Startup's Hydrogen Breakthrough May Give New Life to Coal Plants

A small Australian research lab tucked away in a coastal town, 70 kilometers (43 miles) north of Sydney, says it has developed a patented technology using a catalyst that can turn hydrogen and oxygen into superheated steam capable of driving a power-station turbine.

"Our model works on heat from hydrogen," said Andrew Horvath, chairman of Star Scientific Ltd. The system is "plug-and-play," he said at the company's research facility in the town of Berkeley Vale. "It is quickly deployable, it's a lot smarter to work with."

Wearing high-vis jackets and safety goggles, Chief Technology Officer Steve Heaton and another member of the team demonstrated an experimental model that looks like a French coffee press. Bottled hydrogen and oxygen are fed into a glass cylinder containing the secret catalyst, which quickly turns orange as it heats up to around 700 degrees Celsius (1,292 Fahrenheit). If the technology can scale up, it could ultimately allow power plant operators that burn coal to retrofit generators to run on green hydrogen without having to construct a completely new plant.

"We think there are a lot of opportunities in existing steam turbines that have some longevity," said Horvath, citing the example of Japan where 70% of its turbines still have 40 years of life left. "Why would you throw them away? They're already connected to the grid."

In January 2021, the company signed an agreement with the Philippines government to study retro-fitting coal-fired power plants in the Southeast Asian nation.

Star Scientific's system differs from traditional ways of generating heat from hydrogen, such as through combustion or in fuel cells, according to Horvath, who as a child would spend weekends in the lab of his nuclear physicist father, experimenting with the gas.  "We don't burn hydrogen and that's going to be the real key that we've been driving and people are taking notice of," he said.

Staff are fielding dozens of emails a day from prospective clients, he said, and the company is in talks with water-treatment companies, brewers, dairy firms and abattoirs about using the system. "There's so much demand, the market's coming to us," he said.

A pilot project to test the system at a factory run by a local unit of Mars Inc. is awaiting regulatory approval, which Horvath expects will come in 2023.

The technology "offers enormous potential across the food manufacturing industry," said Bill Heague, general manager of Mars Food Australia. "Thermal energy is crucial to the business of cooking food and this technology has the capability to create limitless heat without any combustion and zero emissions."

Star Scientific was started 25 years ago to commercialize nuclear fusion work done by Horvath's father Stephen that used heavy hydrogen containing unstable sub-atomic particles called muons. During the research, the team unexpectedly discovered a way to convert hydrogen into heat without burning it, a breakthrough patented as the Hydrogen Energy Release Optimiser, or HERO.

"Star Scientific's technology can be scaled up and used for a variety of different applications either direct energy generation through a turbine or just thermal heating," said Scott Donne, a professor at the School of Environmental and Life Science in the University of Newcastle, near Star Scientific's lab. "Around where we are in Newcastle, there are four very large coal-fired power stations that basically use steam to actually drive their turbines. At the moment, it's done with coal-fired power but it could conceivably be done with hydrogen using the existing infrastructure."

Where the winds are blowing

"I think UK hydrogen production needs to be offshore."

Macquarie Group Ltd. is betting the North Sea's shallow waters and gusty winds are a boon for the renewable electricity needed to make green hydrogen.

Despite the dire environmental consequences, the world has never produced more plastic — some 500 million tons annually — and experts predict that to double by 2040. One reason is that plastic is cheap and useful. Another is the success of industry-led campaigns that say we can use it sustainably. A Bloomberg Green investigation finds that an initiative backed by Coca-Cola, Unilever and Danone to recycle the plastic waste in Ghana is better at deflecting blame and avoiding regulation than actually recycling.

  • One answer to Europe's energy crisis? More electric cars. EVs en masse are great for storing renewable electricity and sending it back to the grid.
     
  • Billionaire Mike Cannon-Brookes is urging Australia to act more on climate, even as the new government begins to strengthen emissions cuts.
     
  • US President Joe Biden's big goal of decarbonizing the nation's electricity system is clashing with a plan to prolong the life of some coal plants.
