"Blumreiter and Johnson co-founded ClearFlame Engine Technologies to market engine technology that allows trucks, generators and other motors to run on a variety of low-emissions fuels such as ethanol, methanol or liquid ammonia. While these fuels are not zero emissions, various studies have shown pure ethanol’s life cycle greenhouse gas emissions are roughly 40 percent to 50 percent less than petroleum-based fuel."
"A lot of the drivers for recent protests of copper mines, and of the companies producing them, are due to ESG concerns. It remains unclear if the connection will be made that without copper there will be no energy transition, or if the snake will simply keep eating its tail."
"CarbonBuilt spun out of UCLA’s engineering school in 2019. In May, the company began commercial production of its sustainable concrete at a partner facility in Alabama, where an on-site biomass furnace captures and supplies CO2. The company says it now plans to produce its Portland-cement-free blocks at 'commercial volume' in Alabama starting in 2024."
Micro-pumped hydropower systems could provide additional clean energy and energy storage for America's farmers
As demand for PFAS removal services soars, the private sector is stepping in to deliver solutions that have the potential to eliminate even the most pervasive man-made chemicals.
"Based in San Juan, Puerto Rico, the company’s team of engineers, scientists, UX designers, and insurance experts are developing the next generation of parametric insurance in Florida, California, New York and Washington State. Raincoat partners with insurers, reinsurers, and governments worldwide in developing and distributing these solutions."
"Traditional methods of tracking biodiversity include metabarcoding, a type of analysis that looks at short snippets of DNA to identify specific populations of species. The researchers found that bioacoustic monitoring led to similar findings as this more direct method but can be accomplished at a lower cost and with less intrusion on the environment."
"'Ultimately, our plan, our goal would be to develop a credibly lower-cost process to make Portland cement at scale. And, therefore, because it’s lower cost, eventually, our process will replace 100% of cement production facilities worldwide, leading to a fully decarbonized system,' Finke said."
"Air pollution from rudimentary cooking fuels such as charcoal, firewood, coal, agricultural waste and animal dung causes 3.7 million premature deaths per year, ranking it the third largest cause of premature death globally, according to the report."
"'The green ammonia that Talus’s systems produce is both reliable and locally produced, which reduces costs by addressing supply chain insecurity and challenges,' Matt Carstens, Landus’s CEO and president, said in a response to questions. Green ammonia is 'an exciting innovation to consider,' he said."
