最近可再生能源成本的急剧下降表明，通过电力制气的可再生能源制氢过程可能会变得更加经济。在这里，我们从一个投资者的角度来研究这种替代方案，他考虑将可再生能源与高效规模的电力到天然气设施相结合的混合能源系统。可以实时优化可用容量，以利用电价波动和间歇性可再生能源发电。我们将我们的模型应用于德国和德克萨斯州的当前环境，发现可再生氢在利基应用中已经具有成本竞争力((sic)3.23 kg(-1))，尽管还没有达到工业规模的供应。然而，如果最近的市场趋势在未来几年继续下去，预计这一结论将在十年内发生变化（原文为2.50公斤）。
The recent sharp decline in the cost of renewable energy suggests that the production of hydrogen from renewable power through a power-to-gas process might become more economical. Here we examine this alternative from the perspective of an investor who considers a hybrid energy system that combines renewable power with an efficiently sized power-to-gas facility. The available capacity can be optimized in real time to take advantage of fluctuations in electricity prices and intermittent renewable power generation. We apply our model to the current environment in both Germany and Texas and find that renewable hydrogen is already cost competitive in niche applications ((sic)3.23 kg(-1)), although not yet for industrial-scale supply. This conclusion, however, is projected to change within a decade ((sic)2.50 kg(-1)) provided recent market trends continue in the coming years.
