The Energy Department's Pacific Northwest National Laboratory and its partners are calling for academic and private collaboration in its Development of Integrated Screening, Cultivar Optimization and Verification project, which aims to identify the algae strains best suited for manufacturing bioproducts and biofuels. The project, which also hopes to lower the cost of bioenergy production from algae feedstocks, will review proposals on a rolling basis.
A waste-to-energy plant in Copenhagen features a green, artificial ski slope on its rooftop. Once complete, the building will feature hiking trails, a park and a climbing wall -- all designed to maximize the building's potential utility.
York, Maine, is pursuing its green city goals in part by creating a sustainability fund and quantifying the town's energy usage and emissions. Recommendations under consideration to reduce the city's carbon footprint include switching to electric municipal vehicles and building a solar farm over an abandoned landfill.
The 780-mile Grain Belt Express transmission project may come to fruition under the leadership of new owner Invenergy. "We do bring resources that Clean Line didn't bring to the table," says spokesperson Beth Conley, noting that pending regulatory approval, the project could increase access to low-cost wind and eliminate transmission bottlenecks.
Lawmakers in Oklahoma are considering a pair of bills that would create a new tax for wind production and eliminate tax credits that some companies based project decisions on. The latter bill is retroactive and could create business uncertainty in the state, says Wind Coalition Oklahoma Director Mark Yates.
Offshore wind and related supply chain projects may be the next big thing for North Carolina's economy, says Southeastern Wind Coalition President Katharine Kollins. The state's 18-month moratorium on new land-based wind projects has also ended, but the measure's reinstatement remains a concern for companies.
Companies brought 24.9 gigawatts of new installed land-based wind capacity online in the Asia-Pacific region last year, according to the Global Wind Energy Council. China accounted for 21.2 GW of the new capacity.
Researchers have successfully used an artificial intelligence-based system dubbed WaveletFCNN to identify patterns that indicate the presence of potentially damaging ice on turbine blades. Companies could start mitigation efforts earlier if they were aware of the presence of ice, the researches wrote in a paper.
Researchers in Hawaii are exploring wind energy, tidal and other technologies to help the state meet its 100% by 2045 goal for renewables. "We definitely think of Hawaii as a 'postcard from the future' as to how renewables will attach to the grid," says Andy Hoke, a senior engineer at the National Renewable Energy Laboratory.
Wisconsin Gov. Tony Evers will become part of the US Climate Alliance, a coalition that upholds the Paris climate accord's goal to limit greenhouse gas emissions. "Gov. Evers is showing the nation that he intends to lead on climate action, and we look forward to working with the governor on his priorities like investing in transportation infrastructure, locally produced renewable energy, and natural and working lands across the state," Executive Director Julie Cerqueira says.
