The renewable energy sector is a relatively new market that Chemex Global has been active in since 2017.  Renewable fuels like ethanol, biomethane, biodiesel, and renewable diesel are made from different kinds of organic matter such as vegetable oils, animal tallow, and used cooking oils and greases. Finding ways to utilize these materials can be cleaner and creates new opportunities for savings and recycling solutions for various industries.

Our success within this renewable energy market is a result of applying our deep expertise from other types of well-known energy projects and developing renewable project development expertise and new modular options for customers. Over the years, Chemex Global has been involved in the development of renewable diesel projects employing most major renewable diesel technologies. Our recent experiences allowed us to build an unparalleled project estimating expertise and library of vendor information and pricing for all types of projects, from feed pre-treatment, to the RDU, to hydrogen generation, to the balance of plant.  Whether a customer is thinking of a unit conversion or greenfield project, Chemex Global provides affordable value addition to any renewable diesel project development process.

Chemex has experience in all types of renewable energy projects, from biodiesel to municipal solid waste gasification, and we specialize in renewable diesel.

Exemplary Project: Haldor Topsoe HydroFlex Renewable Diesel Unit 

This renewable diesel unit is one of the first greenfield installations of this technology in North America.  This unit will convert beef tallow, pig fat, and distiller’s corn oil to D975 compliant renewable diesel which is a complete drop-in substitute for regular diesel.
