Pathways to carbon-removing energy:
- Commercial use of direct air capture machines for fuel synthesis can help pave the way for negative-emission direct air capture and sequestration projects. This news about the air-capture/fuel-synthesis collaboration between Audi and Climeworks is an encouraging sign.
- Thermochemical conversion of biomass also provides an important route to carbon-removing bioenergy + carbon capture and storage. This project in France led by energy major Total isn't planning to capture carbon emissions, but the learning from this project will be critical for future efforts that do incorporate capture systems.
- Bioenergy + surfing for carbon-removing energy systems? Very cool.
- Progress at Berkeley on nanotechnology for artificial photosynthesis
Agriculture and Forestry:
- A blueprint for low-carbon agriculture in California with a number of carbon-sequestration recommendations
- The USDA also released its "building blocks for climate smart agriculture and forestry"
- Providing incentives to restore Grasslands requires measurement and verification protocol, like this one recently released by the Climate Action Reserve.
- Reforestration project takes off in Misssissippi
- ClimateProgress on the soils and climate change.
- China's Great Green Wall projectholds potential for large scale afforestation, but many questions remain unanswered about its long-term impact.
- The potential role of carbon removal as a complement/enabler of continued fossil fuel use has the potential to grow highly contentious in coming decades. John DeCicco provides an interesting perspective on this conversation.
