CAPSTONE GREEN ENERGY (NASDAQ:CGRN) RECEIVES FOLLOW-ON ORDER FOR 800KW ENERGY SYSTEM AT KOREAN SEWAGE TREATMENT PLANT

RECEIVES FOLLOW-ON ORDER FOR 800KW ENERGY SYSTEM AT KOREAN SEWAGE TREATMENT PLANT

Green Energy System Will Use Biogas to Generate Electric and Thermal Energy

VAN NUYS, CA / ACCESSWIRE / November 22, 2021 / Capstone Green Energy Corporation (www.CapstoneGreenEnergy.com) (NASDAQ:CGRN), (“Capstone,” the “Company,” “we” or “us”), a global leader in carbon reduction and on-site, resilient green energy as a service, today announced that its Distributor in Korea, CY Tech, has obtained a follow-on order for a Capstone 800kW green energy system for installation at the Noksan Sewage Treatment Plant in Busan, Korea. The new installation follows the successful implementation of a 600kW energy system at the Nambu Sewage Treatment Plant, which is also located in Busan.

According to the World Resource Institute, the world needs more energy to support growing populations and expanding cities. Using waste for energy is a cheap, renewable, and readily available form of energy for many cities. Since sewage treatment plants can use biogas generated from their own sludge to power their operations, it allows them to be energy self-sufficient. This ensures that a sewage plant’s primary function — removing pollutants and disease-causing pathogens — is not interrupted by surrounding power outages.

According to the EPA, methane makes up 16 percent of global greenhouse gas emissions, and it’s extremely potent-about 30 times more powerful than carbon dioxide. Sludge-to-energy systems harness this methane for energy instead of letting it escape into the atmosphere, where it would fuel climate change. Although methane releases carbon dioxide when harnessed for energy, the net emissions are negligible if methane-rich biogas is being used in place of fossil fuels in solutions like Capstone energy systems.

The Noksan site, which is capable of processing sludge at 160,000 m3/day, will use the biogas produced in the digestion process as fuel to provide on-site power for the 15-building treatment facility as well as the heat required for the digester. The new system will replace an aging digester with a new one in combination with the system installation.

Because the plant is located within the city of Gangseo-gu, Capstone Green Energy systems were selected for their low noise impact and low environmental impact. The system expansion is expected to be commissioned in September of 2022.

“The original Capstone Green Energy systems we installed has been working so well, we thought it was a sound investment to expand our capacity,” said Ohjun Kwon, Project manager of Busan Noksan Sewage Treatment Plant. “We chose Capstone’s technology for its strong performance, reliability, low noise, and minimal maintenance intervals, which have proven successful operation in several domestic sites.”

“Wastewater treatment plants like the one in Busan have a unique opportunity to take advantage of their methane-rich biogas, which offers a free, renewable fuel source for producing heat and electricity,” said Darren Jamison, Chief Executive Officer of Capstone Green Energy. “Not only does it help reduce operational costs, but it also provides an important step forward in the fight against climate change by eliminating waste gas, which could otherwise be a global warming pollutant.”
