A Houston-headquartered hardtech company that's working on technology to enable hypersonic travel has announced a partnership with NASA to test its tech.

Venus Aerospace has partnered with NASA’s Marshall Space Flight Center in Huntsville, Alabama, on what is reportedly the longest sustained tests of a rotating detonation rocket engine, also known as an RDRE.

“Venus believes strongly in the performance step-change that RDREs bring for both hypersonic and space applications. The partnership with NASA has been key in maturing this new technology.” Andrew Duggleby, CTO and co-founder of Venus Aerospace, says in a news release.

The company's engine injector, which used regeneratively-cooled RDRE architecture, was tested in a "flight-like manner," according to the company. The technology operated successfully for 4 minutes of hotfire testing — a significant improvement, as engine tests of this type last for only 1 to 2 seconds, according to Venus.

"This long-duration hotfire means RDRE’s have retired a major risk area and are able to move into the few remaining steps before a flight demonstration," reads the press release from Venus.

As Venus continues to develop its technology for research, defense, and commercial missions, it will continue to work with NASA, which is also looking into RDRE technology for lunar and martian landers, in-space operations and logistics, and other deep space missions, per the release, because RDREs are more compact, efficient, and versatile than traditional rocket engines.

"Venus has entered into a second-year contract with NASA to provide engine parts for research and development of NASA’s RDRE," the news release continues. "In year two, NASA, with Venus’s support, will test different propellant combinations on hardware, to operate at even higher thrust levels and to demonstrate efficiency gains promised by the detonation engine."

Last summer, Venus added a new investor to its cap table. Andrew Duggleby founded Venus Aerospace with his wife and CEO Sarah "Sassie" Duggleby in 2020, before relocating to the Houston Spaceport in 2021. Last year, Venus raised a $20 million series A round.

Kanin Energy, a member of the Greentown Labs climatech and energy incubator in Houston, recently raised as much as $100 million in capital to grow its energy-as-a-service platform.

S2G Investments led a round of up to $50 million, and the Canada Growth Fund chipped in an additional $50 million. The money will primarily support Kanin’s development and operation of waste-heat-to-power projects.

Kanin—founded in 2020 in Calgary, Alberta, Canada—builds and runs onsite power assets for large-scale energy users. The startup says its energy-as-a-service offering lowers power costs, boosts power reliability and decreases emissions.

The company operates a waste-heat-to-power project at Ohio’s University of Dayton. The project supplies zero-emission electricity.

Kanin has a pipeline of projects totaling about 50 megawatts of capacity. This includes a waste-heat-to-power plant at the Phillips 66 Mewbourn gas-processing plant near Greeley, Colorado.

“Kanin was built on the belief that industrial facilities already hold the solution to their own energy challenges, they just need the right partner to execute,” Janice Tran, CEO of Kanin, who is based in Houston, said in a release. “At a time when power costs continue to rise, [our] solutions are an important tool for our industrial customers to manage their costs, operations, and emissions.”

Marisa Sweeney, principal at S2G, says waste heat is a largely underused resource for lowering power costs, alleviating grid congestion and improving power reliability.

The waste-heat-to-power process captures thermal energy from industrial activities and converts it to electricity. This happens without using extra fuel or generating more emissions.

Kanin says up to 58 percent of energy consumed by industrial processes is lost as waste heat. This heat winds up in the atmosphere at thousands of facilities in North America, including oil-and-gas operations, cement plants, and steel mills, the startup says.

Kanin was founded in 2020 in Calgary, Alberta, Canada. It opened offices at Greentown Labs Houston in July 2022.
