[ad_1] Photo: GM GM has a new suite of energy products that allow you to share power between your car and your home, and we got to see them in action. GM invited us to a swanky house in Beverly Hills to demonstrate its new home energy products, including vehicle-to-home (V2H) backup power that allows you to power your house off of your EV battery. These products include its new bidirectional EV charger, which it’s calling the GM Energy Powershift Charger ($1,699), and the GM Energy V2H Enablement Kit ($5,600) which comes with AC-DC inverter, Home Hub (the computer which manages loads through the house), and dark start battery (provides a small amount of power as the system starts up and shifts from home to vehicle power). The systems can be bought separately or bundled together for $7,299. Installation is separate (and costs can vary widely), and GM has partnered with Qmerit, a national EV charging installation company, to make it easier for customers to find an installer. GM set up its system and brought …

Invisible ‘dark radiation’ may explain a big problem with dark energy

Invisible ‘dark radiation’ may explain a big problem with dark energy

[ad_1] A slice through the largest 3D map of our universe to date laire Lamman/DESI collaboration There are hints that the universe may be behaving unexpectedly, and astrophysicists are racing to explain why. Their ideas to account for the surprising result include allowing dark matter and dark energy to interact, and arguing for the existence of strange “dark radiation” that is similar in nature to regular light but invisible. In April, researchers using the Dark Energy Spectroscopic Instrument (DESI) in Arizona released the biggest 3D map of the universe ever created, and it hinted… [ad_2] Source link

[ad_1] The mid-ocean ridge is where the Earth creates its outer skin. It’s called the boundary of creation. We knew there was life on the bottom of the ocean but not entire ecosystems supporting large animals until our expedition went down there in 1977. First, we sent down an unmanned vehicle called Angus, which was essentially a camera system and strobe lights within a two-tonne steel cage. It was going down in the eternal darkness, slaloming back and forth like a skier down a mountain. We were exploring the longest mountain range on Earth – the mid-ocean ridge. We were looking for heat, and we theorised that there would be vents in the ridge, but we never expected to see large concentrations of life. After 12 hours of taking thousands of photos, Angus came back up. When we studied the photos we found that at about 2,500 metres deep, where we had detected a sudden increase in temperature, the water got cloudy. Then we suddenly saw clams – giant clams the size of dinner plates …

Crawley’s Bramble Energy completes £1.8m hydrogen fuel cell project

Crawley’s Bramble Energy completes £1.8m hydrogen fuel cell project

Published by skeptic

[ad_1] Bramble Energy, a cleantech firm focused on hydrogen fuel cell technology, has completed a project aimed at accelerating the UK’s transition to an electrified automotive industry. In 2022, the company was awarded £1.8 million via the Advanced Propulsion Centre (APC)’s Scale-up Readiness Validation (SuRV) programme to develop an optimised fuel cell stack assembly with the capacity to produce up to 2,000 50 kW stacks a year. This has now been successfully achieved at Bramble Energy’s HQ and hydrogen innovation hub in Crawley, where the team have managed to simplify the fuel cell stack assembly process through the design of their trademarked Printed Circuit Board Fuel Cell (PCBFC). The successful project follows the company’s contribution last year to the Hydrogen Electric Integrated Drivetrain Initiative (HEIDI), which saw it provide fuel cell technology for a new hydrogen-powered double-decker bus. Dr Tom Mason, CEO of Bramble Energy, said: “In our efforts to help both the automotive and public transport industry find a clean, reliable and cost-effective way of powering vehicles, both the SuRV and HEIDI projects have …

Geothermal industry looks to tap oil and gas workers to expand renewable energy

Geothermal industry looks to tap oil and gas workers to expand renewable energy

Published by skeptic

[ad_1] BOISE, Idaho — A U.S. Department of Energy report this spring made a bold prediction. The nascent geothermal industry, it said, has a ready workforce of 300,000 engineers, hydrologists, drillers and power plant operators ready to tap right here in this country. All that’s needed are more early adopters like Tina Riley who are willing to move over from the oil and gas sector. After two decades as a geologist with ExxonMobil in Houston, she recently moved to Idaho to help run Boise’s geothermal utility. “Boise is really well known for geothermal and I wanted to become part of it,” Riley says. “I really wanted to be part of the energy transition.” Geothermal energy, which in its simplest form means tapping hot water locked in granite faults sometimes thousands of feet below the surface of the earth to create heat or electricity, is often dubbed an invisible technology. It’s long been seen as underutilized. But it’s also a hugely expensive renewable resource to extract compared to more conventional drilling. Nevertheless, the White House is …

Renewable energy parks will speed progress towards net zero

[ad_1] Co-location is a more efficient way to generate electricity. Solar and wind energy complement each other’s generation patterns both seasonally and daily, with solar panels producing electricity during the day and wind turbines operating more consistently throughout the day and night. They also help equalise production throughout the year, with stronger winds in the winter and more sun in the summer. For example, adding four 4MW wind turbines to an average-sized 50 MW solar site, would increase green energy production from around 50,000 MWh annually to over 100,000 MWh, effectively doubling the delivery of home-grown clean energy on a single site. Further, efficiently producing energy in areas close to where it will be used, reduces the need for costly and inefficient long-distance transmission, making co-location especially productive in highly-populated regions.

Clean energy on the cusp of rolling back fossil fuels: Report | Climate Crisis News

Clean energy on the cusp of rolling back fossil fuels: Report | Climate Crisis News

Published by Sam

[ad_1] Renewable energy will this year shrink fossil fuels’ reigning share of the global electricity market for the first time. That is the key finding of Ember, a leading energy think tank based in London, which on Wednesday published its first comprehensive Global Electricity Review analysing data from 215 countries. Thanks to the galloping pace of new solar and wind capacity, renewables have been claiming almost all growth in electricity demand for five years, leaving fossil fuels stagnant. But this year, said Ember, they will also roll back fossil fuels’ market share by 2 percent – the beginning of a decade-long process of knocking them out of electricity production altogether in three dozen developed economies. Renewables expanded by an average of 3.5 percent a year during the past decade, compared with an annual 1.5 percent in the previous decade, as prices for photovoltaic panels and wind turbines climbed down and their productivity soared. Ember found that the world already produced a record 30 percent of its electricity from carbon-free sources last year. Several additional factors …

Russia Hits Ukrainian Power Plants, Further Straining Energy System

Russia Hits Ukrainian Power Plants, Further Straining Energy System

Published by Sam

[ad_1] A large Russian missile and drone assault caused serious damage to several power plants across Ukraine early Wednesday, Ukrainian officials said. It was Russia’s fifth attack on energy facilities in the past month and a half, part of a broader campaign aimed at cutting off electricity to swaths of the country and making life miserable for civilians. Ukraine’s largest private electricity company, DTEK, said in a statement that three thermal power plants had been hit, further straining Ukraine’s electricity generation capacity, which was already reeling from previous assaults. The company said that 80 percent of its available generating capacity had been damaged or destroyed by the recent attacks. Ukrenergo, Ukraine’s national electricity company, said that it might have to cut power to some domestic and industrial customers on Wednesday evening as a result. “You have to be prepared for this,” Volodymyr Kudritskyi, the head of Ukrenergo, told the Ukrainian news media. The attacks have hit Ukraine at a particularly difficult moment. The country is facing a shortage of air defense weapons and ammunition amid …
