Fuel choice is one way that customers can reduce lifecycle GHG emissions today. Many Caterpillar products operate on lower-carbon intensity fuels, including biodiesel, renewable diesel and biogas. These fuels reduce lifecycle GHG emissions in the fuel value chain; GHG emissions at the tailpipe are essentially the same as traditional fuels.
For example, all Caterpillar diesel engines can operate on 100% HVO. This includes the Cat C-Series engines a Swedish commercial and industrial equipment supplier uses to power its mining and construction equipment. In 2022, the supplier completed testing its range of machines to confirm they can operate with HVO without modifications to the engines or the fuel tanks.
In addition, Caterpillar engines operating on natural gas blended with up to 100% hydrogen are being demonstrated in power generation projects today; turbines can operate on up to 100% hydrogen. These and other projects are helping to demonstrate the viability of potential fuel sources like hydrogen while the infrastructure to support availability of renewable hydrogen is being developed.
In the maritime industry, we’re committed to supporting our customers’ climate-related objectives through methanol-powered solutions, which are efficient, cost-effective, and meet Caterpillar fuel standards.
Accordingly, Caterpillar Marine joined the Green Maritime Methanol consortium in 2022, teaming up with other companies to streamline the adoption of methanol as a maritime transport fuel. Green methanol, an important candidate as a future fuel for the shipping industry, is easily stored aboard ships and can provide lower carbon intensity.
Caterpillar’s investment in lean burn natural gas technology, microgrid controls, and energy storage has provided our customers flexibility to utilize alternative energy technologies and the opportunity for customers to reduce their carbon footprint. Exploration drilling has historically been powered by diesel or dynamic gas blending (DGB) technology, which consumes diesel and natural gas. Now with a fully integrated solution, Caterpillar can provide customers with a 100% natural gas solution, combining the best from its lean burn engines and microgrid technologies. Drilling rigs powered by Cat natural gas generators, such as the G3512, paired with an energy storage system provide customers with the same industry leading responsiveness experienced with Cat diesel engines. The benefits include a reduction of up to 80% nitric oxide, 11% CO2, and up to 30% engine runtime. With the ability to run on field gas, this gas hybrid solution can reduce the need for flaring while creating a fuel cost savings of up to 85% and reducing operational GHG emissions.
