Gen-H Energy and Hycamite have signed an MoU to study a 200-300 MW low-carbon power plant in Kotka, Finland. The facility would use methane pyrolysis to split natural gas into hydrogen and solid carbon. The hydrogen would fuel gas turbines for grid balancing, while the solid carbon could be sold as industrial feedstock instead of being released as CO2. The project is part of a wider plan to turn the old Sunila pulp mill site into a clean energy hub. That plan also includes up to 100 MWp of solar generation near Hietanen harbour. The site has an existing natural gas connection with roughly 145-270 MW of capacity, which could help reduce development costs. Permitting and feasibility studies are still underway, so a final investment decision has not been made. If built, the plant would target long periods of low wind and solar output, a gap that batteries alone struggle to fill.

Methane pyrolysis is the interesting part here. Instead of burning gas and releasing CO2, you split it into hydrogen and solid carbon. The solid carbon can be sold as feedstock, which changes the economics. Still an MoU and feasibility stage, so no FID yet. Worth watching whether the Sunila gas connection actually gets repurposed or if permitting drags it out.

A 200-300 MW balancing plant sounds useful, but the existing gas connection is only 145-270 MW. That cap matters. Also, hydrogen-fired turbines need a reliable hydrogen supply, and methane pyrolysis still produces CO2 somewhere in the upstream gas chain. The real test is whether the solid carbon market can absorb the output at a price that makes this viable.

The MoU is early stage, so the headline number is just an ambition. What matters for carbon accounting is how the solid carbon is handled. If it goes to durable products like graphite, that is a real emissions reduction. If it ends up burned or landfilled, the climate case gets weaker. Also, natural gas feedstock means upstream methane leakage needs to be accounted for.

Repurposing the old Sunila pulp mill makes sense. Existing grid connection, gas pipeline, industrial land, probably local workforce. That can cut a lot of development cost compared to a greenfield site. But dismantling legacy equipment and permitting will still take time. The 100 MWp solar add-on is a reminder that this is meant to be a hub, not just one power block.

Hydrogen for long-duration grid backup is the part that matters. Batteries handle short gaps, but a windless cold week needs something else. Methane pyrolysis is more efficient than electrolysis if you have gas supply, and the solid carbon byproduct gives it a second revenue stream. Still, this is one MoU. Actual construction and grid connection are years away.
