Ohio

Overview

Ohio is the nation’s the fourth-largest electricity consumer. It ranks among the top 10 states in electricity generation. Natural gas has fueled the largest share of Ohio's in-state net generation since surpassing coal as the state’s largest power source in 2019. While wind and solar have grown significantly in recent years, the state’s renewable portfolio standard has been suspended and a new law empowers county government to reject, ban or restrict wind and solar projects in their localities. Ohio is part of the PJM Interconnection, which is taking steps to recognize the reliability benefits that storage projects can provide to a grid powered with renewable energy.

Solar

  • 150 MW of solar farms are currently operating in Ohio, according to the Ohio Power Siting Board (OPSB).
  • An additional 2,924 MW of solar have been approved for construction.
  • Another 4,405 MW of solar power have been proposed for development.

Wind

  • Ohio has more than 1,000 MW of installed wind generating capacity in operation, the OPSB reports.
  • Another 728 MW of wind generating capacity has been proposed.

Energy Storage

  • The US EIA reports that large-scale battery installation in Ohio totaled 33 MW of power capacity.

The Need for Storage

Ohio’s long-standing reliance on electricity powered by fossil fuels provides significant growth opportunities for alternative, carbon-free resources. Substantial development of solar photovoltaics and wind turbines is expected in Ohio. But those variable energy resources can only generate power when the wind blows and the sun shines. As a result, energy storage is needed to make their power available whenever it is needed. Long-duration energy storage is key to sustaining Ohio’s electric system reliability.

Quidnet is using fossil fuel industry expertise and experience to make long-duration energy storage a reality in Ohio and other parts of the nation. We are developing and deploying energy storage using the science of geomechanics and time-tested pumped-storage hydropower technology. Our system is modular, scalable, and terrain-independent, offering structural cost advantages, with lower per-megawatt installed costs than gas peaking plants and alternative storage systems. We’re reliable and ready, with equipment provided and serviced by mature suppliers from well-established industries.

A Robust Development Opportunity

Appalachian Basin

Geologic age: 380 million years

Quidnet uses the pressure found deep within the rock of Ohio as a natural resource that enables our innovative GPS technology. The level of this pressure is determined by the regional sedimentary conditions developed over millions of years of geological activity.

Roughly 480 million years ago during the Ordovician period, the tectonic plates comprising the modern-day continents of North America and Africa pushed into each other. The incredible forces from this convergence pushed up the Appalachian Mountains, a chain of highlands that stretch nearly 2,000 miles from the Canadian province of Newfoundland and Labrador to the U.S. state of Alabama.

Over the next 100 million years, through the Devonian period, sediment shed off from these new mountains accumulated in low-lying clay deposits. This accumulation continued to grow over millions of years until the buried clay hardened to become the sedimentary rock known as shale.

Shale is the most common seal for hydrocarbons (natural gas and petroleum), in part because of the ability of this rock to trap vast pockets of mineral wealth. This same characteristic – known as “impermeability” – makes it ideal for storing pressurized water without leaking. The thick sequence of shales that make up the Appalachian Basin stretch from parts of New York, as west as Ohio, and as south as Georgia.

The first oil well in Ohio was drilled in 1859. Existing drilling data from over a century of petroleum prospecting provides Quidnet with an abundance of data that helps our geologists identify target locations for the deployment of Quidnet’s GPS energy storage solution. The rock in each site location must have suitable subsurface conditions and contain no unwanted hydrocarbon content.

Through testing, Quidnet has verified that the storage pressure of the rock in the Appalachian Basin is substantial. To build a traditional pumped storage facility with equivalent water pressure through gravity alone, the water would need to be pumped into a reservoir over 1,800 feet up a cliff. Quidnet's GPS provides the energy generation capacity of pumped storage on a smaller footprint and independent of terrain.

Now, under the Biden Administration's leadership, we are making historic investments in our clean energy infrastructure through the American Jobs Plan. I have full confidence that Ohio is going to be a key piece in that puzzle.

Partnering with Federal Investors

The U.S. Department of Energy (DOE) is among the public and private investors in Quidnet Energy’s innovative energy storage system. Quidnet partnered with DOE’s Water Power Technology Office through its HydroWIRES Initiative to develop an innovative reversible injector-generator that will enable deployment of modular hydropower conversion in high-pressure pumped hydro applications such as Quidnet’s Geomechanical Pumped Storage (GPS) technology.

Quidnet is also working with Advanced Research Projects Agency–Energy (ARPA-E) through their Duration Addition to electricitY Storage (DAYS) program to develop the GPS resource in key power markets across the US by planning and executing exploratory wells to characterize, evaluate, and validate the geologic resource, including inactive oil and gas well sites .
