Prospects for Direct Air Carbon Capture and Storage: Costs, Scale, and Funding

| Nov. 30, 2023

Al-Juaied and Whitmore examine the costs and prospects for direct air carbon capture and storage (DACCS), and identify types of funding needed for early deployment for DACCS and building momentum for later widespread deployment. The challenges of implementing DACCS at very large scale further emphasize the need for urgent and widespread action to reduce emissions, which should continue to be the main priority for meeting climate goals.

Harvard Project Co-Sponsors Webinar on Climate and Energy Policy in India

| Apr. 12, 2021

The Harvard Project on Climate Agreements co-sponsored a webinar on March 30, 2021: “The Future of Green India: Energy and Climate Change.” Hosting the event was the Lakshmi Mittal and Family South Asia Institute at Harvard University. The other co-sponsors were the Environment and Natural Resources Program in the Belfer Center for Science and International Affairs, Harvard Kennedy School — and the Harvard University Center for the Environment. The Harvard Global Institute provided support for the seminar and a larger project of which it is part.

How to Globalize Clean Energy

| June 20, 2020

The authors argue that more determined efforts to globalize renewable energy transmission can confer significantly higher economic and environmental benefits from renewables on billions of people. This can be done by exploiting spatial differences between electricity loads and net renewable generation across time zones (temporal arbitrage) and latitude (seasonal arbitrage). Using very long distance, ultra-high voltage (UHV) transmission infrastructure, temporal and spatial arbitrage can move low-cost clean electricity from areas with excess capacity to high demand zones in other countries and even continents.

Geopolitical and Market Implications of Renewable Hydrogen: New Dependencies in a Low-Carbon Energy World

| March 2020

To accelerate the global transition to a low-carbon economy, all energy systems and sectors must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, renewable hydrogen is drawing increased attention today as a versatile and sustainable energy carrier with the potential to play an important piece in the carbon-free energy puzzle. Countries around the world are piloting new projects and policies, yet adopting hydrogen at scale will require innovating along the value chains; scaling technologies while significantly reducing costs; deploying enabling infrastructure; and defining appropriate national and international policies and market structures.

What are the general principles of how renewable hydrogen may reshape the structure of global energy markets? What are the likely geopolitical consequences such changes would cause? A deeper understanding of these nascent dynamics will allow policy makers and corporate investors to better navigate the challenges and maximize the opportunities that decarbonization will bring, without falling into the inefficient behaviors of the past.
