The UK government finally launched its long-awaited hydrogen strategy in mid-August 2021. However, their new “twin-track” hydrogen (H2) plan will only fund small volumes of green H2 produced from wind and other renewables with the bulk coming from “blue” H2 generated from fossil gas and dependent on unproven carbon capture and sequestration (CCS) technologies to reduce emissions. Released days after new studies showing that relying on blue H2 could be worse than burning coal, the plan was met with skepticism from the climate science community. In the next installment in a series on hydrogen’s hype, lead blogger and Energy Transition podcaster Michael Buchsbaum breaks down some of the details.
One widespread objection to renewables is the fact that they need some kind of backup, such as gas or hydro power. But as technologies advance, the possibility of storing electricity generated by renewables seems like not-a-too-distant future. The new concentrated solar power plant in Chile is bringing Latin America to the forefront, says Maximiliano Proaño.
Czech nuclear reactors have so far produced at least 4000 tons of highly radioactive waste. If the number of reactors grows, so will the amount of waste produced. The government has long declared itself in favor of developing nuclear energy even as it still does not know how to solve the nuclear waste problem. Martin Sedlák takes a look.
