ALCHEMHY
ALCHEMHY is an EU-funded project tackling key environmental challenges in the chemical industry by developing electrified, zero-emission production routes for ammonia and methanol, two essential yet highly carbon-intensive chemicals. By integrating renewable energy, green hydrogen, and advanced digital technologies, ALCHEMHY aims to replace fossil-based processes and significantly cut emissions. The project supports the EU’s climate goals and paves the way for a more sustainable, resilient, and energy-efficient chemical sector.

SINNOGENES
Storage INNOvations for Green ENErgy Systems
SINNOGENES will develop an energy storage toolkit specialised in helping energy storage innovations to be efficiently and safely integrated into the energy grid. The project will both assist innovations and demonstrate the efficiency and benefits of energy storage technologies.

FRESH
Formate for Renewable Energy Storage
The FRESH project offers a solution by developing a cost-efficient, competitive CO2 to potassium formate electrocatalytic process using renewable energy and re-electrification of the stored fuel using a fuel cell system. This technology would provide efficient energy storage, sourcing and purification of CO2 and a more stable renewable energy supply and price.
