Work has started on a pioneering green hydrogen production plant in Chile that is backed by global giants including Enel and Siemens Energy and will help development of e-fuels by Porsche.

A machine capable of removing 4,000 tons of carbon dioxide from the air each year has just been switched on in Iceland. The plant – named Orca, after the Icelandic word for "energy" – is the largest carbon removal facility in the world, converting emissions into minerals that can be permanently stored deep underground.

A key U.K. power cable knocked out by a fire will stay partly offline until March, National Grid Plc said, deepening the energy crisis threatening Britain as it heads into winter.

Climate Week is kicking off Monday in New York City and major companies including Amazon and Microsoft as well as Bill Gates’ Breakthrough Energy are sharing news of their efforts to decarbonize.

In Iceland's barren landscape, a new container-like structure has risen alongside plumes of steam near the Hellisheidi geothermal power plant. Its job is to undo some of the damage carbon-dioxide (CO2) emissions are causing to the planet. The facility, called Orca and built by Swiss startup Climeworks AG, will suck CO2 out of the air. Icelandic startup Carbfix will then pump it deep into the ground, turning it into stone forever.

The majority of the built environment that will exist in 2050 already exists today. These buildings account for approximately 28% of total global carbon emissions, according to a recent report from the UN Global Alliance for Buildings and Construction. This means a city’s key challenge is not how it will build new “net zero” infrastructure – which is “relatively easy” – but how it will decarbonise infrastructure that was built long before climate change was a key driver.

Grid parity, resilient networks and strategic partnerships have spurred growth in the world’s solar panel manufacturing capacity in recent years, to 330 gigawatts (GW) in mid-2021. According to Norway-based independent energy research and business intelligence company Rystad Energy, to meet the 1.5°C 2050 scenario under the Paris Agreement, capacity has to quadruple to 1,200-1,400 GW by 2035 to handle the peak installations needed.

A New Zealand investment firm is funding the launch of a renewables company in Singapore with the aim of riding the wave of climate action in a region under growing pressure to transition to clean energy.

Renewable energy developers will compete for a share in a £265m subsidy pot as the government aims to support a record number of projects in the sector through a milestone subsidy scheme later this year. Under the scheme, offshore wind developers will compete for contracts worth up to £200m a year, and onshore wind and solar farms will be in line for their first subsidies in more than five years.

By tapping into an unexpected energy source, wooden flooring, researchers from Switzerland have developed an energy-harvesting device that uses wood with a combination of a silicone coating and embedded nanocrystals to produce enough energy to power LED lightbulbs and small electronics.

Solar panels are no longer a rarity in Singapore. The Government plans for solar capacity to quadruple to 1.5 gigawatt-peak (GWp) by 2025, before rising to 2 GWp by 2030. This would meet about 4 per cent of Singapore’s current electricity demand.

Brazil's Mines and Energy Minister Bento Albuquerque on Tuesday warned that the country's energy crisis was worse than previously thought, as a record drought hampers hydropower generation.
