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.

Houston-based Quaise Energy is looking to raise $200 million to support the development of a 50-megawatt superhot geothermal plant in Oregon.

The company is seeking $100 million in Series B funding, plus an additional $100 million from grants, debt and project-level finance, a representative from the company tells Energy Capital. Axios first reported the news late last month.

Quaise specializes in terawatt-scale geothermal power. It is known for its millimeter-wave drilling technology, which was developed at MIT.

The company's Project Obsidian development in central Oregon will combine conventional drilling with its millimeter-wave technology. Quaise says the project, targeted to come online in 2030, could be the first commercial plant to operate in superhot rock, a more efficient and abundant resource, but one that requires more advanced and durable drilling technology.

Quaise says Obsidian would initially generate 50 megawatts of "always-on" power and would be designed to add 200 megawatts as additional wells are developed. A power-purchase deal has already been signed for the initial 50 megawatts with an undisclosed customer.

A representative from the company says Quaise would also use the funding to continue advancing its millimeter-wave technology and prepare it for commercialization.

Last year, the company drilled to a depth of about 330 feet using its millimeter-wave technology at its field site in Central Texas.

“Our progress this year has exceeded all expectations,” Carlos Araque, CEO and president of Quaise Energy, said at the time. “We’re drilling faster and deeper at this point than anyone believed possible, proving that millimeter-wave technology is the only tool capable of reaching the superhot rock needed for next-generation geothermal power. We are opening up a path to a new energy frontier.”

Canary Media reports that Quaise plans to drill to nearly 3,300 feet later this year and to deploy its millimeter-wave technology at its power plant in 2027.

Quaise raised $21 million in a Series A1 financing round in 2024 and a $52 million Series A in 2022. Major investors include Prelude Ventures, Safar Partners, Mitsubishi Corporation, Nabors Industries, TechEnergy and others.

Quaise was one of eight Houston-area companies to appear on Time magazine and Statista’s list of America’s Top GreenTech Companies of 2025.
