Plans for conversion to a Biomass Carbon Removal and Storage (BiCRS) Project

Back in the early days of the Space Race, popular culture envisaged aerospace technology that might one day have us all zooming around town like George Jetson in his flying car. That hasn’t turned out to be the case, but developments that have evolved from rocket technology could one day play a different role here in the 21st century, where producing cleaner power and managing the energy transition are two key global goals. In today’s RBN blog, we look at an innovative “bioenergy with carbon capture and sequestration” (BECCS) project being undertaken in California by Clean Energy Systems (CES) and its partners, how the company’s technology is designed to work, and what “carbon-negative energy” might mean.

RANCHO CORDOVA, Ca, September 29, 2021 - Clean Energy Systems ("CES"), a pioneer in oxy-combustion technology, announced today that it has raised $15MM in a Series A funding round led by Carbon Direct Capital Management LLC ("Carbon Direct"). The funding will accelerate the first commercial-scale deployment of CES technology in the carbon negative power project in Mendota, California. Carbon Direct will join Clean Energy Systems' board of directors. As announced on March 4, 2021, CES is collaborating with Schlumberger New Energy, Chevron Corporation, and Microsoft to develop a carbon negative power project in Mendota, California. The plant will convert local agricultural waste biomass into a renewable synthesis gas that will be mixed with oxygen in a combustor to generate electricity. More than 99% of the carbon from the process is expected to be captured for permanent storage by injecting CO2 underground into nearby deep geological formations. The Mendota project is expected to create up to 300 construction jobs and 30 permanent jobs once the facility is operating. “Our vision is to scale our carbon removal technology to gigaton scale. In the State of California, our projects mitigate pile-burning of agricultural waste and permanently sequester carbon dioxide," said Keith Pronske, CEO of Clean Energy Systems. "Carbon Direct is a leading scientific advisor and financial sponsor to carbon technology companies, and we are delighted to welcome Carbon Direct as an investor. We admire Carbon Direct's commitment to high-quality carbon removal standards and its science-first approach to investing. Carbon Direct’s investment is an important endorsement of our technology. We look forward to ongoing collaboration with the investment team and the senior scientists at Carbon Direct." Based on rocket technology, CES oxy-fuel combustion systems can be used to convert biomass waste into clean power; in the process CO2 is captured and can be permanently removed by storage in geological formations. “Carbon removal is essential to hit our climate goals,” said Jonathan Goldberg, founder and CEO of Carbon Direct. “CES offers cutting edge carbon removal technology that produces commercially attractive, carbon negative power and can lead to wide scale CO2 removal. The technology is ready to deploy today and Carbon Direct is excited to work with CES and its partners to scale this critical technology.” “Waste biomass conversion with permanent CO2 storage can remove CO2 from the atmosphere affordably and with environmental benefits. CES’ technology can help support the State’s aggressive goal to end open-air burning of nearly all agricultural material in the San Joaquin Valley by 2025. Moving forward, it can also help California achieve its forest restoration goals by creating valuable products from low-value forest residues,” said Julio Friedmann, senior scientist at Carbon Direct. “The work we’re doing with Carbon Direct and our partners builds on over 25 years of technology development and demonstration, and we can replicate these and similar carbon capture projects on a global scale,” said Keith Pronske. “This is the beginning of a new generation of energy production that will be both clean and green.” About Clean Energy Systems Clean Energy Systems is a global leader in the development and deployment of carbon reducing energy systems.

Houston, TX, March 4, 2021 —Schlumberger New Energy, Chevron Corporation, Microsoft and Clean Energy Systems today announced plans to develop a ground-breaking bioenergy with carbon capture and sequestration (BECCS) project designed to produce carbon negative power in Mendota, California. The BECCS plant will convert agricultural waste biomass, such as almond trees, into a renewable synthesis gas that will be mixed with oxygen in a combustor to generate electricity. More than 99% of the carbon from the BECCS process is expected to be captured for permanent storage by injecting carbon dioxide (CO2) underground into nearby deep geologic formations. By using biomass fuel that consumes CO2 over its lifetime to produce power and then safely and permanently storing the produced CO2, the process is designed to result in net-negative carbon emissions, effectively removing greenhouse gas from the atmosphere. The plant, when completed, is expected to remove about 300,000 tons of CO2 annually, which is equivalent to the emissions from electricity use of more than 65,000 U.S. homes. “We are excited to welcome Chevron and Microsoft on this exciting opportunity, as it further demonstrates how we play an enabling role to deploy carbon capture and sequestration solutions at scale,” said Ashok Belani, Schlumberger New Energy executive vice president. “We are diversifying our portfolio of projects with partnerships in selected markets and geographies where existing policies and regulations can make projects attractive today. This unique BECCS project in California is a game-changing example of this.” "There's tremendous opportunity to use cloud technologies in the energy sector to help accelerate the industry's digital transformation," said Scott Guthrie, executive vice president, Cloud + AI, Microsoft. "Innovation at this scale is accelerated by our strong relationship, as we work together to help provide a sustainable and clean environment for local communities." “We’re pleased to have strong partners join our efforts to address the challenges of climate change, improve air quality in the Central Valley and make a vital contribution to the local economy by restarting an idled biomass plant,” said Keith Pronske, Clean Energy Systems president and CEO. “Chevron is helping to advance a lower-carbon future,” said Bruce Niemeyer, Chevron's vice president of strategy and sustainability. “We look forward to leveraging our experience working in California, building projects which can be repeated, and operating large-scale carbon capture and storage operations. The project is aligned with our focus on investments in low-carbon technology to enable commercial solutions.” The completed facility will help improve air quality in the Central Valley by using approximately 200,000 tons of agricultural waste annually, in line with the recent California Air Resources Control Board plan to begin phasing out almost all agricultural burning in the Valley by 2025. The bioenergy technology is designed to operate without routine emissions of nitrous oxide, carbon monoxide and particulates from combustion produced by conventional biomass plants. The project is expected to create up to 300 construction jobs and about 30 permanent jobs once the facility is operating. The companies involved expect to begin front end engineering and design immediately, leading to a final investment decision in 2022, and will then evaluate other opportunities to scale this carbon capture and sequestration solution.
