Natural Resources Canada, a federal agency, recently announced C$29.8 million of funding for Halagonia Tidal Energy, a subsidiary of DP Energy, to develop a 9-megawatt tidal array demonstration project — among the largest ever built — off the coast of Nova Scotia.

Why it matters: This funding announcement marks a win for tidal energy, indicating strong confidence in the technology and its potential to meet future energy needs. Internationally, marine energy has been slow to reach widespread commercialization in comparison to other renewable technologies like wind and solar, but demonstration projects such as these reduce the technology's risk and improve investor confidence.

The details: The project will include five Andritz Hydro 1.5-megawatt turbines and one SR2-2000 floating tidal turbine manufactured by Scotrenewables. Both turbine types have already demonstrated themselves in the water. Three of the Andritz Hydro turbines were deployed at the Meygen Tidal Array in Scotland, one of the first commercial tidal arrays in the world, and has produced over 8.2 gigawatt-hours. Scotrenewables has thoroughly tested a pre-commercial unit that has produced more than 3 gigawatt-hours for the electrical grid in Orkney, Scotland. This next iteration of the Scotrenewables device will be the largest tidal turbine ever constructed with a rating of two megawatts.

What's next: The project will be developed on the Bay of Fundy at the Fundy Ocean Research Center for Energy, a pre-permitted and grid-connected test site that also comes with a 15-year feed-in tariff. The Bay of Fundy is renowned for its extreme tides, in some places exceeding 10 knots, making it an excellent (possibly even too-energetic) site for tidal energy generation.

David Hume is a contractor supporting the marine renewable energy portfolio at the U.S. Department of Energy's Water Power Technologies Office and the founder of The Liquid Grid. The views expressed are his own.

The Biden administration is "deeply concerned" by new intelligence — detailed for Axios and other outlets — showing Russia stepping up preparations to invade Ukraine as soon as early 2022.

Why it matters: Most of this was known from public sources and satellite imagery, but the administration is sending a stronger signal by releasing specific details from the intelligence community.

CNN fires Chris Cuomo

CNN said Saturday evening it has fired one of its star anchors, Chris Cuomo, following new revelations from a legal review made by the company into Cuomo's involvement in the management of his brother's sexual harassment scandal.

Why it matters: Saturday's firing speaks to how much pressure CNN was under by employees and critics to address Cuomo's behavior.

Electric car prices could go up before they come down

The secret to affordable electric vehicles is cheaper batteries. But after years of falling prices, battery costs are now headed in the wrong direction.

Why it matters: Costlier batteries could drive up the price of electric vehicles — threatening the auto industry's transition away from fossil fuels, and, in turn, society's fight against climate change.
