Two Wells Drilled in Utah for Access to Hydrogen Storage Caverns

Caverns underground must be dedicated to specific gases under pressure and monitored for leakage

WSP Completes Drilling Two Wells for Utah Hydrogen Hub ~ Designed for Curtailed Renewable Energy Use

From an Article in Alternative Energy Magazine, June 6, 2023

SALT LAKE CITY — WSP USA, a leading engineering, environment, and professional services consultancy, has successfully completed drilling operation and mechanical integrity tests for two new cavern wells for the Advanced Clean Energy Storage (ACES) I project in Utah — part of the first phase for the ACES Delta hydrogen hub.

The Advanced Clean Energy Storage I project will convert renewable energy into green hydrogen that can be stored in utility-scale solution mined domal salt caverns. The ACES Delta hydrogen hub controls the only known “Gulf Coast”-style domal-quality salt formation in the western U.S., which contains five existing salt caverns already being used for storing liquid fuels.

Advanced Clean Energy Storage I is a wholly owned subsidiary of ACES Delta, LLC. ACES Delta is a joint venture between Magnum Development and Mitsubishi Power Americas.

WSP was contracted for the designing, drilling and completion of both cavern wells. Beside the drilling operation, WSP was responsible for designing procuring and managing the construction process of the project’s solution mining surface facility to provide water and power to the well sites and will manage the solution mining process until final completion of both caverns.

“Hydrogen underground storage is a key component of the hydrogen economy, which is critical in the effort to decarbonize U.S. power generation,” said Scyller Borglum, PhD, underground storage leader for WSP USA. “These underground salt dome caverns will provide a huge reservoir of renewable fuel for power generation, supporting levels of utility scale renewable energy storage that have not been previously possible.”

The drilling operation for each cavern well was completed ahead of schedule, and both cavern wells have successfully passed the mechanical integrity test designated to ensure well integrity prior to the start of the solution mining process.

Upon completion of the solution mining process, the total cavern volume of 9MM barrels-equivalent will be able to store around 300 gigawatt hours of clean and reliable energy in the form of hydrogen.

These will be the fourth and fifth hydrogen-compatible caverns in the U.S., and the salt cavern storage capacity will make it possible to store excess renewable energy produced in the spring when energy demand is low and use it to generate energy in the summer when demand is high.

WASHINGTON — Methane emissions from oil and gas drilling are under scrutiny as the Internal Revenue Service weighs how to assess the climate impact of clean hydrogen made from natural gas.

The numerous clean hydrogen projects under development along the Gulf Coast await a critical decision by the Biden administration on how to count the burgeoning industry’s greenhouse gas emissions.

The Internal Revenue Service is in the midst of deciding how companies qualify for a tax credit included in last year’s Inflation Reduction Act that could potentially be worth tens of billions of dollars in the years ahead. Environmentalists and some technology firms are pushing officials to consider not just how much carbon dioxide facilities are capturing and storing underground but emissions from the natural gas they use to make so-called blue hydrogen.
