China is the world’s largest market for EVs, estimated to reach ~$360 billion by 2030.This is driven both by the sheer size of China’s population and economy, as well as the Chinese government’s focus on developing the EV market. Here, we profile a few of the top EV players in China.

NIO

NIO (NYSE: NIO) is a Shanghai-based EV manufacturer with ~$2.5B in 2020 revenues. Launched in 2014, it currently competes in the premium end of the market, vying against Tesla and BMW, with its electric SUVs and recently unveiled sedan. It still has yet to turn a profit, though industry…

In recent years, there has been a growing plethora of vertical farming companies: Gotham Greens, Bowery Farming, and Aerofarms to name a few. They have attracted millions in investment as they sell the promise of a sustainable agriculture revolution. The question is, do they live up to their hype, environmentally-speaking?

Vertical farms are “plant factories” that grow crops at scale indoors, stacked in vertical layers. Rather than growing plants in soil, vertical farms use hydroponics (i.e., growing plants in nutrient-rich water), aeroponics (i.e., delivering nutrients to plants via spraying water mist), or aquaponics (i.e., growing crops in an aquatic environment…


Grid scale storage refers to energy storage systems that are used by electric utilities. Technologies for grid scale storage range from pumped hydroelectricity to flywheels to large-scale lithium-ion batteries.

Effectively and widely deploying grid scale storage is a crucial part of grid decarbonization. Grid scale storage can help solve the problem of solar and wind power intermittency, allowing for greater deployment of renewable resources. By improving the reliability of solar and wind, grid scale storage can replace the need for fossil fuel powered peaker plants. …

What is carbon sequestration?

Carbon sequestration, or carbon capture and storage (CCS) is the process of taking carbon dioxide out of the atmosphere and storing it. CCS is a critical part of the solution suite for limiting global warming to1.5°C above pre-industrial levels. The Intergovernmental Panel on Climate Change (IPCC) includes CCS in 3 out of its 4 pathways to 1.5°C. CCS can allow for a more gradual and therefore easier path to decarbonization.

In this article, we are focusing on CCS. A related process, carbon capture and utilization (CCU) refers to taking carbon dioxide out of the atmosphere and reusing it, for example…


The shift from internal combustion engines to electric powertrains is one of the largest automotive transformations expected in the coming decade. But while Tesla sightings are becoming normalized, few people have laid eyes on a FCEV. As of April 2021, there were only 9,961 passenger FCEVs sold or leased in the U.S., compared with more than a million BEVs on the road. What has prevented higher penetration of FCEVs so far, and what can we expect in the next ten years?

What are FCEVs?

FCEVs are electric vehicles powered by hydrogen. Hydrogen is stored in a fuel tank, and then routed to a…

What is the impact of food waste on climate change today?

The statistics we have on food waste shocked me when I first heard them. Globally, around 30% of food produced is never consumed. In the U.S., this number is closer to 40%.

Food waste matters in the fight against climate change for a number of reasons. Wasting food means that the greenhouse gasses associated with producing, harvesting, processing, and distributing the food were unnecessarily emitted. Resources such as land, fertilizer, and water that could have been…

Why is tropical forest reforestation important?

Tropical forests are closed canopy forests growing near the equator that have heavy rainfall throughout the year. Forests are a significant carbon sink as trees store carbon through photosynthesis, with tropical forests containing around 25% of the world’s carbon. The Amazon Basin alone may hold 90–140 billion tons of carbon, equivalent to 9 to 14 decades of human carbon emissions.

Tropical forests once accounted for 12% of the world’s landmass, but now only account for around…

What are onshore wind turbines?

Onshore wind turbines are a source of energy generation that converts the kinetic energy of wind into electricity. As opposed to offshore wind turbines which are located on open water, onshore wind turbines are located on land, making them significantly less expensive to install and maintain but also limiting their size compared to offshore turbines.

Onshore wind turbines are one of the fastest growing energy sources in the world globally (~20% CAGR increase in global installed…


Mobility-as-a-Service, or MaaS, describes digital platforms that integrate multiple modes of transportation. Through a single service, users can access end-to-end trip planning, booking, and payment for all the transit options that they need in a particular area. More concretely, imagine a smartphone app that you can use to seamlessly switch from a ride share to the subway to a public bike, without having to change payment methods, and with all transit information available through the same platform.

The MaaS space is still relatively nascent, particularly in the US. Proponents of MaaS argue that the technology would bring a myriad of…
