Catching AI data center heat to cut energy costs and benefit communities

By District Energy posted 2 days ago

West Virginia Watch Summary Artificial intelligence data centers are arriving faster in Appalachia than the policies to manage them. In March, West Virginia Gov. Patrick Morrisey announced that Google would build an AI data center in Putnam County. At the same time, public skepticism is rising, with four in 10 Americans saying that data centers are mostly bad for the environment and home energy costs. This tension frames a real issue. As a March Brookings report on AI data centers in rural communities put it, “The central question is not whether data centers are ‘good’ or ‘bad,’ but how benefits and risks get allocated and what forms of governance, ...

Denver Looks to Sewers, Geothermal Wells for Downtown Energy Network

By District Energy posted 2 days ago
Be the first person to recommend this.
ENR Summary Denver officials are exploring an infrastructure strategy that could offer a blueprint for retrofitting dense downtowns. The city is advancing a pilot project that will use geothermal wells and heat recovered from wastewater to create a shared ambient-loop network between two downtown buildings and a sidewalk snowmelt system. It plans to later expand to as many as 10 municipal buildings, with an estimated cost between approximately $280 million and $320 million over the next decade. City officials plan to reuse portions of Denver's existing district infrastructure where possible to build the network, rather than build from scratch. Continue ...

As geothermal networks grow, so does the call for a new utility model

By District Energy posted 2 days ago
Be the first person to recommend this.
Canary Media Summary When a neighborhood-scale geothermal network came online in Framingham, Massachusetts, two years ago, it was hailed as groundbreaking. The first-of-its-kind system, owned by the state’s largest utility, Eversource, delivers warm and cool air to some 140 customers through pipes much like the ones that used to carry natural gas to those homes and businesses. But instead of burning fossil fuels to generate warmth, the network draws on emissions-free thermal energy stored in the ground beneath the community. To deliver cool air, the system returns the heat back into the earth. Supporters say this approach to climate-friendly ...

Storing renewables with compressed air in urban heating pipeline

By District Energy posted 3 days ago
Be the first person to recommend this.
pv magazine Summary Researchers in China have proposed a novel method for storing surplus renewable energy by converting it into compressed air and integrating it into urban district heating pipelines. In this concept, existing infrastructure used to circulate hot water or steam for building heating is repurposed as an energy storage medium. The system operates on an adiabatic principle, in which the heat generated during air compression is captured and reused rather than dissipated, improving overall efficiency.

Let's Data Science Summary Several European projects are redirecting waste heat from large data centers into local heating systems. Per Google, the Hamina data center will supply 80% of the annual heat demand for a local district, according to Google's corporate blog. Microsoft reports a Høje-Taastrup, Denmark data center under construction will produce enough surplus heat to warm about 6,000 homes, per a Microsoft local blog post. SlashGear reports Microsoft has a partnership with Fortum in Finland targeting heat delivery to 250,000 homes and businesses.

Be the first person to recommend this.
Irish Independent Summary The Government has been urged to “move rapidly” to make sure the 300,000 new homes planned for Ireland by 2030 can avail of district heating. The Irish District Energy Association (IrDEA) has urged the Government to increase supports for district heating in this year’s Budget. More than one third of all energy used in the country is used to generate heat, however around 90pc of this is still generated using fossil fuels, with 80pc of these imported from outside the country. District heating uses energy from sources within Ireland, such as renewable energy or waste heat from data centres, to distribute heat to homes and businesses. ...

Forbes Summary Inside a pharmaceutical plant, heat is everywhere—and until recently, almost nobody was paying attention to it. Steam rising from boilers. High-temperature reactions turn raw inputs into finished drugs. Buildings and manufacturing lines are kept at precise temperatures around the clock. For decades, the fuel behind it all was natural gas, cheap enough that nobody questioned it and complex enough that nobody wanted to touch it Now, AstraZeneca , working with the supply chain platform Secaro and the sustainability consultancy ERM, is launching a Clean Heat Program designed to do something that's proven surprisingly hard: systematically ...

Networked Geothermal Takes Off for Heating and Cooling, But Gas Heating Still Dominates

Be the first person to recommend this.
The Energy Mix Summary While networked geothermal systems—which heat and cool several buildings using shared underground infrastructure and electric heat pumps—are gaining some traction in Canada, their reach has been limited by planning and regulatory systems that provide a continuing foothold for legacy gas heating systems. Unlike traditional ground-source heat pumps, which serve a single building with dedicated boreholes, networked geothermal shares the underground infrastructure across multiple buildings. Europe boasts about 400 networked geothermal projects , with more on the way. Continue Reading #News #GeothermalandGeo-Exchange ...

Denver has a plan to heat and cool buildings without fossil fuels. It involves … sewage?

By District Energy posted 9 days ago
Be the first person to recommend this.
NPR Summary Like in many American cities, Denver's largest source of climate pollution is its buildings. Powering, heating and cooling the city's skyscrapers takes a lot of fossil fuels. Now, the city is trying a greener solution. It plans to heat and cool a cluster of large downtown buildings using a combination of water, the heat of the Earth — and sewage. Denver will pilot what's called a thermal energy network. Similar networks already exist on campuses and in some cities around the world. If it works here, it could set an example for how to decarbonize a dense, downtown core in the United States. Most people don't think of sewage as a ...

hoodline Summary Denver is gearing up to warm and cool chunks of its downtown with a first-of-its-kind hybrid thermal network that links deep geothermal wells, a closed loop of circulating water and heat skimmed straight from city sewers. City officials say the system could eventually serve office towers, museums and even keep sidewalks clear of ice, all without burning fossil fuels. They expect the plan to move from paper to an on-the-ground pilot within the next two years. Warm wastewater flowing through large interceptor pipes carries usable thermal energy that can be captured with plate-and-frame heat exchangers, then boosted by heat pumps into building ...

London Loves Business Summary Grant funding, refinancing pressure and carbon expectations are turning heat networks into a commercial property issue for London landlords. London is the UK’s most concentrated heat-network market, with district heating schemes across the Olympic Park, Battersea, Greenwich Peninsula, King’s Cross, Nine Elms, Stratford and Brent Cross. It is also home to the country’s largest concentration of commercial property, facing tighter decarbonisation scrutiny. In 2026, those facts are converging into a boardroom question for owners, asset managers, developers and FDs: how long can heat decarbonisation be delayed before ...
