Focusing on sustainable, renewable power supply
Starting in 2020, Bosch will compensate for any residual and unavoidable carbon emissions primarily by buying green power from legacy plants and taking part in carbon offset programs. The company is investing in environmental projects, certified to rigorous standards, aimed at supporting social and ecological development. Carbon offsets are to be gradually scaled back by 2030, and Bosch is stepping up investments in renewable energies to this end. It also intends to enlarge company-owned photovoltaic systems such as those in place at the Nashik and Bidadi locations in India. The company expects to achieve a tenfold increase in installed energy capacity with this move. Bosch will also sign long-term, exclusive supplier contracts with new wind and solar farms around the world, which can then operate profitably even without government subsidies.
A billion euros – and connected solutions – for greater energy efficiency
Enhanced energy efficiency is a powerful tool for achieving carbon neutrality. Bosch will invest a billion euros in the energy efficiency of its plants and buildings over the next ten years. “We want to reduce energy consumption and carbon dioxide emissions in absolute terms, and not just relative to value creation,” Denner says. By 2030, the company plans to save additional energy amounting to some 1.7 terawatt hours. This is more than one-fifth of its current annual consumption, and comparable to the amount of electricity consumed by private households in Cologne. Bosch has been vigorously pursuing environmental management practices for years. In 2018 alone, the company carried out some 500 energy-efficiency projects, reducing power consumption by close to 1.5 percent. Connected manufacturing has also become a key efficiency driver. Bosch has already deployed its proprietary energy platform, a part of the company’s portfolio of Industry 4.0 solutions, to more than 30 factories around the world. This platform is a cloud-based software solution that can track and control every single machine’s power consumption.
Climate action pays social and economic dividends
In the years up to 2030, the company will incur one billion euros in added costs by buying green electricity, engaging in carbon offset programs, and sourcing power from renewables. In that same period, Bosch will invest one billion euros to boost in-house energy efficiency. This increase in energy efficiency will save Bosch around one billion euros, thereby bringing the company’s expenditure on carbon neutrality down from around two billion to one billion euros by 2030. “Carbon neutrality is doable and, if pursued with the necessary determination, can be achieved quickly. Our investments benefit not only us at Bosch, but humankind in general as well,” Denner says.
A selection of exemplary Bosch projects
The Feuerbach plant – energy efficient thanks to people and machinery
Feuerbach, Germany, is home to Bosch’s oldest location worldwide. Established in 1909, it has steadily and systematically modernized its facilities to contribute to the company’s overall energy efficiency. With training sessions in its “Energieerlebniswelt” (energy experience world), the local team focuses on energy monitoring and increasing awareness among the workforce. The plant has pursued heat recovery, room automation, machine power shut-off management, and shop renovation projects with great success. Its energy requirements are down more than 50 percent compared with 2007; its carbon emissions – relative to value creation – are down 47 percent.
Crunching data to conserve energy at Homburg
The Bosch location at Homburg, in the German state of Saarland, is edging ever closer to the vision of an energy efficient, self-learning plant. It has spared the world around 5,000 metric tons of carbon dioxide in the past two years and more than 23,000 tons since 2007. This approach pairs maximum transparency with technical innovation. An energy management platform developed by Bosch uses data from the machinery collected at some 10,000 measuring points. Associates can track, control, and optimize each individual machine’s power consumption. Technical solutions include ventilation of manufacturing shops on an as-required basis, utilization of waste heat from various machining processes, and smart consumption management for machinery.
Green roofs, photovoltaic systems, and carbon neutrality at Renningen
The Bosch location at Renningen has been carbon neutral since January 2019. Carbon offsets fully compensate for the carbon footprint of the natural gas burned by its heating system. The facility buys green electricity to cover its power needs. And the 460 photovoltaic modules installed on the roofs of buildings generate electricity for the campus’s own use. To help control temperatures inside the buildings, roofs on the research campus are covered in greenery; a 3,600 m3 underground cistern collects rainwater that seeps through the plant cover for use in the air-conditioning system’s cooling towers. The green rooftops also provide an insulating buffer against direct sunlight and excessive accumulation of heat on the roof. This combination reduces the amount of energy needed to air-condition buildings by 20 to 30 percent. The location also operates a water treatment plant that enables Bosch to conserve around 20,000 m³ of drinking water a year.
Sustainable heating at Rodez
Reduce the site’s carbon footprint – that was what the team at Rodez in France set out to do when it started making plans as far back as 2009. The location now has a biomass heating plant, up and running since 2013. It burns wood chips obtained from local certified sustainable forestry resources. Rodez uses its power to heat water and generate process heat. On average, the wood chip-fired plant covers 90 percent of the location’s heating requirements. It consumes some 6,600 metric tons of wood chips a year. Burning this biomass releases no more carbon than the trees had taken from the atmosphere. The factory has reduced its yearly emissions by around 600 tons.
Reducing the carbon footprint at Bidadi and Nashik, India, with power generated on site
Bosch India is pursuing carbon neutrality by tapping locally available, natural sources of energy. Spurred on by the idea of supplying the location with fully renewable power during daytime hours, the team at the Nashik location began installing its first photovoltaic systems in 2015. It now has 50,000 solar panels in place on roofs, parking lots, and the grounds to generate around 20 percent of the power required by the plant each year. The facility has reduced its carbon emissions by some 23,000 tons and saved around 25,000 megawatt hours of energy since 2015. This is equivalent to the power consumed by some 23,500 Indian households. Bosch experts have also developed an eco-friendly solution for cleaning the modules: water is recycled several times and purified using environmentally sound methods.
The Bidadi plant, located around 1,100 kilometers south of Nashik, has also embraced solar power. This location is able to cover around 30 percent of its energy needs with a photovoltaic system that also offers a further benefit: it provides ideal conditions for growing vegetables and herbs to keep the plant’s cafeteria well stocked with local produce. The sun is not the only resource put to good use at this location, which also channels rain into a small lake to replenish the water supply for the local population.
Renewables as the main source of power for Bosch in Mexico
Mexico has revamped its energy policy. An energy reform launched there calls for the country to source 35 percent of the electricity from non-fossil fuels by 2024. With many hours of sunshine annually and high-wind regions, Mexico’s geography and climate would certainly support that goal, providing a solid foundation for change alongside committed support from government and business. Bosch is part of this movement, and has already set a high standard: power sourced exclusively from the Dominica wind farm in the state of San Luis Potosí covers more than 80 percent of the energy requirements of all Bosch locations in Mexico. Bosch Mexico was able to save 56,000 metric tons of CO2 in 2018 by switching to predominantly renewable energies.
