Emissions reduction

What if we were able to reduce CO2 and reuse it as raw material?


At Repsol we want to play an important role in the fight against climate change by improving the sustainability and efficiency of our products and industrial processes, as well as by promoting the development of new low-emissions energy businesses. At the Repsol Technology Lab, we employ innovation and technology to achieve these goals. Our researchers search for solutions throughout our entire value chain in order to make our businesses more efficient and competitive. We also explore ways to reduce the impact of CO2 by reusing it in the creation of new materials to reduce its impact on the environment.

Capture, store and reduce emissions

At the Repsol Technology Lab, we are working to reduce the emissions of our production processes and develop methods for reusing the C02 that has been emitted into the atmosphere. Carbon Capture, Use, and Storage (CCUS) technology involves the capture of carbon dioxide (CO2), its transportation via ships or pipelines, and its eventual use as a resource to create valuable products or services. This technology will play a key role in our objective of achieving net zero emissions by 2050.

Biofuels

We are committed to fuels derived from renewable sources that release CO2 without net carbon emissions when burned.

Renewable hydrogen

Using renewable hydrogen along with low-carbon liquid fuels is vital for decarbonization. Therefore, we continue to focus on developing technology solutions at Repsol aimed at producing low-carbon hydrogen that will enables us to keep advancing towards the energy transition.

CO2 reused as raw material in chemicals and new products

We are developing technologies to convert COfor use as a raw material with a wide range of opportunities, ranging from the synthesis of polymers and the creation of synthetic fuel, to incorporating it into construction materials.

This activity requires expert knowledge in designing processes, products, and applications. CCUS is a set of technologies that is strongly supported by EU Directives as a way to achieve CO2 reduction objectives.

Developing new ways to capture CO2

Carbon capture can be applied on a large scale to many emissions processes, including coal and gas power generation, natural gas processing, and fertilizer production, as well as in other industrial sectors such as cement, iron and steel, paper, and petroleum refining. 

At the Repsol Technology Lab, we are developing new separation technologies with the goal of reducing costs and facilitating the large-scale commercial deployment of CCUS opportunities.

Changing the way we store CO2

Geological storage consists of injecting captured CO2 into rock formations deep underground. Suitable land must have rocks with certain porous and permeable characteristics, as well as upper barriers that serve as seals for permanently containing the CO2.

We are collaborating in the development of tools such as the Society of Petroleum Engineers' Storage Resource Management System (SRMS), which provides guidelines on how to classify storage resources and evaluates maturity levels for consideration in these projects..

Reducing the carbon footprint at refineries

Currently it is estimated that 20% of the CO2 emissions in refining processes is associated with the generation of hydrogen, a component that allows us to improve the technical and environmental quality of our products. To this end, we are developing low emissions technologies like photoelectrocatalysis, which allows for the production of green hydrogen through solar energy.

Our researchers are also working to reduce emissions of methane at refineries. All our refineries now use natural gas in their processes, thus minimizing these emissions due to the lower levels of carbon.

Sector leading partnership rising to the CO2 challenge

The fight against climate change has become such an important challenge that companies in the energy sector decided to join forces to form one large partnership called the Oil & Gas Climate Initiative (OGCI). This voluntary, industry-led initiative is headed by CEOs from the 13 of the world’s major energy companies who want to lead the sector's response to the threat of climate change. 

Among the main focuses of the OGCI is the implementation of CCUS (Carbon Capture, Use, and Storage) technologies and the investment in companies and startups that are developing these technologies through its OGCI Climate Investments fund created in 2016.
