Google and Energy Dome Advance Multi-Continent Energy Storage Buildout with First Bilateral Project in Ireland

DUBLIN & MILAN--(BUSINESS WIRE)--Jun 23, 2026--

Today Energy Dome, a leading long-duration energy storage technology developer, and Google announced their first bilateral commercial contract for a 23MW / 200MWh CO2 Battery project located in County Offaly, Ireland. The project is part of a long-term partnership the companies announced last year to deploy Energy Dome’s CO2 Battery technology at scale and advance Google’s ambition to expand access to affordable, secure and 24/7 clean energy for grids globally. This announcement is on the back of a 19 MW/200 MWh project in Arizona announced this month by Energy Dome, Google, and the local utility SRP.

This project will be developed, owned and operated by Energy Dome using its proprietary CO2 Battery technology. The technology works by using grid power to compress and store CO2, then, when power is needed, expanding the CO2 through a turbine to generate energy that is sent back to the grid.

Strengthening grid reliability and sustainability in Ireland

The Irish government has identified long-duration energy storage as a key solution for ensuring security of electricity supply, reducing system costs, and enabling Ireland’s ambitious policy framework to reach 80% renewable electricity by 2030.

Through this commercial project, Google and Energy Dome aim to establish a blueprint for how long-duration energy storage technology can contribute to an affordable, secure and clean electricity system in Ireland. By absorbing surplus energy during periods of oversupply and dispatching firm power during periods of system stress, Energy Dome’s CO2 Battery can enable smart, cost-effective utilization of the grid’s renewable energy resources to balance the system while alleviating local grid congestion bottlenecks.

Located in County Offaly in the Irish Midlands near the town of Rhode, the site is strategically located on a critical node of the Irish electric grid, with high-voltage lines serving the Greater Dublin metropolitan area. Expanding energy resources in this area of the country is essential to greater economic growth in Irish demand centers.

Developed in concert with Lumcloon Energy, a leading local developer based in the Midlands, Energy Dome’s project creates jobs and long-term community benefits from deploying its cutting-edge technology. The project is sited on a former peat-fired thermal power plant, and will provide a second life for this brownfield industrial land by repurposing it into an engine for the clean energy transition. Located near the Rhode Green Energy Park, the surrounding area has abundant energy resources, including solar and wind, which suffer from curtailment due to high congestion in the local grid. By storing energy for later dispatch, the project provides congestion relief and avoids the costly buildout of transmission lines, translating into greater affordability for all users on the grid.

Claudio Spadacini, Founder and CEO of Energy Dome, said: “We are proud to work with Google on a project that strengthens grid resilience and unlocks the path to 24/7 carbon-free energy in Ireland. This project is the first commercial bilateral deployment under the strategic partnership between our companies, which aims to develop CO2 Battery projects across Europe, North America and Asia-Pacific.”

Compared to most battery supply chains, which depend on lithium-ion and other critical minerals, Energy Dome’s CO2 Battery uses available and off-the-shelf components. The adoption of Energy Dome's proven technology in Ireland shows how dispatchable, long-duration energy storage can meet rising electricity demand while strengthening the country's energy security, resilience, and reliability.

“At Google, we are committed to catalyzing next-generation energy technologies to bolster grid resilience and introduce critical storage capacity to the system,” said Vanessa Hartley, Head of Google Ireland. “This milestone is a next step in our long-term partnership with Energy Dome, and will help scale their promising long-duration energy storage technology, charging ahead to an affordable, secure and clean energy future.”

The project has already secured land, planning consent, and grid connection. It has also been awarded a 10-year capacity contract by EirGrid, the State-owned transmission system operator, and is expected to come online in 2028. Energy Dome plans to develop a second 200 MWh unit at this site, establishing a long-duration energy storage hub in the Irish Midlands.

PARIS (AP) — Millions of people across France woke up drenched in sweat on Tuesday after another night of scorching heat, with most of the population exposed to extreme and exceptional temperatures.

Temperatures will remain exceptionally high around the clock as the national weather service, Meteo France, placed 54 departments under a red heat wave alert. That is about half of the country.

In a country without widespread air-conditioning, schools, trains and sporting events remain impacted, while some 20 drowning deaths have been reported since the weekend.

Human-caused climate change is tied to increasingly extreme weather, and U.N. climate agency projections say the next five years should shatter more heat records.

“Sunshine continues to dominate across France, maintaining oppressive and exhausting heat throughout the country,” Meteo France said. Extreme conditions are expected to last at least until the end of the week, with daytime highs above 40 degrees Celsius (104 degrees Fahrenheit) in many towns.

“Further record-breaking temperatures are expected, including some that could surpass all previous records, regardless of the time of year,” Meteo France said.

The heat wave is exceptionally intense, coming very early in the summer, “but with a still uncertain duration,” the weather service said. It has already been compared to the August 2003 heat wave, when the highest temperatures in over half a century caused an estimated 15,000 deaths, many of them among older people in apartments and retirement homes without air conditioning.

France introduced a heat watch warning system after that heat wave.

Europe is the world’s fastest-warming continent, with temperatures increasing twice as fast as the global average since the 1980s, according to the European Union’s Copernicus Climate Change Service.

Over the last four years, more than 200,000 people across Europe died from heat-related causes, and most of those deaths were preventable, the World Health Organization’s Europe office said this month. The above-average temperatures can cause heat exhaustion and life-threatening heat stroke.

Across the English Channel, the Met Office issued a red extreme heat warning for Wednesday and Thursday, with forecasts suggesting June’s all-time daily temperature record could be broken.

Temperatures of around 37°C (98.6 F) are expected in southern England, with up to 35°C (95 F) in southeast Wales. The peak of the heatwave is now forecast for Wednesday and Thursday, when highs could reach at least 39°C (102.2 F). Conditions are expected to ease by Friday, the weather agency said.

The EU monitoring agency found that in Europe and globally, 2024 was the hottest year on record and the continent experienced its second-highest number of “heat stress” days.

Scientists warn that climate change is exacerbating the frequency and intensity of heat and dryness, especially in southeastern Europe, making the region more vulnerable to health impacts and wildfires.
