Borates in Energy

Powering Sustainability

As our population and cities grow, so does our need for safe, sustainable energy. To meet global requirements, we must increase the efficiency of our energy consumption and optimize the capacity of existing and emerging energy sources.

U.S. Borax products are integral to these aims. Whether on the oil field, in the nuclear plant, or across the wind farm, our innovative technologies and borate products help to make energy safer, more efficient, and more affordable.

Sustainable energy

Supporting Sustainability

Solar and wind energy depend on strong, durable materials. U.S. Borax products help to enable these technologies—and we strive to make our own operations sustainable, too.

  • In solar thermal heating applications, borosilicate glass helps to focus and capture solar energy.
  • Textile fiberglass made with borates is important in the creation of wind turbines, and borates are a part of the high-power magnets that are used in turbine generator systems.
  • Aside from providing materials used in sustainable energy production, we make environmental protection and safety key aspects of our own operations. Since 2001, our Sustainable Development program has been a foundation of our commitment.
  • Our Product Stewardship and Health, Safety, Environment (HSE) teams are dedicated to the responsible production and safe use of U.S. Borax products.

Strengthening Infrastructure

Around the world, borate-based chemicals are important to modern oil field operation and recovery as well as the safe and efficient production of nuclear power.

  • The reaction of borates with certain alcohols and carbohydrates produce adhesives and fluids that are used in oil recovery.
  • As an anticorrosive, borates are used to help protect industrial water systems.
  • Borates have the ability to capture thermal neutrons resulting from the fission reaction of uranium nuclear fuel; that ability makes them an essential ingredient in the control and safety of nuclear pressurized water reactors.
  • Elsewhere in nuclear power plants, boron carbide and borates are used for control rods, corrosion inhibition, and emergency shutdown systems.

Improving Efficiency

Borates are used in the production of fire-resistant, high-efficiency insulation and innovative building materials, helping save fuel and energy so that we can make effective use of our natural resources.

  • Borates are used in ceramic tiles and are essential in insulation fiberglass to help improve energy efficiency and decrease heating and cooling costs.
  • As a natural biocide, borates help to control damaging insects, fungi, and bacteria—allowing us to make more efficient use of forest products in construction.
  • Borates are used to stabilize metallurgical slags, helping to keep them out of landfills and encouraging reuse.
