Travertine starts operation of demonstration plant

Travertine Technologies, Inc., has began operations at its demonstration plant in New York state. The core Travertine process demonstrated at this plant combines three major unit operations: salt-splitting electrolysis, caustic direct air capture, and mineralisation. This process produces sulphuric acid, calcium carbonate, and green hydrogen from waste gypsum and carbon dioxide captured directly from the air. The demonstration plant will produce 125 t/a of sulfuric acid, 125 t/a of calcium carbonate, and 55 t/a of carbon dioxide sequestration. The plant will supply sustainable sulphuric acid for local partner Sabin Metal Corporation's precious metals recycling and refining business.

Wabash Valley project to abandon CCS

The US Department of Energy has agreed a $1.5 billion loan for the Indiana-based Wabash Valley Resources LLC to finance a coal-powered ammonia plant in West Terre Haute. The project will restart and repurpose a coal gasification plant that has been idled since 2016. However, previous plans to include carbon capture and storage in the project, as agreed as recently as May by the US Environmental Protection Agency (EPA), appear to have been abandoned. The loan comes from the Trump administration’s Energy Dominance Financing Program financed via the so-called “big beautiful bill”. It aims to reduce US dependence on foreign sources of fertilizer and to provide domestic sources of consumption for America’s shrinking coal industry. The facility is aiming to produce 500,000 t/a of ammonia using coal from a mine in southern Indiana as well as petroleum coke as feedstock.

Technology license for blue methanol

Topsoe has been selected as technology provider by Sandpiper Chemicals LLC, for their new blue methanol plant in Texas City, Texas. Topsoe will license its Syn-COR™ technology, which will be combined with carbon capture & storage (CCS) for the production of blue methanol. The project, when operational will produce 3,000 t/d of blue methanol. The IEA estimates that methanol demand is expected to grow to 120-150 million t/a by 2030. Today, methanol is primarily used within the chemical industry, but growing demand is coming from the shipping industry as it looks to lower emissions.
