America continues to fund MHK development as part of new water energy resources

The U.S. Energy Department yesterday announced it will fund up to US$12 million to support four projects that will advance marine and hydrokinetic (MHK) energy technologies.

Also, earlier this month, the proposed federal budget unveiled — should Congress approve it — will lessen the blows many expected to be dealt to several hydroelectric power-related agencies.                                            

The $1.07 billion package is largely being hailed as a bipartisan win and would keep the federal government funded through the end of current fiscal year on Sept. 30.

Two projects will test and validate wave energy converter (WEC) prototypes in open water. The tests will demonstrate wave energy’s potential to compete with other forms of energy in the longer term. Two other projects will address important early-stage MHK technology development challenges. 

“Research and development in MHK technology will let America develop new water energy resources that can provide reliable electricity close to load — be it a remote village, major city, or distributed application, like forward-operating military bases or subsea data centers,” said Alejandro Moreno, director of the Water Power Technologies Office. “MHK also provides an opportunity to develop new energy markets and create jobs.”

The MHK projects are:

AquaHarmonics, grand-prize winner of the Wave Energy Prize that is based out of Oregon City, Ore., will seek to upscale its device while maintaining low costs.

Portland State University of Portland, Ore., will develop a multistage, magnetically geared generator with airtight casing to improve the cost, reliability, and efficiency of MHK devices. Increasing the gear ratio through the multistage design reduces the generator size, which in turn reduces the structural support required, thereby lowering costs. The magnetic gearbox, which creates speed change without physical contact, minimizes operations and maintenance costs and provides protection from overloading during extreme events.

The WEC projects are:

California Wave Power Technologies (CWPT), runner-up in the Wave Energy Prize, will upscale its WEC technology for open-ocean testing. Through testing, the Berkeley, California-based company will validate and update estimated costs for a full-scale version of its technology.

ReVision Consulting of Sacramento, Calif., will integrate wave measurements from radar and buoys to better predict ocean waves and provide data to WEC device controllers. Accurate wave-prediction technology can help WECs more efficiently convert energy from waves into electricity.
