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.

Senate Armed Services chair dismisses Trump threat to veto defense bill

Sen. Jim Inhofe (R-Okla.), chair of the Senate Armed Services Committee, told reporters Wednesday that he plans to move ahead with a crucial defense-spending bill without provisions that would eliminate tech industry protections, defying a veto threat from President Trump.

Why it matters: Inhofe's public rebuke signals that the Senate could have enough Republican backing to override a potential veto from Trump, who has demanded that the $740 billion National Defense Authorization Act repeal Section 230 of the Communications Decency Act.

Scoop: Uber in talks to sell air taxi business to Joby

Uber is in advanced talks to sell its Uber Elevate unit to Joby Aviation, Axios has learned from multiple sources. A deal could be announced later this month.

Between the lines: Uber Elevate was formed to develop a network of self-driving air taxis, but to date has been most notable for its annual conference devoted to the nascent industry.

Setting the Biden-era cybersecurity agenda

The Biden administration will face a wide array of cybersecurity challenges but can take meaningful action in at least five key areas, concludes a new report by the Aspen Cybersecurity Group.

Why it matters: Cybersecurity policy is a rare refuge from Washington's hyperpartisan dysfunction, as shown by the recent work of the bipartisan Cyberspace Solarium Commission. President-elect Joe Biden should have a real opportunity to make progress on shoring up the nation's cybersecurity and cyber capabilities without bumping up against a likely Republican-controlled Senate.
