Power plants are engineered with precision down to the smallest detail, yet one critical variable is often considered too late in the process: water chemistry. When it’s considered early in design rather

Data centers are the backbone of the digital age, housing the servers and networking equipment that power everything from cloud computing to streaming services. As these facilities grow in size and complexity, so does the challenge of keeping them cool.

The U.S. Environmental Protection Agency (EPA) has moved to shift capital planning and permitting timelines for the nation’s remaining coal-fired power units, acting on two measures targeting wastewater discharge under the Clean Water Act, and separately, air-quality visibility programs and the Clean Air Act. On Sept. 29, the EPA issued a proposed rule and companion […]

Thermal power plants, nuclear and fossil-fueled, rely on cooling water intake structures (CWIS) to withdraw water for rejecting waste heat. The CWIS serves as a critical interface between engineered systems and the natural environment, making it vulnerable to various external factors such as biological growth, water chemistry changes, hydraulic forces, drifting debris, and meteorologic events. […]

Reverse osmosis (RO) is a vital water purification technology used in various applications such as boiler feedwater treatment, cooling water systems, and wastewater recycling. The feedwater for RO can

As electricity demand soars during summer heat waves, many power plants find themselves constrained by their ability to cool water efficiently for reuse. Innovative floating cooling technology is enabling

Citing a mounting compliance crunch in America’s coal-fired power sector, the U.S. Environmental Protection Agency (EPA) has finalized new rules extending key deadlines for coal ash cleanup and management, while floating the prospect of a further 12-month delay. The changes address calls from utilities, engineering contractors, and state regulators for more realistic timeframes to assess, […]

In drought-prone Southern California, Burbank Water and Power has implemented a groundbreaking stormwater capture and reuse system that saves more than eight million gallons of water annually. This

Our state-of-the-art lab aims to replicate and optimize real operating conditions so that you can maximize the hydroprocessing component of your facility. Learn how today.

Energy and water are like dance partners in a complex ballet, each intricately linked to the other. On the global stage, the greatest demand for water is for electric power generation, while the most energy-intensive sector is the extraction, treatment, and distribution of water.

Energy storage solutions group Quidnet Energy said the company has successfully completed demonstration and testing of its Geomechanical Energy Storage (GES) technology at a megawatt-hour (MWh) scale.

Through a cutting-edge heat exchange system, the Museum of Bavarian History in Regensburg, Germany, efficiently heats and cools its building, showcasing a promising solution for urban decarbonization and clean

Experienced boiler operators know that oxygen can cause localized, severe corrosion in steam boiler systems through a process called oxygen pitting. This occurs when dissolved oxygen in the water comes into

Power plant managers know that optimizing cooling water operations will improve efficiency. Using an integrated approach that combines advanced chemistry, digital technologies, such as deposit sensing, and

Brazilian independent power generator Epasa faced significant environmental and operational challenges with heavy fuel oil sludge. Through innovative engineering and problem-solving, the company developed a

While the effects of extreme summer weather are one thing, even regular summer weather can wreak havoc on steam and water analysis systems (SWAS) without adequate preparation. Summer sunshine and increased temperatures can bring higher heat loads and increased cycling rates that put even more stress on steam and water sampling and related equipment, greatly […]

The much-watched Advanced Clean Energy Storage Hub (ACES Delta)—a project shaping up to be the largest renewable hydrogen energy hub in the U.S.—has received its first shipment of large-scale hydrogen electrolyzers and gas separators.  The shipment, unveiled on Oct. 25, marks the first equipment delivery for the Delta, Utah, project’s integrated Hydaptive package. Hydaptive is […]
