From Iceland to Alaska to France, NREL geoscientist Amanda Kolker has studied geothermal energy all around the world. After graduating with a bachelor’s degree in geology, Kolker went to study volcano and glacier interactions in Iceland but was quickly distracted by Iceland’s vast geothermal energy systems.
As an earth scientist, climate change has been on Kolker’s radar for most of her life, so studying geothermal energy was the perfect combination of her interest in earth science and passion for tackling climate change. Now at NREL, Kolker has brought her global perspective to help improve our understanding of geothermal resources and expand our utilization of those resources such as for heating and cooling.
Bringing Lessons Learned to NREL
After her travels, Kolker came to NREL to continue combining her passions for geothermal energy and tackling climate change. Kolker has worked on a variety of projects ranging from resource assessments to techno-economic analysis of geothermal district heating systems.
Now, Kolker is working on an exciting new international project, working with partners in Iceland and four other European countries to explore “supercritical” energy resources and systems and apply lessons learned to demonstration sites in Iceland and Oregon. Because supercritical resources may be able to produce 10 times the amount of energy from one well as a typical geothermal plant, it would be extremely beneficial to tap into these resources.
Looking Beyond Iceland
Kolker dedicated the next phase of her career to exploring for geothermal resources, earning a Ph.D. from the University of Alaska. There, she helped develop the lowest-temperature geothermal resource in the world for a combined heat and power microgrid in Alaska.
That system uses one resource to generate electricity, heat greenhouses and log cabins, and cool an ice museum. Her Ph.D. research and subsequent consulting work focused on looking at replicating that approach at other geothermal systems near remote communities in Alaska with high costs of power, high costs of heat, and low energy resilience.
Many years later, Kolker moved to France and witnessed how lower temperature geothermal resources were used for agriculture, industry, and to heat and cool districts. Many European and Asian countries use shared heating and cooling systems; studying these French systems helped Kolker bring key lessons back to the United States.
“If we want to better utilize the vast potential of geothermal energy in the United States, we need a bit of a paradigm shift,” Kolker said. “Renewable heating and cooling technologies should be given the same degree of attention as renewable electricity technologies, as heating and cooling accounts for up to 40% of U.S. energy demand. That demand is still mostly met by combustion of fossil fuels, producing temperatures well above what is typically needed.”

Leveraging Industry Partnerships
Assessing characterization and use of earth’s subsurface resources, she is keeping an eye on the relationship between the fossil fuel and geothermal sectors, as oil and gas companies have useful subsurface data that the geothermal energy sector needs.
She has seen how government involvement in countries like Japan, France, and Iceland have pushed geothermal heat and power projects through to development, and Kolker is excited to see how DOE will continue to help push geothermal energy research to take off even more.
From her global travels, Kolker has been inspired by several things, including:
Collaborations among subsurface industries
Governments taking on risks
Focusing heavily on heating and cooling
Geothermal Combined heat-and-power (CHP) microgrids for energy resilience.
Lotus Cars’ compelling, high-performance electric sports sedan and SUV received a number of fresh updates earlier this week, but packs superior infotainment tech, styling tweaks, and (of course) a mind-bending 905 electric horsepower. (!)
The next update on the list is the addition of 22″, 10-spoke ultralight alloy wheels across the entire Eletre lineup. Both the 600 and 600 SE variants retain last year’s 6-piston fixed front and floating rear brake calipers, while the top-tier 900 model gets a high-performance, 10-piston, carbon-ceramic braking system that’s more than capable of hauling the Eletre SUV down from speed, lap after lap.

