World’s first large scale biocarbon production facility to replace coal being built in California


California Construction News staff writer

Aymium, a producer of renewable biocarbon products, has closed on $210 million of financing to construct a biocarbon production facility in Williams, California. The facility will support the world’s first large-scale continuous use of advanced biocarbon to replace coal in power generation.

Use of the product from the Williams facility to replace coal will reduce greenhouse gas emissions by over 500,000 metric tons per year—equivalent to removing over 120,000 cars from the road annually. Construction of the facility is scheduled to be completed in 2025.

“We are excited to have the support from such an experienced group of investors from Asia, North America and Europe,” Aymium CEO James Mennell said in a statement. “These groups share a profound commitment to decarbonization and have come together to advance this technology that will create a substantial reduction in greenhouse gas emissions for many years.”

The facility will be funded by a global group of investors dedicated to next-generation decarbonization technologies. Senior debt, in the form of green bonds, will be provided jointly by ECP ForeStar and Copenhagen Infrastructure Partners (CIP) through its Green Credit Fund. Subordinated debt will be provided by Japan Green Investment Corp. for Carbon Neutrality (JICN) and Aymium. Equity for the project will come from Hokuriku Electric Power Company, Nippon Steel Trading, and Aymium.

“A global threat like climate change demands a global solution. The only way to tackle a challenge of this magnitude is by thinking and collaborating across borders,” said U.S. Ambassador to Japan Rahm Emanuel. “With the United States and Japan cooperating on a multitude of areas related to energy and the environment, Aymium’s groundbreaking biocarbon production facility is the latest project to benefit from this flourishing relationship.”

Aymium produces the only commercially demonstrated carbon-negative product for replacing coal in power generation. Aymium’s renewable product is created through a non-combustion process that converts waste biomass to high purity biocarbon. The product is specifically engineered to immediately replace fossil coal without the need for any type of plant investment or process modification.

The product has superior energy value, handling, and environmental attributes to coal through a process that uses third-party certified sustainable waste biomass and is powered by self-generated renewable energy.

Also, Aymium’s bioproducts are renewable, carbon-negative and they replace emission-heavy fossil fuels such as coal and coke. Aymium says its technology is backed by more than 500 issued or pending patents on a global basis. Aymium is headquartered in Minnesota.
