Geothermal Energy

Janssen leads the way in the field of ecology by investing in geothermal energy

The Beerse site is the largest energy user of all Johnson & Johnson sites worldwide. Its electricity consumption equals that of 38,000 homes. That’s why we are continually focusing on innovative solutions and sustainable ways of minimizing our impact on the environment. It is, therefore, great to hear that J&J is making significant investments to ensure that from 2019 the campus buildings will be heated and cooled using deep geothermal energy as a green and renewable energy source.

With its focus on innovation and sustainability J&J has set itself the ambitious goal to obtain 20% of its energy from renewable sources by 2020 worldwide. By 2050 this should have risen to 100%. At the same time the company is targeting a 20% reduction in its CO2 emissions by 2020 and 80% by 2050, making J&J’s investment in geothermal energy in Beerse a highly significant project. In fact calculations have demonstrated that utilizing the earth’s deeply embedded heat would reduce CO2 emissions by 30%.

What is geothermal energy?

The principle of geothermal energy is very simple: hot water is pumped from a groundwater layer deep underground, the heat is extracted in an energy plant and the cooled water is returned to the same groundwater layer, where it is warmed up again by the earth's natural heat, making it an everlasting and very environmentally friendly cycle. Research has shown that the groundwater at a depth of 2.4 km below our site has a temperature of approximately 90 degrees, which means that it can be used as an energy source for cooling, heating and even electricity.

Geothermal energy will enable us to develop a local heat network and heat various buildings in a CO2 neutral manner.

Janssen leads the way in the field of ecology

Janssen is the first industrial concern in Belgium to apply this sustainable and green energy source to fulfill its own energy needs. Moreover, Janssen also makes concerted efforts to reduce its environmental footprint in other areas:

  • Green Labs projects for sustainable laboratories

  • Focus on biodiversity to support sustainable nature conservation

  • You.Balance, as a solution to accommodate peaks in energy demand in order to avoid power cuts or black-outs

  • Sustainable waste management

  • PIE project to reduce water consumption

  • Fleet 2017 project as part of a drive to promote greener transport and sustainable mobility

  • Earthwards, J&J program focused on promoting the development and production of green products

By implementing these measures Janssen wants to ensure that our impact on the soil and the air we breathe is kept to a minimum and that we adopt a sustainable approach to energy.

The project was made possible also thanks to financial support from the European Regional Development Fund (1.5 million €), the Innovation and Enterprise Agency (2 million €) and the Flemish Energy Agency (4 million €).
