[Episode #155] – Marine Energy

Marine energy—a collection of diverse technologies designed to capture energy from the ocean in various ways—has languished far behind more mature renewable technologies like wind, solar, and geothermal energy for decades. The reasons for its slow progress are as diverse as the technologies themselves, but there are some indications that a few of these technologies have learned from the failures of the past, and are finally becoming mature enough to reach commercial scale. Should they succeed in doing so, they offer the tantalizing potential to provide virtually limitless amounts of clean power, 24x7, using a wide variety of applications—from power supplied by cable to onshore grids, desalination of fresh water, standalone devices operating out in the deep ocean, devices that can convert the electricity they generate into synthetic liquid fuels for transportation by ship, and carbon capture technologies.

But if we are to use the marine environment sustainably, we have to do so informed by solid scientific research into the impact our technologies will have on the marine environment and its wildlife residents. Our guest in this episode is one such researcher. An oceanographer by training, with deep expertise in the environmental effects of wave and tidal energy and offshore wind installations, Dr. Andrea Copping leads a team at the Pacific Northwest National Lab (PNNL) in Richland, Washington which integrates laboratory, field, and modeling studies into a coherent body of evidence to support siting and consenting decisions. She also leads OES-Environmental, an international project on environmental effects of marine energy development around the world, under the auspices of IEA Ocean Energy Systems.

Join us in this wide-ranging discussion about the many different forms of marine energy, and how some of them might yet emerge as major players in the portfolio of energy transition solutions.

[Episode #154] – Japan’s Nuclear Dilemma

Japan was once the third-largest operator of nuclear power facilities in the world, but that came to a sudden end with the largest earthquake to ever hit the country on March 11th, 2011, which caused a massive tsunami that led to the meltdown of the Fukushima Daiichi nuclear power plant, and then to the closure of all 54 of the country’s nuclear plants. In the decade hence, Japan has struggled to plot a new course to get its energy, see-sawing between attempts to restart the plants and relying more on coal and natural gas, while at the same time trying to improve efficiency, conserve energy, and find ways to reduce its emissions to help meet its decarbonization targets under the Paris climate agreement.

Now, the country’s leadership is taking bold steps toward building more renewables and seeking to cut back on its use of fossil fuels, while just a handful of its nuclear plants have been restarted and the future of the rest is very much in contention. It’s a confusing political landscape, and one of the most challenging cases in the world for energy transition, but it also could prove to be one of the most cutting-edge leaders, especially if it can exploit its offshore potential for renewables.

In this episode, Bloomberg reporter Stephen Stapczynski, who has reported on Japan’s energy sector for years, paints for us a coherent picture of Japan’s nuclear past, where it stands now, and how it will obtain its energy in the future.

[Episode #93] – Energy Transition in India and Southeast Asia, Part 2

This is Part 2 of our two-and-a-half hour interview with Tim Buckley, of the Institute of Energy Economics and Financial Analysis, based in Australia. We featured Part 1 in Episode 91, in which we primarily discussed the future of coal fired power in India. In this second part, we expand on the India story and look more broadly at energy transition across Southeast Asia, and consider the outlook for coal, renewables, and nuclear power in China, Japan, Bangladesh, Pakistan, and Malaysia, among others. As he did in Part 1, Tim shares with us in this episode a fascinating set of data on the future of energy in Southeast Asia that is oftentimes at sharp variance with the projections that we hear from energy watchdogs like the International Energy Agency. Tim tells a much more hopeful story about energy transition in the developing world. For example: If you think that China’s building more coal plants means that its coal consumption is going to go up, think again! Energy transition is moving ahead, and will move ahead, much more quickly in Southeast Asia than any of our major agencies project, and that is great news for the climate.
