Electric vehicle revolution puts pressure on energy grid

Solar car is better option.

The influx of electric vehicles into Australia could put an additional load of 20 gigawatts a day — or a doubling of peak electricity demand — on the electricity grid by 2030 if most owners charged up at the same time every night, a new report has found.

The $350 million research collaboration between industry, universities and government has identified a raft of challenges for the arrival of EVs which are expected to make up 80 per cent of new vehicles sales by the end of the decade, making up almost 25 per cent of Australia’s total car fleet.

While there will be huge benefits from taking petrol-guzzling cars off the road, the arrival of EVs – which need to be charged either at home or at public charging stations – creates a range of new headaches, not the least for the electricity grid.

Mobile H2O generator pulls drinking water from air for off-grid nomads

For over a decade, Israeli atmospheric water generator (AWG) company Watergen has been one of the players working to refine and grow air-to-water technology that can efficiently pull water vapor out of the air and collect it as fresh, filtered drinking water. Its previous work has focused heavily on large installations to supply communities, businesses and households, and its latest innovations shrink the water-harvesting tech into a form portable enough for overlanders, RVers, tiny home dwellers and other off-grid explorers.

The last time we ran into Watergen’s work was at CES 2,019 where it showed the Automotive AWG system. The center-console-integrated system was one of the wondrous highlights of the show, but it seemed an odd, limited use for a technology with such potential, a strange detour on a larger journey. Does the average passenger car driver really need a water tap over the cupholders?

If a mobile air-to-water generator is to find a following amongst drivers, it would be a far better fit for vehicles that spend long hours traveling through places without much access to water – motorhomes and camping trailers, specialized remote-work trucks and vans, and perhaps long-haul tractor-trailers, to name a few examples.

Wright proposes a 100-seat electric airliner powered by aluminum

US-based Wright Electric has announced a 100-seat electric short-hop aircraft slated to go into service by 2026. It’ll either be powered by hydrogen, or it’ll use recyclable metal in what the company calls an “aluminum fuel cell.”

Wright is working on a number of large electric aircraft projects, including an even bigger 186-seater it’s developing in conjunction with European airline EasyJet and BAE Systems. This would be a “low-emissions” electric, presumably using a fossil-fueled range extender to top up its batteries and extend its flight range to around 1,290 km (800 miles). The partnership is pitching it as a “path” towards clean aviation, a kind of Prius of the skies, that will prove the electric powertrain while waiting for energy storage to come up to scratch.

Wright’s latest project, however, will be totally zero-emissions, and will use high-density energy storage to tackle flights up to an hour in duration – that’s enough for the ~1,000-km (620-mile) hop between Sydney and Melbourne, or London-Geneva, or Tokyo-Osaka, or LA-San Francisco.

The World’s Largest Floating Solar Power Farm Is Now Open In Thailand

With 145,000 panels.

The world’s largest floating solar farm has now begun operations at the Sirindhorn Dam on the Lam Dom Noi River in Thailand. The dam has a capacity of generating 45MW of power using its solar panels, the Electricity Generating Authority of Thailand (EGAT) confirmed in a press release.

The news comes after the country started advancing its carbon neutrality goals by 15 years. At the United Nations Climate Change Conference being held in Glasgow, UK, Thai Prime Minister Prayut Chan-o-cha pledged that his country would attain carbon neutrality by 2,050 much ahead of the earlier set target date of 2,065 local media reported. The announcement is a major move considering that two-thirds of Thailand’s current power generation is sourced from natural gas.

Chile aims to become leader in green hydrogen

Several countries are now leading the world in producing sustainable energy sources.
One of them is Chile, which has set its sights on becoming a leader in producing green hydrogen.
Many believe it could be a solution to replacing fossil fuels at a competitive price.

Biochar Carbon Capture And Storage. Lower CO2 & Cleaner Environment To Better Crops & Lower Costs

Carbon is not our enemy, but the system is out of balance. Too much as atmospheric gases and too little in the ground and soil in the simplest terms.

Biochar, although not new, has found a new lease of life. A process that generates heat, uses waste, locks away carbon and benefits almost every system to which it is introduced.

After reading it all about it, I just had to share the possibilities and so I compiled what I learnt into a short video for those interested.

Hope you enjoy and have a great day.

Biochar Carbon Capture And Storage.
