Rice University professor and nanoscience pioneer Naomi Halas has received the 2025 Benjamin Franklin Medal in Chemistry.

In addition to her role at Rice, Halas is co-founder and technical advisor of Syzygy Plasmonics, a Houston startup that relies on light instead of combustion as an energy source. This enables efficient, sustainable transformation of low-carbon ammonia into hydrogen when powered by renewable electricity.

Halas earned the Franklin Medal “for the creation and development of nanoshells — metal-coated nanoscale particles that can capture light energy — for use in many biomedical and chemical applications,” according to a release from Rice.

Halas’ work has pioneered insights into how light and matter interact at small scales, according to Rice. She joined Rice in 1989 to support the late Richard Smalley’s advancements in nanoscale science and technology.

“A lot of people were talking about nano like it was something completely new,” Halas said in the release. “But I realized it was really just chemistry viewed in a different way, and that really got me thinking about how I can combine the worlds of laser science and nanoscience.”

That shift in perspective led to the development of nanoparticles that spawned innovations in fields such as cancer therapy, water purification, and renewable energy.

“Naomi’s contributions to nanoscience have not only expanded the boundaries of our understanding but also transformed real-world applications in medicine, energy and beyond,” Rice President Reginald DesRoches added. “Her pioneering work on nanoshells exemplifies the spirit of innovation that defines Rice.”

One of Halas’ projects led to the founding of Syzygy, which develops light-driven, all-electric chemical reactors for inexpensive, sustainable production of hydrogen fuel. The company was named to was named to Fast Company's energy innovation list last year.

Halas is the first Rice faculty member to be elected to both the National Academy of Sciences and the National Academy of Engineering for research carried out at the university. She also has been elected to the National Academy of Inventors, the American Academy of Arts and Sciences, and the Royal Danish Academy of Science and Letters. Halas holds 30 patents in the fields of medicine, chemistry, physics and engineering.

The Franklin Medal is awarded by the Franklin Institute of Philadelphia. Many scientists who have received the award have gone on to win Nobel prizes.

As a recipient of the Franklin honor, Halas will receive a $10,000 honorarium and a 14-karat gold medal during an award ceremony May 1 in Philadelphia.

2 Houston cleantech companies rank on most innovative energy companies lists

getting recognized

A pair of Houston energy startups have been named among the 10 most innovative energy companies for 2024.

Fast Company magazine just placed Fervo Energy and Syzygy Plasmonics on its energy innovation list. In all, 606 companies and organizations across a variety of industries were recognized for “reshaping industries and culture.”

Fervo produces carbon-free geothermal energy. Its existing geothermal project is in Nevada, and it’s building a geothermal project in Utah. The company recently raised $244 million.

“Solar and wind are cheap, but they don’t provide the kind of always-on dispatchable electricity that hydropower, hydrogen, and nuclear do; even at current high prices, enhanced geothermal is still cheaper than those other sources,” Fast Company notes.

The Fast Company accolade comes shortly after Time and Statista named Fervo one of the top greentech companies for 2024.

By relying on light rather than combustion to generate chemical reactions, Syzygy is taking on the use of fossil fuels in the chemical industry, Fast Company points out. Fossil fuels account for about 18 percent of the world’s industrial CO2 emissions.

Fast Company outlines some of Syzygy’s accomplishments in 2023:

  • Gained an undisclosed amount of funding from Mitsubishi Heavy Industries.
  • Completed its Pearland manufacturing facility.
  • Wrapped up 1,000 cumulative hours of testing on its ammonia-splitting reactor cell, capable of producing 200 kilograms of hydrogen per day.

Shell partners with UK-based co. for hydrogen electrolyzer pilot

ultra-efficient electrolyzer

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.
