Sugar Land-based advanced tech company Yokogawa Corporation of America, in collaboration with eight research institutions, has been awarded a $7.8 million grant from the Defense Advanced Research Projects Agency (DARPA) to develop and test a biologically fueled energy system.

The system known as Persistent Oceanographic Device Power, or PODPower, shows a pioneering advancement in microbial fuel cells (MFCs), a technology that aims to redefine how energy is harvested from oceans.

“Advancements in this area will play a role in our future as we harness this knowledge to address GHG emissions, produce clean energy, and enhance waste treatment,” Amro Hassanein, co-principal investigator and technology strategist, said in a news release.

The grant funds the system's Phase 1 development and deployment, and research is scheduled to continue through the summer of 2026. The company says the project has potential applications in climate monitoring, marine research, national security and clean energy generation.

The initiative will attempt to develop an MFC capable of generating up to 10 watts of continuous power for oceanic research and sensing devices through the use of microorganisms found in ocean water and specific bacteria samples.

“MFCs can process a variety of organic substrates including wastewater, agricultural residues, industrial byproducts, and marine biomass, demonstrating their versatility in applications such as on-site power generation bioremediation and biosensing,” Hassanein said in the news release.

As the only private company in the project, Yokogawa will lead the technical aspect to optimize the MFC technology through precision monitoring, data acquisition and machine learning algorithms.

The project team also includes collaborators from:

  • University of Maryland
  • Harvard University
  • Battelle
  • George Washington University
  • The Institute of Marine and Environmental Technology at the University of Maryland
  • Baltimore County
  • James Madison University
  • Johns Hopkins University
  • The University of Delaware.

Yokogawa believes that the system could power ocean sensing devices that provide key information for monitoring climate change, maintaining national security and understanding marine environments. The project plans to integrate bio-inspired organic matter collection systems, advanced fermentation processes and novel electrode designs.

Yokogawa Corporation of America is an affiliate of Tokyo-based manufacturing company Yokogawa. It moved its headquarters to Sugar Land in 2009.

A View From HETI

Solar barely eclipsed coal to become the third biggest source of energy generated for the Electric Reliability Council of Texas (ERCOT) in 2025, according to new data.

In 2024, solar represented 10 percent of energy supplied to the ERCOT electric grid. Last year, that number climbed to 14 percent. During the same period, coal’s share remained at 13 percent.

From the largest to smallest share, here’s the breakdown of other ERCOT energy sources in 2025 compared with 2024:

  • Combined-cycle gas: 33 percent, down from 35 percent in 2024
  • Wind: 23 percent, down from 24 percent in 2024
  • Natural gas: 8 percent, down from 9 percent in 2024
  • Nuclear: 8 percent, unchanged from 2024
  • Other sources: 1 percent, unchanged from 2024

Combined, solar and wind accounted for 37 percent of ERCOT energy sources.

Looking ahead, solar promises to reign as the star of the ERCOT show:

  • An ERCOT report released in December 2024 said solar is on track to continue outpacing other energy sources in terms of growth of installed generating capacity, followed by battery energy storage.
  • In December, ERCOT reported that more than 11,100 megawatts of new generating capacity had been added to its grid since the previous winter. One megawatt of electricity serves about 250 homes in peak-demand periods. Battery energy storage made up 47 percent of the new capacity, with solar in second place at 40 percent.

The mix of ERCOT’s energy is critical to Texas’ growing need for electricity, as ERCOT manages about 90 percent of the electric load for the state, including the Houston metro area. Data centers, AI and population growth are driving heightened demand for electricity.

In the first nine months of 2025, Texas added a nation-leading 7.4 gigawatts of solar capacity, according to a report from data and analytics firm Wood Mackenzie and the Solar Energy Industries Association.

“Remarkable growth in Texas, Indiana, Utah and other states ... shows just how decisively the market is moving toward solar,” says Abigail Ross Hopper, president and CEO of the solar association.
