To solve climate change, we must deal with heat

Almost all of the world’s energy use involves heat, from making steel to refrigerating food. Deep decarbonization without breakthroughs in thermal science and engineering seems inconceivable. Three leaders in the area highlight five important topics to explore.

COVID-19 opportunities

The researchers hypothesize outcomes of the pandemic’s unprecedented socioeconomic disruption, and outline research priorities for advancing our understanding of humans’ impact on the environment.

Methane emissions climb

The pandemic has tugged carbon emissions down, temporarily. But levels of the powerful heat-trapping gas methane continue to climb, dragging the world further away from a path that skirts the worst effects of global warming.

Living near oil and gas wells may increase preterm birth risk

New research shows living near oil and gas development in California is a risk factor for preterm birth, the leading cause of infant death in the United States. About 2.1 million Californians live within one mile of an active oil or gas well.

Wirelessly charging electric cars as they drive

Engineers have demonstrated a practical way to use magnetism to transmit electricity wirelessly to recharge electric cars, robots or even drones. The technology could be scaled up to power electric cars as they drive over highways, robots on factory floors and drones hovering over rooftops.

Stuart Macmillan, long-time Stanford teacher, dies at 68

Stuart Macmillan contributed to technologies at Sun Microsystems and was a chief scientist at the National Renewable Energy Laboratory. At Stanford, he co-taught a year-round course on clean energy entrepreneurship.

Immersive spring break course goes virtual

Some 40 students head to snowy Colorado each spring break to study extreme energy efficiency. This March, the class had to swap Rocky Mountain scenery for all-day Zoom sessions.

Water heaters’ methane leaks are high, but fixable

Emissions of methane, a potent greenhouse gas, from water heaters are higher than previously estimated, especially for a new type of heater growing in popularity, a new Stanford study finds. But simple fixes exist.

A better way to build diamonds

With the right amount of pressure and surprisingly little heat, a substance found in fossil fuels can transform into pure diamond.

Tracking power plant emissions in real time

Stanford scientists have developed a precise way to measure U.S. power plant emissions 24/7. The new tool will enable grid operators and big electricity consumers to reduce their carbon footprint in real time.

Global carbon emissions increase

Coal use is down dramatically in the United States and the European Union, and renewable energy is gaining traction. But rising natural gas and oil use in 2019 increased the world's carbon dioxide emissions modestly for a third straight year.

Study casts doubt on carbon capture

Current approaches to carbon capture can increase air pollution and are not efficient at reducing carbon in the atmosphere, according to research from Mark Z. Jacobson. Instead of investing in carbon capture,  Jacobson suggests focusing on renewable options to replace fossil fuels.

New catalyst helps turn carbon dioxide into fuel

Stanford engineers Aisulu Aitbekova and Matteo Cargnello say a new process shows promise in turning the greenhouse gas carbon dioxide back into usable fuels, and yields four times as much fuel as previous approaches.

Q&A: New sources of water with desalination research

A new and ambitious research project looks to develop affordable devices to recycle most of the water we now throw away, as well as to desalinate saltwater. The project’s research director describes the project’s vision and operation.

New ways to find natural gas leaks quickly

Finding natural gas leaks more quickly and at lower cost could reduce methane emissions. Ten promising technologies mounted on drones, trucks and airplanes were tested last year. The results are in.

Generating energy from wastewater

A new battery made from affordable and durable materials generates energy from places where salt and fresh waters mingle. The technology could make coastal wastewater treatment plants energy-independent and carbon neutral.

Steering wind power in a new direction

On a working wind farm, Stanford researchers have shown that angling turbines slightly away from the wind can boost energy produced overall and even out the otherwise variable supply.

Finding and fixing natural gas leaks quickly and economically

From production to consumption, natural gas leaks claim lives, damage the climate and waste money. Research teams at Stanford are working on better ways to find and fix gas leaks quickly and inexpensively from one end of the system to the other.

Solving geothermal energy’s earthquake problem

A geothermal energy project triggered a damaging earthquake in 2017 in South Korea. A new analysis suggests flaws in some of the most common ways of trying to minimize the risk of such quakes when harnessing Earth’s heat for energy.
