U.S. Military figures show the resupply of liquid fuel and drinking water for troops in-theatre costs about 4 lives for every 100 convoys. It makes an army more vulnerable and limits movement. That’s why the U.S. Department of Defense is looking at very small modular nuclear reactors (vSMRs): sub-10MW nuclear units. They are already being designed, built and tested. If successful, no refuelling is required for years and the units can be … [Read more...]
South Korea’s nuclear ambitions face safety, quality issues
Dan Yurman summarises the regulatory, academic and press coverage of serious delays to South Korean nuclear reactors being built for the UAE. According to reports, these were caused by having to replace substandard components in reactors located in both South Korea and those planned for the UAE. There are problems with staff training too. South Korea recently completed the US NRC safety review process for its 1400 MW design. But the author asks … [Read more...]
2009 to 2017: solar, wind costs plummet, hydro steady, nuclear up
Between 2009 and 2017 prices dropped 76% for solar panels and 34% for wind turbines. Hydro and nuclear struggle to cut costs; as mature technologies, most of the efficiencies have already been squeezed out already. Also, they are difficult to productise and scale; dams (definitely) and nuclear plants (somewhat) are one-offs. In contrast, solar panels and wind turbines are far easier to productise and then mass produce. It’s why wind overtook … [Read more...]
Leaked German govt report: emissions target will be missed despite on-target renewables
A leaked draft of Germany’s Energiewende Progress Report 2019, due to be released by the economy ministry in May or June, predicts the country will miss its targets for reducing energy use and greenhouse gas emissions by wide margins. This is despite the inevitable emissions reductions due to the 2009 recession and being on track for renewables. If no other measures are taken Germany will reduce emissions by 33% by 2020, falling short of the … [Read more...]
More nuclear means more waste disposal: the options, science, engineering
Public concern about nuclear power goes beyond an accident at a live plant. What do we do with the nuclear waste? If nuclear is to grow to become a major replacement for oil and gas the question must be answered. James Conca reviews the different methods that have been seriously considered: shooting it into space, burying it in deep sea trenches or under ice sheets, transmutation, or simply digging it even deeper underground. … [Read more...]
Developing World: cashflow analysis shows gas, coal far more profitable than clean energy
80% of future energy infrastructure will be built in the developing world. Schalk Cloete has already written for us on the purely economic viability of developed world onshore wind, utility-scale solar PV, nuclear, natural gas and coal. He now presents his detailed cashflow analyses of the major generator technologies applied to the developing world. Because costs tend to be much lower the returns are higher. But gas and coal still easily … [Read more...]
SMR reactors: questions the “new nuclear” industry needs to answer
The new energy world is full of ambition about future developments, not least nuclear. At some point hard questions have to be asked and answered. Dan Yurman is asking questions about next generation Small Modular Reactors (SMRs). For example, why take on the unknown material and regulatory risk of SMRs over the known risks of proven LWRs? Which governments and/or investors will back the $500m needed to get an SMR into production? Where are the … [Read more...]
Next generation nuclear: 25MW, smaller, safer, can be sited anywhere
Dan Yurman looks at plans for Small and Micro Nuclear Reactors. A UK report on Micros that generate 30MW says it’s an opportunity for the country to own the IP and export units that are simple in design, factory constructed and capable of being sited in remote locations. Given the rough ride nuclear can get, the report warns that progress will depend on political, regulatory and financial support. Meanwhile, in the US, Westinghouse will have a … [Read more...]
Small nations have big plans for nuclear energy
Dan Yurman looks at how small nations are trying to increase their nuclear supply. Romania has the US and China both pitching for business. The Czech Republic is still vague about giving electricity price guarantees, something that caused the collapse of a $25bn nuclear tender in 2014. Ukraine looks at Small Modular Reactors. The author starts with the Baltics – net importers of electricity – and Estonia’s ambition to redress that balance using … [Read more...]
Can nuclear compete for a bigger role in the transition?
With plans to phase out coal-fired generators in most of Europe, nuclear is trying to compete with gas to become the most viable baseload power source to accompany renewables on the path to net-zero emissions. Both technologies have their advantages. Gas is competitively priced while nuclear generates power with almost no emissions. Right now, gas's cost advantage is evidently great enough to tip the balance. If nuclear advocates are to … [Read more...]
UK nuclear plans are in tatters. But current incentives help gas, not wind and solar, step into the gap
The scrapping of plans for a new nuclear power station in Cumbria and the suspension of work on another in Anglesey have put the brakes on the UK’s nuclear future. But the government appears more keen to fill the gap with gas rather than renewables. David Toke of Aderdeen University criticises the current incentives and regulations and makes the case for wind and solar. … [Read more...]
Nuclear power at the mercy of government subsidies while costs remain high
What affects the profitability of an investment in nuclear energy? What are the risks? Energy researcher and analyst Schalk Cloete presents his latest paper on the matter. He looks at the various effects on nuclear power investment, including the rise of other competing renewable energy sources, and the changing price of energy. *This article is brought to you via our new author platform. If you have an article you want to submit to us for … [Read more...]
EU electricity supply from RES off course for 2030 – so is it more nuclear or gas?
Last year’s strong reported performances for the share of clean energy in the UK and German energy mixes paint a rosy picture. It is the result of billions in investment and strong signals from Brussels and the COP series. Looking more broadly across the EU though, the share actually decreased by 17% from 2016 to 2017. Furthermore, due to lack of investment stretching back as far as 2011, the rate of growth has dropped significantly putting RES … [Read more...]
Nuclear – critical choice for 2050
As the urgency of the climate crisis becomes more obvious, nuclear power is drawing another look. The power sector needs to develop to meet climate targets. Renewables (RES) have taken significant share of the energy mix in recent years but going further means securing far more investment and solving the complex challenge of integrating variable power. There is a need for alternatives to run alongside RES, keeping us on track. Matthew Wald from … [Read more...]
Britain has shifted 30% of its electricity away from fossil fuels in just nine years
Britain’s extraordinary energy transition is in part down to increased energy efficiency: put simply, less electricity was needed, whatever the source. But coal is still essential during spikes in demand. Given coal generation is due to be phased out by 2025, the country will need to find alternative power sources to cope during extreme weather events. And that overall decline in electricity demand is sure to be reversed as more vehicles and … [Read more...]
