Houston-based renewable energy company that focuses on clean energy storage closed its $10 million series B financing round and secured a major contract.

Quidnet Energy announced its latest round and the execution of a contract with the New York State Energy Development Authority. Bill Gates-backed Breakthrough Energy Ventures and Canada-based Evok Innovations, which both previously invested in the company, contributed to the round. The round also featured new investors Trafigura and The Jeremy and Hannelore Grantham Environmental Trust.

"Long-duration electricity storage is critical to the energy transition. It's exciting to see how Quidnet is bringing this viable long-duration solution to the market," says Mike Biddle, managing director at Evok Innovations, in a news release. "Because they are leveraging long understood geologic principles, we are confident that they can scale rapidly. We are pleased to support the Quidnet team through its next phase of commercial growth."

According to the release, the company will use the funds to grow its team and scale up its operations in order to be able to deliver commercial-scale projects across the country's electric grid.

"Integrating renewables and replacing retiring thermal generation require cost-effective long-duration electricity storage at an immense scale," says Quidnet Energy CEO Joe Zhou in the release. "While traditional pumped hydro has provided over 95 percent of the world's grid-scale storage, that approach faces significant siting and cost limitations going forward. Quidnet unlocks these constraints to fundamentally change the economics and deployment profile of long-duration storage."

Quidnet's deal with NYSEDA is a part of the organization's efforts to reduce the state's carbon footprint while also lowering the cost of traditional energy storage.

"Under Governor Cuomo's leadership, New York is investing in the technology research and development needed to advance a 21st electric grid that can support the State's growing influx of renewable energy," says Alicia Barton, president and CEO of NYSERDA, in the release. "Congratulations to Quidnet on this opportunity to develop and demonstrate the value that this innovative technology can bring to New York as we work to reduce greenhouse gas emissions and transition to a 100 percent clean electric grid."

Last month, the Rice Alliance for Technology and Entrepreneurship hosted its annual Energy Tech Venture Day online, and Quidnet was among the Houston energy companies to pitch virtually.

Houston team develops MyoStep soft skeleton for kids with cerebral palsy

health tech

A team from the NSF University of Houston Building Reliable Advances and Innovation in Neurotechnology (UH BRAIN) Center and TIRR Memorial Hermann has introduced the MyoStep soft exoskeleton for children with cerebral palsy, according to a news release from UH.

The soft skeleton aims to address motor impairments caused by cerebral palsy that impact children’s ability to participate in physical activities, self-care and academics.

“The MyoStep project represents a significant advancement in the field of pediatric mobility aids, particularly for children with cerebral palsy,” Jose Luis Contreras-Vidal, director of UH BRAIN and the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering, said in a news release.

The next-generation lightweight, soft exoskeleton was funded by the IEEE Electron Devices Society (EDS) Award.

The MyoStep is made to be lightweight and discreetly fit under clothes. It includes a wireless sensor network embedded inside the smart and flexible fabrics that is the backbone of the suit and collects and sends real-time data about the user’s movements It also includes safety features with temperature monitoring and emergency shut-off mechanisms.

“By integrating cutting-edge technologies such as artificial muscles, smart fabrics, and a comprehensive sensor network, MyoStep offers a promising solution to the challenges faced by existing exoskeletons,” Contreras-Vidal said in a news release.

Cerebral palsy is a neurological disorder that impacts motor skills. It occurs in one to four out of every 1,000 births worldwide.

“What makes the MyoStep project so compelling is that it’s not just about the technology: it’s about restoring confidence, function, and hope,” Dr. Gerard Francisco, a clinical partner on the technology, The Wulfe Family Chair of Physical Medicine and Rehabilitation at UTHealth Houston and medical officer at TIRR Memorial Hermann, said in a news release. “This kind of innovation has the potential to dramatically improve quality of life, helping children move through the world with greater ease and dignity.”
