We develop, integrate and realise energy systems that work - technically, commercially, safely and in the real world.
Hystream can solve one critical project issue, deliver a product, or take responsibility across the full trajectory. Everything we do is aimed at one safe, reliable and workable system.
Feasibility studies, business cases, subsidy applications, permitting, safety, engineering, commissioning, troubleshooting, training or another critical project component.
From first idea to operation, coordinating interfaces, partners, technology choices, safety, subsidies and delivery.
Hystream products or selected third-party technology, supplied stand-alone or integrated into a complete system.
Clients retain freedom of technology and suppliers. Hystream can lead the complete trajectory or step in exactly where a project needs us most.
We do not start with a preferred technology. We start with the challenge and choose the combination that best fits the site, users, constraints, time and budget.
PV, battery, EMS, flexibility, grid optimisation and more for one company or site.
→Shared generation, storage, energy exchange, EMS, grid solutions and stakeholder alignment.
→Production, compression, storage, distribution, pipelines, HRS and maritime applications.
→Combining electricity, storage, hydrogen, heat and control into one coherent architecture.
→Hystream supports subsidy strategy and applications as part of project development. Recent results include successful SWIM applications for Woerden in 2025 and Ede in 2026, with Ede ranked #1.
2025 - Woerden HRS
SWIM subsidy successfully granted.
2026 - Ede HRS & electrolysis
SWIM subsidy successfully granted - #1 in the ranking.
Hystream also provides training on hydrogen safety and practical application. We offer in-company sessions and contribute to external courses for professionals who need practical, directly applicable knowledge.
Training can cover hydrogen basics, safe use, project interfaces, commissioning and operational awareness - always tailored to the audience and the real-world application.

Hystream successfully delivered an in-house training for Verboon Maasland on the safe use of hydrogen generator sets.
Products grow from real project challenges and can be used stand-alone or as part of a larger system.
Semi-mobile hydrogen production, compression, storage and dispensing platform.
Compact high-pressure mobile hydrogen storage with quick-connect couplings.
Optimises PV and battery sizing including the complete economic and financial optimum.
A project can make perfect sense on paper and still fail without commitment, trust and positive momentum. Hystream manages the dynamics between entrepreneurs, authorities, residents, suppliers and other stakeholders - proactively and reactively.
Operational assets and active developments give us a practical view of interfaces, safety, permitting, commissioning and long-term operation.
Underground hydrogen refuelling station.
1,000 kg/day HRS and AEM electrolysis.
Production and 1.1 km hydrogen pipeline.
One technical question, a product, a stalled project or a complete trajectory - tell us what needs to work.
