LDES is a linchpin for achieving a low-carbon energy future. DOE and its partners need to expand the range of demonstration types and extend them to end-users to accelerate learning, adoption, and impact.

Policymakers and industry leaders agree that sustainable aviation fuel (SAF) will be key to reducing greenhouse gas emissions from the aviation industry. There is still time to take the proper steps to ensure the industry does its part to reduce global emissions—but that will only happen once SAF reaches price parity.

Lower carbon steel is vital to the energy transition. It’s a long journey to decarbonize steel, and with competition being fierce, supportive RD&D and trade policies will be vital to success.

Green ammonia has attracted plenty of recent attention. The technology is promising, but cost reductions, demonstrations, infrastructure, and market growth are all still needed if it is to realize its potential.

Policymakers and the aviation industry see hydrogen as a promising low-carbon fuel for aviation. But to make hydrogen-powered flight a reality, they first need to bring down the cost of green hydrogen and overcome aircraft design challenges.

Sustainable aviation fuel (SAF) will play the most significant role in meeting President Biden’s goal of a zero-carbon aviation sector by 2050, but significant progress must be made to scale up production and bring down costs.
