We are excited to announce the creation of our newly formed sustainability company, Zachry Sustainability Solutions, LLC, a Zachry Group company, focused on supporting our customers as they pursue their most critical energy transition projects.

Learn more in our press release.

Zachry has helped its customers for nearly 100 years meet challenges and recognize opportunities in a wide array of market conditions. Our work commonly includes capacity additions, plant modernizations, environmental upgrades, and other technology enhancements for new and existing critical manufacturing and generation assets. Today, we are engaging in important work to help many of our customers navigate the energy transition toward decarbonization.

Our Zachry Sustainability Solutions business has four key focus areas:

  • Hydrogen
  • Carbon capture and sequestration
  • Renewable fuels and chemicals
  • Nuclear energy

Our engineering and project execution teams provide our customers with the insights they need to make informed decisions: What are the relevant technologies for the current opportunity or challenge? What potential solutions are most feasible, technically mature, and commercially viable? We enable our customers to make these decisions with greater certainty and predictability around cost, time to implement and ultimate asset performance, and we deliver turnkey solutions spanning the concept, feasibility, definition, and execution phases of these projects.

The journey with Zachry will be defined by your requirements and goals. We can engage early in the process with understanding the business objective, collaborating on concept development, maturing engineering design and successfully completing construction execution. We are a flexible, knowledgeable partner for technology acquisition, process engineering, power design and implementation. As always, safety and stewardship are at the front of each engagement and lead our actions on every task we plan and undertake.
