Maximizing the Value of Your Molecule: A Game-Changing Approach to Data Center Power

Mark Feasel

March 11, 2025

In today’s rapidly evolving energy landscape, the concept of maximizing the value of a molecule is more than just an industry buzzword — it’s a critical strategy for super-charged data centers that need electricity to provide the artificial intelligence and high-end cloud computing that is in demand.

As this evolution is happening, we’re quickly learning that by leveraging every aspect of a molecule’s energy potential, we can unlock new opportunities for power generation, grid reliability, speed-to-market capabilities and cleaner emissions. 

That’s why we’re excited about a new collaboration with Diversified Energy Co. PLC (DEC) and TESIAC aimed at taking natural gas molecules from coal mine methane in Appalachia and turning it into as much as 360 MW of electricity that will, in turn, power the data centers and turn into megabytes. 

This unique approach – which combines the old world of fossil fuels with the new world of onsite distributed power generation -- recognizes two fundamental realities of the emerging order in energy: data centers need capacity, and they need it now.

There are a lot of ways to generate electricity for data centers – gas engines and turbines, fuel cells, solar and wind and even small nuclear reactors. Not everyone agrees on what the right one is, and that’s to be expected given the different needs of each customer and the variety of dynamics in the marketplace. The truth is there is no one-size-fits-all approach. 

But the one inarguable need is capacity. There is a digital arms race afoot when it comes to AI and cloud computing, and if data centers are going to boost their processing capability to the levels demanded, they will need more power. And we think speed is going to win. Generative AI requires constant training. If you aren’t training your AI systems now, you risk losing down the road. That requires massive amounts of electricity, and that is straining the grid. 

We believe partnering with DEC and TESIAC will help address this challenge of time to power head-on. For new projects, it will work like this. DEC will take the captured methane from coal mines that would ordinarily be vented or flared into the atmosphere and pipe it to fuel cells produced by FuelCell Energy. These fuel cells will form the cornerstone of a highly reliable and efficient microgrid which will meet the power and cooling needs of a data center without the emissions associated with conventional power generation such as gas turbines. TESIAC will help find the necessary financing and infrastructure development that will target faster deployment. 

And it can all be operating within two years.

Another way in which this collaboration will maximize the value of molecules is through the generation of Alternative Energy Credits which will help Pennsylvania utilities meet their environmental requirements when a fuel cell creates power from coal mine methane. 

Nobody knows for sure how the molecule-to-megabytes transition is going to fully shake out. Industry and policy assumptions from just 18 months ago now seem hopelessly outdated. But one thing we can predict with some certainty is that energy solutions will be increasingly fragmented and localized. That’s what makes our collaboration with DEC and TESIAC so important.

Providing the land and the securitized gas and the capacity to turn that into power may just be the key to meeting the demands of the moment.
