pv magazine test: August 2022 results

We present the next batch of energy yield results from the outdoor test field in Xi’an, China. Here, we present the results from August 2022, with analysis from George Touloupas, senior director technology and quality at CEA.

Add batteries for electrolyzer viability

Cheaper electricity is a key component of hydrogen production, as the cost of electrolysis is largely dictated by electricity prices. One solution to achieving cheaper electricity when hydrogen electrolysis is coupled with renewable energy generation is through batteries. But is the cost reduction sufficient? Mehrdad Aghamohamadi, a researcher for Cornwall Insight Australia, investigates.

State-of-the-art assessment of batteries

Batteries are set to drive the energy and mobility transitions. Worryingly, when they degrade early or excessively – particularly because of misuse – it can be costly. Claudius Jehle, the CEO of volytica, explains how a better understanding of batteries can prevent expensive mistakes.

The hydrogen policy pipeline

Though large-scale projects are still somewhat thin on the ground, policymakers in the EU and elsewhere are boosting their expectations for the role of green hydrogen. Building on discussions held at pv magazine’s Roundtables Europe event earlier in the year, Christian Pho Duc, CTO and managing director H2 & PtL projects at Smartenergy Group, told pv magazine that the right set of regulations will be crucial in maintaining momentum.

The green ammonia opportunity

High gas prices have pushed ammonia prices sky-high, reaching $1,600 per ton. At this price, by the end of its contract in 2035, the Beatrice offshore wind farm in the United Kingdom would be more profitable producing green ammonia than electricity if the capture price for electricity is below $114/MWh. Everoze partner David Thomason highlights how designing renewable energy projects for diversified revenue streams such as green ammonia can allow them to capture high electricity prices today, while protecting them from cannibalization tomorrow.

Final thoughts: Now the race begins
