Gentle Green

Gentle Green developed a new climate, water, and energy system that combines climate and airflow control in a greenhouse with heating and cooling. This allows for closed greenhouses, such that no energy, water or CO2 is lost by opening windows. The risk of death from viruses, bacteria, fungi and pollen is reduced by more than 90%. The overall result is a more sustainable greenhouse with higher profitability and improved yield of healthy food.

Logo Cellcius


Heat is one of the biggest energy needs and is currently supplied by gas. Heat that is currently still mostly extracted from gas. However, a lot of unused residual heat is discharged in the industrial sector. Cellcius‘ heat battery makes it possible to store this residual heat and then later use it for heating homes and homes, virtually without loss in this storage process and over time. The innovative thermal battery is the solution for loss-free transport of residual heat and works with two simple and safe ingredients: salt and water.


Lyv is developing an advanced energy management system (EMS), with which, for example, batteries, boilers and heat pumps can be controlled. By switching the devices on and off at the right moment, overloading of the power grid can be prevented. A phenomenon that will happen more and more often in the future as more and more electric driving takes place and households move away from the gas grid.


XINTC develops and produces innovative modular alkaline electrolysers for the production of hydrogen gas for medium-scale applications, at any desired location. The company’s electrolyser is therefore suitable for converting solar and wind energy directly into hydrogen. As a clean energy carrier, hydrogen is in the international spotlight. Hydrogen makes an important and lasting contribution to reducing our CO2 footprint. The splitting of water into hydrogen and oxygen is an electrochemical process and occurs in an electrolyser. No CO2 is released. For large-scale applications, there is a need for affordable, efficient, sustainable and flexible electrolysis capacity.

New investment in sustainable energy storage

LionVolt, a spin-out of the Dutch Technology Centre TNO has developed a revolutionary type of battery based on 3-D technology and solid-state. These batteries are intrinsically safe, lightweight, load super-fast and have a long-life durability. Solid state has as additional benefit, that a battery cannot catch fire or explode. Goeie Grutten co-financed the early phase of the company. First applications can be expected in the wearables segment, where “wet” lithium batteries are still dominant.

Stichting Goeie Grutten

Recently the website of stichting Goeie Grutten went live. The foundation, with ANBY statut, Goeie Grutten supports long term projects related to sensible, healthy foods with lots of variety and energy transition. We preferably invest in long-term projects and we are always on the lookout for project that help us to achieve our goals
