Solaris provides products and services that help the oil and gas industry minimize the environmental impact and cost of hydrocarbon production by providing innovative products and services that improve efficiency, lower emissions and reduce well site footprint. We also continually seek to minimize our own environmental impact in our manufacturing activity, field services operations and corporate functions.

100% Electric Fleet

Our Mobile Proppant Management and Mobile Chemical Management Systems are all electric and do not rely on hydraulics. The traditional benefits of all-electric technology include:

  • Elimination of hydraulic fluid on site, resulting in fewer drips and spills.
  • Reduction in carbon emissions.
  • Improved reliability, which reduces time required to complete an operation.
  • Reduction in live diesel fueling, which also leads to fewer drips and spills.
  • Lowered noise level impact.
  • Ability to receive power from the same generation source used by the growing number of electric frac fleets (“e-fleets”) now being deployed to the market.

Dust Reduction

Each of our Mobile Proppant Systems is equipped with dust collection technology on the top of each silo that filters and collects dust, then automatically returns any dust back into the silo, where it is ultimately pumped downhole so that silica waste does not have to be disposed of separately. Our systems are also equipped with automation technology that allows us to enclose the blender hopper, further reducing the risk of potential dust exposure.

Smaller Well Site Footprints

Solaris’ technology allows oil and gas producers to significantly reduce the amount of land required to store and deliver sand, water and chemicals by storing these materials vertically. This smaller footprint reduces the overall environmental impact and lowers costs due to reduced pad construction, development and reclamation required.

Energy Efficient Lighting

Built in LED lights on the top and bottom of each silo system offers enhanced lighting of the well site and replaces legacy light plants. This eliminates another diesel engine and reduces fuel consumption and emissions for our customers and surrounding communities, while providing safer lighting conditions.


Solaris generates emissions in two primary ways – 1) by our fleet of light duty service trucks and 2) by the diesel generators that power our equipment in the field. We have implemented programs over time, such as our remote monitoring system to reduce the fuel consumption and emissions from each source and focus on continual improvement.

  • Safe Mile Program – Solaris has implemented a truck monitoring program to track miles driven, speed, driving behavior and idle time. Truck idle time can be a source of unnecessary fuel consumption and emissions. By monitoring this and holding our fleet personnel accountable, we have reduced idle time by approximately 50%.
  • Electric Power – In 2019, we began converting a portion of our fleet to integrate with electric frac fleets for power generator. When running off electric power, our systems can operate largely emission free, produce fuel savings for our customers and allow for better uptime of our equipment.
  • AutoHopper™ – We recently introduced a technology called AutoHopper, which allows our system to be operated automatically using machine learning and remote sensors. Automatic operation of our system can help prevent the spillage of sand on a well site and allows for less fuel consumption by reducing the need to bring equipment to the well site for sand clean up after the job is completed. The automatic functionality also enables customers to remove a worker from the well site, resulting in enhanced health and safety.
  • Preventative Maintenance Program – Our field service technicians follow a preventative maintenance program that includes a daily checklist for each system to ensure that all components operate properly, and that oil and filter changes are done regularly, which helps enhance the fuel consumption efficiency of our generators.

Fewer Trucks on the Road

Solaris’ technology helps to reduce emissions for our customers by reducing the number of sand and chemical truck trips required to keep a buffer of inventory at the well site. Several competing sand storage technologies require up to 15-20% more trucks to deliver and store the same amount of sand on a well site.

Our Mobile Proppant Management Systems can unload up to 24 trucks at one time, subject to footprint availability on a well site. The ability to unload multiple trucks at a time reduces emissions from potential truck demurrage, or truck wait/idle time. Many competing technologies are limited to unloading 1-2 trucks at a time, which can result in significant demurrage at the well site and can contribute to increased emissions when compared to the Solaris Mobile Proppant Management System.

In our Mobile Chemical Management product line, our system reduces trucks on the road via its ability to blend raw chemical into diluted form “on the fly.” This reduces truck traffic because it eliminates the need to bring certain raw chemicals to a central warehouse, dilute the product and then truck it to well sites in diluted form.


Water Management

Solaris’ primary use of water is in our manufacturing plant, where water is used for fabrication, cleaning, testing, cooling and other industrial uses. We are committed to efficient water use and have integrated water treatment and recycling into our operations at our manufacturing plant in Early, Texas.

For example, all water we use for testing our chemical silos is captured and recycled. We also have invested in a water filtration system so that any water that is not reused meets the city’s regulatory standards before it is returned through the stormwater drainage system. As we only operate in the United States, we do not consume fresh water in regions with high levels of water stress.

From 2018 to 2019, we cut our water consumption in half, largely due to reduced manufacturing activity in the Early plant.

Electricity Consumption

Solaris’ primary electricity use is at our manufacturing plant in Early, Texas, but we also purchase electricity for use at our transloading facility in Kingfisher, Oklahoma, at our storage facility in Monahans, Texas, and at our corporate office in Houston. In 2018, we consumed approximately 2.2 GWh of electricity. In 2019, we reduced our electricity consumption by approximately 30% to a total of 1.5 GWh. Our decline in electricity consumption is attributed largely to reduced manufacturing activity; Solaris’ electricity use in Early fell over 50% from 2018 to 2019.

Electricity generation in Texas continues to shift towards renewable sources and the fuel sources of our electricity consumption will also change as a direct result. According to the Electric Reliability Council of Texas (ERCOT), approximately 31% of electricity in 2019 was generated emission free, which consisted of roughly 20% of electricity generation from wind and another 11% from nuclear. Natural gas contributed 47% and coal 20%. However, these figures continue to shift towards a mix that favors renewables due to rapidly growing wind and solar capacity. In June of 2020, Texas reached a new daily wind generation record of 21,375 MW, or 59% of total electricity generated that day. As of October 2020, Texas boasts more installed wind capacity (24,976 MW) than any other state in the nation. Link to: ERCOT Quick Facts

Energy Consumption

Solaris consumes energy from diesel fuel, gasoline, natural gas, and electricity. Energy consumption constitutes a very small portion of Solaris’ total revenue and costs.

Our total fuel and utility expense as a percentage of our total operating costs, excluding depreciation and third-party trucking costs, averaged around 2.9% for 2018 and 3.2% for 2019. The drop in 2019 is related to a reduction in fuel and utilities consumed by our manufacturing operations.

Commitment to Reuse and Recycling

In all our operations, including manufacturing and corporate, we recycle packing materials and electronic waste. At our manufacturing facility in Early, Texas, steel is our primary raw material, and we reuse or salvage scrap metal created in our manufacturing process.
