Industrial processes = 25% quarter of global CO2. SepPure, Rondo and OzoneBio aim to decarbonize all that
Richard Ellis

Every sector wants to decarbonize. Perhaps none will have a harder time of it than industry, as the materials and products we use daily often rely on fossil fuels for energy, heat, and feedstock. In 2022, steel, cement, chemicals, aluminum, paper, and light industry generated a quarter of global CO2 emissions according to the International Energy Agency (IEA). For net-zero by 2050, the IEA estimates that industrial emissions must fall 3% per year on average.

The SOSV Climate Tech Summit (Sept 26-27 / free & virtual) gathered a panel of startups aiming to decarbonize chemical separation, industrial heat, and plastics. Can they convince industrial conglomerates to adopt and scale their technologies?  

The sectors in question are considered “hard to abate” because they demand breakthroughs in science and engineering rather than mere changes in fuel sources. Moreover, industrial plants have long lifespans, so companies hesitate to retire assets that have decades of use left. The startups in this panel must demonstrate that their methods can match or outcompete the old means of production both on quality and long-term costs.  

SepPure Technologies has developed a heatless method for chemical separation, a process used in food, pharmaceutical, and petrochemical production. While chemical separation normally requires energy intensive heat, SepPure reduces energy requirements by 90% by using proprietary nano-filters that separate chemicals at the molecular level. A graduate of SOSV’s HAX startup program, Singapore-based SepPure raised a $12M Series A in February 2023 led by SOSV with Anji MicroelectronicsRealTech HoldingsSEEDS CapitalEPS Ventures, and others participating. Dr. Mohammad Farhani, founder of SepPure, joined the panel.

Rondo Energy has developed a refractory brick heat battery that converts intermittent energy sources like wind and solar into a continuous supply of industrial heat and energy. Based in Alameda, Calif., the company aims to eliminate 15% of global CO2 emissions in 15 years and has partnered with Siam Cement Group (SCG) to build the world’s largest battery factory in Thailand with an annual capacity of 90 GWh. Since 90% of industrial processes require heat (per Rondo’s estimate), the addressable market is massive. On August 18, Rondo announced $60M in new funding from a mix of VC and industrial heavyweights including Breakthrough Energy VenturesEnergy Impact Partners,  TITAN Cement GroupMicrosoft’s Climate Innovation FundRio Tinto,  Aramco VenturesSiam Cement, and John Doerr.  Founder and CEO John O’Donnell joined the panel.

OzoneBio converts toxic waste into valuable materials and products using a process called “dead cell fermentation.” The company has successfully used “zombie cells” (cells that have stopped dividing) from plant matter to produce the commercially important (think yoga clothing) Nylon6,6 polymer in way that eliminates the N2O emissions – a greenhouse gas 300 times more potent than CO2 – – associated with the current petro-checmical-based production methods.  A graduate of SOSV’s IndieBio startup program, OzoneBio has raised funding from SOSVLowercarbon Capital, and Accelr8. OzoneBio founder and CEO Dr. Khorcheska Batyrova joined the panel.     

Duncan Turner, General Partner at SOSV and Managing Director of HAX, moderated the discussion.
