Energy efficiency: a key element for reducing emissions

Energy efficiency is one of the most effective ways to reduce greenhouse gas (GHG) emissions. It requires a continuous process of searching for opportunities for improvement in the fields of technology, design, and operation and maintenance procedures. Energy efficiency has always played a part of our projects and operations, being prominent since 2006 in ambitious plans and goals to reduce the energy and carbon intensity of our operations.

  • Efficiency to reduce emissions

    The permanent monitoring of our energy and carbon plans aims to guarantee operational excellence of our processes in terms of energy, which is fundamental for reducing our carbon intensity and progressing toward the goal of net zero emissions by 2050. In 2018, we drew up a new emissions reduction plan for the 2018-2025 period with the aim of achieving a reduction of 3 million tons of CO2e by 2025 and encompassing methane and routine flaring reductions.

Reducing routine flaring

Flares are a key factor in ensuring that our facilities are safe and the environment is protected. Since 2016, we have adhered to the World Bank’s Zero Routine Flaring by 2030 initiative, in which we commit to finding viable technical and economical solutions for minimizing routing flaring as soon as possible and no later than 2030. Our goal is to reduce CO2e emissions emitted from this activity by 50% by 2025 in E&P operated assets, whose baseline was established in 2018.

Reducing the intensity of methane emissions

We believe that natural gas plays an important role in the energy transition, which is why we have taken on the goal of reducing methane emission intensity by 25% in our operated assets by 2025, compared to 2017 figures. This commitment is in line with the joint objective with the OGCI initiative (Oil and Gas Climate Initiative) established in 2018. In order to achieve this goal, we must implement more precise technologies for emissions detection, quantification, and reduction, as well as transition to a lower-emissions portfolio.

Low-emissions technologies and renewable energies in our operations

In order to make our processes more efficient and our operations less carbon intensive, we will integrate renewable energies into our refining operations through the production of green hydrogen and the incorporation of renewable electricity for powering our industrial processes.

The first energy company to issue a Green Bond

In 2017, we issued a certified green bond valued at €500 million and became the first Oil & Gas company to use this type of asset. It will be used to fund over 300 initiatives designed to improve energy efficiency and reduce CO2 emissions. In May 2020, we reached our investing commitment to finance projects for emissions mitigation in order to reduce CO2 by up to 1.2 Mt in our operations.

Energy efficiency projects in our facilities

  • Pipelines in the project rephen facilities

    repHEN (Repsol Heat Exchanger Network)

    This tool monitors fouling in heat exchangers, and is used in all refineries. It allows us to define optimal cleaning strategies, make the most of sudden shutdowns, identify opportunities to improve equipment and processes, and analyze investments to implement online cleaning, therefore increasing CO2 reduction from 3% to 10%.

    Replacement of compressors

    Replacement of two compressors for a more efficient model with a variable speed motor in the Petronor refinery in Muskiz (Spain), which allow for the optimization of power consumption, therefore leading to a 77,000-metric ton reduction in CO2 emissions each year.

    Improving the efficiency of furnaces

    Two new air preheaters were installed in two furnaces at the refinery in Cartagena (Spain) in order to recover residual heat and thereby reduce CO2 emissions by 14,000 metric tons per year.

    Oil well optimization

    Development of a tool to evaluate electrical submersible pumping systems in the oil wells of Block 16 and 67, located in Ecuador. This action reduces CO2 emissions by 5,500 metric tons each year.
Through the Oil & Gas Climate Initiative Investment Fund, we invest in solutions aimed at reducing carbon dioxide emissions by increasing energy efficiency.

Calculating our products' carbon footprint

We analyze the carbon footprint of our products in all stages of their life cycle. The methodology that we use for the calculation is ISO 14067 based, an international standard that validates the rigor of our work. Energy efficiency projects are fundamental in reducing the carbon footprint at the stages in which we have operational control.
