Swedish Group Moves Ahead With World’s Largest Single Offshore Wind Project

June 28, 2022

Swedish-based renewable energy developer OX2 has taken another step toward construction of its Aurora offshore wind farm, a 5.5-GW project sited between the islands of Gotland and Oland in the Baltic Sea.

OX2 on June 27 announced it had submitted a permit application to build the wind farm under the auspices of Sweden’s Exclusive Economic Zone. Aurora, still in an early development stage, is part of OX2’s 11.7-GW project portfolio for Sweden. Aurora at present is considered the largest single offshore wind farm under development worldwide; Ørsted’s Hornsea project off the UK coast in the North Sea has 7.5 GW of total capacity, but that installation includes four separate wind farms.

“This is the next step to realize the Aurora wind farm,” said Hillevi Priscar, country manager for OX2 in Sweden. “Together with our other planned offshore wind farms it constitutes a significant part of the electricity production Sweden needs, to reach the climate targets and to secure the production and energy independence of Sweden.”…

China Group Develops Plan to Turn Biomass Into Low-Carbon Natural Gas

Researchers in China have published the results of a study that the group said provides an efficient catalytic approach to directly transfer solid biomass into natural gas, while enabling the gas to have a low-carbon footprint.

The researchers said bio-natural gas produced from the hydrogen combined with lignocellulosic biomass could be used at power plants, and would have applications for transportation and other industries. The group said it could be transported using existing pipeline infrastructure.

China’s Biomass Energy Industry Promotion Association (BEIPA) last year reported that the country annually produces more than 900 million tons of agricultural and forestry biomass. BEIPA officials said the biomass could generate power equal to that from about 400 million tons of coal, and said the figure is higher when including organic waste from urban and rural areas.

The study, supported by several entities including the Natural Science Foundation of China and published in January by the scientific journal Nature Communications, provides what the group calls new guidance for the catalytic transformation of raw biomass.…

A digital mining company has an agreement to purchase a second power plant in Pennsylvania, as the group increases its coal refuse reclamation operations in the state to provide energy for its bitcoin mining operations.

Stronghold Digital Mining, a bitcoin (BTC) miner headquartered in Kennerdell, Pennsylvania, on Aug. 3 said its purchase of the Panther Creek Plant, located on 33 acres in Nesquehoning, in Carbon County, adds 80 MW of generation capacity to its portfolio, which also includes the 85-MW Scrubgrass plant. Scrubgrass is located on 650 acres in Scrubgrass Township, in Venango County.

Stronghold, founded earlier this year, uses the power plants to convert coal refuse into power that is used to mine bitcoin, an energy-intensive process. Coal refuse is classified by Pennsylvania as a Tier II alternative energy resource, akin to large-scale hydropower. Coal refuse over the years has been left in piles near coal operations; today, circulating fluidized bed technology allows for emissions-controlled conversion of coal refuse into energy.…

The post Group Says It Will Launch World’s Largest Green Hydrogen Project appeared first on POWER Magazine.

Global energy company SGH2, part of Washington, D.C.-based Solena Group, said it has a deal with Lancaster, California, to build what the company calls the world’s biggest green hydrogen production plant, set to be in full operation in early 2023.

The company on May 20 said the plant will feature SGH2’s technology that uses recycled mixed paper waste to produce “greener than green” hydrogen. SGH2 said its process “reduces carbon emissions by two to three times more than green hydrogen produced using electrolysis and renewable energy, and is five to seven times cheaper.” The deal with Lancaster, first announced Tuesday, noted that SGH2 makes hydrogen with a plasma heating technology, originally developed for NASA, that will disintegrate recyclable materials at temperatures as high as 7,000F.

The company said its green hydrogen is cost competitive with so-called “gray” hydrogen produced from fossil fuels like natural gas, which comprises most of the hydrogen used in the U.S.…