They’ll need those brakes, too – because these things are fast, and getting faster with seemingly every new software update. “Things can always go faster,” reads the official Lotus copy. “The new Eletre and Emeya ‘900’ provide unmistakable evidence, representing superlatives in terms of performance. Both rely on a 675 kW (~915 hp) strong dual-motor powertrain.”
Both Lotus 900s can put that power to the ground effectively enough to rocket from 0-62 mph (100 km) in a well under 3.0 seconds on their way to an electronically-limited top speed of 155 mph (256 km/h) in the Eletre, and 160 mph (265 km/h) in the Emeya. The 600s aren’t exactly slow, either, packing 405 kW electric motors (~600 hp) good for 0-60 times in the mid 4s.
Inside, the Eletre and Emeya designs carries over without major changes. Lotus enhanced the features list on various trims. The 600 models now include 12-way power-adjustable front seats with heating and ventilation, as well as 15-speaker audio systems from KEF. The 600 SE further adds a PDLC smart panoramic sunroof, 20-way power-adjustable front seats, front seat massage function, and active rear-wheel steering.
CarNewsChina reports that the updated 900 model builds upon the 600 SE’s new offerings with an intelligent, active anti-roll control suspension system.
Pricing for the 2026 Lotus EVs starts at 538,000 yuan (74,800 USD) in China, and climbs to over 838,000 yuan (116,500 USD) for the top-shelf Lotus Eletre 900 SUV. All models carry the same two-speed transmission and 112 kWh battery (102 kWh in the UK), good for up to 610 km (~375 miles) of driving between charges.
It wasn’t that long ago that a 900+ hp car was a cammy, rough-riding mess of a machine that you could barely take through a drive thru, but could probably land on the cover of a car magazine. Today, that same 900 hp in a quiet, smooth, reliable EV hardly generates a headline. And, almost in defiance of the “everything just keeps getting more expensive” truism, these mind-bending supercars can be had for less than what cars like this used to cost with gas engines and a third of the power.

Electric vehicles have come a long way, but let’s be real—they still have their hangups: “range anxiety,” long charging times, and questions about safety and sustainability. But what if all those worries could be put to rest?
At IAA Mobility in Munich, CATL, one of the world’s biggest battery makers, unveiled a new technology that could revolutionize EVs.
Shenxing Pro: Go Far, Last Long
CATL debuted two versions of its next-gen Shenxing Pro battery. One is all about distance and durability. Picture this: a single charge gets you up to 758 km (or about 470 miles). That’s enough to drive from Houston to Memphis without a single stop. And it’s not just about the distance; this thing is built to last. It promises a lifespan of 12 years or 1,000,000 km, with only around 9% degradation after 200,000 km. That’s a huge leap from today’s EV batteries, which often lose up to 30% of their capacity over the same period.
Fast Charging, Even When It’s Freezing
Tired of waiting around for your car to charge? The second version of the Shenxing Pro is for you. It’s the Super Fast Charging model, designed to get you back on the road in minutes. CATL says it can add a whopping 478 km of range in just 10 minutes under perfect conditions. And here’s the best part: it holds its own in the cold. We all know how much cold weather messes with most EV batteries, but the Shenxing Pro still delivers up to 410 km of range in just 20 minutes at a chilling -20°C. That’s better than many EVs perform in normal temperatures!

No Propagation 3.0: Safety First
Safety is a top concern with EV batteries, especially the risk of thermal runaway—that’s when one cell overheats and triggers a dangerous chain reaction. CATL’s new No Propagation 3.0 platform is engineered to stop that domino effect cold. It uses special fireproof coatings and a cell structure that quickly cools down and relieves pressure. In the rare event of a problem, the battery can still provide stable power for over an hour. That extra time is a lifeline, giving drivers the chance to get to safety and ensuring critical systems like advanced driver-assistance features stay online when you need them most.
Getting Greener, At Scale
CATL is also tackling the sustainability issue head-on. Through a new initiative called the Global Energy Circular Commitment (GECC), they aim to cut the use of new raw materials by half over the next two decades. They’re already a leader in this space, operating the world’s largest battery recycling network. Since 2024, they’ve recycled over 130,000 tons of used batteries, recovering 99.6% of crucial metals like nickel, cobalt, and manganese.
The Whole Package
What’s so impressive about the Shenxing Pro isn’t just one feature—it’s everything working together. By improving range, charging speed, safety, and sustainability all at once, CATL isn’t just fixing a single problem; they’re taking on the biggest obstacles to widespread EV adoption. If these batteries live up to the hype, the next wave of EVs could be more efficient, more reliable, and a whole lot greener.
The bottom line? CATL’s latest battery tech in tandem with other commitments could prove to be the building blocks for the next wave of EVs in Europe and beyond.
