*Metal decarbonization* is essential for deep decarbonization. Electrolysis is an elegant solution and is now being pursued for decarbonizing ironmaking and other industrial processes. However, aluminum is already electrolytic and is still stubbornly CO2 intense. Why? 🧵(1/19)

Thread: Each week I run a simulation of Australia’s main electricity grid using rescaled generation data to show that it can get very close to 100% renewable electricity with just 5 hrs of storage (24 GW / 120 GWh) Results: last week: 100% RE last 118 weeks: 99.0% RE (1/4)

Hydrogen: Hype, hope, or hard work? The Grattan Institute explores the best vs worst use cases for green H2: ✅ feedstock for ammonia ✅ steel ✅ alumina ❌ light vehicles ❌ gas replacement in homes 📒 Report: grattan.edu.au/report/hydroge… #EnergyTransition #renewables #hydrogen

It's here: my annual presentation on decarbonization. There is a lot going on, and I attempt to capture it in 200 slides. Ocean heat content, deforestation, fund performance, vehicle efficiency, lighting technology, GLP-1 agonists, and much more. nathanielbullard.com/presentations

I’m speaking about the energy-water nexus at this AWA association event on 15 Feb in Adelaide. Let me know what you’re curious about! SA folk with an interest in the water and/or energy sector, hope to see you there. awa.asn.au/upcoming-event…

World's largest EV battery maker says prices in 2024 will drop 50% to $56/kWh This is gargantuan - and will accelerate EV cars, trucks, trains, ships, planes and BESS Sit back and watch oil running for the exit by 2030 (chart via RMI) thedriven.io/2024/01/25/wor…

New first-of-its-kind analysis from International Energy Agency shows the major contributions clean energy is making to the world economy In 2023, it accounted for 10% of global GDP growth, adding around $320 billion to economic output Learn more in our new commentary ➡️ iea.li/4d2594b

🚨 BNEF’s New Energy Outlook 2024 shows the window to reach net-zero emissions by 2050 is rapidly closing. There's still time for the world to get on track – if decisive action is taken now. Failure to do so risks putting even a 1.75C global warming target out of reach.

This is one chart that stood out for me from BloombergNEF's NEO. A few quick thoughts: 1/

What’s going on with lithium-ion battery prices? In short, they’re plummeting, and the implications are just starting to ripple out across the automotive and power sectors. A short thread:

⚡️🚘BREAKING: For the first time ever, more than half of cars sold in China last month were electric New-energy vehicles, including EVs and PHEVs, reached a record-high 51.1% of retail sales in July, according to data from the China Passenger Car Association EVs are already

How are energy markets like a tandem bike? How do they have to change to accommodate increasing renewables as part of the energy transition? Great explainer from Ian Berryman and Helen Kou from BloombergNEF #renewables #energytransition podcasts.apple.com/au/podcast/swi…

Congratulations to Mike Cannon-Brookes 👨🏼‍💻🧢🇦🇺, who just received government approval to build the world's largest renewable and storage project. Sun Cable is a preposterously large (24GW+) solar and wind farm plus an improbably long electricity cord. reneweconomy.com.au/sun-cable-plib…

Energy transition investment topped $1.8 trillion in 2023 says BloombergNEF. Much of this is driven by renewable energy and electric vehicles so far. But grid investments, electrified heat, industry decarbonisation and nuclear are also picking up steam.

THREAD My deep dive on International Energy Agency #WEO24 🌄Solar up 4x by 2030, top ⚡️ source by 2033 🥇Clean energy +44% by 2030, top *energy* source by "mid-30s" 🛢️EVs displace 6mb/d by 2030 (⏫4mb/d last yr) ⛰️Fossil fuels peak by 2030 🌡️Warming 2.4C(🔽 2.6C 2021 ⏬ 3.5C 2015)

Will solar PV soon be the cheapest source of electricity in most places around the world? This Nature Communications paper says yes. Most surprisingly this is AFTER including short- and long-term storage costs for renewable energy sources. nature.com/articles/s4146…
