PV-to-methanol plants may maximize returns in reserve markets

New research from Denmark shows PV-to-methanol facilities may achieve 30% lower levelized cost of methanol through engagement in reserve markets. The researchers examined the ability of a PV-to-methanol plant to contribute to the grid in frequency containment reserves (FCR), automatic frequency restoration reserves (aFRR), and manual frequency restoration reserves (mFRR).

Researchers propose new models for heat pump load forecasting in energy communities

Novel research from Germany and the USA has analyzed the impact of heat pump (HP) integration on the ability of day-ahead load forecasting in energy communities. Using different models, the scientists have also investigated whether HP loads should be forecasted separately from the rest of the household or both together.
