A new voice for a bright future.

We are passionate engineers convinced by the role of nuclear energy in the energy transition and for a carbon-free world.

Our purpose

We founded the think tank Horizon 238 to explain and share our realistic vision of the energy transition.

We are convinced that renewable energies will be at the center of this transition to a low-carbon world.

However, they will need another energy source to form a clean energy mix, without fossil fuels (gas, oil, coal).

One energy can fulfill this role: nuclear power.

The law governing our energy future was passed 18 years ago!

Did you know? The law on the gradual phase-out of nuclear energy in Belgium was passed on January 31, 2003. However, it is the young generation that will bear the brunt of it.

Another era, a completely different context

In 2003, the iPhone did not exist and the Kyoto Protocol (reduction of greenhouse gas emissions) had not yet entered into force. Nearly two decades later, the context is profoundly different and climate issues have taken on a considerable scale.

Belgian nuclear expertise still at the forefront

Since then, nuclear science has constantly evolved. Research in Belgium has actively contributed to the development of new technologies ready to meet the challenges posed: waste management, nuclear safety, and production flexibility.

A decision against the tide

While all efforts must be directed towards reducing our emissions, the 2003 law will deprive Belgium of a low-carbon energy: nuclear power.


Extending Doel 4 and Tihange 3 would maintain the expertise of Belgium’s industry and leave us with a valuable option: that of using new nuclear technologies to decarbonize our society. Modernizing the 2003 law is possible since Sweden did the same in 2010.

The Belgian electricity mix

2019, a low-carbon mix

Today, nearly half of the electricity in Belgium comes from its nuclear reactors which produce low-carbon electricity. Another third of Belgium’s electricity is produced from fossil fuels (mainly natural gas).

2030, back to fossil fuels

According to EnergyVille, if nuclear power is phased out in 2025, the share of fossil fuels could reach up to 56% of Belgium’s electricity production. This is almost double today’s figure.

Let's prepare the future...

Prioritizing the phase-out of nuclear rather than fossil fuels is a step backwards in the fight against climate change.

According to a recent study by Ember, Belgium will be the only European country to increase its dependence on fossil fuels over the next decade.

... using low-carbon energy

Nuclear energy was developed in Belgium in the 1970s to reduce our dependence on oil.

Today, nuclear power can play a similar role with gas and facilitate the transition to renewable energies.

What is the energy transition?

The need to decarbonize the entire economy

Electricity generation is only the tip of the iceberg. A successful energy transition will involve electrification and the elimination of fossil fuels in heat production and transportation.

With three energy vectors

Energy vectors are the means of transporting energy.




Using nuclear power to support renewable energies

Nuclear energy is low-carbon and is perfectly suited to the production of these three energy vectors.
Furthermore, it can be flexible and become the ideal partner for renewable energy in the energy transition.

To decarbonize the industry


To make up for the lack of renewable energy pools

Demystifying nuclear

In climate science, those who know the most are the most worried.
In nuclear science, those who know the most are the least worried.Stewart Brand

For too long, the nuclear sector has suffered from caricatures and failed to respond to the doubts of the general public.

We are convinced that it is our responsibility as engineers to explain nuclear science transparently so that it can be understood by all.

Those who inspired us

Michael Shellenberger

Nuclear has saved more than two million lives to date by preventing the deadly air pollution that shortens the lives of seven million people per year.

Jean-Marc Jancovici

Today, the urgency is to […] divide CO2 emissions by three in order to avoid global warming that could set the planet on fire and cause bloodshed, and this requires the elimination of all coal-fired power plants within the next 35 years. Without nuclear power, there is no chance of achieving this.

Arjen Lubach

If we want to save the climate, we really need to start thinking differently and see nuclear energy as a serious option.
