"Hydrogen has the highest energy density of all chemical fuels and is also very reactive, says Eric Toone, chief technology officer of Breakthrough Energy. This makes it potent. It could be used to make essential but currently dirty things such as liquid fuels, steel and ammonia."

The chlorine atoms then steal hydrogen atoms from methane to make hydrochloric acid (HCl), which can be captured and recycled. The methane atoms decompose into carbon dioxide (CO2), carbon monoxide (CO), and hydrogen (H2), the same way it is processed naturally but at a rate that's roughly 100 million times faster in the reaction chamber."

"Footwear production accounts for 1.4 percent of annual global greenhouse gas emissions, according to a 2018 Quantis study — roughly equivalent to the emissions of Canada. Manufacturing accounts for 43 percent of those emissions, and extracting and processing raw materials 34 percent, the report found. Making a pair of sneakers generates 30 pounds of CO2, according to an analysis by MIT in 2013. A typical shoe contains several materials tightly sewn together — leather, plastic, cotton, rubber, synthetics and so on — and is thus very difficult to recycle. Ninety percent of old shoes end up in landfill sites."

"INL calls itself America’s nuclear energy laboratory, and its core missions include keeping the existing fleet of reactors in service and developing the next generation of fission power plants. A total of 52 reactors were built and operated at the facility as the technology became a mainstream source of electricity. The last new one to go into service there was in 1973, though."

"The cost of producing synthetic graphite from wood using CarbonScape’s technology is competitive with making it from fossil fuels, said Williams, without providing detailed figures. Temperatures required to create graphite from wood chips are lower, and the process takes hours rather than weeks, he said."

"The company said its technology 'is designed to maximize the value of renewable energy generation and offer grid operators control and flexibility at the lowest cost compared to other energy storage options. The system is also modular and scalable by adding more carbon blocks to increase storage duration, allowing growth with the grid as renewable generation increases.'"

"Symbium is part of a wave of software companies looking to speed up notoriously sluggish permitting timelines for renewable energy projects. These startups say approval processes can be tightened up dramatically with the help of automation software."

"CF’s executives decided to capitalize on that potential clean-energy demand and lean a bit less on fertilizer. One advantage for CF is that it can convert its ammonia to a low-carbon variety relatively cheaply, since the company already captures much of the CO2 generated. It just has to sequester that carbon dioxide instead of venting it to the atmosphere, as it does now."
