At Potsdam Institute for Climate Impact Research PIK we are looking for Postdocs and PhD candidates to model and explore #circularity and #industry transformation scenarios of #energy -intensive industries (steel, cement, and plastics).

International team work with green and blue hydrogen, LCA and economic experts

Thank you!

Finally, low methane leakage rates are possible (see e.g. Norway); yet, policy makers need to take a life-cycle GHG perspective and price or regulate methane emissions when importing blue hydrogen&ammonia. Uncertainty and monitoring challenges will need to be resolved.

4. For low gas prices (~15€/MWh) there is a substantial competitiveness window for blue hydrogen, if produced with >90% CO2 capture and <1% methane leakage

Direct cost parity at ~2045, yet green hydrogen might have competitive edge <2045 due to slightly higher blue h2 emissions

1. To compete with natural gas, both green and blue hydrogen likely require substantial policy support until at least 2035 (in addition to carbon pricing).

Hydrogen will remain costlier than natural gas. CO2 pricing or emission regulation are needed also in the long term.

We quantify these fuel-switching points by combining progressive and conservative cases for green and blue hydrogen supply - as well as low and high gas prices.
(I know it is a complex figure: the legend explains the milestones)

Main results are...

Underlying economics: From the intersections of fuel-switching CO2 prices in time, we derive five fuel-switching points that capture the increasing competitiveness of green hydrogen with blue hydrogen. High residual emissions close the competitiveness window of bridging options.

Key insight: Blue hydrogen's residual emissions can close its competitive window earlier than direct cost parity with green h2 suggest. To compete, blue hydrogen i) needs to be clean (CO2 capture rate >90% and methane leakage rates <1%) and ii)gas prices need to be low(15 €/MWh)

How will green and blue hydrogen compete with natural gas and with each other?

New paper combines ranges for direct cost developments and residual emissions.
Importantly, CO2 & methane pricing or emission regulation will have an increasing impact.

ANU at COP28: now with a list of post-COP opeds, videos etc, in addition to video from ANU events at the conference. iceds.anu.edu.au/news-events/ne… ANU Climate, Energy & Disaster Solutions

Some of my initial takeaways from #COP28 - more to follow after the break

Looking for key takeaways from COP28?

Watch our post-COP video to hear insights from Frank Jotzo, Fiona J Beck, Mark Howden plus an update from Dr. Siobhan McDonnell during the conference as she was working to keep a fossil fuel phase-out agreement alive.

Great analysis on the #COP28 outcome from Frank Jotzo

COP28 - my initial take on energy decisions in the Global Stocktake, in The Guardian.
Recognition of need to 'transition away from' all fossil fuels is substantial progress, despite plenty of wriggle-room.

Our #SystemsEngineering teaching team has won a 2023 Vice-Chancellor’s Award for Excellence in Education. Their strategic pivot, undertaken four years ago, resulted in deeper engagement with industry, and a 13% improvement in student satisfaction.

Simon Stiell #COP28 #UniteActDeliver

Chris Bowen (paraphrased): phasing out fossil fuel emissions is not enough, we need to phase out fossil fuels. Abatement is a backstop to use when we have no other option, it is not an excuse to keep using fossil fuels. (also, lots of footy metaphors!) #COP28

👀👀👀

Given the just-leaked OPEC letter calling for a focus on 'emissions' rather than fossil fuels themselves, this retweet from the official #COP28 account is…interesting
