Minnesota housing project to draw energy from water stored deep underground, 45 years on from city’s initial research

Nearly half a century ago, the US Department of Energy launched a clean energy experiment beneath the University of Minnesota with a simple goal: storing hot water for months at a time in an aquifer more than 100 metres below ground.

The idea of the seasonal thermal energy storage was to tuck away excess heat produced in summer, then use it in the winter to warm buildings.

Projects in development expected to grow global capacity by nearly 50% amid growing concern over impact on planet

The US is leading a huge global surge in new gas-fired power generation that will cause a major leap in planet-heating emissions, with this record boom driven by the expansion of energy-hungry datacenters to service artificial intelligence, according to a new forecast.

This year is set to shatter the annual record for new gas power additions around the world, with projects in development expected to grow existing global gas capacity by nearly 50%, a report by Global Energy Monitor (GEM) found.
