Proposed Ohio data center power plants raise emissions and carbon capture concerns

An opinion piece in yourohionews.com warns that proposed methane-powered electric plants, intended to supply data centers across Ohio, could lead to a substantial increase in annual greenhouse gas emissions, potentially reaching 75 million tons if all 10 planned facilities operate at full capacity. The author characterizes carbon capture and sequestration (CCS) technology, which some tech companies and energy firms are exploring to offset these emissions, as an unproven "greenwashing" tactic.

This technology relies on toxic chemicals like ethylene oxide during capture and involves injecting high-pressure carbon dioxide into Class VI wells, a process for which Ohio's Department of Natural Resources reportedly lacks experience. The article highlights a specific development by Tenaska, which has announced plans for a Tri-State Energy Hub in Saline Township, Jefferson County, and has applied for 10 Class VI well permits in Harrison County. These wells would store supercritical carbon dioxide under residents' properties.

The author argues that for data centers and power companies, CCS presents a mutually beneficial scenario, allowing data centers to claim reduced climate impact while power plants gain tax credits. However, the piece contends that for taxpayers, it represents a "boondoggle" with inherent dangers and costs, urging residents and first responders to educate themselves on the hazards associated with collecting and injecting carbon dioxide.
