A lawsuit has been filed by victims injured when an HVAC system fell into a pool at Gaylord Rockies Resort in Aurora, Colorado, on May 6, 2023. Aurora Fire Rescue said six people were injured when a large portion of steel ductwork collapsed onto the pool below that had 50 to 100 people in it. The lawsuit is against Gaylord Rockies Resort as well as 11 other defendants and claims that at the time of the collapse, the ductwork improperly contained a significant amount of water, showed a significant amount of rust corrosion on the internal surface and that the cable suspension system was grossly insufficient to support the weight of the ductwork. Read more
Natural gas producers are planning for a significant spike in demand over the next decade, as artificial intelligence drives a surge in electricity consumption that renewables may struggle to meet alone. According to a Wells Fargo analysis, electricity demand is forecast to grow as much as 20% by 2030. Power companies are moving to quickly secure energy as the rise of AI coincides with the expansion of domestic semiconductor and battery manufacturing and the electrification of the nation’s vehicle fleet. Read more

Researchers from Toronto Metropolitan University have proposed to combine hydrogen fuel cell systems with rooftop photovoltaic (PV) generation in building applications. They tested the configuration of the hybrid system at the BeTOP laboratory, located at the university's campus in Toronto, to gain insights into the potential application of hydrogen as a seasonal storage strategy in buildings. The proposed system includes PV panels, an alkaline electrolyzer, a compressor, a gaseous hydrogen storage unit, a fuel cell system, inverters and a control system regulating energy distribution within the system.

The European Investment Bank (EIB) is providing a loan of close to €45 million ($49 million USD) for an innovative closed loop geothermal heating project by Canada-based Eavor in the German state of Bavaria; the project is also being supported by a €91.6 million ($99 million USD) EU Innovation Fund grant. In contrast to conventional geothermal heating, the technology used in this project does not capture heat from subsurface water or steam reservoirs, and instead drills deeply into the earth and harvests heat directly from underground rocks. Read more
