If there was a Houston innovation ecosystem playing card, Joanna Nathan would definitely have BINGO by now. From starting a startup while a student at Rice University and being an early hire of medical device company Saranas to leading investment at Johnson & Johnson's Center for Device Innovation, Nathan is headed back to the founder seat with Prana Thoracic, a new company planning to equip physicians with a better tool for lung cancer intervention.

"Unlike breast, prostate, and other types of cancers, we historically have not actively screened for lung cancer," Nathan says on this week's Houston Innovation Podcast. "Screening has only just begun in this world, and because of that, physicians still need the right tools to take early screening information and turn it into early intervention."

Last month, Nathan, who serves as CEO of the company, and Prana announced that Nucore Medical Inc., its wholly owned subsidiary, has been awarded a $3 million grant from CPRIT. Click here to read more and stream the podcast episode.

This probably isn't breaking news, but the world is on the midst of a water crisis. More than 2 million Americans don’t have access to clean drinking water, according to one study by the U.S. Water Alliance group.

To help close that water gap, international firm, Botanical Water Technologies, has plans to expand its presence in the United States with the Houston region being a strategic area to roll out the implementation of a patented water filtration technology. In addition, the group is launching a blockchain enabled trading platform with Fujitsu to help support the business.

“Water is finite,” says Houston-based James Rees, chief impact officer at BWT. “Due to global growth and climate conditions, we are going to have between 20 to 30 percent less water available to us by 2025. Communities are facing issues with water infrastructure. Some communities don't have water. This is where BWT plans to come in to help.” Click here to read more.Click here to read more.

Over the course of the summer, Aimee Gardner has been writing strategic columns for startups with hiring tips. Her articles have focused on scaling quickly, why not to just trust your gut when hiring, and attracting and retaining a diverse workforce.

Gardner's advice is especially keen since she herself is a startup founder — but also has a Master's degree in organizational psychology. For years, she's been advising both her clients at her company SurgWise Consulting, but also students at Baylor College of Medicine.

"If your startup has gotten to the point of being able to grow the team, it is clear that ample vision, strategy, and innovation has been dedicated to the mission up until this point. Hiring in the next round of team members is not a process that should undergo any less dedication," she writes in one of her articles. "Ensuring that those around you share your vision, goals, and have a complementary set of skills and attributes will be critical to ensure success in your company’s growth and achievements."

EDP Renewables, whose North American division is based in Houston, has launched the second module of its Energy Starter 2022 program.

EDP Renewables launched the first module in May; it dealt with the future of energy distribution. Applications for startups seeking to join the second module are being accepted until September 30. The second module focuses on innovations in renewable energy and green hydrogen.

Next year, the third and final modules will focus on decarbonization.

Companies selected for the second module will attend a bootcamp in Houston where they, in partnership with EDP Renewables experts, will develop their ideas and work on pilot projects. After the current four-phase edition of the program ends, startups will be able to test their innovations in the U.S., Brazil, Portugal, or Spain.

During the six editions of Energy Starter, the more than 150 participating startups have sealed over 80 deals, including equity investments and pilot projects. The most recent edition of Energy Starter attracted over 700 applicants.

Earlier this year, EDP Ventures, the venture capital arm of EDP Renewables North America’s parent company, pledged to double its investments in startups pursuing energy transition technology and services.

EDP Ventures says its VC commitment is climbing from 45 million euros (about $45 million) already invested in the past decade to a total of 100 million euros by 2025. EDP Ventures plans to allocate as much as 10 million euros per startup.

“As the electricity sector moves at unprecedented speed, we want to work with the most promising startups, with a clear focus on projects that represent growth opportunities. The coming years will be challenging for the energy transition, and we want to face them with the best ideas on a global level,” says Ana Paula Marques, CEO of EDP Spain, a subsidiary of Lisbon, Portugal-based energy company EDP Group.

Houston-based EDP Renewables North America is part of Madrid, Spain-based EDP Renewables, the world’s fourth largest producer of renewable energy. It’s investing 1 billion euros in innovation efforts by 2025. EDP Group is the majority shareholder of EDP Renewables.

The Houston division builds, owns, and operates wind farms and solar parks throughout North America. EDP Renewables North America oversees 58 wind farms and nine solar parks.

Among the nine solar parks is the $280 million, 240-megawatt Cattlemen Solar Park in Milam County, between the Austin metro area and Bryan-College Station. The park is scheduled to start generating electricity next year. Meta, the parent company of Facebook, recently signed a long-term, 156-megawatt power deal with EDP Renewables North America.
