Seasonal thermal energy storage can provide flexibility to smart energy systems and are
characterised by low cost per unit energy capacity and varying applicability to different …

Rapidly decarbonizing the global energy system is critical for addressing climate change,
but concerns about costs have been a barrier to implementation. Most energy-economy …

If goals set under the Paris Agreement are met, the world may hold warming well below 2°
C; however, parties are not on track to deliver these commitments, increasing focus on policy …

Achieving net-zero CO2 emissions has become the explicitgoal of many climate-energy
policies around the world. Although many studies have assessed net-zero emissions …

We simulate pathways for achieving up to 100% renewable energy (RE) electric power
systems for the contiguous United States. Under base conditions, the least-cost buildout has …

Carbon dioxide removal technologies, such as bioenergy with carbon capture and direct air
capture, are valuable for stringent climate targets. Previous work has examined implications …

Determining environmentally-and economically-optimal energy systems designs and
operations is complex. In particular, the integration of weather-dependent renewable energy …

Achieving 100% carbon-free or renewable power systems can be facilitated by the
deployment of energy storage technologies at all timescales, including short-duration, long …

Battery storage is critical for integrating variable renewable generation, yet how the location,
