Boston Metal’s Current Evidence Points To Critical Metals, Not Green Steel

Boston Metal’s public story has shifted in a way that makes the company more credible in the near term, but less sweeping as a green-steel story. The company is still built around molten oxide electrolysis, or MOE, an electrically driven process for reducing metal oxides without coal. The near-term commercial ... [continued]

Thawing Permafrost Not Only Emits CO2, It Absorbs it Too, Shows Landmark Study

Thawing permafrost is considered a growing source of greenhouse gases as our climate warms and releases ancient carbon once stored in the frozen soils. But a new study reveals an overlooked plus side: the process will also trigger a removal of emissions from the atmosphere as the landscape thaws. The research, published in the journal […]

Climate Solutions Need To Pass Three Tests Before They Deserve Policy Or Capital

A lot of transition analysis gives too much credit to technologies that can be made to work and not enough scrutiny to whether they matter. The difference shows up across carbon capture hubs, synthetic fuel claims, small modular reactor schedules, cement decarbonization pathways, aviation fuel projections, ammonia shipping forecasts, grid ...

Solar With Firming Now Beating Gas In Asia, & EVs Could Save Region $350 Billion A Year

While the solar industry really got its jumpstart in the US, and then grew to a significant level in Germany, it’s China that completely exploded the industry while driving costs down to unbeatable levels. The same thing basically happened with electric vehicles as well. However, there’s still much more that ... [continued]

Molecules Do Not Disappear. Their Market Shrinks.

A lot of energy-transition arguments begin with today’s fossil fuel demand. Coal, oil, and gas still dominate global primary energy, so it is tempting to draw a straight line from the current fuel system to a future molecule system. Replace natural gas with hydrogen. Replace bunker fuel with ammonia or ... [continued]

Solar Generation in CAISO Surpassed Natural Gas in the First 5 Months of 2026

In the first five months of 2026, utility-scale solar generation surpassed natural gas generation in CAISO. Solar electricity generation in the California Independent System Operator (CAISO) over the first five months of 2026 increased 21% compared with the same period in 2024, and natural gas generation decreased by 60%, data ...

This ultrasonic espresso method uses 75 percent less energy and tastes just as good

BY THE OPTIMIST DAILY EDITORIAL TEAM So many of us participate in the same morning coffee ritual: the machine warming up, the pressure building, the crema settling into the cup. It’s such a fixed sequence that it’s hard to imagine any part of it changing. But against the odds, researchers at the University of New […]

Fossil Fuels Are 40% Of Freight Shipping Tonnage, But Half Its Fuel Use

Maritime fuel debates usually start with the wrong object. They look at today’s bunker fuel demand, line up replacement molecules, and ask whether ammonia, methanol, hydrogen, LNG, biofuels, or synthetic fuels can scale far enough to replace it. That sounds like a practical question, but it skips the larger one: ... [continued]

How reflective roof paint is cooling homes across Africa

BY THE OPTIMIST DAILY EDITORIAL TEAM The question seemed reasonable enough: what heat adaptation interventions were already working in Africa’s low-income communities? Lara Dugas, an epidemiologist, and climate scientist Mark New had received funding from the Wellcome Trust’s HeatNexus initiative to evaluate what was in place. When they went looking, they found nothing. “The initial […]
