"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."
"Fervo pumps cold water down an injection well, then over hot rock underground to another well, the production well. The path between is created by fracking, or fracturing the rock. The water heats up to nearly 400 degrees Fahrenheit (200 degrees Celsius) before returning to the surface. Once there, it transfers its heat to another liquid with a low boiling point, creating steam. The pressure of steam expanding spins a turbine to produce electricity like in a coal or natural gas-fired plant. The geothermal water, now cooled, is put back down the injection well to start the cycle again, in a closed-loop system."
"A crew without much technical knowledge can manufacture and assemble the structures’ eight panels and the interior bamboo beams that support them on-site. Lari designed them so that homeowners can easily make repairsand even additions...If a flood is coming, homeowners can dismantle the structure’s bamboo skeleton from its permanent foundation and move it to higher ground. Bigger buildings, such as community centers, stand on stilts several feet high."
"Graphyte’s first project in Pine Bluff, Ark., collects waste from two timber mills and a rice-milling operation. The company aims to start manufacturing its biomass bricks in January and burying them in July. By then, it hopes to be making roughly 140 pallets of blocks a day, enough to store 50,000 metric tons of carbon annually."
"The approach has two climate benefits, said CEO and co-founder Todd Brix. First, it uses CO2 that’s captured as an industrial waste from facilities such as biogas and bioenthanol producers or it’s pulled from the atmosphere using a direct air capture device. Second, it generates formic acid and other formate chemicals that can replace fossil fuels as a feedstock for fuels and other products."
Through innovation and ingenuity, the private sector is turning environmental hazards into sources of clean, reliable energy production.
Innovative solutions like the platform developed by Perimeter are needed to prevent as much loss of life as possible.
"Graphyte is in the process of building its first plant in Pine Bluff, Arkansas, near local timber and rice mills that could serve as biomass sources, according to Rogers. It’s also in the process of signing customer offtake agreements, or a contractual commitment to buy carbon removal services at a predetermined price upon delivery. The first carbon blocks are expected to be produced by January 2024. The startup projects the project will have the capacity to remove 5,000 tons of CO2 per year by the end of 2023 and 50,000 by July of 2024."
"Insect start-ups hope large facilities will help them get their foot in the door with big buyers in the market for fish and livestock feed, pet food and fertilizer. 'If you are just [producing] a few tons or tens of tons you don’t exist,' said Antoine Hubert, co-founder of Ynsect,a French start-up that specializes in mealworms. 'This is why we have to design something pretty massive, because you need thousands of tons if not tens of thousands of tons to exist for a single buyer.'"
"Arzeda, which raised a $33 million Series B round of venture funding in March 2022, doesn’t just help companies with discovery. It’s also a co-development partner. It has already worked with Unilever to design, engineer and test the enzymes in real-world testing quantities. The next step will be to scale production of the enzymes and help commercialize them. 'We are getting better and better at the design with every undertaking,' said Arzeda CEO Alexandre Zanghellini."
