  • World’s first crewed solid-state flight electrifies aviation’s future

    Ooooh this is seriously cool The Helios Horizon’s previous lithium-ion pack delivered 260 Wh/kg (watt-hours per kilogram, a measure of how much energy a battery holds relative to its weight). The new solid-state cells hit 410 Wh/kg, a 60% jump. Chief test pilot and company founder Miguel Iturmendi expects that figure to grow another 40%…

  • This is what 21st C fuel security looks like

    The arrival of a purpose-built ship owned by Chinese car manufacturer BYD that docked in Melbourne on Sunday carrying 5000 vehicles has been described by an analyst as a turning point in the electrification of Australian road transport. The BYD Zhengzhou, one of a fleet of eight car-carrying ships owned and operated by BYD, normally…

  • Soaring solar and a surge in hydro push more coal off the US grid

    The slow inexorable decline of fossil fuels continues… and remains a sole bright spark. Given that renewable growth greatly exceeded demand, there was nowhere to go for fossil fuels but down. Overall, they saw a drop of about 3 percent year-over-year, with an absolute change similar in magnitude (if not sign) to the growth in…

  • How gophers brought Mount St. Helens back to life in one day

    A great example of how important soil biome is when it comes to regenerating native forests. … the scientists did not expect the benefits of this experiment would still be visible in the soil today, in 2024. A paper out this week in the journal Frontiers in Microbiomes details an enduring change in the communities of fungi…

  • Wind powers a record summer for renewable energy in Britain

    Gotta love down and to the right…. Before August 2024, monthly generation from fossil fuels had never dipped below 4 TWh, even during the lockdowns of 2020 when demand for electricity and transport fuels plummeted. What’s more exciting is that this was the first time fossil fuels (98.5% gas and 1.5% coal) fell to third…

  • Agrivoltaics come of age

    “Far from reducing food production, agri-PV actually increases yields for some crops,” says Ember analyst Paweł Czyżak. “Agri-PV combines the best of both worlds — electricity and food production, preserving precious land for agriculture, yet still enabling the energy transition to move forward, benefitting societies and economies.” https://theprogressplaybook.com/2024/09/10/agrivoltaics-come-of-age/

  • Batteries start to rival gas on California’s electricity grid

    Lithium batteries appear to be undercutting the use of fossil fuels. Gas accounts for 40% of California’s grid. However, its use in April registered its lowest proportion in seven years. “The data clearly shows that batteries are displacing natural gas when solar generation is ramping up and down each day in CAISO,” notes an analysis by Grid…

  • South Australia will enshrine 100% net renewables by 2027 target into law

    Home to the city of Adelaide, South Australia has already more than halved its emissions since 2005 thanks to a rapid shift to wind, solar, and battery technologies, which now meet around 70% of its annual power needs. By 2027, it must reach 100% net renewable electricity, though it’ll keep gas power plants on standby…

  • Christopher Luxon is gaslighting the country amid energy crisis – Chlöe Swarbrick

    They’ll tell you the oil and gas ban, which came into effect six years ago, is to blame. That wilfully ignores how, of the five oil and gas fields that already exist, it has taken an average of 16 years to go from exploration to production. It carefully curates out the fact that gas production…
