    1. Doubling uptake of wind and solar power could set up Australia for net zero emissions by 2040

      Doubling uptake of wind and solar power could set up Australia for net zero emissions by 2040

      Australia could wipe out 80% of its greenhouse gas emissions – all of those from fossil fuel energy – in two decades by doubling the pace at which solar and wind power is being rolled out, academic analysis suggests. Australia installed about 7 GW of renewable energy in 2020, continuing a trend in which new clean energy generation roughly equivalent to that produced by a large coal-fired plant is added each year. Under this calculation, the country would have a near 100% clean electricity grid – backed by stronger long-distance transmission, battery and pumped hydro storage and demand management programs.

      How Siemens Energy Is Targeting the US Green Hydrogen Opportunity

      Green hydrogen is both an untested and a potentially vital way for renewable-energy-powered grids to store their intermittent power for later use, not just for hours at a time, but for days, weeks or even seasons ahead. Most of the early-stage work on hydrogen’s grid storage potential is happening in Europe and Asia, but the U.S. does have a few projects taking steps toward proving out the concept. On Monday, Siemens Energy announced a U.S. Energy Department grant-funded project to study how its Silyzer electrolyzers could be combined with hydrogen compression, storage and power plant controls technology to meet those goals at Intermountain.

      Plus Power Breaks Open Market for Massive Batteries in New England | Greentech Media

      Battery plants have established themselves in the sunny Southwest, but this week was the first time they won big in New England. San Francisco-based developer Plus Power won two bids in the latest capacity auction held by the New England ISO, which operates the transmission grid and competitive power markets in six Northeastern states. That means that these two battery plants offered a compelling enough price to edge out some fossil fuel plants for delivering power on demand. And they did it without any help from federal tax credits because none of them apply to standalone batteries.

      To batteries and beyond: The storage technologies poised to play a key role in the energy transition

      At least 33 U.S. utilities are aiming to become carbon-free or reach net-zero emissions by 2050. These are some of the technologies that could help them get there.

      By the end of 2019, approximately one out of three Americans lived in a state or community that has committed to or achieved 100% clean electricity, and experts say that getting to these ambitious goals will require large amounts of storage to smooth out electricity supply on a renewables-heavy grid.

      Utility Dive has collected four articles highlighting the following technologies: hydrogen, pumped hydro, battery chemistries other than li-ion, and compressed air and liquid air energy storage.

      North Sea Rocks Could Act as Large-Scale Underwater Renewable Energy Stores, Study Finds

      Rocks at the bottom of the North Sea may provide the perfect storage location for renewable energy, according to a new study. Excess power could be stored in the form of compressed air inside porous formations on the seabed, providing a reservoir that can provide energy on demand. This pressurized air can be released to drive a turbine, generating a large amount of electricity. This would allow green energy to be stored in summer and released in winter, when demand is highest.

      Solar + Storage Half The Cost Of Gas Peaker Plants — 8MinuteEnergy

      S&P Global reports the cost of solar with battery backup dropped precipitously in 2018. Several tenders for solar plus storage came in at under $30 per megawatt-hour last year. Stand alone prices for installed battery storage — based on a 20 megawatt-hour system with 4 hours of storage — dropped 40% from the previous year to $357 per kilowatt-hour and are expected to keep falling. Bloomberg New Energy Finance projects a further 52% reduction by 2030. Such tumbling prices have led Wood Mackenzie to forecast that as the market for solar plus storage matures, it could put more than 6,400 MW of new natural gas-fired peaking capacity in the US at risk by 2027.
