It sounds like the stuff of science fiction, but it actually comes from a lab in Maryland. In 2018, Liangbing Hu, a materials scientist at the University of Maryland, devised a way to turn ordinary wood into a material stronger than steel. It seemed like yet another headline-grabbing discovery tha

In 2020, Mark Chen's son sent his relatives a brief and unusual Christmas list: In lieu of presents, he wanted carbon credits. “He was 12 at the time,” Chen told technewss. “He came up with the idea. I thought it was great, so I started looking into carbon credits. I stepped into the ch

Plenty of startups hit a wall after their first few rounds of funding, having grown too big for venture funds but still in need of cash. For startups specializing in industrial-scale hardware, which includes many climate tech companies, the problem is especially acute because the capital requiremen

Coal-fired power plants have done their fair share of damage over the past century. From climate change to acid rain, black lung to heart disease, they've generally been on the debit side of the ledger.  But lurking in the literal ashes is something of a minor climate savior.

The U.S. has been building so many solar farms that companies can't find enough people to install the panels. By 2033, the number of solar installers is expected to increase by 48%, according to the U.S. Bureau of Labor Statistics. Even if those labor force growth projections pan out, the indu

Demand for solar energy in power-starved Nigeria has soared in the last decade thanks to worsening grid reliability and rising fuel costs. That's drawn investor interest to Arnergy, a clean tech startup meeting that need. The company just raised a $15 million Series B extension (on top of a $3
