Reactors you can ship in a container — powering mines, bases, and communities off the grid Not all energy challenges are about scaling up. For remote mining operations in the Arctic, forward military bases, island communities, industrial facilities in off-grid locations, and emergency power restoration after disasters, the question is not how to power a […]

Marine energy’s long road to commercial viability — and why it may finally arrive The world’s oceans contain an almost unimaginable quantity of kinetic and potential energy. Tidal currents driven by the gravitational pull of the moon, wave energy driven by wind across vast ocean fetches, and ocean thermal gradients represent renewable resources that, unlike

The audacious plan to harvest sunlight in orbit — 24 hours a day Solar panels on Earth face an unavoidable problem: night. For roughly half of every 24-hour period, the sun is below the horizon, and even during daylight, clouds, atmosphere, and angles reduce the energy reaching ground-level panels. In space, none of these limitations

Enhanced geothermal systems are unlocking heat beneath our feet — wherever we need it Traditional geothermal energy is location specific. It works where the Earth’s heat is close to the surface — Iceland, the western United States, East Africa, Indonesia, and other volcanically active regions. Globally, only about 15 GW of geothermal capacity is installed,

How networks of home batteries and smart devices are becoming the grid’s most flexible resource Across suburban areas, millions of home solar systems, EV chargers, battery storage units, water heaters, and smart thermostats are quietly accumulating grid-interactive capability. Individually, these devices represent modest electrical loads. But aggregated through software platforms and coordinated by advanced algorithms,

How old technology is finding new life in the renewable energy transition In the global conversation about energy storage, the spotlight shines almost exclusively on batteries — lithium-ion, sodium-ion, flow chemistries, and the latest innovations. Yet the technology storing most of the world’s grid energy is none of these. It is pumped hydroelectric storage, and

Iron-air batteries, flow batteries, and the technologies reshaping how grids store clean energy The rapid growth of solar and wind power has created an unprecedented demand for energy storage. Lithium-ion batteries — refined through decades of electric vehicle development — have become the dominant short-duration storage technology, with costs declining more than 85% since 2010

How the world’s most widely produced chemical could become clean energy’s global currency Hydrogen is widely described as the fuel of the future, but it has a problem: it’s extremely difficult to move around. The lightest element in the universe, hydrogen requires either enormous pressure, cryogenic temperatures approaching –253°C, or expensive specialized infrastructure to transport

Metal hydrides, chemical carriers, and the materials science revolution in hydrogen storage Hydrogen is the lightest element in the universe and contains three times the energy per kilogram of gasoline — but per liter, it stores dramatically less energy than liquid fuels. This density problem, combined with the safety challenges of handling highly flammable gas
