Don't miss out the @IA4EE international conference #iaee2021online. I will be presenting an ongoing work about the relative role of different energy carriers and sources in a carbon-neutral future in the presence of #SectorCoupling this afternoon at 5 P.M.
iaee2021online.org/programme_text
This is a revised version of a previous work (⬇️), where I changed several parameters that did not seem realistic regarding transport and heat sector technologies (and some supply and storage technologies' parameters as well):
papers.ssrn.com/sol3/papers.cf…
The method: This is a multi-vector energy system optimization model, where I considered gas, electricity, heat and hydrogen as energy vectors, considering continental France over a single weather year (2006 based on previous findings). Greenfield optimization #EOLES for 2050.
The main conclusions:
1) Social cost of carbon of 200€/tCO2 can lead to carbon-neutrality, where natural gas is eliminated from the primary energy supply
2) System is highly electrified but at least 20% of share for (renewable) gas
3) Very high share of Renewables (up to 100%)
4) Transport and heat sectors are highly electrified in a carbon-neutral energy system ⬇️
5) I studied availability scenarios (in the graphs you can see cost and emissions):
a) Renewables are the main enablers of the cost (electricity for low SCC and gas for high SCC) and emission reductions.
b) Nuclear power has marginal climate and economic benefits (green line).
6) I did some robustness analysis (to cost and demand level uncertainties) to propose a robust social cost of carbon and it is 300€/tCO2, but I won't present it today.

🏁The End.

Feel free to join the session in which I will present: Concurrent session 131 - Gas Economics⬇️

🥁How can we unlock the capital flow toward the energy transition and how to ignite an affordable and just energy transition?
This is the question we try to answer in our latest @Deloitte Thought Leadership paper on Financing the Energy Transition
🧵[1/23]
deloitte.com/global/en/issu…
❓We first identify the key risks associated with the energy transition: macro risks, economic risks, technical risks and financial risks.
🧮We then quantify their impact on the cost of the projects, through cost of capital.
[2/23] Image
💡Of course there exists a huge set of de-risking instruments to mitigate these risks partially or fully, through systemic de-risking tools or to transfer them to entities that can bare them, via project-specific de-risking tools.

🚨New paper on the decarbonization of the European heavy-duty road transport sector, entitled "Climate neutrality in European heavy-duty road transport: How to decarbonise trucks and buses in less than 30 years?" in Energy Conversion & Management
🧵[1/12]
sciencedirect.com/science/articl…
Image
💻The modelling consists of coupling a detailed European energy system optimization model (DARE), with endogenous transport demand-side models: a logistics optimization model for freight segments, an inter-modality model for buses and coaches and a driver training model.
[2/12] Image
📽️We define 3 scenarios: High Electrification (HE), Hydrogen Hype (HH) and Enhanced Efficiency (EE). All share the same climate targets and existing policy on charging point developments, but they vary on the ambitions on electrification, hydrogen uptake and efficiency 👇

📢Check out our new paper on the importance of methane leakage on the role of natural gas in the European energy transition published in @NatureComms with our colleagues from IFPEN, Carbon Limits and SINTEF 👇
🧵[1/6]
nature.com/articles/s4146…
🧮In this study, based on an innovative modelling framework coupling energy system modelling, global hydrogen trade modelling and methane footprint module, we assess different methane abatement strategies and their energy transition implications.
[2/6] Image
📝We define three natural gas methane leakage abatement scenarios:
CEF: Current emission factors (no effort on methane abatement)
HP: Harmonized pledges (based on the announced policies and pledges)
BAT: Best available technologies (the strict maximum of methane abatement)

📢Check out our new publication in Energy Policy with @pquirion1.

💡In this paper we study the economic performance of different off-grid low-carbon hydrogen supply options coupled with a power system investment and dispatch optimization model.
(1/14)🧵
authors.elsevier.com/a/1hRU714YGgpc…
💻We model off-grid electrolyzers connected to offshore and onshore wind, solar and nuclear power plants connected to electricity system. The plants can either sell electricity to the grid, or produce hydrogen. We also add possibility of blue hydrogen production (ATR+CCS).
(2/14) Image
⚠️Electrolyzer lifetime depends on its number of hours of functioning, rather than years of use. But it is not possible to model in linear programming. So, we develop a simple (but robust) iterative framework to distinguish between different electrolyzer installations 👇

📢 Check out our new @Deloitte clean hydrogen outlook, where we discuss its decarbonization role, the demand and its production routes, the underlying trade organisations and economic implications:
"Green hydrogen: Energyzing the path to net zero"
🧵
[1/5]
deloitte.com/global/en/issu…
📃My key takeaways:

1️⃣Clean hydrogen demand can reach almost 600MtH2/year by 2050, becoming one of the key decarbonization pillars,

2️⃣While blue hydrogen can can be useful for the development of clean hydrogen economy, the future is green (more than 500MtH2/year by 2050),
[2/5] ImageImage
3️⃣Green hydrogen can also become an important element to bring significant export revenues and create skilled jobs in the emerging economies,

4️⃣Export revenues from green hydrogen trade can offset declining revenues from fossil exports,

En fait, si.
Le profil de l'énergie éolienne est disponible en ligne. Vous pouvez voir qu'en somme les éoliennes produisent plus en hiver que les autres saisons.
Bien-sûr qu'il y a quelques périodes anticycloniques, avec très peu de vent. Mais les énergies renouvelables sont/
nombreuses. On parle d'un mix avec une part élevée d'énergies renouvelables et non d'une seule et unique technologie. Il y a du solaire, hydro et biogaz/biomasse, des options de stockage etc.
Il y a d'ailleurs une très bonne complémentarité entre éolien et solaire. Vous pouvez/
voir cette complémentarité sur 18 années météo pour un système 100% renouvelable dans notre article 👇
Les périodes anticycloniques ne sont que d'1/2 semaines par hiver, et peuvent être traversées avec les autres renouvelables et les options de stockage
