The System Case Against Hydrogen for Grid Storage

Every time hydrogen is critiqued as an energy carrier for the power sector, the same question reappears. If not hydrogen, where does long duration storage come from? I received it related to my recent critique of Germany’s attempt to force the EU to double green hydrogen and synthetic fuel quotes … [continued]

Rye On A Roll: US Developer Greenlit For Massive Pumped Hydro Energy Storage Project On…

The proposed Goldendale Energy Storage Project in Washington State is one step closer to adding 1.2 gigawatts of pumped hydropower storage to the nation’s renewable energy profile.

Google Gemini generated this infographic contrasting the immediate energy delivery of electricity system investments with a currently unused hydrogen pipeline, both costing ~€1 billion.

The Opportunity Costs of Germany’s Hydrogen Backbone

Germany has now completed and pressurized roughly 400 km of hydrogen backbone pipeline with no connected suppliers and no contracted customers, a pipeline from nowhere to nowhere. The infrastructure exists and is operational, but no hydrogen is flowing to anyone who has agreed to pay for it. This is not … [continued]

Slide from Michael Barnard's presentation to the University of Twente's Climate Event

The Short List of Climate Actions That Will Work

A few months ago, I was invited by Dr. Sebastian Husein of the Battery Centre Twente to speak at the University of Twente’s 2025 Climate Event, a hybrid discussion with multiple speakers engaging with an audience of academics in the Netherlands and neighboring countries. That event occurred on November 5th, … [continued]

Chatgpt generated: Economic and operational contrast between molten salt storage and simpler, lower cost solid storage systems

Why Molten Salt Won’t Be the Future of Industrial Heat Storage

Molten salt has long been positioned as the workhorse of high temperature thermal storage. Its story began with research in the 1980s and early deployment in Spanish parabolic trough plants in the 2000s. The technology was appealing on paper. A mixture of sodium and potassium nitrate has a high heat … [continued]

Canada’s $456B Megaprojects List: Building The Past Or Electrifying The Future?

Canada is preparing to spend potentially half a trillion dollars on major infrastructure projects that will shape the economy and society for decades. The list spans ports, high speed rail, hydroelectricity, nuclear, mining, oil and gas, carbon capture, offshore wind, and transmission. On paper it looks like a bold nation … [continued]
