Low-carbon heating in France : warming up to District Heating


"District Heating" is a technology allowing several large buildings, neighbourhoods or even entire cities to share common heat sources, which produce heat centrally and then deliver it to each individual home through dedicated heat networks. While the general public may sometimes associate district heating more with Scandinavian, Central- or Eastern European countries, France is also "warming up" to this technology.

Indeed, France's district heating systems have seen an increased share of renewable heat production in recent years, and the government is looking to expand the use of low-carbon district heating even further (the goal being a 5-fold increase by 2030, compared to 2012 levels). According to a recent study, this would also enable the country to tap into local resources in order to create local employment, while also protecting consumers from price fluctuations.

How does Europe define "Clean Hydrogen" ?

The European Union and several of its member states are moving forward to promote clean hydrogen as a new energy carrier for a fossil-free future.  

However, as argued by JJ Bürger in an article for the French utility-centered magazine Usine Nouvelle, the European Union's approach is still too vague, leaving it up to the individual states to define what "clean hydrogen" actually means and how it should be produced. 
The discrepancy among the national approaches hinders the creation of a EU-wide common vision for clean hydrogen technologies, as argued in the article, even though Europe's position on hydrogen could have the potential to set international standards for the emerging market of clean hydrogen.

Integrating flexibility into the power grid of tomorrow

In order for the Energy Transition to succeed, the energy system of the future needs to embrace flexibility in a way that would have seemed unbelievable just a few decades ago.
Indeed, an increasing share of the electricity production will be provided by intermittent renewable resources. In addition, power consumption may become more and more flexible, due to new use cases such as e-mobility or smart homes.

In this context, it is interesting to note that research projects are increasingly focused on enabling real-life applications of Energy flexibility. For instance, the InterFlex project has recently published its final results.
InterFlex was a 3-year project, running from early 2017 to end of 2019, which investigated the use of local flexibilities to relieve distribution grid constraints.
The project aimed to develop solutions for the integration of distributed energy resources and to prepare the electric system for new uses, including electric mobility.
Six industry-scale demonstrators were set up in 5 participating countries. 

The variety of the approaches investigated by InterFlex reflects the diversity of the European energy systems and particularly of the grid infrastructure. The project’s use cases, tested in its six demonstrators in five countries, have provided their individual input to five innovation streams:

France's low-carbon hydrogen ambitions : one year later

According to its strategy launched in 2018, France aims to reach at least 200 heavy-duty vehicles powered by low-carbon hydrogen by 2023 - and at least 5000 light-duty commercial vehicles. The targets for 2028 are even more ambitious, as they foresee to multiply the 2023 targets by at least 4.

In order to reach those targets, France announced an equally ambitious support budget of 100 million EUR (potentially per year) when it presented its hydrogen strategy in June 2018. So far, it does not seem like the reality of the 2019 budget can fully live up to that promise.

Nevertheless: now that the first selection of 11 hydrogen projects was presented this month by the French Energy Agency ADEME, the interest in the emerging market for low-carbon hydrogen solutions is at a new height, and it keeps on growing steadily.

However, in order to reach France's overall objective of creating an entire new industry around low-carbon hydrogen, certain financial and regulatory elements are still needed in order to create solid long-term perspectives.

This is what JJ Bürger describes in an article for the French magazine Usine Nouvelle, specialized on industry and energy topics. Please click here to read the entire article.

Local and regional aspects of the Energy transition : France, Germany, United Kingdom


The energy transition continues to have a local dimension that is very strong. Indeed, large parts of the infrastructure, investments and jobs related to the clean energy sector are deeply rooted in their respective regions. Similarly, opposition against clean energy projects can frequently also have an important local dimension, for example in the form of citizen backlash or regional regulatory hurdles.

An international team of researchers now took on to further analyze these interactions between the energy transition and its local or regional contexts. Published at Lavoisier, the book cites specific examples and compares overall trends between France, Germany and the United Kingdom.

Local and regional aspects of the energy transition in Germany, France and in the UK

The book's contributions on Germany were elaborated by EIFER, the Karlsruhe-based European Institute for Energy Research. The author of this blog also contributed to this work.

The book is currently available only in French language. If you are interested in publications in English or German, please feel free to reach out.

Energy Transition and other challenges for German electricity grids


The energy transition is a challenge for electricity grids in Germany. Conceived for a centralized top-down power supply, the grid now has to integrate an increasing number of decentralized bottom-up power flows, while also ensuring that the overall system continues to run smoothly.

However, the increase of renewable energy in the current decade is not the only reason for this challenge. For example, the fleet of conventional power plants in Germany and Europe is also undergoing profound changes at the same time. In addition, parts of the German power grids are also considered by some experts to have suffered of a certain lack of investment in the late 20th century...

In order to assess the challenges of the German power grids correctly, they have to be portrayed in their actual, multi-facetted context. That is indeed the objective of JJ Bürger's book, which was published at Springer-Vieweg, a publishing company specialized in science and academia:

JJ Bürger - Transformationsprozesse und Stromnetzausbau

This book describes the planning processes of German grid development, and the policies put in place in order to modernize those planning processes for the needs of the emerging, new version of our energy system. Moreover, the book compares these targets with the reality of actual grid development progress. A large number of original sources are also referenced, supporting the book's analysis of the current situation in the 21st century, as well as its succinct review of the history of German power grid development in the 20th century.

The book is currently available only in German language. If you are interested in publications in English or French, please feel free to reach out.

Over 8 years and 100 blog posts

When this blog started in late 2010, who would have thought that it would still be around 8 years later - still alive and actively producing new posts?
It is early 2019 now, and we just stepped beyond the remarkable limit of 100 blog posts!
Many thanks to everybody who has read, followed and shared this journey with me.
Here is to the next milestones that we will reach together!

JJ Bürger

Quand ce blog a démarré fin 2010, qui aurait dit qu'il serait toujours là 8 ans plus tard - toujours vivant et actif ? 
A l'heure actuelle, nous sommes début 2019, et nous venons de franchir le cap des 100 articles postés !
Merci beaucoup à tous ceux qui ont lu, suivi et partagé ce voyage avec moi.
Aux prochaines étapes que nous allons franchir ensemble!

JJ Bürger

Wer hätte gedacht, als dieser Blog Ende 2010 startete, dass er 8 Jahre später immer noch hier sein würde - und immer noch aktiv neue Posts produzieren würde?
Soeben haben wir die Marke von 100 Blogposts überschritten!
Vielen Dank allen, die diese Reise mit mir geteilt, verfolgt und gelesen haben.
Auf die nächsten Meilensteine, die wir gemeinsam erreichen werden !
