HEAT NETWORKS TO SCALE UP DECARBONIZATION IN HOUSING

Apolline FAUREStéphane BAUMONTFrederik THUREGaëtan DAUJEAN
Description
District heating networks powered by renewable and recovered energy are among the most powerful tools for rapidly decarbonizing the building sector. Nordic models have demonstrated this for several decades: when well-planned, supported, and connected on a large scale, these networks enable a massive shift away from fossil fuels. In France, the potential remains considerable but is still underutilized. The Multi-Year Energy Plan (PPE3) sets an ambitious goal: to triple the number of district heating networks. This requires a genuine shift in scale: accelerating projects, securing business models, mobilizing local governments, connecting more multi-unit housing, and making better use of local resources. This roundtable will compare European experiences with French realities to identify persistent barriers to deployment: financing, public acceptance, regional engineering, building connections, availability of renewable heat, and local governance. Above all, it will examine the conditions needed to make district heating networks a central tool for the widespread decarbonization of housing. How can the threefold increase announced by the PPE3 be transformed into a truly operational pathway? What role should local governments play in local energy planning?

OFFSHORE WIND ENERGY MORNING SESSION: REGIONS, PORTS, INDUSTRY… THE KEYS TO A VALUE-CREATING INDUSTRY

Arnaud DE VILLEPINMaëlie BENISTAND-HECTOR
Description
Floating wind power is often touted as the next frontier in offshore renewable energy. But behind the installed capacity targets and competitiveness challenges lies a profound transformation of coastal regions and the maritime industry. The development of port infrastructure, the emergence of new industrial supply chains, the creation of jobs and skills, and coexistence with other uses of the sea: what concrete benefits can this sector bring to the regions that host it? Part One – Floating Wind Power: Beyond Costs, What Are the Impacts on Regions? This first session will focus on the economic, industrial, social, and environmental impacts of floating wind power. Beyond the cost per megawatt-hour, how can this sector become a driver of local development, reindustrialization, training, and job creation? Under what conditions will regions be able to sustainably capture the value generated by these projects? Part Two - Floating Wind Power: How Are Ports Shaping a New Industrial Chain? This second session will focus on the conditions necessary to achieve this ambition. Assembling the floats, storing components, transporting equipment, and installing and maintaining offshore wind farms require unprecedented infrastructure and logistics. What investments, which ports, and what partnerships between industry and local authorities will help build a competitive French industry and strengthen the country’s energy sovereignty? Throughout these two discussions, industry representatives, local governments, port authorities, and sector stakeholders will share their vision of the conditions necessary for the success of floating wind power, united by a common ambition: to make this technology a driver of sustainable development for coastal regions and a pillar of France’s energy transition. A roundtable discussion moderated by Olivier Zanetta, journalist and programming director at EnerGaïa

WHAT IS THE FUTURE OF BIOGAS IN LOCAL COMMUNITIES?

Marion TREBOUXRauna BARTH
Description
France’s energy transition is entering a new phase. With its plan to electrify end-use sectors, the government aims to drastically reduce fossil fuel consumption in buildings, transportation, and industry. The 100 selected “electrification regions” will even be required to pilot an accelerated phase-out of natural gas in favor of electricity. In this new landscape, what role remains for biogas? As France continues to set ambitious biomethane production targets and anaerobic digestion projects multiply, must the sector demonstrate that it meets needs that electrification cannot cover: industry, heavy-duty transportation, waste-to-energy, agriculture, and security of supply? Is biogas destined to become a supplementary energy source, reserved for uses that are most difficult to electrify? Can it remain a driver of economic and agricultural development in local regions? How can we reconcile the ambitions of electrification with those of developing renewable gases? A roundtable discussion moderated by Carole Rap, journalist
