by rapid growth in electrochemical storage.
· Heightened market activity is revising forecasts upwards, with significant implications for the continent's energy transition.

Southeast Asia Has 5 Proposed Subsea Power Cable Projects By 2040 —…

Southeast Asia is poised to expand its electricity interconnector capacity by 2040, with 18 new and existing interconnectors needed to double the region's current 7.7 gigawatts. A new analysis from Ember highlights the importance of governance arrangements in ensuring the successful implementation of these projects. The report identifies three key gaps: regional planning, cost allocation, and coordination across maritime authorities, emphasizing the need for stronger regional planning, structured approaches to cost allocation, and greater coordination.

💡 The success of Southeast Asia's cross-border electricity ambitions hinges on the development of robust governance frameworks, which will determine the region's ability to strengthen energy security, improve access to diverse energy resources, and accelerate the transition to low-carbon growth.

Multi-day energy storage startup Ore Energy signs 1GWh iron-air battery deal with…

Energy storage startup Ore Energy has signed a deal with Dutch utility Budget Thuis to deploy up to 1,000MWh of multi-day-duration iron-air batteries. The 400MWh first phase is set to be delivered in 2028. Ore Energy's battery technology is based on iron, water, and air, and is configurable for discharge durations of 24 hours to 100 hours. This technology is designed to store wind energy over multiple days and dispatch it when needed, addressing the issue of curtailed renewable energy in Europe.

💡 The success of iron-air battery technology could be a game-changer for European grids, enabling them to store clean electricity when it's abundant and deliver it when it's most valuable. By reducing reliance on fossil fuels, utilities can provide customers with cleaner and more predictable electricity over time, ultimately reducing exposure to volatile fossil fuel prices.

Sunshine & Heat Pumps — How Greece Does Net Zero

Greece is embracing net zero technologies, particularly heat pumps and solar energy, to achieve a resilient and renewable future. The country's mild climate makes heat pumps an ideal choice for space conditioning, and they are widely used for cooling. Solar energy is harnessed through photovoltaic panels, solar water heating, and clothes drying, reducing reliance on fossil fuels. Greece has seen significant growth in solar power, with 17% of its electricity coming from solar in 2025. The use of solar water heating is especially prevalent, with 35% of homes having a solar water heater, providing essentially free fuel to heat water.

💡 Greece's approach to net zero technologies offers a unique model for other countries with similar climates. The widespread adoption of solar water heating, in particular, highlights its potential as a cost-effective and efficient solution for reducing energy consumption.

US President Donald Trump Makes Surprise Move Into Algae Biofuel

US President Donald Trump has made a surprise move into algae biofuel by transforming the Reflecting Pool in Washington, DC, into a breeding ground for green algae. This move supports the domestic algae biofuel industry, which is a key part of the "American Energy Dominance" policy. Algae biofuel has the potential to replace conventional crops and produce 10-100 times more fuel per acre. Companies like BRK Technology and Mazda are working on commercializing algae biofuel, with applications in heavy equipment and sports cars. The industry still faces challenges, but recent breakthroughs and investments suggest a promising future. Trump's move highlights the potential of algae biofuel as a sustainable energy source.

💡 Algae biofuel operations can achieve carbon negativity by absorbing CO₂ and recovering exhaust gases, making them a potentially game-changing technology in the fight against climate change. The US government's support for algae biofuel could also drive innovation and investment in the industry.

FERC Mandates Fast-Track Data Center Grid Access, Shielding Ratepayers from Costs

Federal regulators have issued orders to six major US grid operators to eliminate bottlenecks preventing AI data centers from connecting to the power grid, with developers bearing the connection costs. The orders, approved by the Federal Energy Regulatory Commission, cover grid operators serving 200 million Americans and aim to integrate large energy loads into the bulk electric grid while protecting consumers. The rules require grid operators to submit reliability reports and reform pricing structures within 60 days. This move addresses AI power demand as a national infrastructure crisis requiring federal coordination, shielding ratepayers from costs.

💡 By shielding ratepayers from AI infrastructure costs, FERC's orders protect household electricity customers from shouldering the financial burden of data center connections. FERC's move sets a standard for responsibly integrating large energy loads into the grid.
