ENERGY, FUEL ECONOMY & EMISSIONS HYDROGEN-FUELED GENSETS In response to customer interest in hydrogen, we announced that some Caterpillar gas generator sets are being configured to use 100% hydrogen on a design-to-order basis. We’ll also have some commercial sets configured to operate on natural gas blended with up to 25% hydrogen. EXPLORING LOW-CARBON SOLUTIONS We entered a memorandum of understanding with Certarus to explore opportunities to bring lower carbon energy solutions to our customers. We are working together to advance the use of lower carbon fuels, including conventional and renewable natural gas and hydrogen. PROVIDING SUSTAINABLE ENERGY SOLUTIONS AROUND THE WORLD We are providing companies and communities around the world with innovative, sustainable solutions. In Sweden, Microsoft is progressing toward its carbon-negative goal with new data centers powered by 100% renewable energy. Yet, in case of maintenance or a grid outage, they need sustainable standby power. Enter our Cat C175-20 and C18 generator sets, which run on locally refined Preem Evolution Diesel Plus — the world’s first eco-labeled liquid fuel, which contains over 50% renewable raw materials. In Rwanda, methane gas at the bottom of Lake Kivu posed a serious risk of rising to the surface and triggering a gas explosion. In response, we partnered with local private and public officials to deliver 19 MWM branded gas generator sets that are transforming the methane gas-water mixture into a sustainable energy resource. The power plant supported by the generator sets will go live in 2022. 29CATERPILLAR 2021 SUSTAINABILITY REPORT
